1.1.1 General safety information

All ALKIN air and gas compressors are designed and manufactured with equipment & components that allow safe operation of the compressors. It is the user’s responsibility however; to safely operate and maintain the compressor, observe the rules and instructions, as well as the local safety codes, to minimize the risk of accidents and injury. The following safety precautions are offered only as a guideline, and it is recommended to follow them along with the locale safety codes and regulations.

Those who have been trained to do so, and who have read and understood the contents of this manual should only operate these compressors. Failure to do so will increase the risks of accidents and bodily injury.

Never start this compressor unless it is safe to do so. Do not operate it with known unsafe condition. Tag the compressor and render it inoperative by disconnecting the power supply, so that others who may not know of the unsafe condition will not attempt to operate it until the unsafe condition is corrected.

Install, use and operate this air compressor only in full compliance with all pertinent O.S.H.A. Requirements

(USA&Canada), and all relevant Federal, State and local codes and regulations.

Do not modify this compressor and do not use beyond the specified limits and speeds except with prior written approval of ALKIN.

1.1.2 Pressure release

Have the safety valves tested periodically by certified service personell and in conformity with the specific manufacturer’s instructions and local regulations. Do not open the oil filling plug or any other connection, tube, hose, fitting, valve etc. when the compressor is running or when it is standing by (waiting for the pressure switch signal to re-start). Switch off the main electrical switch, shut off the discharge valve and vent all pressurized sections before attempting to dismantle such components.

Keep all persons away from the discharge opening of hoses, tools accessories during venting. Do not use air pressure above 2 Bars (30 Psi) for blow cleaning purposes, and without use of proper protective equipment as per OSHA

Standard Section 29 CFR 1910.242 (b). Do not engage in horseplay with hoses as serious injury or death may result.

Drain daily the condensate from the air receiver, as it may accelerate the internal rusting and corrosion of the receiver.

1.1.3 Fire and Explosion

Clean up oil spills immediately, if and when it occurs. Shut off the air compressor and allow it to cool. Keep sparks, flame and other sources of ignition away and do not allow smoking in the vicinity when checking, and draining or adding oil. Do not permit liquids such as airline anti-icer system anti - freeze compound, or oil film or any other combustible substance to accumulate on any external or internal surfaces of the compressor. Wipe down with aqueous industrial cleaner or steam to clean as required. Do not use flammable solvents for cleaning purposes.

2.0 General information on W4 series 4 Stage compressors

2.1 General

The W4 Series compressors are four stage , reciprocating type, aircooled, splash lubricated compressors.

The pressure range these compressor operate vary depending on the cooling system and valve heads installed and it ranges from 100 Bars (1500 psi) to 415 Bars (6000 psi). Do not attempt to modify a compressor to operate at a higherpressure range without written approval of Alkin. Failure to do so may result in heavy damage to equipment, injury or death.

The compressor is built with oversize intercoolers and an aftercooler to allow superior performance, longer life and lower operating & discharge temperatures.

The first and second stage cylinders are built in a common cylinder assembly (see Figure 1 in this section). The first stage compression occurs in the up-stroke of the piston, and the second stage compression in the down-stroke.

Figure 1

The third and fourth stage compression takes place in the up-stroke of 3rd and 4th stg steeple piston working in its crosshead guide and cylinder.

The W4 series compressors are equipped with oversize copper intercoolers between the 1st & 2nd and 2nd & 3rd stage cylinders and stainless steel intercooler between the 3rd and 4th stage cylinders and stainless steel aftercooler downstream

W 4 S E R I E S

H I G H P R E S S U R E B R E A T H I N G A I R C O M P R E S S O R the 4th stage cylinder. A moisture trap (or condensate separator) is installed Downstream the 2nd & 3rd stage aftercoolers and downstream the aftercooler. Each of these moisture traps is connected to automatic drain valves that periodically open and drain the condensate in these traps. The opening intervals and duration is set by a time control relay found in the electrical control panel of the compressor (see the controls section). This time relay can be adjusted for both functions. Normal – factory set- values of the drain valve timer are 15 minutes closed, and 6 seconds open operation.

A safety valve is installed between each stage and after the final stage to protect the system against an unexpected pressure rises due to a malfunctioning valve or component. These safety valves must be inspected periodically to insure proper operation and set pressure verification (see the maintenance schedule for inspection periods).

The W4 series compressors incorporate stainless steel valves on all 4 stages. They are designed to have an onobstructed passage of air with no pressure loss; they are easy to maintain and replace. Particular attention must be paid to valve maintenance, as these valves are the basis for proper operation of the compressor package. Do not use oils other than the recommended oils in this manual for keeping the valves clean and free of carbon collection. Unsuitable oils will cause carbonization which will collect on the valve discs and springs, resulting in improper sealing of valves, This will increase the operating temperatures, generating a chain reaction for further deterioration of the oil and valve operation.

Lubrication is created by dipstick found in the bottom of the 4 th stage connecting rod. While the crankshaft rotating, the connecting rod reciprocates and the dipstick enters the oil bath in the bottom of the crankcase; while coming out of this oil bath, the dipstick splashes oil to the moving parts of the compressor. Efficient oil wiper rings control the economical lubrication of the system.

See the process and instrument diagram to study the general system layout and operation sequence

2.2 P&I (Process & Instrument) Diagram

The following process and instrument diagrams are prepared with the drawing of the physical components rather than pneumatic symbols, in order to facilitate the understanding of the system by users who are not specifically trained to understand pneumatic symbols.

Some compressors are designed to operate at a “single pressure”

(see P & I diagram Figure 3). This is, when the

compressed air is used to fill all the cylinders to that single pressure. On some other systems there might be different cylinders that need to be filled to two different pressures. For instance some cylinders are filled to 3200 psi, and others to 4500 psi. In such applications “dual pressure” controls are used to operate the compressors to the

selected pressure between the two available set pressures see P & I diagram Figure 4).

Figure 4

2.3 Principles of Operation

The P & I diagram have to be reviewed carefully to understand the principle of operation. The air is drawn at atmospheric pressure, through the inlet filter (see Figure 2 ) into the 1 st stage cylinder on the down-stroke of the piston (see Figure 1 in section I-4). The up-stroke motion of the piston will cause compression and the air will be forced out of the cylinder through 1 st stage discharge valve and than the manifold ( Figure 2 ). Air will than pass through the intercooler tubes between the 1 the 2 nd st and 2 nd stages and into the 2 nd stage compression chamber. Note that

stage compression chamber, unlike the other 3 cylinders, is the volumetric difference between the 2 nd stage cylinder walls and the lower section of the piston (see Figure 1 in section I-4). On the down-stroke of the same piston, the air contained in the 2 forced through the 2 nd manner to the 4 th nd stage compression chamber is compressed to the second stage pressure and

stage valves + 2 nd stage intercooler + 2 the 3rd stage cylinder. Here, the air is compressed to the 3 rd nd stage moisture separator + 3 rd stage inlet valve into

stage compression level. The air than is forced in similar

stage cylinder where it is compressed to the final pressure level and forced out to the aftercooler, moisture separator, to a pre-filter unit where it is cleaned of any particles and oil content, than passing through a check valve enters the purifier chamber, where it is purifier and prepared to be used for breathing purposes. A priority (or minimum pressure valve) is installed downstream the purifier; this valve prevents the air to exit the purifier until the pressure builts to approximately 180 bars (2610 psi), a pressure level where the purification process is more efficient than at lower pressures. The air is than ready to be directed to a filling panel and with proper connections to the cylinders to be filled.

13

W 4 S E R I E S

H I G H P R E S S U R E B R E A T H I N G A I R C O M P R E S S O R

The intercoolers and the aftercooler are designed to dissipate the heat generated from the previous compression cycle, reducing the air temperatures, allowing the water vapors to condensate and settle in the bottom sections of the moisture separators. The 3 moisture separators and the pre-filter unit are equipped with an automatic drain valve. The drain valve is a 3 way pneumatic valve controlled by a 3 way solenoid valve installe on the piping adjacent to the centrifugal unloader. This solenoid valve sends or removes the control air from the drain valves, thus letting them to open or close. The solenoid itself is controlled by a sequential timer relay in the electric panel.

The dual time adjustmens on this relay allows to adjust the duration (t1~ 15 min) during which the solenoid will remain energised (=the drain valve will remain closed), and the length of time (t2~ 6 seconds) during which the solenoid will become de-energised (=the drain valve will open and perform the drain function).

The compressor starts and stops with automatic regulation by a pressure switch (see section 2.5.1

for adjustments and functional details).

The oil level of can be monitored on a sight gage provided in the right bottom side of the crankcase (next to the

Low oil level switch) – see Figure 2. The oil level can also be checked through the dipstick found in the filling plug.

In principle the level of oil has to be up to the filling plug thread. A low oil level switch is provided to protect the compressor from lack of oil in its sump. When the oil level drops, the switch cuts off (opens its contacts), thus cutting the control circuit of the motor starter, and stops the electric motor. A signal lamp is provided to indicate that the motor stopped as a result of low oil level.

2.4 Description of Major Components

2.4.1 Major Components - Compressor Unit

Crankcase:

This is the frame that holds everything on it. It contains the oil that lubricates the system. The cylinders are mounted on it. The crankshaft is inserted into the bearing housings which is an integral part of the crankcase.

There is no maintenance or repair works that need to be done on this part; it needs to be cleaned inside when the oil is changed. Due to its unique overhung design, the cleaning inside the crankcase is made possible as the cover does not carry the bearing housings as in most other type compressors.

Crankshaft:

It is overhung type; that means the bearings are on one side, and the crank pin (where connecting rods are mounted) are on the other side. This unique feature allows usage of single piece connecting rods which are far more accurate and safe than split con rods. Large bearings in conjunction with low speeds, allow very long crankshaft life.

Connecting Rods:

There are three connecting rods which are similar in the 1st/2nd stg and the 3rd stage, and is different on fourth stage. The 4th stage con.rod has a stick extending in the bottom that enters the oil sump at every rotation, thus creating splash of oil that lubricates the system. It is equipped with high quality copper- bronze alloy plated inserts that serve as journal bearings. These journals wear in time and therefore the con rods will require replacement or renewal of its bushings in when wears.

Cylinders:

They are cast separately and are made of high grade casting materials, machined & honed to fined tolerances for long service life. When worn, they will need replacement. The compression cylinders on the 3rd and 4th stages are mounted on guide cylinder to guide the crosshead piston ass’y.

Head Assembly:

The head assemblies are the cover plates and the valve assemblies housed inside; these assemblies are mounted on top of the cylinders. The valve assemblies inside the covers need to be maintained periodically; they need to be opened and cleaned; if valve disks or springs are worn, they need to be replaced. See valve maintenance section of this manual for futher details.

H I G H P R E S S U R E B R E A T H I N G A I R C O M P R E S S O R

Beather:

All piston type machines have some compression leak through the rings into the crankcase; to prevent pressure build up in the crankcase, a breather system is pr ovided to allow the crankcase to “breath”. In the air compressor the crankcase is connected via a copper tube to the inlet from where the breathing is made possible, or a breather device is installed on the crankcase to vent the pressure from within the crankcase. In the gas compressors the crankcase is piped to the inlet

.

2.4.2 Major Components – System

The Canopy:

The semi open canopy is designed to carry the various components, the electrical panel, and permits lifting the system through the pallet jack slots. It is painted electrostatically for extended life. It has four easily removable door panels to easily and quickly access all parts of the package.

The Sub Base:

This is the base carrying the motor & compressor units; it is supported on four vibration mounts; this base plate is separate from the canopy and with this unique design no vibration is transmitted to the canopy. The vertically mounted compressor / motor assembly, is a belt driven system; the belts are automatically tightened by the weight of the motor on which it is mounted. This unique device saves to pay extra attention to the belt tightening on W4 series machines.

The Electrical Panel :

It is mounted inside the fan duct on the top section and can be accessed by removing the top door. It accommodates all the electrical gear to start the motors and control the system.

Pressure Switch:

This unique Alkin device is installed on the right door, this switch both indicates the purifier pressure, and the set pressures on its dial, while serving as a double circuit pressure switch. It controls the start-stop operation of the compressor. The pressure-sensing end of the pressure switch is connected to a port on the purifier; when the pressure inside the purifier reaches the set pressure, it cuts off the contnrol circuit, and stops the electric motor.

Automatic Drain Valves:

The automatic drain incorporates a small piston with high pressure in the bottom, and low pressure on top; the surface where low pressure acts on is larger than the surface where the high pressure effectively acts on the piston.

Therefore the force on the top is larger and causes the piston to sit and seal the high-pressure vent port. The drain valves are controlled by a solenoid mounted on the pilot valve fitting. It receives compressed air from the 2 nd stage moisture separator and sends it over the 4 drain valves forcing them to close. When the solenoid is de-energised, it removes the control air over the top of the drain valve pistons, allowing the high pressure acting from the botto of the pistons, to open and perform drain operation.

Note

Do not run the compressor on wooden pallet where the unit is mounted for transportation purposes.

2.5 Description of Controls

2.5.1 Compressor Controls

The W4 Series compressor may operate with the following two controls:

Automatic Start – Stop Control (Single Pressure Only):

This is the standard control type for all single pressure compressor systems. With this type of control, once the compressor is manually started, it will run till it reaches the high set pressure where is will automatically stop (the pressure where the motor will cut-out); after the pressure drops to the low set-pressure (the pressure where the motor will cut in), it will automatically re-start. This control system is standard on all single pressure compressors.

Manual Start – Automatic Stop Control (Dual Pressure Only):

This control is used on compressors with dual pressure controls. The dual pressure systems have two cut out pressures (at which level the motor will be stopped): One is the low cut-out pressure (for example at this mode, the compressor will stop at 3200 psi), the other is the high cut-out pressure (for example 4500 psi).

With this type of control, the compressor will always have to be started manually; there is a valve on the filling panel which allows the operator to select between low and high pressure cylinder filling depending on the type of cylinders be ing filled. If the lever is at the “high pressure” mode, the pressure switch wil sense the high pressure and will cut out at that pressure (for example at 4500 psi). When the lever is set to the low pressure mode, an electropneumatic valve will be activated, enabling the low cut-out pressure circuit of the pressure switch to control the system; when the low cut out pressure (inthis example 3200 psi) is reached, the pressure switch will cut out the motor.

Pressure Swtich:

The W4 series compressors are controlled by a pressure switch that cuts off the motor control line when the operating set pressure is reached; it cuts in when the pressure drops below the pre set low pressure limit, starting the motor again. When the main motor is stopped by the pressure switch, the two top fans keep working for an additional period of time (generally 4 to 10 minutes depending on the ambient temperatures); this is controlled by a timer (0-30 min setting range). This feature is incor-porated in the system to permit good cooling even after the compressor stops, thus allowing the next start in a cooler state. This improves the valve life and the performance, it protects the lubricant and prolongs the overall life of the compressor. On diesel engine driven compressors, a constant speed control system is added to the package; this includes head and discharge unloaders for the compressor unit, and an unloading system which allows the compressor to run without compressed air. See specific instructions for diesel driven units

Section 3

3.0 Installation

3.1 Inspection

The compressor should be inspected and checked for the following:

1.

2.

Damage during shipping, handling etc.

Check the compressor nameplate to verify the equipment conforms the working parameters.

3.

4.

Check the electrical motor nameplate to match the available power and electrical supply.

Check if the machine is filled with oil or supplied dry.

3.2 Location

The location where the compressor is installed determines to a considerable extent the overall performance and service life of the unit. The compressor should be located in an area that will be dry and sheltered, well ventilated, not exposed to high ambient temperatures, air borne contaminants such as dust, fumes, lint, vapor, steam, gases, engine exhaust and other contaminants. Install the compressor with a minimum of 600-mm

(24”) clearance between adjacent surfaces, to insure adequate cooling and access for service.

Install the compressor on a level surface of sufficient strength to support the static weight of the equipment, as well as the dynamic forces resulting form its operation (preferably a 6” [150 mm] concrete floor). There is no need to bolt the vibration mounts down, except if there is more than a slight vibration. Use shims to level and than tighten the bolts. Do not exert force bolting the subbase down, as this will created unwanted stresses in the structure of the subbase ass’y. Use shims to take the gaps between the feet and the concrete foundation. The canopy doesn’t need t o be bolted down

3.3 Piping

Inlet Piping: If it is necessary to carry the inlet air filter to a clean location, due to excessive dirt, heat, dampness, or toxic fumes in the near vicinity of the compressor, use 1¼” diameter good quality flexible hose; the distance from the compressor should not exceed 3 meters (10 ft). If the inlet filter will be outdoors, protect it with a proper hood against moisture.

Discharge Piping: If piping is required between the compressor package and the filling station, properly selected stainless stell pipes must be used. The piping should be installed in full compliance with all Federal,

State and local codes, standards and regulations. If required, consult the manufacturer for details.

Drain Line Piping: The drain valves inside the compressor assembly are piped to a manifold, which has a port in the bottom – rear- section of the canopy (on the side of the belts). This port must be piped with a next larger size pipe to an area where the condensate can be collected and disposed off according to local codes and regulations. Make sure this pipe is as short and as striaght possible as it is. Make sure the end of this pipe is firmly secured to avoid whipping during the venting cycle.

3.4 Electrical check

Important!

Al though all electrical instructions addressed to the reader directly, the actual inspection, wiring, installation, maintenance, repair etc. must be carried out by licensed and certified electricians .

Make electrical connections to the compressor in accordance with the wiring diagrams and in full compliance with all applicable Federal, State and Local standards, codes and regulations, including those dealing with the grounding requirements. A few electrical checks should be made to insure that the first start up will be trouble free. Make the following checks before attempting any start up

1.

2.

3.

4.

Check the line voltage. Verify that the compressor motor corresponds to mains specifications.

Check the starter and overload for conformity with the motor power and current data.

Check all electrical connections for tightness, including those in the electrical panel of the compressor.

At start up, check the direction of rotation to insure flywheel rotating in the direction of the arrow on it. Although a few minutes of operation in the wrong direction of rotation will not damage the compressor, but running it this way in normal operation will create serious damage as the cooling air flow will be reversed, preventing the compressor cylinders to be cooled during operation.

3.5 Wiring

It is important to select the right size wire and fuses. Install an isolation switch on the wall where the mains line is carried to, with magnetic protection and a capacity three times greater than the motor full load current. Use the same size wire between this unit and the compressor electrical panel. Here are the proper wire sizes to be used on compressors from 10 to 20 HP:

3.6 Sheaves and V-belt alignment check

The W4 Series compressors are supplied with a self tightening rotary slide; therefore these are no adjustments need to be made. However it is a good practice to check at the initial start up the driver sheave and the compressor flywheel for parallel alignment of the V grooves. Check the V-belt tension. Proper tension should be adjusted to give about 13 mm ( ½ ”) deflection with a 1 kg (2 pnds) weight applied at the center of each belt. Check the condition of the belts periodically (see the maintenance table for details.

1.

Make sure you have read this manual carefully, and you understand it. If any questions, call the nearest ALKIN distributor, service or factory.

2.

3.

4.

5.

Be sure all the preparations described in the installation section of this manual have been made.

Check the oil level in the crankcase.

Check the pressure switch and make sure that the dials are set to the proper pressure settings.

Rotate the compressor flywheel several times by hand to see that the compressor is free and in

6.

7.

working order.

Remove all objects such as tools, rugs, etc. from the vicinity of the compressor.

Jog the compressor to check the direction of rotation. Rotation must be in the direction of the arrow on the compressor crankcase and flywheel.

8.

9.

Press the start button to start the machine.

Check for possible leaks in the piping.

10.

Close the filling valves on the filling panel and allows the pressure to rise to the set point.

11.

Make sure that the compressor stops at the set pressure.

12.

Allow the compressor warm up

13.

Open the filling valves and allows the air into the cylinders to be filled.

14.

Observe the stage pressures and make sure it is within the limits shown in stage pressures table. Any deviation from these limits will indicate a mulfunction.

15.

After the first 200 hours of operation, shut the compressor off, drain the oil from its crankcase while oil is hot. Fill the crankcase with recommended oil.

16.

FILL IN THE comissioning report and return a copy to the manufacturer for track record.

4.2 Oil recommendation

The oil level should be checked daily. Top up to the overfill point when required.

On all W4 Series Compressors use the following oils only:

Anderol 750-Anderol 755-Chemlube 751

• Do not use another type of oil without prior written approval of the manufacturer.

• Do not mix oils.

• If you will have to change the type of oil to another approved oil, remove the crankcase cover and clean thoroughly the inner surfaces of the compressor crankcase. Make sure there will be no lint left inside after the cleaning.

22

W 4 S E R I E S

H I G H P R E S S U R E B R E A T H I N G A I R C O M P R E S S O R

• We strongly recommend to replace it every 500 hours for safety. When replacing the oil, remove the crankcase cover and clean inside the crankcase with a clean cloth. Do not use kerosene or gasoline to flush the crankcase.

While doing that, pay attention not to damage the oil level switch extending into the crankcase.

Extreme Cold Operating Conditions:

Operating conditions at below freezing temperatures must be reported to the manufacturer for taking necessary measures to avoid damage. Generally a crankcase heater is fitted to prevent the effect of cold ambient temperatures.

Motor Lubrication :

Most TEFC motors are supplied with greased and sealed breaings which do not need maintenance. Motors with greasing nipples indicate that it needs to periodically be greased. In that case you will find a specific instruction booklet inside this manual which will refer to all maintenance works regarding the electric motor. Follow the instructions in this manual.

4.3 Adjustment

4.3.1 Pressure Swtich Adjustment

You can adjust PH1 pressure switch to the required upper pressure (working pressure) by turning the screw on the pressure switch clockwise or anti-clockwise. Turn the screw clockwise to increase the upper pressure. In this case you may also need to change the safety valve as it is set to open when it reaches the upper pressure. Turn the screw anticlockwise to decrease the upper pressure. Compressor is already set in the factory upon the customers working pressure needs. You can adjust the working pressure if you need a higher or lower working pressure than the factory settings. Compressor will stop when it reaches the adjusted upper pressure.

Standard Pressure Switches used on Alkin Automatic Start/Stop controlled W4 units have standard differential of

20 Bar. In other words lower pressure is set automatically at 20 Bar below the upper pressure limit which is set.

Compressor will restart when the final pressure decreases to a pressure 20 Bar below the upper pressure.

CAUTION

You also have to change the safety valves on the compressor in case you change the working pressure of the.

4.3.2 Sequential Drain Timer Adjustment

These are the drain timers on which the draining times and duration adjustments are made for automatic drain function. On this timers you will find two dials to make the time adjustments.

Upwards dial controls the duration of the automatic drain which the drain valve remains open

(drains the condensate) It is adjustable between 0 to 10 seconds. The dial does not have figures

23

W 4 S E R I E S

H I G H P R E S S U R E B R E A T H I N G A I R C O M P R E S S O R showing the times on it; it needs to be proportionally adjusted. The full scale shows 10 seconds while half of the scale indicates 5 seconds. The downwards dial is used to adjust the time period of the automatic drain during which the drain valve will remain closed. Draining time periods and duration are adjusted as 6 seconds for every 7 minutes.

Factory settings should not be changed for trouble free operation.

4.3.3 Safety Valve Adjustment

Safety valves are set slightly above the normal working pressure of the stage they protect. The normal stage pressures are shown in the following table:

Stage Pressures

Discharge Pressure

275 Bars (4000 psi )

345 Bars (5000 Psi)

5,3 - 6 76 – 87 16,5-17,9 240 – 260 64 - 71 940 – 1040

• Do not adjust the safety valves and do not alter their original settings. Only authorized service technicians are certified to make such adjustments. If required, replace and return the old one for reconditioning to the factory or to a dealer nearest you.

• Do not remove the leaking safety valves and do not replace it with a plug. This may be extremely dangerous. If safety valve leaking, replace it.

Fill in the following forms (total 2 pages) at the initial start up. Send a copy to the manufacturer for record keeping, and retain the original report n the file of your compressor.

W 4 S E R I E S

H I G H P R E S S U R E B R E A T H I N G A I R C O M P R E S S O R

6.

1.

Loosen the valve acorn nut as shown in Figure; then take out the air head cap screws and remove the air head assembly from the cylinder.

2.

Remove the valve assembly from the covers. To disassemble the valve assembly, use a plate with two pins that will fit the holes in the valve seat

(position #3); clamp this plate firmly in a vice and remove the nut (#10) and beleville washer (#9). Note the manner in which the valve parts are assembled in order to replace them in the same order and position after cleaning or installing new parts.

3.

The valve parts can be cleaned by light scraping or stiff brushing (do not use a wire brush!). If necessary, use a non-flammable safety solvent to loosen dirt, oil or carbon deposits.

4.

Discard the worn, scrateched or broken valve discs and springs. Reassemble the cleaned (or replaced) valve parts in their place in the reverse sequence of dismantling and in proper position as shown in the above illustration and in the parts manual. Make absolutely sure that the stop plate is centred properly on its guide; otherwise, the valve will be damaged when it is pulled up tight in the airhead. Replace the beleville washer on the valve bolt and tighten the nuts to the torque values recommended.

5.

Before replacing the valve in the air head (the two halves of the top cover), scrape the old shellac off the valve bolt steel washer and coat it with new shellac to prevent air from leaking under the washer. Replace the acorn nut and tighten it to the lower limit of the torque value, recommended. Do not over tighten this nut, since this will distort the springs and plates, causing the valve to leak. After the valve has been replaced in the airhead. Make certain that the valve operates freely by lifting at its edges with a knife blade.

Replace the cover gasket between the two cover valves, and between the head and the cylinders; then replace the air head asembly. Tighten the air head cap screws to the torque values recommended.

IMPORTANT!

Handle the valve parts with care. Do not nick, scratch or bend them.

32

5.11.5 Servicing 3 rd &4 th stage valve

The 3 rd and 4 th stage valves are plate type valves, made of stainless steel for longer service life and relaible operation. These stages are under particular stress caused by temperatures and high-pressure rates. They should be periodically checked and maintained as inst ructed in the Maintenance Table. Refer to illustration on figüre.

To disassemble the remove the 3 rd or 4 th stage valves, observe the following step by step procedures:

1.

Remove the airhead from the cylinder and pull the valve out of the head. If the valve assembly is covered with hard carbon, soak the valve in a suitable carbon solvent overnight to permit easier disassembly.

W 4 S E R I E S

H I G H P R E S S U R E B R E A T H I N G A I R C O M P R E S S O R

2.

Remove the snap ring (#22 & 32) from the valve by prying under its tapered edge with a penknife.

Withdraw the internal parts of the valve and place them on a clean surface in the correct relationship so that the valve can be properly reassembled.

3.

After disassembly, inspect the condition of all the parts. If theres are no signs of wear, clean the parts or replace them with new original.

4.

To clean the valve parts use a light brush to brush and scrape. When cleaning valve parts use extreme care to prevent damaging the parts.

Use new o-rings and gaskets. When reassembling the valve, make sure all parts are replaced exactly as removed and t hat new gaskets and “O” rings are used. Figure 14 illustrates the relationship of these parts. It is important to install original Alkin “O” rings as these are made of special high temperature resistant material and ordinary o-rings will be promptly damaged causing failures

5.11.6 Piston ring replacement

The high-pressure stage rings (4th and 3rd) wear faster than the other stages. You may need to replace the 4th stage piston rings earlier than the other stages. If this will be the case, it is recommended that all piston rings on a specific piston be replaced at the same time. To remove and replace rings observe the following procedure:

1.

To replace piston rings on the 1st or 2nd stage double-ended piston, both the cylinder and piston are to be removed from the compressor.

2.

3.

To replace piston rings on the 3 rd stage steeple piston and the 4th stage split type piston, only the compression cylinder need be removed. Remove the cylinders in the manner outlined in “ Cylinder replacement ” section.

Remove the old piston rings off the 1st and 2nd stage double-ended piston.

Remove the rings from the 3rd stage piston in the same manner as on the 2st and 2nd stages.

Remove the rings on the 4th stage steeple piston by driving out the dowel pin and unscrewing the piston top. The rings and spacers may then be pulled off the center bolt.

With the rings removed, thoroughly clean the pistons by brushing or scraping lightly. Pay particular attention to cleaning the piston ring grooves, oil return holes and gasket seating surfaces on the cylinderI

Inspect the cylinder bore for scoring or scuffing. If the cylinder bore shows signs of being scored or worn (as indicated by a visible ridging at the end of ring travel.) it must be replaced to establish effective oil control.

Inspect the piston for signs of excessive scoring or cracking. Particularly check the condition of the ring grooves for wear on the sides of the ring lands. If any of these conditions are observed, the piston(s) should be replaced.

To replace the rings of the 1 st and 2 nd stage double-ended piston, or 3 rd stage steeple piston, lubricate the ring grooves and replace the rings with a piston ring expander to avoid breakage and distortion. Pay particular attention to install the rings with the marks facing the appropriate direction into the proper groves, as indicated in the following drawing.

9.

34

Work from bottom compression ring up on the top end of the piston and from the compression ring down on the lower end. Observe this drawing to see the manner, which the tapers are to be positioned.

The word “top”, a white dot or similar marking must face the compression chamber. Caution then must

H I G H P R E S S U R E B R E A T H I N G A I R C O M P R E S S O R be exercised in placement of the rings labeled on the second stage piston. The three bottoms rings on the leftmost figure shows the 2nd stage compression rings, which will have its “top” mark facing the crankcase. On the second figure from left, the ring marking will face away from the crankcase.

The oil rings on the first and second stages are four piece oil wiper rings with an expanderseparator and two steel rails. See second figure from left (above). Place the expander and make certain that these ends do not overlap accidently when installing the other ring segments. Next, install one of the steel rails in the bottom of the groove; this will hold the expander in place.

Now install the separator on top of the steel rails and over the expander. Make certain the butt ends of the expander and the end gap of the separ ator are 180º apart. The second steel rail may now be installed in the top of the ring groove over the separator. With all rings installed, stagger the end gaps

10.

To replace the rings of the 4th stage piston, first examine the spacers and make certain they are not worn or damaged. Next, insert the spacers and rings on the center bolt in the sequence shown in Figure on page 30. The small diameter groove spacers are inserted on the center bolt inside the piston rings. With all rings and spacers in place, return the center bolt to the piston; tighten it and replace the dowel pin.

After the center bolt has been tightened, check to make certain that each ring has a slight freedom of movement (as opposed to extreme rigidity, which may occur if the rings are pinched by the spacers).

11.

When new piston rings are to be installed in the original cylinder of the 1 st or 2 nd stage, the cylinder bore must be “deglazed” to provide a proper seating surface for the rings. Use a #80 grit abrasive cloth and go over the cylinder bore using a rotating, reciprocating motion. Do not overdo “deglazing”; dulling the glaze is usually sufficient and can be accomplished with light pressure.

W 4 S E R I E S

H I G H P R E S S U R E B R E A T H I N G A I R C O M P R E S S O R

Caution!

Do not attempt to deglaze the cylinder bore with a harsh abrasive agent. The use of such abrasive agents usually results in oil carryover and faulty compressor.

After deglazing, the cylinder walls should be thoroughly cleaned by scrubbing the bore with a stiff bristle (do not use wire brushes); brush using ordinary soap or a detergent and hot water. Rinse thoroughly with hot water and then check the cleanliness of the cylinder bore by wiping it with a soft white cloth.

12.

The cylinders may now be replaced. Replace the cylinders in the manner outlined under “ cylinder removal & replacement ”.

13.

After the new piston rings have been installed, the compressor should be operated for at least 10 hours at full load before checking for proper air delivery or oil consumption.

5.11.7 Crankshaft bearing replacement

Do not replace the crankshaft bearings unless you are equipped and trained to do so. In case of bearing failure, we recommend to install a new crankshaft assembly (complete with bearings).

INSTALLING THE CRANKSHAFT ASSEMBLY:

A new crankshaft assembly includes the crankshaft itself, the two ball bearings, spacers, and a woodroof key, all installed as a complete assembly. To remove the old crankshaft and install the new one proceed as outlined in the following:

First, drain the oil from the frame. Then remove the beltwheel key and shaft end cover.

1.

2.

Disconnect the tubing to the pilot valve and remove the crankcase cover together with the pilot valve as a unit. Next, take the centrifugal unloader assembly off the end of the crankshaft.

Remove the cylinders as explained in section cylinder removal & replacement.

3.

4.

5.

6.

7.

8.

9.

Remove the connecting rods from the crankshaft pin section.

Pry off the snap ring from the outer bearing (on the flywheel side).

The crankshaft assembly is a moderate press fit in the crankcase and may be forced out by tapping the flywheel end of the shaft with a lead hammer.

Prepare the new crankshaft assembly for installation by removing the snap ring from the outer bearing.

The new crankshaft may be inserted into the crankcase from the cover side. Since the assembly is a moderate press fit it may be forced into position by tapping it with a lead hammer; pay attention to strike the center of the shaft, since an off center blow may cause damage.

The crankshaft assembly must be pushed in until the outer bearing clears the end of the frame by about

1/16”(1.56 m). Replace the snap ring by putting one end in the groove and springing it into place.

Tap the crankshaft back until the snap ring is tight against the frame.

10.

Before replacing the shaft end cover make certain that there are no burrs on the beltwheel end of the crankshaft and that the edges of the keyway are smooth and slightly rounded to prevent damage to the oil seal. When satisfied that the crankshaft is smooth, replace the shaft end cover. As an added precaution against damaging the oil seal, use a piece of.003” (.076 mm) brass shim of necessary size and form it into a cone. Lubricate the surface of the cone; position it on the shaft as shown in Figure 3-7 and slide the cover and seal over the cone and into position against the frame.

11.

Replace the pistons and cylinders as outlined “ cylinder removal & replacement ”.

12.

Replace the centrifugal unloader assembly and crankcase cover. Reconnect all tubing.

13.

Replace the flywheel. Replace the belts.

14.

Fill the crankcase with recommended oil to the overflow point of the filler hole.

5.11.8 Oil seal replacement

To replace the oil seal, proceed as follows:

1.

Remove the belts, flywheel and the woodroof key and seal cover.

2.

3.

The oil seal may be removed from the cover by prying under the inside lip with a pinch bar or driving it out with a metal rod.

Insert the new seal with the sealing lip facing in the same direction as the one removed and coat the

4.

outside diameter of the seal with shellac or pipe compound. Press the seal into the shaft end cover with a padded vise.

After the seal has been installed in the shaft end cover, the cover should be returned to its original location on the frame by sliding it over the end of the crankshaft. To avoid damaging the seal lip, make sure that the surface of the crankshaft is free of burrs and sharp edges. As a precaution to prevent cutting the seal, use a piece of .00

3” (.76 mm) brass shim stock of adequate size and form it into a cone.

Lubricate the surface of the cone; position it on the shaft as shown and slide the cover and seal over the cone and into position against the frame.

5.

Replace the key and flywheel and the belts.

5.11.9

Piston&piston pin removal and replacement

1.

2.

To remove a piston from the connecting rod, first remove the piston and rod from the compressor as outlined under “ cylinder removal & replacement ” on thi s page.

With the piston and connecting rod removed from the compressor, remove the lock rings at the ends of the piston pin. With a dowel of appropriate size and a soft hammer drive out the pin. To prevent distorting the piston during this operation, inserting fork-type shims of the necessary thickness between the rod and the boss must eliminate the play between the piston pin boss and the connecting rod.

3.

4.

To install the new pin, align the connecting rod between the bosses inside the piston, and insert the same number of shims between the boss and rod that were used when the pin was driven out.

Lubricate the pin and drive it into the piston and through the connecting rod with an appropriate dowel and a soft hammer. When the pin is in place, snap the lock ring back in their grooves.

5.

To replace the assembled piston and rod in the compressor, follow the instructions given under Cylinder

& piston removal & replacement in the following section.

5.11.10 Cylinder&piston removal and replacement

To Remove Cylinders and Pistons Proceed as follows:

method to prevent damage to the rings when inserting, and push the piston into the cylinder as far as possible. Next, replace the crankcase-to-cylinder gasket, after which, the cylinder, piston and connecting rod may be replaced as a unit by inserting the connecting rod (with its oil dipper pointing down) into the crankcase. Slip the end of the connecting rod over the crankshaft pin and bolt the cylinder to the frame.

Next, replace the gasket between the 1st and 2nd stage cylinders. Lubricate the piston rings and slide the

1st stage cylinder over the piston using an appropriate piston ring compressor method to prevent damage to the rings. With the 1st stage cylinder replaced, bolt it to the 2nd stage cylinder. If the airheads have been removed from the cylinders they must be replaced according to the procedure outlined under “ air head replacement ”

To replace the 3 rd &4 th stage pistons lubricate the bore of the crosshead cylinder and insert the connecting rod and piston into it. Next replace the cylinder to frame gasket, after which the cylinder, piston and connecting rod may be replaced as a unit by inserting the connecting rod (with its oil dipper pointing

down) into the crankcase and slipping the end of it over the crank pin. With this done bolt the cylinder to the crankcase. Next, replace the gasket between the crosshead and compression cylinder. Lubricate the piston rings and slide the compression cylinder over the piston using an appropriate piston ring compressor method to prevent damage to the rings. With the compression cylinder replaced, bolt it to the crosshead cylinder. If the airhead was removed, it is essential that it be replaced in the manner described under “ air head replacement ”

Replace the centrifugal unloader assembly to the end of the crankshaft.

Replace the crankcase cover and all tubing and fittings that were removed.

10.

Fill the crankcase to the overflow point with UL751 oil

5.11.11 Air head replacement

The attaching screws for all airheads are to be tightened evenly and in rotation to the torque value given in the torque values table. To avoid faulty valve operation, the 3 rd and 4 th stage air head attaching screws must be tightened as closely as possible to the torque values given, and a feeler gauge is to be used between the air head and cylinder to make certain the air head is drawn down evenly.

5.11.12 Precautions for storing

Whenever the compressor is taken out of service the following precautions must be taken to prevent general deterioration.

1.

2.

3.

Drain the oil from the frame. To prevent rusting, all interior surfaces of the unit must be treated with a rust inhibiting oil. To treat all interior surfaces properly, remove the air heads from all cylinders, and fog or pour a small amount of rust inhibiting oil directly into the cylinder. Remove and clean the valves as outlined in section “ servicing valves ” and treat the valves and heads wit h rust inhibiting oil. Reassemble the valves in the air head and replace the heads on the cylinders according to the instructions given under

“ airhead replacement and torque values. Fill the frame with a suitable rust inhibiting oil, and operate the machine for about 10 minutes. Leave the rust inhibiting oil in the frame until the compressor is put back in service.

Relieve tension from the V-belts by lifting the electric motor underneath the compressor unit, and placing under a proper size wood block.

Remove the intake air filter assembly.

W 4 S E R I E S

H I G H P R E S S U R E B R E A T H I N G A I R C O M P R E S S O R

4.

5.

Plug all openings to prevent moisture from entering the unit.

Store the unit in a dry, sheltered location.

6.

Drain all condensate from the air storage bot tles. Follow the manufacturer’s instructions for storing the electric motor, gasoline engine or any system that may be used in conjunction with the compressor.

5.11.13 Intercoolers and aftercooler

A set of tubes acting as heat exchangers are installed between each stage (intercoolers) and after the last stage

(aftercooler ). A moisture trap is installed after the 2nd and 3rd stage intercoolers and downstream the aftercooler. As the compressed air is cooled in these tubes, the water vapors condensate; the moisture traps cause the water in liquid state to collect in the bottom section of the trap, from where it is preiodically removed through externally mounted automatic drain valves.

Servicing the Cooler Tubes:

Clean the surface of the tubes periodically; see “ Maintenance Table ” for recommended cleaning intervals.

5.11.14 Automatic drain valves

The automatic drain valves are simple, yet reliable draining devices, controlled with low-pressure air taken from the second stage moisture trap. A Normally Closed 3 way low pressure solenoid valve sends the control air to close the drain valves, and removes the control air to open them. A sequential timer in the control cabinet controls the opening intervals and the time opened. See also the section under “Drain Timer”.

5.11.15

Filtration equipment

Prefilter:

The prefilter housing is made of stainless steel and it contains a disposable filter cartridge. Replace this cartridge every 250 hours. At the first replacement, inspect its condition and if excessive dirt is observed, reduce the replacement interval to 200 hours. If necessary, clean the housing as well. Use a clean lint free cloth to clean. Make sure not to leave any parts or rugs inside the housing, which may block the air passages in the caps.

Purifier:

The purifier housing as well is made of stainless steel and it contains in it a refillable cartridge. Follow the refilling instruction that is supplied with the refilling kits for this procedure. The procedure to remove and replace a purifier cartridge is as follows:
