STARTING UNLOADING SYSTEM (MODEL 2000)

The purpose of the system is to relieve cylinder pressure when the unit stops, permitting it to start against a light load. A light load increases the life of the driver and belts and also reduces the possibility of tripping the overload relay. The system operates in the following manner:

The centrifugal unloader is attached to the end of the crankshaft as shown in the following illustrations.

When the unit starts, centrifugal force acts upon the unloader weights and they swing outward. This permits the plunger and thrust pin to move inward and the pilot valve to close. The escape path to atmosphere for the cylinder pressure is now closed and the compressor pumps air in a normal manner.

When the unit stops, the weights retract, permitting the thrust pin spring to move the plunger and thrust pin outward. The thrust pin opens the pilot valve and the trapped air pressure escapes from the cylinder and intercooler through a passage in the frame end cover, through the unloader tube and to atmosphere through the inlet filter/silencer.

STARTING UNLOADING SYSTEM (2000P)

Pressure lubricated compressors use a hydraulic unloader system to provide loadless starting. This system has the added feature of providing emergency unloading should oil pressure be lost during compressor operation.

The hydraulic unloader circuit bypasses the auxiliary valve (H) to direct control air to the head unloaders when oil pressure is lost. This circuit is controlled by the hydraulic unloader valve (E), a normally

open valve that closes on rising oil pressure. During compressor operation, the oil pressure holds the hydraulic unloader valve closed. Head unloader actuation is controlled by the auxiliary valve.

When oil pressure is lost, either due to compressor shutdown or to a lubrication problem during compressor operation, the hydraulic unloader opens, actuating the head unloaders (F). This action will either vent the shut down compressor in preparation for the next start-up or release compression load to minimize damage if oil pressure is lost while the compressor is running.

PILOT VALVE ADJUSTMENT

If the pilot valve tube line is excessively hot, it is a good indication that the pilot valve is leaking and adjustment is required.

To adjust the pilot valve, proceed as follows:

1.Stop the unit and disconnect and tag the electrical supply main switch to prevent accidental start-up.

2.Remove the pilot valve tube and the tube fittings.

3.Remove the pilot valve body and all existing shims.

4.Screw the pilot valve body back into the frame end cover (without any shims) until contact with the thrust pin is felt. Advance the pilot valve body 1/4 to 1/2 turn more.

If contact with the thrust pin cannot be felt, the following steps may be necessary to locate the contact point:

1.Insert a small instrument (punch, rod, nail, etc.) into the end of the pilot valve until it contacts the valve stem.

2.While still inserted in the pilot valve, make a mark on the instrument even with the outside edge of the pilot valve body.

3.Keeping the instrument pressed lightly against the valve stem, screw the pilot valve body into the frame end cover. When the mark on the instrument starts moving out away from the edge of the pilot valve body, contact has been made with the thrust pin.

4.Advance the pilot valve body 1/4 to 1/2 turn more and proceed with step five.

5.Measure the gap between the pilot valve body and the frame end cover.

6.Remove the pilot valve body and add enough shims to fill the gap measured in step five.

7.Screw the pilot valve body back into the frame end cover until the body is tight on the shims.

8.Reconnect the pilot valve tube and tube fittings.
