Where water-cooled refrigeration and air-conditioning systems are not operated in the winter, it is necessary to service them before discontinuing their operation. They should be…
When starting a water-cooled compressor after winter shutdown, the following procedure is suggested: 1. Install a pressure gauge on the condenser, and check for pressure.…
The reinstallation of a compressor is roughly a reversal of the process of removing it. First, place the mounting pads and washers in position. Place…
To remove a compressor from the unit, proceed as follows: 1. Attach a compound gage to the suction-line valve. Close the suction-line shutoff valve and…
The reason for a compressor being stuck-up is usually the result of moisture in the system, or a lack of lubrication. When this occurs, the…
A knock in the compressor may be caused by a loose connecting rod, eccentric strip and rod, eccentric disk, piston pin, crankshaft, or too much…
To determine whether a compressor is leaking at the seal, proceed as follows. Close the shutoff valves by turning the stem clockwise as far as…
In most air-conditioning and refrigeration systems, it is possible to control the refrigerant feed so that liquid refrigerant does not return to the compressor during…
Centrifugal compressors are essentially high-speed machines and best suited for steam-turbine drives. Because they are designed for the same high speed as the turbine, they…
