AIR FLOW IN THE
COMPRESSOR SYSTEM
Figure 4- 8 page 52 - Air enters the air filter and passes through the inlet unloader valve and on into the
compression chamber where oil is injected into the air. After compression, the air/oil mixture passes into
the oil reservoir where most of the entrained oil is removed by velocity change and impingement and
drops back into the reservoir. The air and remaining oil then passes through the air/oil separator. The air
then passes through the minimum pressure/check valve, the after cooler and the moisture separator and
into the plant air lines
.
LUBRICATION, COOLING AND SEALING
- Oil is forced by air pressure from the oil reservoir through
the oil cooler, thermostatic mixing valve, and oil filter and discharge into the compressor main oil gallery.
A portion of the oil is directed through internal passages to the bearings and shaft oil seal. The balance
of the oil is injected directly into the compression chamber to remove heat of compression, seal internal
clearances and lubricate the rotors.
