<strong>The</strong> <strong>Compressor</strong> Lubrication System<br />
Figure B—1 is a schematic illustration of the compressor lubrication system, indicating how the oil<br />
circulates through the system and through standard compressor components. <strong>The</strong> following describes<br />
the principles of normal operation.<br />
Normal Operation<br />
1. <strong>The</strong> main oil pump [B], mounted on the compressor gearbox and driven off of an extension of the<br />
bullgear shaft, draws oil from the reservoir [A], through check valve [N], and cycles it through the<br />
lubrication system and the compressor gearbox. Check valve [C]prevents the oil from being<br />
pumped back into the reservoir through the auxiliary oil pump [M].<br />
2. Excess heat is removed from the oil as it passes through the oil cooler [D]. <strong>The</strong> throttle valve [E] in<br />
the return water line regulates the flow of the cooling water through the oil cooler, thereby<br />
keeping the temperature of the oil within the normal operating range.<br />
3. <strong>The</strong> oil continues on to the oil filter [F] where impurities are removed.<br />

4. In the gearbox [G] the oil flows through a manifold [H] where it is distributed to the bullgear<br />
bearings [I], the pinion bearings [J], and the two gear-mesh spray nozzles [K].<br />
5. <strong>The</strong> oil flows from the gearbox to the oil reservoir, where it passes around a baffle arrangement<br />
that breaks down any foam before it is allowed to continue to recycle through the compressor<br />
lubrication system.<br />
6. <strong>The</strong> pressure regulator valve [L] maintains the correct operating pressure throughout the<br />
lubrication cycle and returns any excess oil to the reservoir.<br />
NOTE: <strong>The</strong> auxiliary pump does not run during normal operation. <strong>The</strong> main oil pump<br />
provides full compressor oil flow and pressure requirements.<br />
