Reciprocating Compressor Lubrication System

Compressor crankcase lubrication is relatively simple.

Reciprocating compressor lubrication system.

In addition reciprocating compressors are used for high pressure gas reinjection into downhole reservoirs to enhance crude oil recovery. Reciprocating compressors rely upon two lubrication systems that deliver oil to critical components in the drivetrain cylinders and packings. Centrifugal compressors not discussed here are typically used on natural gas pipeline systems to move large volumes of gas at lower pressures. Reciprocating compressors cylinder packing lubrication system the flow required to lubricate the packing and cylinders is quite small and the pressure necessary to inject the lubricant at these locations is quite high.

Typically positive displacement compressors reciprocating designs in particular produce higher pressures while dynamic compressors such as centrifugal and axial designs are able to move greater gas volumes. The first is a recirculating system which protects bearings bushings thrust plates and crossheads in the drivetrain. Splash lubrication systems are the least expensive and are used in small air compressors. High flow low compression ratio applications are best served by axial flow compressors.

Therefore small plunger pump force feed lubricators systerns are used. Reciprocating compressors are typically used where high compression ratios ratio of discharge to suction pressures are required per stage without high flow rates and the process fluid is relatively dry. The major factors involved in the selection of compressor lubricants include. Wet gas compressors tend to be centrifugal types.
