Reciprocating Compressor Lubrication System

The first is a recirculating system which protects bearings bushings thrust plates and crossheads in the drivetrain.

Reciprocating compressor lubrication system.

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 frame lubrication system circulates oil to the frame bearings connecting rod bearings crosshead shoes and can also supply oil to the packing and cylinder lubrication system. In addition reciprocating compressors are used for high pressure gas reinjection into downhole reservoirs to enhance crude oil recovery. 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.

Reciprocating compressors frame lubrication system. 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. Centrifugal compressors not discussed here are typically used on natural gas pipeline systems to move large volumes of gas at lower pressures. Wet gas compressors tend to be centrifugal types.

Reciprocating compressors rely upon two lubrication systems that deliver oil to critical components in the drivetrain cylinders and packings. Splash lubrication systems are the least expensive and are used in small air compressors. Therefore small plunger pump force feed lubricators systerns are used. The major factors involved in the selection of compressor lubricants include.
