In addition reciprocating compressors are used for high pressure gas reinjection into downhole reservoirs to enhance crude oil recovery.
Reciprocating compressor lubrication system.
Type size and speed of compressor.
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.
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.
Splash lubrication systems are the least expensive and are used in small air compressors.
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 rely upon two lubrication systems that deliver oil to critical components in the drivetrain cylinders and packings.
High flow low compression ratio applications are best served by axial flow compressors.
Reciprocating compressors frame lubrication system.
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.
The first is a recirculating system which protects bearings bushings thrust plates and crossheads in the drivetrain.
