How does the compressor lubrication system differ for reciprocating and centrifugal compressors?
Difference in lubrication system of reciprocating and centrifugal compressor.
Answer to Problem 1RQ
Difference in lubrication system of reciprocating and centrifugal compressors has explained below.
Explanation of Solution
Compressor is a device which is used to compress the fluid.
Lubrication is required to reduce the heat and friction.
The centrifugal compressor consists of a separate pump, filter, cooler, oil lines and oil reservoir. The lubrication oil pumped from the reservoir to the various parts of the engine.
The reciprocating compressor consists of a small pump system which is driven by compressor crankshaft.
In reciprocating compressor, the lubricating oil pump is driven by compressor shaft whereas in centrifugal compressor, the oil pump is driven by separate motor.
Reciprocating compressor does not have separate sump for the oil, but centrifugal compressor has separate oil sump.
