【 摘 要 】

The major problems experienced in reciprocating air compressor are excessive noise in operation and vibration of the compressor. In this paper a reciprocating air compressor is studied and it is monitored to find the mechanical or other faults present in it by performing noise and vibration test. Here vibration signature analysis is done along with measurement of noise harshness level of a reciprocating compressor. After the test the faulty part of the compressor was replaced and same test was performed again. Microscopic analysis of parts of bearings was also done to study and analyze the cause of defects. Here significant improvement is achieved in NVH.
