Fault Diagnosis of Reciprocating Compressor Using Pressure Pulsations
نویسندگان
چکیده
The major problems encountered in a reciprocating compressor are because of the valve failure .The other problem of leakage past the piston because of the worn out piston rings has also been placed in the reciprocating compressor. Pressure pulsations generated inside the piping of a reciprocating compressor may be taken as one of the tool for diagnosing the nature of fault inside the compressor. In this paper the common type of faults are simulated in the complete thermodynamics process of a healthy reciprocating compressor. The fault like discharge valves and leakage past piston rings have been considered for formulation. . The change in nature of pressure pulsation can be used for condition monitoring of reciprocating compressor.
