THE USE OF TWO-DIMENSIONAL AUTOCORRELATION OF VIBRATION SIGNAL FOR FAULT DETECTION OF RECIPROCATING COMPRESSORS
ABSTRACT: Reciprocating
compressors are the oldest kind of compressors designed for mass production.
These compressors still become- the best choice for several industrial
application due to their advantages that give high compression ratio and low
mass flow. There are many cases of reciprocating compressors faults, such as
fault in valve, wrist-pin, and crankpin bore on connecting rod. In this paper,
fault detection of such compressors due to exhaust valve and pin bore faults
will be presented based on the vibration signal. At first, time domain and
frequency domain will be the basic method for analysis and then it will be
completed by spectrogram and two-dimensional autocorrelation. The patterns of vibration
signals were analyzed and compared through their vibration signatures.
Vibration signaturescould give informations related to impending faults in the
compressors. Therefore, the fault diagnostics of compressor could be realized.
