Condition monitoring of reciprocating compressors

Print

Complexity of reciprocator vibration analysis consists in the cyclicity of operation of moving parts. Vibration signal is almost periodic process, and the wear rate of the unit influences vibration signal level under certain values of crankshaft rotation angle.

However, it is hard to recognize the worn part corresponding to vibration signal change because clearances of different details may cause change in vibration signal value under the same values of crankshaft rotation angle.

The problem concerned can be solved by the following: firstly, 'competent' choice of the number of points for vibration sensors installation; secondly, 'fortunate' location of the sensors on the unit; and thirdly, 'reliable' algorithm for the signal processing. The only criterion for solving of these problems is field experience of the analysis of reciprocating compressor malfunctions at the moment of their repair, and comparison of malfunctions with accumulated data.
