Application of Mathematical Models to Detect and Diagnose Reciprocating Compressor Valve Leakage

This report presents results from the model simulation of the pressure, vibration, and current signatures as derived in the accompanying publication [1] and compares the simulated data with measured data from an actual laboratory motor-compressor system. The simulations from the models were used to determine the information content of the sensor signals, compare the various diagnostic techniques and develop a multisensor approach based on the integration of these techniques to detect and diagnose reciprocating compressor valve leakage.
