Summary:

This paper presents a hydraulic pump fault diagnosis method based on a discharge pressure pulsation model. This diagnosis method was based on the pressure signals measured at the discharge port of the pump. The obtained signals were transformed into frequency domain for performing wavelet analysis to separate the fault signals from the pressure signal at the time a fault occurs. This method was first evaluated via simulation analysis, and then validated against test data. Results showed that this wavelet based fault diagnosis method was capable of detecting pump failure using the outlet pressure pulsating signal
