- Abstract
In this paper an acoustic emission based cavitation fault detection system is proposed for a centrifugal pump. The monitoring is performed tracking a fault indicator obtained using the RMS value of the acoustic emission signal in time domain and the RMS value of the coefficients obtained by applying discrete wavelet transform on the acoustic signal using db6 mother wavelet. Experiments in different cavitation levels and under different operation conditions are carried out in a 1/2 hp centrifugal pump dedicated test bed. Results showed that the proposed fault indicators are suitable for detecting and evaluating cavitation severities in a centrifugal pump.
