| Abstract: | A new method of fault feature is proposed by pressure signal in pump cylinder as system feature signals.A diagnosis method based on "frequency-energy-fault identification" pattern recognition diagnosis approach is introduced to the fault detection on pump valves of reciprocating pumps.The improved BP neural network is used to diagnosis various faults of pump valves by the feature vectors constructed above. |

| Keywords: | reciprocating pumps fault diagnosis feature vectors wavelet packet neural network |
