[0009] The intelligent centrifugal pump cavitation detector of the present invention will be described in detail below using the accompanying drawings and embodiments
[0010] refer to figure 1 , the intelligent centrifugal pump cavitation detector of the present invention includes a signal acquisition system 2 composed of a pressure transmitter arranged at the pressure taking port at the inlet of the centrifugal pump 1, which is connected with the signal processing system 3, and the signal processing system 3 is connected with the detection system 4. , the detection system 4 is connected with the display control system 5 . The accurate acquisition of the pressure pulsation signal at the inlet of the centrifugal pump 1 by the signal acquisition system 2 is a key link in fault diagnosis. In order to obtain an accurate pressure pulsation waveform and reduce the detection error caused by waveform distortion, the pressure-taking port at the inlet of centrifugal pump 1 must be sma...
