Abstract
Cavitation in the pump induces vibration and noise, which leads to the degradation of pump performance and damage to the impeller. Therefore, it is of great significance to accurately identify the cavitation state of the centrifugal pump. To determine the cavitation state using the vibration characteristic frequency of the centrifugal pump, it is necessary to accurately identify the characteristic frequency due to the noise
