In order to establish a useful method to suppress cavitation erosion, especially the 'severe erosion,' i.e., two figures or more severer than ordinary one, and to monitor the erosion, the cavitation noise, the AE noise and the vibrational acceleration are systematically measured by a hydrophone, an acoustic emission AE sensor and an accelerometer in a typical centrifugal pump, in relation to several types of cavitation. The severe erosion is closely related to the highly erosive vortex cavitation and is also monitored by detecting the noise and the acceleration levels corresponded well with the types of cavitation.
