Abstract
This paper reviews the sources of acoustics in a centrifugal pump during normal operation and explains how these sources are affected by other factors, particularly the onset of cavitation. It analyses the efficacy of the acoustics method for detecting cavitation in centrifugal pumps, using spectrum analysis of acoustic signals. Finally, the experimental results of using acoustics method for cavitation detection on the test-rig are presented and discussed.
