Abstract
This paper reviews the sources of vibration from a centrifugal pump during normal operation and explains how these sources are excited by other factors, particularly the onset of cavitation. It discusses the efficacy of the vibration method for detecting and diagnostic the cavitation in centrifugal pumps, using spectrum analysis. Finally, the experimental results of using vibration method for monitoring cavitation in centrifugal pumps has been presented and discussed.
