Abstract

Abstract: Based on low frequency fluctuation is an important cavitation-associated phenomenon, mechanisms of cavitation inception and pump outlet pressure are analyzed. The experimental results of power spectra for sea water hydraulic pump show the affection of cavitation and inner leakage on three character parameters. Some criteria are suggested to distinguish the initiation of cavitation from inner leakage.

Key words: Cavitation inception, Hydraulic pump, Internal leakage, Pressure fluctuation, Seawater
