A Review of Fluid-Induced Excitations in Centrifugal Pumps

This paper describes the related research work in field of fluid-induced vibration centrifugal pumps conducted by many researchers. In recent years, all walks life have put forward higher demands for performance which drives investigation on root cause pump and development guidelines design low-vibration pumps. Fluid-induced excitation is most important significant source vibration. Understanding its generation mechanism dominant characteristics developing methodology. starts with analysis unsteady flow summarizes such as jet–wake structure, secondary flow, rotational stall operating pump. Based understanding structure pump, based pressure pulsation forces are summarized. For at nominal rate, blade passing frequency (BPF) dominates suppression methods classified summarized to provide reference a
