Abstract
During the normal operation of a large bidirectional axial flow pump,the flow is extremely complex.Affected by factors such as the natural environment and flow rate changes,the flow pattern is easily changed,causing large hydraulic vibrations,and the vibration will also produce huge noise.This paper takes a low-head axial flow pump as the research object,uses numerical simulation and experimental verification,and combines theoretical analysis to study the pressure pulsation law of the axial flow pump under multiple working conditions,providing a basis for engineering design and practical application.关键词
