摘要

回顾了离心泵噪声研究的国内外现状。首先总结了离心泵噪声的来源,并对离心泵噪声来源的研究进行分类评述:机械结构影响离心泵噪声的研究,包括蜗壳几何形状与叶轮影响离心泵噪声的研究;流体动力影响离心泵噪声的研究,包括对汽蚀、流固耦合与湍流诱发噪声的研究。而后从离心泵诱发噪声的数学模型推导、数值计算与试验研究三个方面对研究离心泵噪声所使用的方法进行了总结;最后讨论了目前研究存在的一些问题和今后的研究方向。

Abstract

Researches on noise of centrifugal pump are reviewed. Firstly, noise sources of centrifugal pump are summed up. And researches on noise sources of centrifugal pump are also classified by noise from mechanism, including volute with different geometry shapes and impeller, and by noise from hydrodynamics, including cavitation, fluid-structure interaction and turbulence. Then methods used in these researches are summarized by three aspects, namely theoretical deduction of simplified model, numerical model by PC and experiment. At last, some opening issues at present and new fields in future in the researches of noise of centrifugal pump are putted forward.
