离心泵的轴向力计算公式及叶轮背叶片的设计方法

A Formula for determination of Axial Force and a Design Method of Back Blade in Centrifugal Pump

本文根椐离心泵轴向力产生的原因,结合流体力学基本方程推导出一种新的计算轴向力的公式,并提出了叶轮背叶片的设计方法。

Based on the analysis of origion of axial force and basic equations of fluid mechanics, a new formula for determination of axial force and a design method of back blades in a centrifugal pump is presented in this paper.
