| 摘 要： | 利用动量矩定理,建立了叶轮盖板中流体旋转角速度的一阶微分方程,得到了计算离心泵泄漏量的方法.为了获得泄漏量,需要进行迭代求解.从该微分方程出发,可得到容积效率、轴向力等参数.试验研究表明,用此公式计算的理论泄漏量和试验值之间的相对误差在7%～10%以内,验证了该方法的合理性和正确性.

| Abstract: | This paper describes a method to calculate the leakage rate in a centrifugal pump. The method solves the non-linear first order differential equation for the angular velocity of the fluid in the impeller shroud. This parameter is necessary to determine the performance of a centrifugal pump according to a prediction procedure. From the calculation of this leakage rate, the volumetric efficiency and the axial force can be obtained. The result shows that the theoretical leakage is in agreement with experimental result within 7%-10%. It also shows that this method is reasonable and reliable. |
