| 摘 要： | 离心泵的效率主要由叶轮的水力模型决定,叶轮的圆盘摩擦损失与叶轮外径的5次方成正比,减小叶轮的外径就成为提高泵效率的重要途径之一.文中根据实际使用叶轮的参数,用理论和经验相结合的方法改进原有叶轮叶片的各几何参数,并进行优化组合,同时计算了叶轮出口外径为最小值时叶轮的出口安放角,使叶轮的效率达到最高.

| Abstract: | The efficiency of a centrifugal pump is determined on the Hydraulic Model of impeller,disk friction loss of impeller is proportional to outlet diameter loss of 5-power,and reducing outlet diameter is an important method for improving efficiency of a pump.This paper uses impeller parameters to modify and optimize geometrical parameters of impeller blades,and calculate outlet angles of blade according to literature when outlet diameter of impeller is minimum.This approach maximizes the efficiency of impellers. |
