Discussion about Pulsation of Stator Radial Force in Variable Flow Vane-type Pump

对变量叶片泵定子所受径向液压力进行分析 ,其大小和方向是不断变化的 .该力可以造成对定子的冲击和振荡 ,引起叶片泵的压力、流量脉动 ,产生振动、噪声 .将园柱弹簧改为园锥弹簧。

The radial hydraulic force of stator in variable flow vane-type pump is discussed,whose numerical value and direction are continually changeable. This pulsatile force would lead to collision and oscillation to stator,pressure and flow pulsation to pump,and engender vibration and noise. There are two kinds of measures feasibly to remove these disadvantages:ont is to that change cylinder spring into a cone one,and the other is to put a rubber gasket between stator and spring.
