高压大排量径向柱塞泵定子运动规律分析
Analyses on Stator Motion Laws of High Pressure Large Displacement Radial Piston Pump
摘要
Abstract
In order to improve the friction condition of the stator-slipper pair of the high-pressure large displacement radial piston pump and achieve precise pump variables,a non fixed installation structure in the circumferential direction of the stator was proposed.Then the mechanical characteristics of the slippers and piston component were analyzed,the sliding friction torque of a single slipper and the combined force torque of 11 slippers friction were established,and the variation curve of the stator angular velocity was obtained.It was found that the stator can move under the sliding friction torque of slippers,and the friction torque in the oil discharge area is greater than that in the oil suction area.After normal operation of the radial piston pump,the stator angular velocity stabilizes between 89.5 rad/s and 90.6 rad/s,exhibiting periodic changes.The number of slippers that hinder stator movement is 4 or 5 alternating changes.The research provides certain references for the design of slipper pairs for high-pressure large displacement radial piston pump and the improvement of pump performance.关键词
