一、前言配流盘是轴向柱塞泵的配流机构,它要承受转子体传来的数值很大而且是周期性变化的轴向载荷,同时又和转子体之间作相对高速滑动。它的设计合理与否,对泵的性能,特别是效率、温升、磨损和寿命,影响很大。目前对配流盘的设计,普通采用的是剩余压紧力设计法。这种方法的实质,是使除配流盘产生的流体静压力平衡掉大部分转子体的轴向载荷(压紧力)外,还使转子体对配流盘存在着一定的剩余压紧力,保持转子体在任何负载下始终紧压在配流盘上,以实现配 I. INTRODUCTION The flow control plate is an axial piston pump with a flow distribution mechanism. It has to bear the large and periodic axial load transmitted by the rotor body, and at the same time make relatively high-speed sliding between the rotor body. Its design is reasonable or not, the performance of the pump, especially the efficiency, temperature rise, wear and life expectancy. The design of the current plate, the common method is to use residual pressure design. The essence of this method is to make the hydrostatic pressure generated by the distribution plate balance out the axial load (pressing force) of most of the rotor bodies and to make the rotor body have a certain residual pressing force on the distribution plate to keep Rotor body under any load always squeeze on the valve plate, in order to achieve with
