摘要： The present disclosure provides a plunger type water pump, which mainly comprises a cavity body, a rotary main shaft and a plunger flow-distributing unit. The plunger distributing unit comprises a flat valve assembly, a plunger-shoe assembly and a supporting valve assembly; the plunger-shoe assembly divides the cavity body into a high-pressure cavity and a low-pressure cavity independent of each other; the high-pressure cavity is in fluid communication with the flat valve assembly; and the low-pressure cavity is in fluid communication with the supporting valve assembly. According to the present disclosure, the high-pressure water and the low-pressure water are independent of each other. This can ensure a high volumetric efficiency of the water pump under ultra-high-pressure conditions and surely provide the fluid supporting and lubrication for a friction coupling under high-speed heavy-load conditions so as to prolong the service life of the water pump.
摘要翻译：本发明提供一种柱塞式水泵，其主要包括腔体，旋转主轴和柱塞流量分配单元。柱塞分配单元包括平阀组件，柱塞 - 鞋组件和支撑阀组件; 柱塞 - 鞋组件将腔体分为彼此独立的高压腔和低压腔; 高压腔与扁平阀组件流体连通; 并且低压腔与支撑阀组件流体连通。根据本公开，高压水和低压水彼此独立。这可以在超高压条件下确保水泵的高容积效率，并且可以在高速重载条件下为摩擦联接提供流体支撑和润滑，从而延长水泵的使用寿命。
