摘要: 为解决现有往复柱塞泵流量脉动大，噪音高的问题，本文研究开发了一种阀配流水液压径向柱塞泵，利用AMESim建立了水液压径向柱塞泵的仿真模型，分析了两种不同结构的单向阀配流效果，并针对平板阀结构单向阀做了优化改进。结果表明：合理的吸排液弹簧设计，能够降低柱塞吸液过程中的压力损失，提高泵的吸液效率；柱塞腔吸液负压的产生与弹簧设计、余隙容积相关度不高；余隙容积是影响柱塞泵容积效率的关键参数，较低的余隙容积能够提高吸排液阀芯的响应速度。
Abstract: In order to solve the problems of large flow pulsation and high noise in existing reciprocating piston pumps, this paper studies and develops a type of valve distribution hydraulic radial piston pump. A simulation model of the water hydraulic radial piston pump is established using AMESim, and the flow distribution effects of two different structures of one-way valves are analyzed. Optimization and improvement are made for the flat valve structure one-way valve. The results show that a reasonable design of suction and discharge springs can reduce pressure loss during the plunger suction process and improve the suction efficiency of the pump; The generation of negative pressure for plunger cavity suction is not closely related to spring design and clearance volume; The clearance volume is also a key parameter affecting the volumetric efficiency of the plunger pump, and a lower clearance volume can improve the response speed of the suction and discharge valve core.
