【摘要】 容积效率是衡量水压泵整体性能的关键指标，而深海环境下，球形配流阀的结构参数对水压泵的容积效率有显著影响。基于水压三柱塞径向泵，搭建AMESim模型，与实物台架实验数据对比，验证AMESim模型的可靠性。依据AMESim仿真分析，研究了球形配流阀阀芯、阀座及弹簧等结构参数对容积效率的影响。结果表明，吸入阀的结构参数较压出阀对容积效率的影响更大。通过回归分析，将选取的配流阀结构参数对泵容积效率的影响程度排序可知，在泵正常运行前提下，吸入阀阀座半锥角与吸入阀阀芯直径影响程度最为显著。更多还原

【Abstract】 Volumetric efficiency is a key index for measuring the overall performance of a hydraulic pump. In a deep-sea environment, the structural parameters of the spherical distributor valve exert huge impacts on the volumetric efficiency of the hydraulic pump. Based on a hydraulic three-piston radial pump, an AMESim model is built and its reliability is verified by correlating it with experimental data from a physical test bench. According to the simulation analysis of AMESim, this paper investigates the impact of structural parameters such as valve core, valve seat and spring of the spherical distributor valve on volumetric efficiency. Results indicate the structural parameters of the suction valve exert greater impacts on volumetric efficiency than those of the delivery valve. Moreover, through regression analysis, the impact of the selected distributor valve structural parameters on the pump’s volumetric efficiency is assessed. Under the normal pump operation, the semi-conical angle of the suction valve seat and the diameter of the suction valve core have the biggest impact.更多还原
