变形对轴向柱塞泵柱塞副泄漏量的影响研究

Influence of Deformation on Leakage of Piston and Cylinder in Axial Piston Pump

泄漏量是影响柱塞泵工作性能的重要因素。利用ANSYS-Workbench进行柱塞泵变形分析,研究柱塞副间隙尺寸的变化规律;用柱塞副泄漏量修正公式计算变形后的泄漏量,并将其与理想状态泄漏量进行对比,揭示变形对柱塞副泄漏量及容积效率的影响规律。

Leakage is an important factor which affects the working performance and life of piston pump. ANSYS-Workbench was used to analyze the deformation of the piston pump, researching the change rules of the interval between piston and cylinder. Pistonpair leakage correction formula was used to calculate deformed leakage. It was contrasted with the ideal leakage without regard to deformation and the influence of the deformation on the leakage was revealed.
