| 摘 要： | 提出了一种织构化配流副泄漏量的新计算方法,研究了圆柱形微凹坑直径、深度和面积率对配流副泄漏量的影响,并进行了初步的机理分析.结果表明:随着微凹坑深度的增加,泄漏量随之减小；在相同的面积率下,较小直径的微凹坑具有较小的泄漏量；轴向柱塞泵配流副缸体的转动速度对泄漏量几乎没有影响；配流副工作压力与泄漏量成正比.计算结果可为选择符合配流副工况的圆柱形微凹坑几何参数提供指导.

| Abstract: | A new method for calculating leakage of textured port plate pair is suggested in this paper.The effects of micro-pits’ diameter,depth and area ratio on leakage were studied,and the basic mechanism were analyzed in the same time.The main results show that the deeper the micro-pits’,the less the leakage;smaller dimple diameter result in smaller leakage under the condition of same area ratio;rotational speed of cylinder body hardly affects leakage;the leakage is directly proportional to work pressure of port plate pair.The results of the new calculating method can serve as guidance for selecting geometric parameter of micro-pits based on port plate pair’s working condition. |
