轴向柱塞泵的柱塞顶部的滑块与斜盘之间,以及油缸和配流盘之间都存在着相对运动(参看图1),如果这些地方的金属面彼此接触压力太大,会引起摩擦和烧损,如果接触面压力太小,则间隙增大产生洩漏。为使接触面处之接触压力和油膜的压力彼此平衡,要求接触面间保持适当的间隙,以防止烧损和增大洩漏。因此,研究在这样小的问题隙内油的洩漏,可用流体压力的推力计算法来说明。 Axial piston pump piston at the top of the slider between the swash plate, and between the cylinder and the valve plate there is a relative movement (see Figure 1), if the metal surface in these places contact pressure is too large, it will cause Friction and burning, if the contact pressure is too small, the gap increases leakage. In order to balance the contact pressure at the contact surface and the pressure of the oil film, it is required that an appropriate gap be maintained between the contact surfaces to prevent burning and increase leakage. Therefore, the study of oil leakage in such a small problem gap can be used to illustrate the fluid pressure thrust calculation.
