对国产和国外产轴向柱塞泵柱塞滑靴的结构进行研究,可以发现,即使在泵使用条件差别不大时,滑靴的结构也会有很大不同。滑靴的正面有的只有密封台阶(图1a),有的既有密封台阶又有支承台阶(图1b)。至 The research on the structure of axial piston pump plunger sliding shoes made in China and abroad shows that the structure of the sliding shoes will be very different even when the pump conditions are not too different. Some of the front of the shoe has a sealing step (Figure 1a), some has both a sealing step and a supporting step (Figure 1b). to
