众所周知,液压泵的摩擦副性能直接影响着泵的寿命,尤其是配油摩擦副、油腔工作副等关键摩擦副对泵的性能和寿命的影响更为明显。近年来,人们一方面在设计和选材上不断设法改进摩擦副性能,另一方面,通过对摩擦副表面热处理来改善摩擦的性能,也越来越引 As we all know, hydraulic pump friction directly affect the performance of the pump life, especially with the oil friction pair, oil chamber deputy deputy key friction pairs of the performance and life of the pump more obvious. In recent years, on the one hand, people constantly try to improve the performance of friction pair on the design and material selection. On the other hand, the performance of friction is improved by heat treatment on the friction pair surface,
