我们在修理液压设备时,发现由于材料性能不好,引起了活塞与缸壁、活塞杆与缸口导承密封口严重磨损、拉毛,甚至产生粘合等现象,遭成损坏漏油。修理时若全部改用耐磨的铜材配制磨损件,不但浪费铜材,而且强度往往不够;若采用镶套法,又会增加泄漏面,且往往几何尺寸也不允许。针对这一情况,我们采用了氧炔镀铜法。在维修和制造中,经过几年的实际考 When repairing the hydraulic equipment, we found that due to the poor performance of the material, the piston and cylinder wall, the piston rod and the cylinder port leading seal severe wear and tear, and even the phenomenon of adhesive bonding and other phenomena, was damaged oil spills. Repair if all use wear-resistant copper preparation of wear parts, not only a waste of copper, but the intensity is often not enough; if set method, will increase the leakage surface, and often geometric dimensions are not allowed. In response to this situation, we have adopted the method of copper plating. In the maintenance and manufacturing, after several years of actual test
