目前在冶金地质系统钻探生产中使用的北京—600型单缸油压钻机近百台,由于设计、加工及使用中存在一些问题,影响设备的正常使用,尤其是油缸漏油问题。经调查认为油缸漏油的主要原因是:1.油缸各零件不同心或各接触面的间隙太大,以致组装后油封在某一方向封不住而漏油。2.由于活塞(2)的材质是钢的,在钻进中因活 At present, nearly 100 sets of Beijing-600 single-cylinder hydraulic drilling rigs are used in the drilling and production of metallurgical geological systems. Due to some problems in the design, processing, and use, the normal use of the equipment is affected, especially the oil leakage problem of the cylinders. According to the investigation, the main reasons for the oil leakage of the oil cylinders are: 1. The gaps between the parts of the fuel tank that are not centered or at the contact surfaces are so large that the oil seals cannot be sealed in one direction and the oil leaks after assembly. 2. Because the piston (2) is made of steel
