石油钻机上的各种零、部件的轴、孔及工作平面,常因磨损而失效。由于钻机零件的尺寸较大,所以采用金属粉末热喷涂或槽镀修复都受到一定的限制。为此,我们从1982年底开始,培训有关电刷镀方面人员。经过一段时间的试验后,在钻机修理中就广泛采用了这项新技术。截止到1986年3月底,我们共修复了F320-3DH、F200-2DH、大庆Ⅱ型等钻机的绞车滚筒轴、中间轴、Ⅰ、Ⅱ、Ⅲ号传动轴、带泵轴、转盘变速箱的输入轴、泥浆泵的曲拐轴、涡轮变矩器的输入、输出轴、压风机曲轴、NS
Oil drilling rig on a variety of zero, parts of the shaft, hole and work plane, often due to wear and tear failure. Due to the larger size of rig parts, thermal spraying of metal powder or groove plating repair are subject to certain restrictions. To this end, we have been training personnel on brush plating since the end of 1982. After a period of experimentation, this new technology is widely used in rig repairs. As of the end of March 1986, we repaired the winch drum shafts, countershafts, drive shafts I, II, and III, with pump shaft and dial transmission of F320-3DH, F200-2DH and Daqing type II drilling rigs Shaft, mud pump crank shaft, turbine torque converter input and output shaft, compressor fan crankshaft, NS
