灵山机务段配属前进型机车26台,其中水箱容积为50kL的机车15台。在这15台机车中有11台机车的水箱侧板存在惯性裂漏,裂漏处所均为左前方内侧板(加煤机传动轴右侧),裂纹方向为纵向,短的有100mm,长的达300mm,最少的有1道裂纹,多的达3道裂纹。在洗修时,每次都要对这些裂纹进行焊修,结果是屡焊屡漏,不是原焊缝又裂开,就是又出现新的裂纹。因此时常出现碎修焊水箱,造成洗修出现重复修,浪费人力、物力;经常发生碎修,存在着发生临修甚至机破的隐患;到了冬运期间,由于水箱漏水冻结了煤水车的制动装置,减弱了煤水车的制动力,甚至使煤水车的制动不起作用;经常碎修,浪费水资源。 通过对前进型六轴水柜左前方小水槽内侧板易裂漏的惯性焊修之原因所作分析,前进型六轴煤水
Lingshan locomotive depot is equipped with 26 forward-type locomotives, of which 15kW locomotive capacity of 50kL. In these 15 locomotives, 11 locomotives have inertia cracks in the side plates of the water tank. The leakage places are both left front inner plates (the right side of the stoker shaft), the crack direction is vertical, and the short one is 100 mm long Up to 300mm, at least a crack, up to 3 cracks. During the repair, every time these cracks should be welded and repaired, the result is repeated welding repeated leaks, not the original weld and split, that is, there are new cracks. So often appear broken repaired welding water tank, resulting in repeated repair washing repair, waste of manpower and material resources; frequent shatter repair, there is a temporary repair and even the risk of break; to the winter transport period, due to leakage of water tank frozen coal car system Moving device, weakened the braking power of coal-water vehicles, coal-water vehicles and even make braking ineffective; often broken repair, waste of water resources. Based on the analysis of the cause of the easy-to-crack leakage of the inner side of the small tank in the front left of the six-axis water tank,
