近几年来,东风型内燃机车缸套裂纹是一个普遍存在的严重问题。在我段因缸套裂纹而临修的,1977年有49件、1978年有51件,占柴油机临修总件数的50％左右。气缸套裂纹或三座铜垫松动都可使燃烧室内的高压气体窜入水腔,并引起冷却水系统水位膨胀,在水箱表管上表现为机车虚水位。目前,判断故障处所常用充气反水法和拆喷嘴起机检查水箱水位变化的方法,判断过程较长,工作量也大,操作比较困难。当严重的
In recent years, the cylinder liner crack of the Dongfeng diesel locomotive is a ubiquitous serious problem. In my paragraph due to the cylinder liner cracks repair, there are 49 in 1977, 1978 51, accounting for 50% of the total number of diesel engine repair parts. Cylinder liner cracks or three loose copper pad can make the high-pressure gas into the water chamber, and cause the water level expansion of the cooling water system, manifested in the water tank tube locomotive virtual water level. At present, the method of determining the change of the water level of the water tank commonly used to check the water level of the water tank at the place where the fault is commonly used is to determine the process is long, the workload is also large, and the operation is difficult. When serious
