在内燃机车修理过程中,零部件的清洗是一个重要的环节。清洗质量的好坏直接影响到机车的正常运行,而且目前零部件清洗的工作量大、劳动条件差。因此,采用先进的清洗方法及选用合适的清洗介质是十分重要的。由于清洗介质是直接参于清洗过程的,因此它的性能如何,对提高清洗质量有很大的关系。长期以来,铁路机车车辆的零部件大多采用碱性清洗液及石油溶剂来清洗,但由于内燃机车的零部件加工精密、清洗要求高,另外还有不少铜、铝及其合金的制件,故这种清洗介质已不能满足要求。近几年来,在内燃机车修理中采用了一种新型清洗介质──金属清洗剂,经过一定时间
In the diesel locomotive repair process, cleaning parts is an important part. The quality of the cleaning directly affects the normal operation of the locomotive, and the current parts cleaning workload, poor working conditions. Therefore, the use of advanced cleaning methods and selection of suitable cleaning media is very important. Since the cleaning medium is directly involved in the cleaning process, its performance is very much related to the improvement of the cleaning quality. For a long time, most locomotive and rolling stock parts are cleaned with alkaline cleaning solutions and petroleum solvents. However, due to the precision machining of parts and components of diesel locomotives and the high cleaning requirements, there are also many parts of copper, aluminum and their alloys, Therefore, this cleaning medium can no longer meet the requirements. In recent years, diesel locomotive repair using a new type of cleaning media ─ ─ metal cleaning agent, after a certain period of time
