当前,很多国产内燃机车装有JZ—7型空气制动机,经过一段时间的运用,一些零件会产生不同程度的磨耗,影响制动机的正常使用。目前各段检修标准不统一,也无一套完整的磨耗限度,我段在日常检修作业中,对JZ—7型空气制动机零件磨耗过甚时所产生的现象和检查处理方法及主要件的尺寸限度,积累了一些经验,现整理出来供有关部门参考。 At present, many domestic diesel locomotives are equipped with JZ-7 air brakes. After a period of use, some parts will have different degrees of wear and affect the normal use of the brake. At present the various sections of the maintenance standards are not uniform, there is no complete set of wear limits, I paragraph in the daily maintenance operations, JZ-7-type air brake parts wear too late when the phenomenon and check the treatment methods and the main pieces Size limits, accumulated some experience, now sorted out for the relevant departments for reference.
