SS4改型电力机车作为重联补机(附挂)使用时,DK-1型电空制动机有时会发生制动缸不缓解的故障,致使闸瓦与轮箍长时间摩擦运行,造成机车轮箍发热弛缓,严重影响行车安全,针对一起典型故障,通过多次现场模拟试验和分析,提出防治措施。
SS4 modified electric locomotive used as a reconnection compensator (attached), DK-1 electro-pneumatic brake sometimes occurs brake cylinder does not ease the failure, resulting in a long friction brake shoe and wheel, causing the machine Due to the flare of the wheel rim, the traffic safety is seriously affected. Aiming at a typical fault together, a number of on-site simulation tests and analyzes are put forward to put forward the prevention measures.
