我段过去架修的机车经常在水阻台上发生抱缸事故。这样既延长了架修时间,又浪费了配件,对人身、设备安全危害也极大。针对这个问题,我们总结了过去的一些经验,在检修工艺上和水阻磨合等方面采取了一些措施,这样从1977年下半年起一年多时间里,共架修了26台机车,在水阻台上就没有发生抱缸事故,而且交车后这些机车运用到大轮前状态仍良好。采取的措施如下:(一)在检修工艺上1.尽量调小瓦的油润间隙,使瓦隙恢复到原形。在轴颈椭圆度接近或大于0.15毫米时,瓦隙应调到0.15毫米左右。如果架修时瓦隙接近0.3毫米或大于0.3毫米时应调小瓦隙,否则不到下次架修或不到大轮公里时瓦隙
In the past, the locomotives that I used to build and repair often crashed on the water stop. This will not only extend the time frame repair, but also a waste of accessories, the personal, equipment safety hazards are also great. In response to this problem, we summed up some of the past experiences and took some measures in terms of overhauling technology and water resistance. In this way, from the second half of 1977 to a total of more than 26 years, a total of 26 locomotives were repaired. There was no collision happened on the stage of the cylinder, and after the delivery of these locomotives to the big wheel before the state is still good. Measures taken are as follows: (a) in the overhaul process 1. try to adjust the tile of the oil margin, the tile back to its original shape. In the journal ovality is close to or greater than 0.15 mm, the tile should be adjusted to about 0.15 mm. If the repair clearance when the gap is close to 0.3 mm or greater than 0.3 mm should be adjusted when the small gap, or less than the next time the repair or less than a large kilometer K
