目前全路很多蒸汽机务段使用的蒸汽轨道吊车的汽缸密封装置,仍沿用石棉盘根,在技术上存在许多弊病。为了解决存在的问题,沈阳铁路局在大安北机务段成功地改造了蒸汽轨道吊车汽缸密封装置,经实际应用取得了良好效果。 原密封装置存在许多弊病,大安北机务段使用的203型15t蒸汽轨道吊车汽缸密封装置用的是石棉盘根。由于石棉绳耐磨性差,而吊车在作业时,活塞杆处于往复运动状态,盘根绳磨耗很快,盘根与活塞杆之间产生间隙,加之汽缸内蒸汽的压力,不可避免地要出现漏泄。改造前处理漏泄的办法无非是填
At present, many steam cylinder locomotives across the road steam rail crane cylinder seals, still using asbestos packing, there are many technical shortcomings. In order to solve the existing problems, the Shenyang Railway Bureau successfully renovated the cylinder sealing device of the steam rail crane in Da’an North Locomotive Depot. The practical application has achieved good results. There are many shortcomings of the original seal, Da’an North locomotive depot 203 15t steam rail crane cylinder seal is used asbestos packing. As the asbestos rope wear resistance is poor, and crane operation, the piston rod in reciprocating motion, packing rope wear quickly, packing and piston rod gap between, coupled with the pressure of steam in the cylinder, inevitably want to leak . Remedial measures before the leak is nothing more than fill
