汽室阀杆是蒸汽机车上的重要零件,通常,它在磨耗过限后,即被报废。为了延长汽室阀杆的使用寿命,我厂运用了镀铁技术进行修复。两年多来,在一批蒸汽机车上试装了242根经镀铁工艺修复的汽室阀杆(恢复径向尺寸0.5～3毫米),成功率达到90％。一、镀铁汽室阀杆的使用情况与分析 1979年,对长春机务段配属的前进型111号机车进行调查。在这台机车的一侧装有一根经镀铁工艺恢复尺寸的汽室阀杆。该机车在干线上进行90863公里后进行拆检,测得镀铁汽室阀杆的磨耗量为0.2毫米,另一根
Steam chamber stem is an important part of the steam locomotive, usually, it worn out, it was scrapped. In order to extend the service life of the steam chamber stem, I plant the use of iron plating technology to repair. For more than two years, a total of 242 vapor-filled stems (restored to radial dimensions of 0.5 to 3 mm) were plated on a steam locomotive with a success rate of 90%. First, the use of iron-plated steam chamber stem situation and analysis In 1979, the Changchun Locomotive Depot associated with the forward type 111 locomotive to investigate. On the side of the locomotive is a steam chamber stem with resumed dimensions of the iron plating process. The locomotive on the trunk line 90,863 km after the dismantling inspection, measuring the wear of the iron-plated steam chamber stem 0.2 mm, the other
