我段担当的运用区段曲线多,半径小,机车轮缘磨耗严重,机车落轮焊修任务十分繁重,有时还形成入库排队落轮的现象。据不完全统计,仅1970年6-10月落轮32台次。新旋削的轮缘通常走行70000公里左右就磨耗到限,烧焊的轮缘仅能走行30000公里左右,个别机车甚至走行不到10000公里,轮缘就磨耗到限。东风1402号机车从出厂到段后仅走行10000公里,其第一轮缘就磨耗到限。东风1261号机车1970年10月17日第一轮对落轮焊修,
I play a section of the section of the curve, small radius, locomotive wheel wear serious locomotive drop welding repair task is very heavy, sometimes forming the phenomenon of storage queuing off. According to incomplete statistics, there were 32 rounds of landing in June-October 1970 alone. New spin-cut rims usually travel about 70,000 kilometers to wear to the limit, welding the rim can only walk 30,000 kilometers or so, individual locomotives and even less than 10,000 kilometers, the rim wear to the limit. Dongfeng 1402 locomotive from the factory to the paragraph after only 10,000 kilometers, its first round of wear on the edge of the limit. Dongfeng 1261 locomotive October 17, 1970 The first round of landing round repair welding,
