我们是一个为筑路工程服务的机修队,点多线长,经常流动,不可能配备成套的修理设备。为了工程的需要,本着自力更生的精神,经常担负一些机车的大修任务,除搪缸、磨曲轴、搪主轴瓦等必须送到厂里去修补,其它问题都在执行修理工艺的基础上,因地制宜,土洋结合,自行解决。我们承修了一台东方红—75拖拉机的发动机(4125A柴油机)。经空转磨合,机车开出工房,用一挡速度空驶磨合前行才400米,排气管突然冒黑烟,发动机声音变沉重,接着自
We are a mechanical repair team that services road construction projects. They are multi-line long and often flow. It is impossible to provide complete repair equipment. In order to meet the needs of the project, in the spirit of self-reliance, we often assume the task of overhauling some locomotives. In addition to boring cylinders, grinding crankshafts, and boring spindles, they must be sent to the factory for repairs. Other problems are based on the implementation of repair techniques and are based on local conditions. , combined with earth and ocean, self solve. We undertook the engine of a Dongfanghong-75 tractor (4125A diesel engine). After idling, the locomotive opened out of the workshop, and it was only 400 meters before running in with a block of speed. The exhaust pipe suddenly emitted black smoke, and the engine sound became heavy, and then
