1.使用前必须先磨合。要严格按照出厂说明书规定的试运转程序进行磨合,转速由低到高,负荷由轻到重,以消除零件摩擦面的加工痕迹,使其表面光滑。2.及时清理排气管。操作中很多机手忽视对机车排气管道的维护,这会使排气管道截面变窄,排气受阻,导致发动机耗油率提高,功率下降,使机车出现“过热”现象。因此,一般情况下,至少每季度应对排气管积碳进行一次清理,确保柴油机排气通畅。 1. Before use must be run. In strict accordance with the factory manual test run procedures for running-in, speed from low to high, the load from light to heavy, in order to eliminate parts of the friction surface processing marks, so that the surface smooth. 2. promptly clean the exhaust pipe. Many operators neglect to maintain the locomotive exhaust pipe in operation, which will narrow the exhaust pipe section and exhaust the exhaust gas, resulting in the increase of the fuel consumption of the engine and the decrease of power, resulting in the locomotive “overheating” phenomenon. Therefore, under normal circumstances, exhaust gas coke should be cleaned at least once a quarter to ensure the diesel exhaust is unobstructed.
