提高加油质量和使用清洁的柴油,对以柴油机为动力的建筑机械有着十分重要的意义。油箱中的柴油同空气和箱壁接触,会生成一些污垢沉入箱底或附着在箱壁上,在加油或工作过程中,也难免有灰砂、尘土或水分被带入油箱,油箱中的这些杂质必须及时清除干净。否则,加入的干净柴油也会受到污染而造成燃油泵中的柱塞、出油阀、喷油器针阀等精密偶件的
Improve the quality of refueling and the use of clean diesel fuel is of great significance to diesel-powered construction machinery. Diesel fuel in the fuel tank comes in contact with the air and the wall of the tank. It will generate some dirt that sinks into the bottom of the tank or adheres to the tank wall. In the process of refueling or working, it is inevitable that sand, dust or moisture will be carried into the tank. These are the fuel tanks. Impurities must be removed in time. Otherwise, the added clean diesel oil will also be contaminated and cause the precision of the plunger, the oil valve, and the injector needle valve in the fuel pump.
