1.按技术保养规程定期检修喷油器 (1)由于新喷油嘴一般都涂有一层防锈油,因此在更换新喷油嘴时(包括清洗旧油嘴),一定要用干净的柴油或煤油仔细清洗,以清除喷油嘴偶件表面的污杂物和防锈油,并将针阀在针阀体内反复抽动和转动几次。 (2)拆装喷油器时,应注意清洗针阀体台肩下端面与紧帽支承台阶面的脏物,并检查喷油器紧帽是否变形。如变形轻微,可用圆锥将变形处修正;若变形严重,则应重新车制一只。误用已变形的紧帽,容易使喷油嘴针阀体变形,针阀运动卡滞,工作时针阀卡
1. Regular maintenance according to technical maintenance procedures Injector (1) Since new injectors are generally coated with a layer of anti-rust oil, so when replacing the new nozzle (including cleaning the old nozzle), be sure to use clean diesel or Carefully clean the kerosene to remove contaminants and rust-preventive oils from the surface of the injector coupling and twitch and rotate the needle several times in the needle valve body. (2) When disassembling and injecting the injector, pay attention to cleaning the dirt on the lower surface of the shoulder of the needle body and the supporting surface of the tight cap, and check whether the tight cap of the injector is deformed. If the deformation is slight, the cone can be used to correct the deformation; if the deformation is serious, it should be a new car. Misuse has been deformed tight cap, easy to deform injector nozzle body, needle movement stuck, work when the valve card
