1.使用⑴发动机启动前,应打开机体放水阀并加入60~70℃的热水预热,直到机体放水阀流出热水后,关上放水阀,启动发动机。⑵发动机停机不再工作时,应停放在机库内平坦处,待水温降至40~50℃时打开放水开关,摇转曲轴,使水泵壳体内的水全部排净。也可以在冷却系中加防冻液不放水保管。⑶对油箱和油底壳加热时,不要用明火,一般都是用热水对柴油和机油进行预热,用炭火或热水预热油底壳、喷油嘴、高压油管和机体,这样能避免减少发动机寿命和影响机油质量,待预热充分后,再启动发动机。
1. Use ⑴ engine start, should open the body drain valve and add 60 ~ 70 ℃ hot water preheating, until the body drain valve out of hot water, turn off the drain valve, start the engine. ⑵ engine stop working no longer, should be parked flat in the hangar, until the water temperature dropped to 40 ~ 50 ℃ open the water switch, rocking the crankshaft, so that the water pump shell all drain. Can also add antifreeze in the cooling system does not drain custody. ⑶ on the tank and the oil pan heating, do not use open flame, are generally hot water on the diesel and oil preheating, charcoal or hot water with a warm pan, nozzle, high pressure tubing and the body, so that Avoid reducing the engine life and affecting the quality of the oil. After the preheat is sufficient, start the engine again.
