In summer, the excavator is prone to failure caused by high engine temperature when working. Some people will pour water on the engine to cool down or directly open the radiator of the water tank to cool down. However, the treatment methods of these excavator engine high temperature faults are wrong. The occurrence of high temperature fault of excavator engine is closely related to the maintenance of excavator. If the maintenance of the excavator can be done well at ordinary times, the high temperature fault of the excavator engine can be avoided to a certain extent. This article will explain some things that the excavator should not do to the excavator engine under high temperature environment.
1. Open the radiator after the engine has a high temperature fault
Some people will directly open the radiator of the water tank to cool down after the high temperature fault occurs when the excavator works. In fact, this method is wrong. Because the temperature of the radiator is also very high after the high temperature fault, if you are eager to open the radiator cover at this time, you may be scalded by the hot water. Water should be added after the excavator cools naturally.
2. Stop immediately after high temperature fault
The excavator cannot be stopped immediately after high temperature fault occurs. Because the engine temperature is extremely high at this time, if the engine is shut down immediately, some metal in the radiator will fall off. It may cause the piston, piston ring and cylinder liner to stick together and cause other faults.
3. Directly flush the engine with cold water
Some people will directly flush the engine with cold water after high temperature failure of the excavator. So as to reduce the engine temperature. In fact, although this method can rapidly reduce the temperature, directly flushing the engine with cold water may cause damage to some parts inside the engine, and even may cause the engine block, cylinder liner and other parts to explode.
4. Add cold water directly to the radiator
Some people will directly add cold water to the radiator, which is easy to burn.
