Specification

How to prevent the water temperature from being too high during use of the excavator?

1. Add enough coolant before use. Always check the coolant before each shift. If it is insufficient, add enough coolant.
2. While checking the coolant, check whether the fan belt is too loose. If it is too loose, tighten the fan belt. The requirement for tightening the fan belt is: When the engine is not rotating, press the belt vertically with your thumb with a force of 4-5 kg. In the middle, the depression is normal in the range of 10 to 15 mm.
3. While checking the cooling water, check whether the water tank is blocked. If it is blocked, clean the water tank. If there is too much scale in the water tank and the engine body, clean and clean the water tank in time.
4. When using the excavator, avoid long-term heavy-load operation, especially when the outside temperature is high.
5. When the water temperature of the diesel engine in the excavator exceeds 95℃ and the boiler is boiling, stop immediately, but do not turn off the engine immediately. At this time, it is strictly forbidden to add cold liquid or pour it with cold water. The engine should be operated at a medium speed and wait until the water temperature drops to When the temperature is below 60℃, turn off the flame and check again.
6. It is strictly forbidden to open the water tank cover when it is high temperature to avoid being burned by the high temperature water vapor spray. Open it after the water temperature drops to normal temperature.
Generally, these methods can solve the high temperature problem of the engine. If it is still high temperature, it is best to ask professionals to further check, such as whether the distance between the fan and the water tank and the relative position of the air duct of the water tank are appropriate, whether the heat dissipation area of ​​the water tank matches the engine, Whether the air volume of the fan is low, whether it is necessary to increase the speed of the fan, increase the diameter of the fan, and increase the fan blades.
