What are the reasons for the high water temperature of diesel engine and how to deal with it?

1. The unit is overloaded and the work of the diesel engine itself becomes larger. Treatment method: adjust the diesel engine to the rated working state (whether the rated pressure of the air compressor is set high and the rated speed of the diesel engine is set high?)

2. Whether the fan belt slips, resulting in insufficient fan speed and insufficient cooling air volume.

3. The air duct of the water tank is blocked. If the blockage is serious, the water tank can be removed and cleaned with a high-pressure water gun.

4. The water channel inside the water tank is blocked. (if a good antifreeze is not used, the inside of the water tank may scale and affect the coolant circulation. Special descaling agent should be used for waterway cleaning and descaling)

5. The structure of water tank head is damaged (sdp660h and 920k water tanks have poor heat dissipation due to the existence of water supply channel partition at the upper head and the damage of intermediate partition, and the hot water passes through the water supply channel)
