The water temperature of the water tank of an internal combustion forklift has been high and has not dropped. In summary, there are several reasons:
1. Failure of cooling system components: It may be a thermostat failure. The main valve of the thermostat opens too late or too early, which will cause the engine to overheat or the temperature is too low.
2. Water pump failure: The water pump is not working properly, such as the impeller is loose or the water pump is damaged, resulting in poor coolant circulation.
3. Fan failure: The fan belt is too loose, the number of revolutions is insufficient, the fan blades are deformed, the fan air volume is insufficient, etc.
4. There are some other reasons: For example, water quality problems, such as using well water, sea water, and water with high mineral content, will cause scale or chemical reactions in the waterway to damage the body. Water tank problems The water tank has little water, the water tank leaks, there is scale on the surface of the water tank, and the heat dissipation air duct is not smooth. The water channel is blocked and the water channel is not smooth, and there is a blockage phenomenon.
5. Improper use of the engine for a long time with high throttle and overload. Environmental impact The use of the ambient temperature is high.
6. Water temperature gauge or sensor plug problem The water temperature gauge is inaccurate or the sensor plug fails. There is a lot of air in the coolant. The engine coolant contains a lot of air. The temperature control switch, rusted water pipes, poor water return, etc. The temperature control switch is faulty, the water pipes are rusted, and the water return is poor.
