The driver knows that sometimes, especially in the summer, when the water tank of the Strong Diesel Forklift will have a very high temperature, it must stop, which will affect the work of the forklift. In severe cases, it will damage the parts. What are the causes of the Universal Diesel Forklift Trucks ? What about high temperature? How to solve it?
The reason why the forklift water temperature is too high
There are many reasons for the high water temperature: temperature control switches, pumps, sub-fans, water pipes rust, and poor water return can cause such a phenomenon. The temperature of the engine water temperature is mainly related to whether the thermostat is working normally, whether the pump can establish sufficient pressure, and whether the cooling fan can reach the standard speed. So how to check the water temperature of the forklift is not normal? The cooling system is generally composed of cooling fan, radiator, thermostat and other components. The cooling fan is often driven directly by the engine and the fan speed is consistent with the engine speed. The control of the cooling water temperature mainly depends on the thermostat.
The principle of the thermostat
The thermostat is also called a thermostat. The function is to automatically adjust the amount of water entering the radiator according to the temperature of the cooling water, and change the circulation range of the water to adjust the cooling capacity of the cooling system to ensure that the engine works in a suitable temperature range. The thermostat must maintain a good technical state, otherwise it will seriously affect the normal operation of the engine. If the main valve of the thermostat is opened too late, it will cause the engine to overheat; if the main valve is opened too early, the engine warm-up time will be prolonged and the engine temperature will be too low. At this time, it can be judged whether the working state of the thermostat is good. When the engine starts the cold running operation, if there is cooling water flowing out of the water inlet pipe of the water tank, the main valve of the thermostat cannot be closed; when the engine is cooled When the water temperature exceeds 70 degrees Celsius, there is no cooling water flowing out of the water inlet pipe of the water tank, indicating that the main valve of the thermostat cannot be opened normally, and repairs are needed.
