The thermostat thermostat function is called, automatically adjust the temperature of the cooling water into the radiator according to the level of the water cycle range changes in water, to adjust cooling capacity of the cooling system, ensure that the engine work in the suitable temperature range. Baotou North rush heavy truck fittings thermostat must maintain good technical condition, otherwise it will seriously affect the normal work of the engine. If the thermostat main valve opens too late, it will cause overheating of the engine; the main valve is too early to open, the engine warm-up time is extended, so that the engine temperature is too low.
The thermostat can determine whether the good working condition, when the Baotou beiben heavy truck parts cold car engine began operation, the water supply chamber water inlet pipe and cooling water flow, the main valve is not closed thermostat; when the engine cooling water temperature more than 70 degrees Celsius, water tank room the water inlet pipe without cooling water outflow, the thermostat main valve cannot open normally, then it needs repairing. The thermostat can be checked in the car as follows:
Inspection after engine starting:
Open the Baotou beiben heavy truck parts radiator cap, if the radiator cooling horizontal static, indicates that the thermostat is working properly, otherwise, said thermostat work properly. This is because the water temperature is below 70 DEG C, cylinder contraction expansion thermostat, the main valve is closed; when the water temperature is higher than 80 DEG C, the expansion cylinder expansion, the main valve is gradually opened, inside the radiator circulating water begins to flow. When the water temperature meter indicates below 70 degrees Celsius, if the radiator inlet pipe has water flow and the water temperature is warm, then the main valve of the thermostat is not closed tightly, and the cooling water is too early to cycle.
