How to use the expansion pot belt sensor？
The main use of the expansion pot belt sensor is to monitor the pressure and temperature of the automotive cooling system to ensure the safe operation of the system. The expansion pot, commonly known as the kettle, is a structural component of the automotive cooling system. When the engine is running, the antifreeze circulates in the cooling water channel and flows through the expansion pot. If the system pressure is too high or the antifreeze is excessive, the excess gas and antifreeze will flow out of the by-pass water channel of the expansion pot to prevent the cooling system pressure from excessive and causing tube explosion .
When using the expansion pot strap sensor, follow these steps :
Installing the sensor : Correctly install the sensor on the expansion pot to ensure that the sensor is closely fitted to the component being measured to prevent interference signals from being received.
Connected circuit : Connect the sensor to the circuit to ensure that the circuit can work properly and the output signal of the sensor can be read correctly.
Adjusting sensitivity : According to the actual needs, by adjusting the sensitivity of the sensor, so that it can accurately measure the pressure and temperature changes of the cooling system.
Adjusting the zero point : After installing the sensor, adjust the zero point of the sensor to ensure that the output signal of the sensor is zero when the cooling system is in normal condition.
Calibrate the sensor : calibrate the sensor regularly to ensure that the output signal of the sensor meets the actual measurement requirements. If necessary, it can be calibrated by the standard measuring equipment in the laboratory .
Through the above steps, it can be ensured that the expansion pot belt sensor accurately monitors the pressure and temperature of the car cooling system to ensure driving safety.
The reason why the water temperature rises due to the fault of the expansion lid
The expansion pot cover is an important part of the automobile cooling system, its main function is to store excess coolant, prevent the coolant from boiling and overheating, so as to ensure the normal operation of the vehicle. If the expansion lid fails, it may cause the coolant to not flow properly, resulting in excessive water temperature of the vehicle. The consequences of too high water temperature are very serious, which may affect the normal operation of engine, and may even cause the engine to overheat and burn out.
Symptoms of a malfunctioning expansion lid
The main symptoms of expansion lid failure include:
Antifreeze spray out of tank cover : Coolant spills out under pressure because the expansion lid does not seal effectively.
engine overheating : The coolant flow to the engine is reduced, resulting in the engine running heat can not be effectively dissipated, resulting in engine overheating.
The solution is
If the water temperature is too high due to the fault of the expansion lid, you can take the following measures:
Checking and replacing expansion lid : If the problem is with the expansion lid, it may need to be replaced with a new lid or the entire expansion pot.
Keep cooling system clean : Periodically check the cleanliness of the cooling system to ensure that no impurities clog the cooling system.
Preventive measures
To prevent excessive water temperature caused by the failure of the expansion lid, you can take the following measures:
Check cooling system : Check all parts of the cooling system regularly to ensure that they are working properly.
Maintain adequate coolant : Ensure adequate coolant to avoid excessive water temperature due to insufficient coolant.
