The automobile air-conditioning pressure switch detects the pressure of the air-conditioning pipeline, and then transmits the pressure signal to the air-conditioning control system to protect the air-conditioning compressor and the pipeline! The air conditioner can work normally only whe...
The pressure switch is mainly used in the refrigeration system, in the pipeline circulation system of high pressure and low pressure, to protect the abnormal high pressure of the system to prevent damage to the compressor.
After being filled, the refrigerant flows into the aluminum shell (that is, inside the switch) through the small hole under the aluminum shell. The inner cavity uses a rectangular ring and a diaphragm to separate the refrigerant from the electrical part ...
