Air compressor pumps air. Will it stop automatically if the air pressure is enough?

Yes, the air compressor will automatically stop pumping when the air pressure reaches the set value.

The working principle of an air compressor usually includes a pressure switch (or pressure sensor and control system) to monitor the air pressure in the gas tank. When the air pressure is below the set minimum value, the air compressor starts and starts to pump air to increase the air pressure in the gas tank. When the air pressure gradually increases and reaches the set maximum value, the pressure switch will be triggered and the air compressor will automatically stop working. This process ensures that the air pressure in the gas storage tank is always maintained within the set range to meet the gas consumption needs of the pneumatic equipment.

Specifically, the automatic start-stop function of the air compressor is realized through a pressure switch. There is an elastic element inside the pressure switch (such as glue pads and springs) that when the air pressure rises, the elastic element is compressed and displaced. When the air pressure reaches the set value, the displacement of the elastic element will trigger the switch action, disconnect the power supply of the air compressor and stop it from working. On the contrary, when the air pressure drops to the set minimum value, the elastic element returns to its original state, the switch is closed and the air compressor restarts and the air compressor is restarted to pump.

It should be noted that different models and brands of air compressors may have differences in air pressure setting values ​​and automatic start and stop functions. Therefore, when using an air compressor, you should refer to its operating manual or consult the supplier for specific setting methods and parameters. In addition, in order to ensure the normal operation of the air compressor and extend its service life, it should also be maintained and maintained regularly.
