Will the screw air compressor stop automatically when the pressure comes?

Yes, when the pressure of the screw air compressor reaches the set upper limit, it will automatically stop.

The automatic start-stop function of screw air compressor is usually monitored and controlled by pressure sensor. When the pressure of the air compressor reaches the set upper limit, the pressure sensor will send a signal to the control system. After the control system receives the signal, it will control the air compressor to stop automatically to avoid the pressure from continuing to rise. Similarly, when the pressure of the air compressor drops to the set lower limit, the pressure sensor will send a signal to the control system. After the control system receives the signal, it will control the air compressor to start automatically to restore the air supply.

In addition, there are usually two ways to adjust the pressure of the screw air compressor:

1. air compressor pressure adjustment:

   • turn the pressure adjusting screw clockwise to increase the closing and opening pressures simultaneously.
   • Turn the pressure adjustment screw counterclockwise to reduce the closing and opening pressures simultaneously.

2. Differential pressure adjustment:

   • turn the differential pressure adjustment screw clockwise, the closing pressure remains unchanged, and the opening pressure increases.
   • Turn the differential pressure adjusting screw counterclockwise to make the closing pressure unchanged and the breaking pressure decrease.

By adjusting these parameters, the automatic start-stop function of the screw air compressor can be accurately controlled to meet different needs.

It should be noted that although the automatic start-stop function of the screw air compressor can improve the operating efficiency and service life of the equipment, it also needs regular inspection and maintenance during use to ensure the normal operation of the pressure sensor and control system. At the same time, if the air compressor is found to start and stop frequently or other abnormal conditions occur, it should be checked and eliminated in time to avoid damage to the equipment or affect production.
