Many people want to know how to debug the vacuum pressure switch, so let's take you to find out.

Open the lock nut, and then rotate the adjustment nut in the forward or reverse direction until the pointer points to the required pressure value. The pressure switch generally has 2 knobs. Use a screwdriver to rotate it, open the lock nut before rotating, and rotate in the positive direction to increase the pressure, and in the opposite direction to decrease.
How vacuum pressure switch works:
1. When the pressure in the system exceeds or falls below the limited safety pressure, the disc in the sensor immediately shifts, and the connecting guide rod is used to push the switch connector to connect or cut off. The vacuum pressure switch manufacturer tells you that when the pressure drops to or rises to a limited recovery value, the disc will reset immediately and the switch will reset itself.
2. Or a simple understanding is that the vacuum pressure switch manufacturer tells you that when the measured pressure is greater than the limit value, the free interface of the elastic part will be displaced, and the switch part can be directly or by pushing the switch part to change the on-off condition of the switch part, which has the ability to achieve the measurement. result of stress.
3. This switch is passive, and it is not necessary for the user to use it manually. The water pressure can do all this. When the pressure drops, the normally open contacts come up, complete the circuit and turn on the pump. After reaching the commissioning pressure, the contacts open again, turning off the pump. The vacuum pressure switch manufacturer tells you that some switches and diaphragms in the water line are pressed against the piston and operate in conjunction with the spring inside the unit. The spring pressure is adjusted by adjusting the screw. All the pressure on the diaphragm makes the switch close. When the pressure drops, the switch opens.
