How to adjust the pressure of air compressor

you can.

Adjustment method:

if it is a spring resettable type, then there should be something on the top that can rotate, turn up to increase the pressure, turn down to reduce the pressure.

Tighten the screw on the top of the safety valve, but not once. Adjust it slowly. But it's dangerous.

The safety pressure of the safety valve is adjusted by the local technical supervision department. It is suggested that special personnel should be invited to adjust it.

General approach:

generally speaking, the air compressor is low pressure automatic start, high pressure automatic stop. No matter what kind of air compressor, there are usually pressure switches or pressure sensors to achieve automatic control. Therefore, if you need to adjust the pressure of the air compressor, you only need to adjust the operating range of the pressure switch and the starting pressure set on the sensor.

The pressure switch has a RANGE and DIFFE, which can be adjusted according to needs. diffe is generally motionless. If the pressure sensor is to be adjusted, it only adjusts the set start-stop pressure value rather than adjusting the pressure sensor itself. If there is a display panel on the air compressor, there is usually a set pressure item, and the value is adjusted there to change the start and stop pressure.

Note:

the pressure switch of the air compressor must be adjusted by professionals, and the general user cannot adjust it arbitrarily.

2. The air compressor has a rated operating pressure. This pressure refers to the pressure when it is disconnected. For example, the general air compressor operating pressure is 7kg/cm2, and the maximum pressure when it is disconnected cannot exceed 7kg/cm2 to avoid danger.
