How to adjust the air pressure of the air compressor pressure switch

There are two knobs on the pressure switch, one for adjusting the upper pressure limit and the other for adjusting the lower pressure limit. Clockwise is positive and counterclockwise is negative. It is best to have a pressure gauge on the air compressor, so that you can know which button you adjust is the upper limit, which is the lower limit and how much to adjust. In addition, it is necessary to cooperate with AC contactor to achieve the effect of automatic pressure switch.

Air compressor is a kind of equipment used to compress gas. The air compressor is similar to a water pump in structure. Most air compressors are reciprocating pistons, rotating blades or rotating screws. Centrifugal compressor is a very large application.

According to the working principle, it can be divided into three categories: positive displacement compressor, dynamic compressor (speed compressor or turbine compressor) and thermal compressor.

According to lubrication methods, it can be divided into oil-free air compressor and oil-lubricated air compressor.

According to the performance, it can be divided into: low noise, frequency conversion, explosion-proof and other air compressors.

There are many categories, so you can check them yourself.
