How to adjust the air pressure of air compressor

Different air compressor switches have different adjustment methods. One is that the pressure difference is fixed by the switch itself, and only the automatic stop pressure is adjusted, and the pressure rises. This kind of knob is debugged with two straight screwdriver on the switch, and the two knobs must be adjusted in unison, otherwise it will stop when moving together, and start when it stops, which will burn out the electrical appliance. The other is to adjust the start pressure (low pressure) and stop pressure (high pressure).

Air compressor pressure adjustment:

1. Turn the pressure adjusting screw clockwise, and the closing and opening pressures will increase synchronously.

2. Turn the pressure adjusting screw counterclockwise, and the closing and opening pressures will be reduced simultaneously.

Air compressor pressure difference adjustment:

1. Turn the differential pressure adjusting screw clockwise to keep the closing pressure unchanged and increase the opening pressure.

2. Turn the differential pressure adjusting screw counterclockwise to keep the closing pressure unchanged and the opening pressure decreased.

Features:

The compressor is directly driven by the motor, which makes the crankshaft rotate and drives the connecting rod to make the piston reciprocate, causing the volume change of the cylinder.

Due to the change of pressure in the cylinder, air enters the cylinder through the intake valve and the air filter (muffler). In the compression stroke, due to the reduction of cylinder volume, compressed air enters the air storage tank through the exhaust pipe and the one-way valve. When the exhaust pressure reaches the rated pressure of 0.7MPa, it is automatically stopped by the pressure switch.

When the pressure of the gas storage tank drops to 0.5-0.6MPa, the pressure switch is automatically turned on and started. Air compressor is the core equipment of pneumatic system and the main body of electromechanical bleed air source device. It is a device that converts the mechanical energy of prime mover (usually motor or diesel engine) into gas pressure energy, and it is a gas pressure generating device for compressed air.
