How to adjust the high pressure and low pressure of the pressure regulating valve of air compressor

How to adjust the pressure regulating valve of air compressor 1

The pressure regulating valve can only adjust the opening of the intake valve, but not the high and low pressures.

High and low pressure are adjusted by pressure switch (or controller). It's a square black box. Open the screw on it and take off the cover. There are two adjusting screws, 1 for increasing pressure and 1 for adjusting pressure band, i.e. low pressure. If the high pressure is 8 kg, the low pressure will be adjusted to 7 kg. Adjust according to the actual pressure required by the equipment. When adjusting, turn the screw left and right to know whether it is high or low.

How to adjust the pressure regulating valve of air compressor Method 2

There are two small screws! You can try a tune! One is the lowest pressure! One is to adjust the pressure difference!

Minimum pressure: this is the lowest starting pressure; Just say 0.6 to start! Pressure difference: for example, it is 0.4 now, and it starts at 0.6 and stops! You can turn it to 0.4, start it to 0.7, and stop it.

Pay attention to the method when you understand the tune! Remember to cut off the power immediately, it's safest! I remember that the lower one is to adjust the minimum working pressure, and the higher one is the maximum pressure!

Let the air compressor stop working first, (loosen the high one first) start to adjust the minimum pressure, and turn to start. Turn it up if you dare not! Let it work, almost to the highest pressure you need, you just have to relax the highest pressure and stop as soon as the pressure comes! No experience, don't be nervous, but be careful! Those are charged!
