2) The air quantity regulation system (referring to the above control system) if the customer uses
the air quantity of the system is smaller than the air supply quantity of the air compressor, then the
air quantity regulation system can automatically adjust the air supply quantity of the air compressor.
①
Set the pressure of the pressure stabilizer valve makes the system before the pressure rise to
reduce the load pressure, a small amount of air will enter the servo cylinder of the intake valve
through the steady pressure valve to push the butterfly valve, and begin to adjust the air volume.
The setting pressure of the pressure-stabilized valve can be determined by the air volume used in
the field.
②
If the air volume is adjusted, the locking nut of the steady pressure valve will be loosened, the
counterclockwise rotation of the handle of the steady pressure valve will reduce the setting pressure,
and the clockwise rotation will increase the set pressure. After setting, tighten the lock nut.
③
If you do not need to adjust the volume of air, you can turn the steady pressure valve
clockwise to the limit and lock it.
6.4 Adjustment of safety valves
The discharge pressure of the relief valve is generally set to be higher than the exhaust pressure
of 0.1 Mpa. It has been adjusted well before leaving the factory, so it is not necessary to readjust it.
If you have to adjust the exhaust pressure of the relief valve for other reasons, you can relax the
locking nut above the relief valve, and then adjust the adjustment screw. If you rotate clockwise,
the exhaust pressure will increase, and the pressure set will decrease if you rotate counterclockwise.
After setting the discharge pressure, tighten the locking nut.
6.5 Replacement steps of oil separator
1) After the air compressor stops, the air outlet is closed and the drain valve is opened to confirm
that the system is free of pressure.
2) Disconnect the pipeline above the oil barrel and remove the pressure maintenance valve outlet
to the cooler.
3) Remove the fixing bolts above the oil and gas barrel.
4) Take away the upper cover of the oil and gas barrel and expose all the filter elements on the
barrel body.
