Pressure regulator tuning spend unloading pressure adjusting screw for adjusting the air compressor, the rotary bolt clockwise Qingdao air compressor unloading pressure increase, counterclockwise rotation unload pressure is reduced. The tube cooler cooler air compressor maintenance, pay special attention to the outer surface depends on clean air compressor manufacturers, otherwise it will reduce the cooling effect and should therefore be based on the working conditions, regular cleaning tank / oil separator tank / oil separator according to standard pressure vessel fabrication and inspection, shall be arbitrarily modified, if you modify the consequences will be very serious adjustment follows a Remove the cap and seal;.. b If the valve is opened prematurely, loosen the lock nut and Tighten bolts semi-circle, if the valve open too late then loosen the lock nut about a lap and a half laps loosen bolts. c. Repeat detection step, if the safety valve when a predetermined pressure value, is still not open, then adjust it again.
