Hai Xing (Lai Zhou city) Mechanism Manufacture Factory, is

In the procedure of air charge, the compressed air from air compressor through interface 1 to the chamber 2. Because of temperature down, condensate water is made, the condensate water through passway 3 to the valve 4. From filter 13 and round chamber, the compressed air reaches the upper end of dry canister 15. When airflow passes dryer 14, moisture is absorbed and stays at upper layer of dryer canister. The dried air passes single way valve 12, interface 21 to 4 loops protect valve , then provided to air circuit of whole vehicle. At same time, the dried air passes throttle holes 11, interface 22 to regeneration air storage canister. When the air pressure in the whole system raises to the prepared values, compressed air push piston 7 to move, open valve 8, close valve 10, compressed air pass way 6 to the upper end of piston 5, pushes piston 5 to down move, make the valve 4 open, the compressed air and condensate water from chamber 2 pass opened exhaust valve 4 to atmosphere, start exhaust procedure. At same time of exhaust, clean air from regeneration storage canister passes open 22 into dryer, to throttle hole 11, dryer canister 15, chamber 2 and exhaust valve 4 to atmosphere. When air from down to up flow through powder dryer, take away all moisture on the surface, exhaust it to atmosphere, make regeneration and activation to dryer. When the pressure of main air circuit connecting to open 21 downs to working pressure value, piston 8 move at operation of position back spring, valve 7 closed, valve 10 open. Valve 5 move to up, valve 4 close, finish the procedure of exhaust, so next air charge procedure is on. By screw 9 to adjust down load air pressure value and pressure value to close. The air dryer equipped with automatic heater, to avoid frozen of piston, and working barrier.
