After the door body of non-pressure air door or coal mine single air door is installed, the full pneumatic automatic control system device can be installed. First, hang the pneumatic control box and the pneumatic button box on the proper position of the roadway wall with expansion screws, then connect the front and rear ends of the cylinder with the pneumatic connectors corresponding to the pneumatic control box, and push all the push rods of the cylinder into the cylinder barrel (before adjusting the access end of the cylinder and the full pneumatic control system, do not butt the cylinder with the door leaf balance connecting rod of the pneumatic airless door). Connect the air source to the inlet of the oil-water separator in the air control box (before connecting the air source, the air pressure regulating device of the oil-water separator should be set to zero), and then slowly rotate and adjust the pressure regulating device of the oil-water separator. Jinan Dongshan often adjusts the pressure of the whole pneumatic automatic control system to 0.5-0.8MPa (the air pressure is greater than 0.8MPa, which is unsafe after exceeding the rated air pressure of pneumatic components; Not too small, less than 0.5MPa may not be able to throttle or unstable operation); From small to large, slowly adjust the pneumatic mechanical pressure valve at the inlet and outlet of the cylinder, carry out the simulation experiment of air door opening and closing, and test whether the inlet and outlet of the cylinder push rod meet the technical parameters set by the manufacturer. If yes, turn off the air pressure. Jinan Dongshan connected the push rod of the cylinder with the door leaf connecting rod of the mine air door, and the rear end of the cylinder was connected with the fixed bracket of the door frame, and then the air pressure was turned on again to carry out the automatic operation experiment of the real pneumatic airless door. If the switching speed of pneumatic valveless valve does not meet the requirements, it can be adjusted by air pressure regulating valve until
