In the two symmetrical working chambers of diaphragm pump, there is a piece of elastic diaphragm respectively, and the connecting rod will form two diaphragms into one. After the compressed air enters the air valve chamber from the air inlet connector of the pump, it pushes the diaphragm in a working chamber and drives the diaphragm connected by the connecting rod to move synchronously. At the same time, the gas in the other working chamber is discharged from the back of its diaphragm. When the piston reaches the end of stroke, the valve mechanism will automatically introduce compressed air into another working chamber to push the diaphragm pump to move in the opposite direction, thus forming the synchronous reciprocating motion of the two diaphragms. Each working chamber is equipped with two ball valves. The reciprocating motion of diaphragm causes the change of volume in the working chamber, forcing the two ball valves to open and close alternately, so that the liquid can be continuously inhaled and discharged.
