Aluminum diaphragm pump works: In the diaphragm pump two symmetrical working chamber, each fitted with a flexible diaphragm, the link will be two pieces of diaphragm into one, the compressed air from the pump inlet into the valve After the two working chamber to promote the diaphragm, drive the two rods connected to the linkage rod synchronized movement. At the same time, the gas in the other working chamber is drained from the back of the diaphragm out of the pump. Once you reach the end of the itinerary. The air distribution mechanism automatically introduces compressed air into the other working chamber to push the diaphragm in the opposite direction, thus forming a synchronous reciprocating motion of the two diaphragms. Each working chamber is provided with two one-way ball valves, the reciprocating movement of the diaphragm causing a change in the volume of the working chamber, forcing the two one-way ball valves to alternately open and close, thereby continuously drawing and discharging the liquid.
