summarize
Aluminum alloy pneumatic diaphragm pump the whole pump body is made of aluminum alloy material, aluminum alloy material compared with other metal materials such as cast iron, stainless steel and so on, the main advantage is light weight, so it is more convenient to move in actual use. Good wear resistance when pumping mud medium. Because the diaphragm pump uses compressed air as the power, special structure and working principle, there is no rotating parts such as impeller and shaft seal in the pump, which is not only used in places requiring explosion-proof safety, but also good passing, and can avoid the leakage of the vane pump and the shortcomings of not allowing idling in operation. Especially suitable for conveying toxic and harmful, volatile, high viscosity, poor fluidity or corrosive media, not electric, safe and reliable in flammable and explosive places. It can be used as a submersible pump submerged in water. In many working conditions, it can replace sewage pump, liquid pump, pump, submersible pump, self-priming pump and other pump types.
Working principle
In the two symmetric working chambers of the aluminum alloy pneumatic diaphragm pump, each is equipped with a flexible diaphragm, and the two diaphragmes are formed into one, compressed air from the inlet joint of the pump, promotes the diaphragm in the two working chambers, and drives the two diaphragmes connected by the rod to move synchronously. At the same time, the gas in the other working chamber is discharged out of the pump from the back of the diaphragm. Once you reach the end of your journey. The valve mechanism automatically introduces compressed air into another working chamber, pushing the diaphragm in the opposite direction, so that the synchronous reciprocating motion of the two diaphragms is formed. Each working chamber is provided with two one-way ball valves, the reciprocating movement of the diaphragm, resulting in the change of the content of the working chamber, forcing the two one-way ball valves to open and close alternately, so that the liquid is continuously inhaled and discharged.
