Pneumatic diaphragm pump power is compressed air, it is currently used an innovative conveyor machinery, in our country is the most novel kind of pump.Pneumatic diaphragm pump which has four kinds of material composition : Plastic, aluminum, cast iron, stainless steel. Diaphragm pumps are based on different liquid medium were nitrile rubber, neoprene, fluorine rubber, PTFE, polyhexamethylene. To meet the needs of different users. Placed in a variety of special occasions, used to pump a conventional pump can not be aspirated medium, have achieved satisfactory results. What is the working principle of pneumatic diaphragm pump Next will analyze the working principle of pneumatic diaphragm pump: Pneumatic diaphragm pump using compressed air as the power source, is a pneumatic positive displacement self-priming pump, which is the latest in the domestic pump products A pump product, is a new type of conveyor machinery. The air is compressed into the back of the diaphragm via the air valve, squeezing the fluid chamber from the diaphragm. This air-driven approach eliminates the mechanical stress of typical piston drives, significantly extending the life of the diaphragm. When the compressed air pushes the diaphragm A away from the center body, the diaphragm at the other end is simultaneously pulled toward the central body by the connected central shaft. At this time, the air at the back of the diaphragm is discharged to the outside of the pump body through the outlet. This causes the chamber to be evacuated so that fluid can be pushed from the inlet manifold to the valve seat by the outside atmospheric pressure to allow fluid to freely enter the chamber until it is filled. When the air-squeezed diaphragm reaches its limit of displacement, the air valve guides the air to the back of the diaphragm and also creates a squeezing force that causes it to push away from the centerbody while pulling the attached diaphragm back to the centerbody, At this moment, the hydraulic pressure generated by the diaphragm drives the inlet valve ball back to the valve seat, and at the same time, the outlet valve ball is pushed away from the valve seat so that the fluid can be squeezed and discharged out of the pump body through the outlet. Diaphragm is pulled back to the center of the body This action makes the chamber into a vacuum state, which can rely on the role of atmospheric pressure fluid from the inlet manifold to push the valve ball from the valve seat into the A chamber until filled. The material is pumped out through horizontal motion of the two diaphragms fixed at both ends of the central shaft. In the left air chamber, compressed air is fed to move the center axis to the left. The material in the material chamber is pressed out while the material chamber sucks the material. When the center axis moves left to the end of the stroke, the air exchange valve is reversed and the compressed air is fed to the right air chamber to move the center axis to the right. The material in the material chamber is pressed out while the material chamber sucks the material. This action reciprocating material is continuously inhaled and discharged. Through the above introduction, we can know more clearly the working principle of pneumatic diaphragm pump. Pneumatic diaphragm pumps for such products, its future needs to face many difficulties, which not only requires the efforts of professionals also need all sectors of attention.
