Plastic pneumatic diaphragm pump can realize the automatic adjustment of flow mode

Plastic pneumatic diaphragm pump is a kind of conveying machinery, is a kind of pump in China, using compressed air as power source, for all kinds of corrosive liquids can be used.

Pneumatic diaphragm pump has four kinds of materials: engineering plastics, aluminum alloy, stainless steel, alloy, according to different liquid media respectively using nitrile rubber, neoprene rubber, fluorine rubber, PTFE, PTFE, PTFE, etc., to meet the needs of different users. Placed in a variety of special occasions, used to pump a variety of conventional pump can not pump the medium, have achieved satisfactory results. It takes the static seal to lead the dynamic seal, to realize the isolation of the internal and external environment, will not cause the leakage of corrosive and viscous substances, to protect the personal safety of the operator.

Diaphragm pump is a kind of transportation equipment, it is in the pump body of the symmetrical part of the placement of a diaphragm and connecting rod as the basic structure, its outstanding technology research and development advantages are: The operation mode is simplified, the safety performance is improved, the operating system is improved, the throttle valve is used to automatically adjust the flow mode, and the fuse and cable are no longer used, and the hidden danger of excessive temperature of the pump caused by electric spark is reduced. Improved seal standards prevent the risk of leakage.

Working principle In the two symmetric working chamber, each equipped with a piece of elastic diaphragm, the rod will be two diaphragm into one body, compressed air from the pump inlet joint into the valve, promote the diaphragm in the two working chamber, drive the rod connected two diaphragm synchronous movement. At the same time, the gas in the other chamber is discharged from the pump through the back of the diaphragm. Once the end of the stroke is reached, the valve mechanism automatically introduces compressed air into the other working chamber, pushing 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 motion of the diaphragm causes the change of the content of the working chamber, forcing the two one-way ball valves to open and close alternately, so as to continuously inhale and discharge the liquid.
