How does the rubber diaphragm work?

Rubber die is also called rubber diaphragm, rubber valve, etc. I believe that many people in the industry are not unfamiliar. This kind of rubber product that has been widely used in various water pumps, air pumps, valves and other equipment has "it". So do you know all about how it works? Today, Yongyong Silicone Rubber will tell you how one of the rubber diaphragms used in water pumps and air pumps works efficiently.

Diaphragm pump is a special form of positive displacement pump. It relies on the back-and-forth agitation of a rubber diaphragm to change the volume of the working chamber to inhale and discharge the liquid. The pneumatic diaphragm pump is mainly composed of the transmission part and the diaphragm cylinder head. The transmission part is a driving mechanism that drives the diaphragm to agitate back and forth. Its transmission forms include mechanical transmission, hydraulic transmission and pneumatic transmission, among which hydraulic transmission is widely used. The working part of the diaphragm pump is mainly composed of crank connecting rod mechanism, plunger, liquid cylinder, diaphragm, pump body, suction valve and discharge valve, etc. Among them, the driving mechanism composed of crankshaft connecting rod, plunger and liquid cylinder and the reciprocating column Plug pumps are very similar.

When the diaphragm pump is working, the crank connecting rod mechanism drives the plunger to reciprocate under the drive of the motor, and the movement of the plunger is transmitted to the diaphragm through the working liquid (usually oil) in the liquid cylinder, so that the diaphragm is agitated back and forth.

The cylinder head part of the pneumatic diaphragm pump is mainly separated by a diaphragm to separate the conveyed liquid and the working liquid. When the diaphragm moves to one side of the transmission mechanism, the pump cylinder is under negative pressure and sucks the liquid when the diaphragm moves to the other side. , the liquid is discharged. The liquid to be conveyed is separated from the working liquid by the diaphragm in the pump cylinder, and only contacts with the pump cylinder, the suction valve, the discharge valve and the inner side of the diaphragm, and does not contact the plunger and the sealing device, which makes the column Important parts such as plugs work completely in the oil medium and are in good working condition.
