The working part of diaphragm pump is mainly composed of crank connecting rod mechanism, plunger, hydraulic cylinder, diaphragm, pump body, suction valve and discharge valve. The driving mechanism composed of crankshaft, connecting rod, plunger and hydraulic cylinder is very similar to reciprocating plunger pump. Various industrial fields: it is suitable for the transportation of various high, medium and low viscosities, various acids, alkalis and corrosive fluids and various solvents in the chemical industry.

Application of explosion-proof electric diaphragm pump: it is used as the front pressure supply device of various filter presses. The main component of the explosion-proof electric diaphragm pump is the diaphragm explosion-proof. Precautions for the electric diaphragm pump. When the conveying liquid is a medium easy to precipitate and crystallize, it shall be cleaned and drained in time after use to avoid damage during re opening.

Before understanding the function of the electric diaphragm pump, you can first understand its characteristics. The advantage of the pump is that it overcomes the disadvantages of the traditional pump, uses the piston ring seal to replace the mechanical seal of the previous transportation equipment, and is immersed in the hydraulic oil throughout the operation process, which greatly reduces the friction and gives the diaphragm a stronger service life.

Corrosion resistance we all know that the diaphragm pump itself is produced to absorb liquids or substances of different media, so every machine with different materials should have corrosion resistance. Of course, the plastic diaphragm pump must also be able to resist corrosion, but its resistance to corrosion has reached an excellent level.

The cylinder head of the diaphragm pump is mainly separated from the working liquid by a diaphragm. When the diaphragm moves to one side of the transmission mechanism, the working chamber in the pump cylinder sucks liquid under negative pressure; It is applicable to the transportation of precious liquid, high-risk, harmful, highly corrosive and other dangerous materials. Because the pneumatic diaphragm pump has no dynamic sealing structure, it is completely separated from the outside and has no leakage.
