Hydraulic diaphragm pump is a new type of liquid conveying equipment, which uses compressed air or nitrogen as the power source, through the principle of hydraulic diaphragm, the low pressure gas into high pressure membrane pump. Compared with other pumps, hydraulic diaphragm pump has the advantages of corrosion resistance, wear resistance, high temperature resistance and high reliability. It is widely used in liquid transportation and process control in chemical, food, electric power, metallurgy and other fields, and is known as "the ultimate choice of industrial fluid transportation". The working principle of the

hydraulic diaphragm pump is to use the movement of the diaphragm to transfer fluid, and there will be no pollution and leakage during the transportation process, which can greatly reduce the environmental pollution and production costs in the production process. Diaphragm pump is mainly composed of four parts: deflector, transmission mechanism, diaphragm box and diaphragm. Its working principle is as follows:

the action of the transmission mechanism of diaphragm pump, the deflector and compressed air form a back and forth movement, resulting in a change in the pressure in the diaphragm box, and the change of the pressure in the diaphragm box pushes the diaphragm to swing up and down and transport the fluid.

During the operation of the diaphragm pump, the diaphragm is separated from the upper and lower chambers of the fluid. At the same time, the transportation of the fluid is continuously completed between the two chambers of the diaphragm pump.

Finally, the delivery capacity of the diaphragm pump mainly depends on the size of the double chamber volume and the size of the pump head pressure output. When the output pressure of the pump is large, the same flow rate will increase the pressure in the diaphragm pump, which will affect the output effect of the pump.

hydraulic diaphragm pump is widely used in industrial production. It can accurately control the liquid volume transmission, is suitable for shock, paste, high viscosity, high solid content and chemical corrosion medium. It is not easy to block foreign matter, and the temperature range of the transmission medium is large. It can withstand chemical corrosion medium such as acid and alkali, salts, etc. Therefore, in many production and technological processes, diaphragm pump to replace the traditional centrifugal pump, piston pump, screw pump, gear pump and other traditional pumps.

technological innovation continues to promote the development of hydraulic diaphragm pumps, the market share of hydraulic diaphragm pumps continues to increase, and various new hydraulic diaphragm pumps continue to emerge, injecting new power and vitality into the development of various industries. We have reason to believe that hydraulic diaphragm pumps will become one of the representatives of domestic industrial high-end equipment and high-end technology in the new era of "three highs and one production doubling", in order to promote the high-quality development of China's industry and build China's manufacturing brand Contribute your own strength.
