Pneumatic diaphragm pump is a new type of conveying machinery, which uses compressed air as the power source. It can pump and absorb all kinds of corrosive liquids, liquids with particles, high viscosity, volatile, flammable and highly toxic liquids.
Pneumatic diaphragm pump is a new type of conveying machinery and a novel pump in China. Compressed air is used as the power source, which can be used for all kinds of corrosive liquids.
Pneumatic diaphragm pump has four materials: engineering plastic, aluminum alloy, stainless steel and cast iron. The pneumatic diaphragm pump adopts nitrile rubber, neoprene, fluororubber, polytetrafluoroethylene, polytetraethylene, etc. according to different liquid media to meet the needs of different users. It is placed on various special occasions to pump various media that cannot be pumped by conventional pumps, and satisfactory results have been achieved.
Because the pneumatic diaphragm pump has the above characteristics, the pneumatic diaphragm pump is gradually invading the market of other pumps and occupying a part of them since its birth. For example, pneumatic diaphragm pump has occupied a dominant position in painting and ceramics industry, while in some other industries, such as environmental protection, wastewater treatment, construction, sewage discharge and fine chemical industry, it is expanding its market share and has an irreplaceable position of other pumps.
Working principle and characteristics
Pneumatic diaphragm pump is a positive displacement pump driven by compressed air and caused by reciprocating deformation of diaphragm. Its working principle is similar to that of plunger pump. Due to the characteristics of working principle of pneumatic diaphragm pump, pneumatic diaphragm pump has the following characteristics:
1. The pump will not overheat: the compressed air is used as power, and the exhaust is an expansion and heat absorption process. When the pneumatic pump works, the temperature is reduced and no harmful gas is discharged.
2. No electric spark: the pneumatic diaphragm pump does not use electricity as power, and electrostatic spark is prevented after grounding.
3. It can pass the liquid containing particles: it is not easy to be blocked because of the positive displacement work and the inlet is a ball valve.
4. The shear force on materials is very low: how to suck in and spit out during work, so the stirring of materials is small, which is suitable for the transportation of unstable substances.
