Pneumatic diaphragm pump is a new type of transport machinery, using compressed air as the power source, for all kinds of corrosive liquid, liquid with particles, high viscosity, volatile, flammable, highly toxic liquid, can be pumped up.
Pneumatic diaphragm pump is a new type of conveying machinery, which is a new type of pump in China. Using compressed air as power source, it can be used for all kinds of corrosive liquids.
Pneumatic diaphragm pump has four kinds of materials: engineering plastics, aluminum alloy, stainless steel, cast iron. According to different liquid medium, pneumatic diaphragm pump adopts nitrile rubber, chloroprene rubber, fluororubber, polytetrafluoroethylene, polytetrafluoroethylene, etc. to meet the needs of different users. It is installed in various special occasions to pump media that can not 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, the pneumatic diaphragm pump has occupied a dominant position in the painting and ceramic industry, while in some other industries, such as environmental protection, wastewater treatment, construction, sewage, fine chemical industry, it is expanding its market share, and has an irreplaceable position in other pumps.
Pneumatic diaphragm pump has four kinds of materials: plastic, aluminum alloy, cast iron, stainless steel. Pneumatic diaphragm pump adopts NBR, chloroprene rubber, fluororubber, polytetrafluoroethylene and polytetrafluoroethylene according to different liquid medium. To meet the needs of different users. It is installed in various special occasions to pump media that can not be pumped by conventional pumps, and satisfactory results have been achieved.
1. Because the gas is used as power, the flow rate is adjusted actively with the change of back pressure (outlet resistance), which is suitable for medium and high viscosity fluids. Because the working point of centrifugal pump is set based on water, if it is used for the fluid with slightly higher viscosity, it must be equipped with reducer or frequency converter, so the cost is greatly increased, and the same is true for gear pump.
2. In flammable and explosive environment, pneumatic pump is reliable and low cost, such as the transportation of fuel, gunpowder and explosive
First, it is impossible to produce sparks after grounding;
Second, there is no heat generated in the work, and the machine will not overheat;
Third, the fluid will not overheat, because the pneumatic diaphragm pump on the fluid agitation small.
3. In the bad center of the construction site, such as the construction site, industrial and mining wastewater discharge, due to the impurities in the sewage and complex composition, the pipeline is easy to block, so the electric pump will form a high load environment, and the motor will heat easily. The pneumatic diaphragm pump can pass through particles and the flow rate is adjustable. It will stop when the pipeline is blocked.
4. In addition, the pneumatic diaphragm pump is small, easy to move, does not need foundation, occupies a small area, and is easy to install and economical. It can be used as mobile material delivery pump.
5. In the treatment of hazardous and corrosive materials, the diaphragm pump can completely isolate the materials from the outside world.
6. Or some experiments to ensure that there is no impurity pollution of raw materials.
7. It can be used to transport fluid with unstable chemical properties, such as photosensitive material, flocculant, etc. This is because the diaphragm pump shear force is low, the physical impact on the material is small.
