The main applications of air diaphragm pumps The air diaphragm pump is a new type of conveying machinery, which is a novel type of pump in China. Using compressed gas as the power source, all kinds of corrosive liquids, liquids with particles, high-viscosity, volatile, flammable, and highly toxic liquids can be exhausted. The pneumatic diaphragm pump has four materials: plastic, aluminum alloy, cast iron, and stainless steel. The pneumatic diaphragm pump uses nitrile rubber, chloroprene rubber, fluorine rubber, polytetrafluoroethylene, polyhexaethylene according to different liquid media. To meet the needs of different users. Placed in various special occasions, it is used to pump a kind of medium that cannot be pumped by conventional pumps, and has achieved satisfactory results. 1. Since air is used as power, the flow rate is actively adjusted with the change of back pressure (outlet resistance), which is suitable for medium and high viscosity fluids. The working point of the centrifugal pump is set based on water. If it is used for a fluid with a higher viscosity, a reducer or a frequency converter is necessary, and the cost is greatly improved. The same is true for gear pumps. 2. In the treatment of hazardous and corrosive materials, the diaphragm pump can completely separate the materials from the outside world. 3. The pneumatic diaphragm pump can be used in occasions where the medium is not expected to be contaminated. 4. The pneumatic diaphragm pump can be used to transport fluids with relatively unstable chemical properties, such as photosensitive materials, flocculants, etc. This is because the shear force of the diaphragm pump is low and the physical impact on the material is small. 5. It is reliable and low-cost to use pneumatic pumps in flammable and explosive environments, such as the transportation of fuel, gunpowder and other media, because: first, no sparks can be generated after grounding; second, no heat is generated during work, and the machine is not Will overheat; third, the fluid will not overheat because the pneumatic diaphragm pump agitates the fluid less. 6. In the harsh center of the construction site, such as construction site, industrial and mining wastewater discharge, due to the large amount of impurities and large components in the sewage, the pipeline is easy to be blocked, which creates an environment with excessive load on the electric pump, and the motor is easily damaged by heat. The pneumatic diaphragm pump can pass particles and the flow is adjustable, and the pipeline can be actively prevented to hysteresis when the pipeline is blocked. 7. Other pneumatic diaphragm pumps are small in size, easy to move, unnecessary foundation, small footprint, easy and economical placement. Can be used as a mobile material delivery pump.
