Air diaphragm pump is a new type of mixing pump, which uses air compression as power device. The pneumatic diaphragm pump can be used to absorb light for all kinds of corrosive liquid, liquid with particles, low viscosity, volatile, flammable and toxic liquid. The paper describes the six advantages of the pneumatic diaphragm pump
1. Because of the driving power of gas, the total flow rate is adjusted automatically with the change of condensing type (friction resistance at inlet and outlet), and it is suitable for liquid with low viscosity. The working point of centrifugal pump is set up according to water standard. If the liquid with higher viscosity is used, it must be equipped with reducer or frequency converter, and the cost will be greatly improved, and the same for gear pump.
2. Pneumatic diaphragm pump is selected in the natural environment of inflammable materials, which is reliable and low-cost. For example, the transportation of natural materials, explosives and gunpowder is: first, it is unlikely to cause fire after grounding device; Second, there is no heat generated in the work, and the equipment is not easy to overtemperature; Third, liquid is not easy to over temperature because of the less stirring of liquid by pneumatic diaphragm pump.
3. In the construction site area, such as construction, industrial and mining enterprises' sewage discharge, because the waste water residue is many and complex, the pipeline is easy to block, so the submersible pump will be overloaded, and the motor will burn the vulnerable parts. The pneumatic diaphragm pump can be adjusted according to the particle and the total flow rate. When the pipeline is blocked, it will terminate to smooth automatically.
4. The external pneumatic diaphragm pump is small in shape and is not used for subgrade, occupying a small road surface, and simple and economic development of installation. It can be used as a moving raw material mixing pump.
5. In the solution of raw materials with bad influence and corrosion, the pneumatic diaphragm pump can completely separate the raw materials from the outside.
6. Pneumatic diaphragm pump can be used to transport the liquid with unstable physical properties, such as sensitive profile, inclined plate settling tank liquid, etc. This is due to the low shear stress of the pneumatic diaphragm pump, which has little physical harm to the raw materials.
The effect of pneumatic diaphragm pump in industrial production industry is very big. Many people can not make it manually, which can be indirectly carried out according to the pneumatic diaphragm pump to ensure the safety of the workers.
