Pneumatic diaphragm pump is a new type of conveying machinery, is currently the most novel kind of pump. The use of compressed air as the power source, for a variety of corrosive liquids, with particles of liquid, high viscosity, volatile, flammable, highly toxic liquid can be smoked exhausted. This article describes the pneumatic diaphragm pump in the field of practical 6:
1, due to the use of air as the power, so the flow rate with the back pressure (outlet resistance) changes and automatically adjust, suitable for medium and high viscosity fluid. Centrifugal pump operating point is set on the basis of water, if used for slightly higher viscosity fluid, you need to support reducer or inverter, the cost has greatly improved, the same is true of the gear pump.
2, pneumatic diaphragm pump in a flammable environment with pneumatic pump reliable and low cost, such as fuel, gunpowder, explosives delivery, because: First, the ground is not likely to spark; second, no heat generated during work , The machine will not overheat; Third, the fluid will not overheat because the diaphragm pump agitates the fluid to a minimum.
3, poor construction sites, such as construction sites, industrial and mining wastewater discharge, due to the impurities in the sewage and the composition of complex, easy to plug the pipeline, so the formation of the pump on the load is too high, the motor heat vulnerable. Pneumatic diaphragm pump through the particles and the flow rate can be adjusted, the pipeline automatically stop blocked to patency.
4, the other small pneumatic diaphragm pump easy to move, do not need the foundation, accounting for the ground is extremely small, easy and economical installation. Can be used as mobile material transfer pump.
5, in a hazardous, corrosive material handling, diaphragm pump can be completely separated from the outside world.
6, pneumatic diaphragm pump can be used to transport more unstable chemical properties of fluids, such as: photographic materials, such as flocculation. This is because diaphragm pumps have low shear forces and little physical impact on the material.
Pneumatic diaphragm pump in the role of industry is huge, and many difficult to human hand can be completed by the pneumatic diaphragm pump to indirectly ensure the safety of employees.
