Pneumatic diaphragm pump is a new type of conveying machinery, can transport all kinds of corrosive liquid, liquid with particles, high viscosity, volatile, flammable, highly toxic liquid. Pneumatic diaphragm pump has four materials: plastic, aluminum alloy, cast iron, stainless steel.
In the painting, ceramics industry pneumatic diaphragm pump has occupied a good dominant position, and in some other industries, such as environmental protection, wastewater treatment, construction, sewage, fine chemical industry is expanding its market share, and has the irreplaceable status of other pumps. The advantages of pneumatic diaphragm pump are:
1, can be used to transport chemical properties of relatively unstable fluid, such as: photosensitive materials, flocculant, etc. This is because of the low shear force of the pneumatic diaphragm pump, the physical impact of the material is small.
2. In the treatment of hazardous and corrosive materials, pneumatic diaphragm pump can completely separate the materials from the outside world.
3, or some tests to ensure that there is no impurity pollution of raw materials.
4, due to the use of air for power, so the flow with the change of back pressure (outlet resistance) and automatic adjustment, suitable for high viscosity fluid. And the working point of the centrifugal pump is set on the basis of water. If it is used for the fluid with slightly higher viscosity, it needs to support the reducer or frequency conversion governor. The cost is greatly increased, and the same is true for the gear pump.
5, in flammable and explosive environment with pneumatic pump reliable and low cost, such as fuel, gunpowder, because: after grounding can not produce sparks; Second, no heat generation in the work, the machine will not overheat; Third, the fluid will not overheat because the agitation of the fluid is minimal.
6, in the site of bad places, such as construction sites, industrial and mining waste water discharge, due to the impurities in the sewage and complex composition, pipeline is easy to plug, so that the electric pump will form too high load, motor heating vulnerable. Pneumatic diaphragm pump can pass through the particles and flow adjustable, pipe blocking automatically stop to unobstructed.
In addition, pneumatic diaphragm pump small volume is easy to move, do not need the ground, occupying very small, easy and economical installation. Can be used as mobile material transfer pump.
