Pneumatic diaphragm pump advantages and scope of adaptation:
Diaphragm pump is a new type of conveying machinery, which can transport a variety of corrosive liquids, liquids with particles, high viscosity, volatile, flammable and highly toxic liquids. Diaphragm pump has four materials: plastic, aluminum alloy, cast iron, stainless steel. Diaphragm pump according to different liquid media respectively using butadiene rubber, neoprene rubber, fluorine rubber, polytetrafluoroethylene, polytetrafluoroethylene. To meet the needs of different users. Placed in a variety of special occasions, used to pump a kind of conventional pump can not pump the medium, have achieved satisfactory results. In the painting, ceramics industry diaphragm pump has occupied an absolute dominant position, the advantages of pneumatic diaphragm pump is:
1, because the air is used as the power, the flow rate is automatically adjusted with the change of back pressure (outlet resistance), which is suitable for medium and high viscosity fluids. In flammable and explosive environment, the pneumatic pump is reliable and low cost, such as the transmission of fuel, gunpowder, explosives, because: first, it is impossible to produce sparks after grounding; Second, no heat is generated in the work, and the machine will not overheat; Third, the fluid will not overheat because the diaphragm pump has minimal agitation for the fluid.
2, in the harsh place of the site, such as construction sites, industrial and mining waste water discharge, due to the impurities in the sewage and complex composition, the pipeline is easy to block, so that the electric pump will form an excessive load, the motor heating is vulnerable. The pneumatic diaphragm pump can pass through the particle and the flow rate is adjustable, and automatically stops to smooth when the pipeline is blocked.
3, can be used to transport chemical properties of relatively unstable fluid, such as: photosensitive materials, flocculant, etc. This is because the shear force of the diaphragm pump is low and the physical impact on the material is small.
4, in hazardous, corrosive material processing, diaphragm pump can completely separate the material from the outside world. 6, or some tests to ensure that there is no impurity pollution of raw materials. In addition, the diaphragm pump is small and easy to move, does not require foundation, occupies very little ground, and is simple and economical to install. Can be used as mobile material transfer pump.
Because the air is used as the power, the flow rate is automatically 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 on the basis of water, if it is used for fluids with slightly higher viscosity, you need to support the reducer or variable frequency governor, the cost is greatly increased, and the same is true for the gear pump.
