The principle of pneumatic diaphragm pump and what are the applicable occasions

pneumatic diaphragm pump is a new type of conveying machinery is the one of the most innovative pump. Pneumatic diaphragm pump adopts compressed air as power source for all kinds of corrosive liquid, with particles of liquid, high viscosity, volatile, highly poisonous liquid can be smoked light. There are four pneumatic diaphragm pump its material: plastic diaphragm pump, stainless steel, cast iron, aluminum alloy diaphragm pump diaphragm pump. Pneumatic diaphragm pump according to different liquid medium with nitrile butadiene rubber, butyl rubber, rubber, ptfe ethylene, poly vinyl allocation to meet the needs of different users. Housed in a variety of special occasions cannot be used for pumping of conventional pump suction medium were satisfactory results have been achieved.
a, applicable occasions of diaphragm pump
the pneumatic diaphragm pumps have the characteristics of the above so pneumatic diaphragm pump in the world since birth is gradually invaded other market and occupy a part of the pump. Such as painting, ceramics in the diaphragm pump has been occupies the absolute dominant position, and in other industries like environmental protection, wastewater treatment, construction, sewage, fine chemical is expanding its market share and can not be replaced with other pump status.
pneumatic diaphragm pump's advantage lies in:
, the pneumatic diaphragm pump with air power, so flow with back pressure ( Export of the change of the resistance automatically adjust suitable for high viscosity fluid. The centrifugal pump is a working point of water as a benchmark set, if used in a slightly higher viscosity fluid requires supporting reducer or VVVF inverter cost is greatly raised, the gear pump is the same.
pneumatic diaphragm pump, in inflammable and explosive environment reliable and low cost such as fuel delivery, first, after the ground could not produce sparks; Second, the work of generating heat machine not overheating; Third, the fluid does not overheat because the diaphragm pump on the fluid agitation is minimal.
, the site of bad places such as construction sites, industrial and mining waste water discharge, as the complicated ingredients and impurities in the sewage pipe is easy to jam, so the electric pump to form high load of electrical heating vulnerability. Pneumatic diaphragm pump can be through the particles and flow adjustable pipe jams for automatic stop to open.
and other pneumatic diaphragm pump small size is easy to move, don't need a foundation, take up little tiny, installation simple and economic. Can be used as mobile conveying pump.
, the damaging, corrosive materials processing of pneumatic diaphragm pump material can be completely separated with the outside world or some trial that there was no impurity pollution materials.
and can be used for chemical properties relatively volatile liquid such as sensitive material, such as flocculation liquid. This is because the low shear force of pneumatic diaphragm pump, physical impact on the material.
