Pneumatic diaphragm pump market development situation

11 - 13

pneumatic diaphragm pump market development survey of pneumatic diaphragm pump is a new type of conveying machinery, pneumatic diaphragm pump adopts compressed air as power source, for all kinds of corrosive liquid, with particles of liquid, high viscosity, volatile, flammable, poisonous liquid, it can be smoked light, has now formed the production, product quality, are welcome. The main characteristic of this kind of pump is without irrigation water diversion, both can flow pumping liquid, and can carry some is easy to flow medium, high, suction head is adjustable, 0 - 50 meters) Air pressure or work only more than 1 kg/cm2, absolutely for fire and explosion prevention, submersible pump, self-priming pump, all impurity pump, shield pump, slurry pump function, and many features of the conveying machinery. Pneumatic diaphragm pumps have the characteristics of the above. As a result, pneumatic diaphragm pump since birth is gradually invaded other pump market, and has a part of it. Such as: painting, ceramics in the pneumatic diaphragm pump has been occupies the absolute dominant position, and in some 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 is the one of the most innovative pump. USES the compressed gas as the power source, for all kinds of corruption and liquid, with particles of liquid, high viscosity, volatile, flammable, poisonous liquid, it can be smoked light. Pneumatic diaphragm pump has four kinds of material: plastic, aluminum, cast iron, stainless steel. Pneumatic diaphragm pump according to different liquid medium with nitrile butadiene rubber, chloroprene rubber, fluorine rubber, ptfe, poly vinyl hexagon. To meet the needs of different users. Housed in a variety of special occasions, for pumping of conventional pump can't suction medium, satisfactory results have been achieved. 1, due to the using gas as the power, so flow with back pressure ( Export resistance) The change and take the initiative to adjust, pneumatic diaphragm pump suitable for high viscosity fluid. And centrifugal pump working point due to the benchmark set in water, if slightly higher viscosity fluid, the necessary supporting reducer or VVVF inverter, the cost is greatly improved and the same about the gear pump. 2, in inflammable and explosive environment with pneumatic pump reliable and low cost, delivery, such as fuel, gunpowder, explosives because: first, after the ground could not produce sparks; Second, working in generating heat, the machine not overheating; Third, the fluid does not overheat because of pneumatic diaphragm pump on the fluid agitation is minimal. 3, in the middle of the site of the bad, such as building construction, industrial and mining waste water emission and the composition is complicated, because of the impurity in the sewage pipe is easy to attack, so the electric water pump to form high load environment, electrical heating vulnerability. Pneumatic diaphragm pump can be through the particles and the flow rate is adjustable, take the initiative to stop when pipeline infarction. 4, other pneumatic diaphragm pump small size is easy to move, do not need foundation, cover an area of an area small, simple and economic. can be used as a move type material. 5, in damaging, corrupt, materials handling, diaphragm pump materials can be completely isolated from the outside world. 6, or some experiments that there was no impurity pollution materials. 7, can be used for chemical properties relatively volatile liquid, such as: photographic materials, such as flocculation liquid. This is because the diaphragm pump shear stress is low, physical impact on the material. Pneumatic diaphragm pump is a kind of powered by compressed air, caused by deformation of diaphragm reciprocating volume change of positive displacement pump, its working principle is akin to plunger pump, because of the characteristic of the working principle of the pneumatic diaphragm pumps, pneumatic diaphragm pump has the following characteristics: ( 1) does not overheat: compressed air as the power, when the exhaust is an endothermic process of expansion, pneumatic pump when working temperature is lower, no harmful gas discharge. （ 2) Won't produce sparks: pneumatic diaphragm pump power, without power grounding and prevent the electrostatic spark ( 3) Can contain particles of liquid: for displacement and import work for ball valve, so it is not easy to be blocked. （ 4) Low shear force of material: how is sucked into how spit out at work, so minimal agitation of the material, is suitable for the unstable material conveying ( 5) Flow adjustable, can be in material with throttle valve to regulate traffic. （ 6) Has the function of self-priming. （ 7) Empty can run, but there is no danger. （ 8) Can diving. （ 9) Can conveying fluid is very broad, from low to high viscosity, viscosity sticky from corrosion. （ 10) No complicated control system, no cables, fuses, etc. （ 11) Small volume, light weight, easy to move. （ 12) Non-lubricated so maintenance is simple, not because the drip work environment pollution. （ 13) have always been able to maintain efficient, will not be reduced because of wear and tear. （ 14) One hundred percent of the energy use, when closed, export pump automatic stop, mobile equipment, wear, overload, fever, 15) No dynamic seal, simple maintenance to avoid the leakage. Work without dead center.
