Pneumatic diaphragm pump is a new type of conveying machinery, 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 , Has now formed a production, product quality acclaimed. The main features of this pump is not need to fill the water, both to move the liquid flow, but also transport some easy to flow medium, suction lift, head adjustable (0-50 m) air pressure only greater than 1kg / cm2 that can work, absolutely fire and explosion, with submersible pumps, self-priming pumps, impurity pumps, shielded pumps, mud pump and conveying all the features of many features. Pneumatic diaphragm pump Overview: 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. Pneumatic diaphragm pump has four kinds of materials: engineering plastics, aluminum, cast iron, stainless steel. Pneumatic diaphragm pumps are based on different liquid media were nitrile rubber, neoprene, fluorine rubber, PTFE, polyhexamethylene. To meet the needs of different users. Placed in a variety of special occasions, used to pump a conventional pump can not be aspirated medium, have achieved satisfactory results. Pneumatic diaphragm pump applications: As the pneumatic diaphragm pump has the above characteristics, so in the world since the birth of pneumatic diaphragm pumps are gradually invaded other pump market, and take up some of them. Such as: paint, ceramic diaphragm pump has occupy an absolute dominance, while in other industries, such as environmental protection, wastewater treatment, construction, sewage, fine chemicals is expanding its market share and have other pumps Alternative status. Pneumatic diaphragm pump advantages: 1, due to the use of air as power, so the flow rate with the back pressure (outlet resistance) changes automatically adjusted for the viscosity of the 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, in a flammable environment with pneumatic pump reliable and low cost, such as fuel, huoyao, zhayao the delivery, because: First, the ground is not likely to produce sparks; second, no heat during work, the machine is not Will overheat; Third, the fluid will not overheat because the pneumatic 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 the hazardous, corrosive materials handling, pneumatic diaphragm pump can be completely separated from the outside world. 6, or some experiments to ensure that no impurities pollute the raw materials. 7, can be used to transport the chemical properties of relatively unstable fluids, such as: photographic materials, flocculation and so on. This is because the pneumatic diaphragm pumps have low shear forces and have a small physical impact on the material. Pneumatic diaphragm pump works: 1, compressed air as the driving force. 2, Features Pneumatic diaphragm pump is a volumetric displacement pump caused by the reciprocating deformation of the diaphragm. Its working principle is similar to the piston pump. Because of the working principle of the pneumatic diaphragm pump, the pneumatic diaphragm pump has the following features: (1) Pump will not overheat: compressed air as a driving force, when the exhaust is an expansion of heat absorption process, the temperature is reduced when the pneumatic pump work, no harmful gases discharged. (2) does not produce spark: pneumatic diaphragm pump without electricity as power, grounding and then prevent the static spark (3) can contain particles of liquid: because the volume of work and imports for the ball valve, so it is not easy to be blocked. (4) Extremely low shear force on the material: How to suck in the work and how to spit it out, so the material agitation is minimal, which is suitable for the transportation of unstable substances (5) The flow rate can be adjusted, and the section can be installed at the exit of the material Flow valve to regulate flow. (6) Self-priming function. (7) Can be air operated without danger. (8) can dive work. (9) The fluids that can be delivered are extremely wide, ranging from low viscosity to high viscosity, from corrosive to viscous. (10) There is no complicated control system, no cables, fuses and so on. (11) small size, light weight, easy to move. (12) Maintenance is easy without lubrication, and will not pollute the work environment due to drip. (13) The pump is always efficient and will not be reduced by wear. (14) 100% energy utilization, shut down the outlet, the pump automatically shut down, the device moves, wear, overload, fever (15) no dynamic seal, easy maintenance to avoid leakage. No dead spots at work
