Pneumatic diaphragm pump is currently the most novel kind of pump, it mainly uses compressed air as power source, is a new type of conveying machinery. So how does it work and at what occasion to play its role? Pneumatic diaphragm pump First, the working principle of pneumatic diaphragm pump 1, compressed air as the driving force. 2, is a volumetric displacement pump caused by reciprocating deformation of the diaphragm, its working principle is similar to the piston pump, the diaphragm pump has the following characteristics due to the working principle of the diaphragm pump: (1) diaphragm pump will not overheat : Compressed air as power, when the exhaust is an expansion heat absorption process, the temperature is reduced when the pneumatic pump work, no harmful gases discharged. (2) diaphragm pump will not produce spark: pneumatic diaphragm pump without electricity as power, grounding and then prevent the electrostatic spark (3) diaphragm pump can contain particles of liquid: because the volume of work and import for the ball valve, it is not easy to be Blocking. (4) membrane pump on the material shear force is extremely low: how to suck into the work how to spit it out, so the smallest material agitation for unstable material delivery (5) diaphragm pump flow can be adjusted at the material outlet At the installation of throttle to regulate the flow. (6) diaphragm pump has a self-priming function. (7) The diaphragm pump can be air operated without danger. (8) diaphragm pump can dive work. (9) Diaphragm pumps deliver a very wide range of fluids, from low viscosity to high viscosity, from corrosive to viscous. (10) diaphragm pump without complex control system, no cables, fuses and so on. (11) diaphragm pump small size, light weight, easy to move. (12) diaphragm pump without lubrication so easy maintenance, will not be due to drip leakage of work environment. (13) Diaphragm pumps are always efficient and will not be reduced by wear. (14) 100% energy use of the diaphragm pump, shut down the outlet, the pump automatically shut down, the device moves, wear, overload, fever (15) diaphragm pump without dynamic seal, easy maintenance to avoid leakage. No dead spots at work. Second, the application occasions 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 and explosive environment with pneumatic pump reliable and low cost, such as fuel, gunpowder, explosives, because: First, the ground is not likely to spark; second, no heat during work, the machine is not Will overheat; thirdly, the fluid will not overheat because the 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 complex composition, 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 diaphragm pump is small and 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 a hazardous, corrosive material handling, 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 diaphragm pumps have low shear forces and little physical impact on the material. Industrial Internet (Xiamen) Technology Co., Ltd.
