Pneumatic double diaphragm pump was born, making a variety of corrosive liquids, high viscosity, volatile and other special substances can be timely and effective treatment. Pneumatic double diaphragm pump high-quality product assurance and work efficiency has been numerous acclaim, which is the pneumatic dual diaphragm pump based on the market an important factor. Pneumatic double diaphragm pump First, the pneumatic double diaphragm pump works: Pneumatic double diaphragm pump with compressed air, nitrogen or natural gas as a driving force. The main directional (pneumatic) control valve distributes compressed air to the gas chamber, applying uniform pressure to the inner surface of the diaphragm. At the same time, the discharged gas is discharged from the other side of the pump through the pilot port of the valve assembly. Pneumatic double diaphragm pump cavity gas pressure exceeds the pressure of the liquid chamber, the diaphragm connecting rod moves back and forth, emissions on one side, inhalation on the other side. The direction of discharge and aspiration of liquid is controlled by the direction of check valves (ball valves or sheet valves). Second, the pneumatic double diaphragm pump Features 1, pneumatic diaphragm pump will not produce sparks: pneumatic diaphragm pump power without electricity, grounding and then prevent the static spark. 2, will not overheat: Compressed air as a driving force, when the exhaust is an expansion of heat absorption process, the temperature is reduced pneumatic pump, no harmful gas discharge 3, can contain particles of liquid: Because the volume of work and import For the ball valve, so it is not easy to be blocked. Third, the pneumatic dual diaphragm pump applications occasions 1, due to the use of air as power, so the flow rate with the back pressure (outlet resistance) changes and automatically adjust, suitable for high viscosity 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. Through the above description of the working principle of the pneumatic double diaphragm pump, the characteristics of the pneumatic double diaphragm pump and the application of the pneumatic double diaphragm pump, the understanding of the pneumatic double diaphragm pump is even more profound. China has a huge pump demand market, with the recovery of the international community economy, the demand for the pump is also increasing, I believe double-diaphragm pneumatic pump for the development of the greater challenges and opportunities.
