1. The principle of working principle of pneumatic diaphragm pump

After the pneumatic diaphragm pump is connected to the compressed air, the air valve controls the compressed air to drive the film 1 to the right. At the same time, the membrane will squeeze the medium in the right membrane chamber to discharge the medium out of the pump cavity. The membrane not only plays the role of conveying medium, but also isolation and compressed air and medium in the pneumatic diaphragm pump cavity.

When a membrane is pushed away from the intermediate compressed air, at the same time, another membrane linking through the link link to the intermediate = in it = in it, the link in the high pressure is connected to the two mold chambers in the two mold chambers. Film. When the diaphragm 2 moves to the intermediate, the high -pressure air behind the membrane is forced to discharge to the outside world through the viaing direction of the valve.

When the diaphragm 2 moves to the intermediate air valve, the pneumatic diaphragm pump entrance occurs in vacuum and the import of the medium pump was pressed by atmospheric pressure. At this time, the import valve ball of the pneumatic diaphragm pump will be raised and leaves the valve seat, ensuring that the medium is easily charged in the eight pump cavity through the imported pipeline.

3. Performance characteristics of pneumatic diaphragm pump

1) Pumps will not be overheated: compressing the air for power. When exhausting, it is a process of expanding heat and absorbing heat. The temperature is reduced during the working of the pump and no harmful gas is discharged.

2) Electric sparks will not be generated: the pneumatic diaphragm pump does not use power for power, and the static spark is prevented after grounding.

3) It can be passed through particle liquid: because of the volume work and imported as the ball valve, it is not easy to be blocked.

4) The shear force of the material is extremely low: how to suck in how to spit it out during work, so the mix of the material is the minimum, and it is suitable for the transmission of unstable substances.

5) The flow can be adjusted, and the throttle valve can be installed at the material exit to adjust the flow.

6) Has the function of self -priming.

7) It can run empty without danger.

8) Diving work.

9) The fluid that can be transported is extremely wide, from low viscosity to high viscosity, and obtained viscosity from corrosiveness.

10) There are no complex control systems, no cables, fuses, etc.

11) Small volume, light weight, easy to move.

12) The maintenance is simple without lubrication, and it will not contaminate the working environment due to leakage.

13) Pumps can always remain efficient and will not be reduced due to wear.

14) 100 % energy use, when the exit is closed, the pump is automatically stopped, the equipment moves, wear, overload, and heat.

15) There is no dynamic seal, and the maintenance is easy to avoid leakage. There is no death point at work.
