Sub-categorized analysis of the working principle of pneumatic diaphragm pump


1, compressed air as power.

2, is a volumetric displacement pump caused by the 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) the pump will not overheat: compressed air as a driving force, when the exhaust is an expansion heat absorption process, pneumatic pump temperature is reduced, no harmful gas emissions.

(2) does not produce sparks: pneumatic diaphragm pump without electricity as a motive force, grounding and then prevent the static spark

(3) can contain particles of liquid: Because of 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 and how to spit out when working, so the material agitation is minimal, which is suitable for the transportation of unstable materials

(5) flow rate can be adjusted at the exit of the material to install a throttle to regulate the 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) One hundred percent energy utilization, when shutting down the outlet, the pump stops automatically, the equipment is moving, worn, overloaded, feverish

(15) There is no dynamic seal, easy maintenance to avoid leakage. No dead spots at work.
