Working principle and characteristics of pneumatic diaphragm pump

Pneumatic diaphragm pump is a kind of compressed air as the power, by the diaphragm reciprocating deformation caused by the volume change of the positive displacement pump, its working principle is similar to the plunger pump, due to the characteristics of the working principle of the pneumatic diaphragm pump, so the pneumatic diaphragm pump has the following characteristics:

(1) The pump will not overheat: compressed air for power, in the exhaust is an expansion heat absorption process, the temperature is reduced when the pneumatic pump is working, no harmful gas discharge.

(2) No electrical spark: the pneumatic diaphragm pump does not use electricity for power, and prevents electrostatic sparks after grounding.

(3) Liquid containing particles can be passed: because of the positive displacement work and the inlet is a ball valve, it is not easy to be blocked.

(4) The shear force on the material is very low: how to suck in and spit out when working, so the agitation of the material is minimal, which is suitable for the transport of unstable substances.

(5) The flow can be adjusted, and a throttle valve can be installed at the outlet of the material to adjust the flow.

(6) Has the function of self-priming.

(7) Can be run empty, without danger.

(8) Can dive work.

(9) A wide range of fluids can be transported, from low viscosity to high viscosity, from corrosive to viscous.

(10) No complex control system, no cables, fuses, etc.

(11) Small size, light weight, easy to move.

(12) No lubrication is required, so the maintenance is simple and will not pollute the working environment due to drip.

(13) The pump can always remain efficient and will not be reduced by wear.

(14) 100% energy utilization, when the outlet is closed, the pump automatically stops, there is no equipment movement, wear, overload, heat.

(15) No dynamic seal, easy maintenance to avoid leakage, no dead point during work.
