AODD pump working principle and characteristics

AODD pump is a kind of compressed air as the power, the diaphragm reciprocating deformation caused by the volume change of the positive displacement pump, its working principle is similar to the plunger pump, because of the characteristics of Air operated diaphragm pumps working principle, so pneumatic diaphragm pump has the following characteristics:
(1) the pump will not overheat: compressed air for power, in the exhaust is an expansion of the process of heat absorption, pneumatic pump working temperature is reduced, no harmful gas discharge.
(2) no electrical spark: pneumatic diaphragm pump does not use electricity for power, after grounding and prevent electrostatic sparks.
(3) Can pass through the liquid containing particles: because of the positive displacement and the inlet is a ball valve, so it is not easy to be blocked.
(4) very low shear force on the material: working is how to suck in how to spit, so the agitation of the material is minimal, suitable for the transport of unstable material.
(5) The flow can be adjusted, and the throttle valve can be installed at the outlet of the material to adjust the flow.
(6) With the function of self-priming.
(7) can be empty operation, 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 so easy maintenance, will not pollute the working environment due to drip.
(13) The pump can always maintain high efficiency, will not be reduced because of wear.
(14) 100% energy utilization, when the outlet is closed, the pump automatically stops, no equipment movement, wear, overload, heat.
(15) No dynamic seal, easy maintenance to avoid leakage, no dead point when working.
