The pneumatic diaphragm pump is a volumetric pump powered by compressed air and caused by the reciprocating deformation of the diaphragm. The working principle is similar to that of the plunger pump. Due to the working principle of the pneumatic diaphragm pump, the pneumatic diaphragm pump has the following characteristics:
(1) The pump will not overheat: the compressed air is used as the power. When the exhaust is exhausted, it is a process of expansion and heat absorption. When the pneumatic pump works, the temperature is reduced, and no harmful gas is discharged.
(2) No spark is generated: the pneumatic diaphragm pump does not use electric power for power, and prevents static sparks after grounding.
(3) It can pass through the liquid containing particles: because it is volumetric and the inlet is a ball valve, it is not easy to be blocked.
(4) The shearing force on the material is extremely low: how to suck in when working, so the agitation of the material is the smallest, which is suitable for the transportation of unstable substances.
(5) The flow rate can be adjusted, and a throttle valve can be added at the material outlet to adjust the flow rate.
(6) It has the function of self-priming.
(7) It can be run empty without danger.
(8) Can driving work.
(9) The fluids that can be transported are extremely wide, ranging from low viscosity to high viscosity, from corrosive to viscous.
(10) There is no complicated control system, no cables, fuses, etc.
(11) Small size, light weight and easy to move.
(12) It is easy to maintain without lubrication, and it will not pollute the working environment due to dripping.
(13) The pump is always efficient and will not be degraded by wear.
(14) 100% energy utilization, when the outlet is closed, the pump automatically stops, there is no equipment movement, wear, overload, heat.
(15) There is no dynamic seal, the maintenance is simple and avoids leakage, and there is no dead point during work.
