The working principle of pneumatic pump diaphragm is a kind of compressed air as the power (make the mechanical work of various forces), by the diaphragm reciprocating deformation caused by the volume change of the positive displacement pump, its working principle is similar to the plunger pump. usually, pneumatic diaphragm pump has plastic, aluminum alloy, cast iron, stainless steel four materials, can transport a variety of corrosive liquid, liquid with particles, high viscosity, volatile, flammable, highly toxic liquid. It occupies a leading position in the painting and ceramics industry, and in some other industries, such as environmental protection, waste water treatment, construction, sewage, fine chemical industry is expanding its market share, and has the irreplaceable position of other pumps.
In general, 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, pneumatic pump working temperature is reduced (reduce), no harmful gas discharge.
(2) no electrical spark: pneumatic diaphragm pump does not use electricity for power, after grounding and prevent electrostatic (is a static state of charge) sparks
(3) No lubrication so easy maintenance, will not pollute the working environment due to drip.
(4) Energy utilization, when the outlet is closed, the pump will automatically stop, and the equipment will move, wear, overload and heat
(5) The fluid that can be transported is extensive, ranging from low viscosity to high viscosity, and viscous to viscous from corrosion.
(6) can dive work.
(7) No dynamic seal, easy maintenance to avoid leakage. There are no dead ends at work.
(8) There is no complex control system, no Cable, fuse, etc.
(9) volume small, light weight, easy to move.
(10) Can pass through liquid containing particles: because the volume type work and the inlet is ball valve, so it is not easy to be blocked.
(11) Pneumatic diaphragm pump can always be maintained, not because of wear (a basic type of parts failure) and reduce.
(12) the shear force of the material is very low: how to suck in how to spit out when working, so the agitation of the material, suitable for the transport of unstable material
(13) The flow (unit: cubic meters per second) can be adjusted, can be installed at the outlet of the material throttle valve to adjust the flow.
(14) Has the function of self-priming.
(15) can run empty, without danger.
