Pneumatic membrane pump is a kind of new-style conveyer fetterses, it is a kind of home's at present most original pump kind. Use compress air to be dynamical source, to all sorts of caustic liquids, take the liquid of grain, volatilize tall viscosity, easily, combustible, virulent liquid, all can give smoke light to be sucked. Its have pneumatic membrane pump 4 kinds of material are qualitative: Plastic, aluminium alloy, cast-iron, stainless steel. Membrane pump uses Ding Qing respectively according to different liquid medium balata of balata, chloroprene rubber, fluorine, get together 4 fluorine ethylene, get together 46 ethylene. In order to satisfy the need of different user. Find a place for in all sorts of special situations, use pump all sorts of groovy pump cannot the medium of pump, all obtained satisfactory result. One, because pneumatic membrane pump has above characteristic,comfortable use of pneumatic membrane pump closes, go up in the world so membrane pump since the market that other pump is invading stage by stage since be born, and by very dominant status, and in other a few industries, processing, building, blowdown, careful like environmental protection, liquid waste the market share that it is enlarging in changing, have the place that other pump cannot replace. The advantage of pneumatic membrane pump depends on: 1.

Because air makes motive force, so discharge follows back pressure (exit obstruction) change and self-correcting, suit to use the fluid of Yu Zhonggao viscosity. And the working characteristic of centrifugal pump is good for fiducial set with water, if be used at the fluid with tallish viscosity, need machine of decelerate of form a complete set or frequency control implement, cost rose with respect to big earth, to gear pump also be likewise such. 2.

Be in combustible the environment that explodes easily is useful pneumatic pump is reliable and cost is low, be like the transportation of fuel, gunpowder, dynamite, because: The first, scintilla cannot arise after ground connection; The 2nd, arise without quantity of heat in the job, machine won't overheat; The 3rd, fluid won't overheat because of body of membrane pump convection churn the smallest. 3.

Abominable place is made in labour, if the liquid waste of construction site, factory is discharged, because the impurity in sewage is much and part is complex, pipeline jams easily, form the circumstance with exorbitant bear to electric pump so, electric machinery is calorific sun damage. Pneumatic membrane pump can carry grain and discharge is adjustable, when conduit jams stop automatically to come expedite. 4.

Membrane pump volume is additionally minor move easily, do not need foundation, cover an area of an area small, bring handy economy. Can carry pump as movable type stock. 5.

In harm sex, caustic stock is handled, membrane pump can separate stock and outside completely. 6.

Or it is card of middleman and guarantor of a few experiments pollute raw material without foreign matter. 7.

Can use at carrying chemistry to compare not stable fluid, be like: Sensitive data, garrulous coagulates fluid. Because the shearing force of membrane pump is small,this is. 2, principle of job of pneumatic membrane pump 1.

Compress air to be motivation. 2.

It is one kind is out of shape by diaphragm move back and forth the cubage pump that causes cubage change, its job principle fills in at column approximately pump, as a result of the characteristic of principle of membrane pump job, because this membrane pump has the following characteristic: (1) pump won't overheat: Compress air to make motive force, be one expands when exhaust the process of absorption of heat, the temperature when pneumatic pump works is dropped, without harmful gas eduction. (2) won't produce electric spark: Pneumatic membrane pump need not motivation of electric master piece, ground connection hind prevented electrostatic scintilla again. (3) can pass contain grain liquid: Because cubage type works and the entrance is ball valve, not allow to be blocked up easily so. (4) polar to the shearing force of stock: It is how engulf is spat when the job, be opposite so of stock churn the smallest, apply to what do not stabilize material to carry. (5) discharge is adjustable, processing can be exported to add outfit throttle to move section discharge in stock. (6) have the function that sucks oneself. (7) OK and airborne sex, and won't have risk. (8) can dive the job. (9) the fluid that can carry is very extensive, from low viscosity to tall viscosity, from caustic get ropy. (10) without complex control system, wait without cable, fuse. (11) bulk small, weight is light, facilitating shift. (12) need not lubricate maintenance is so simple, won't pollute working environment as a result of drop leakage. (13) pump can keep efficient from beginning to end, won't because of wear away and reduce. (14) 100 percent energy is used, should shut export, pump stops automatically machine, setting shift, wear away, overload, calorific. (15) did not move sealed, maintenance is simple avoided to divulge. Dead center is not had when the job. CNC Milling
