Description
Technical field
The utility model relates to a kind of two diaphragm pump, specially refers to a kind of controllable pneumatic double diaphragm pump.
Background technique
Membrane pump with pneumatic drive is a kind of Novel conveyer tool, is a kind of pump class of present latest domestic grain husk.Employing pressurized air is power source, and for various corrosive liquids, with the liquid of particle, high viscosity, volatile, inflammable, hypertoxic liquid all can be taken out light and exhaust.It has four kinds of materials membrane pump with pneumatic drive: engineering plastics, aluminum alloy, cast iron, stainless steel.Membrane pump with pneumatic drive adopts respectively nitrile butadiene rubber, neoprene, fluorine rubber, teflon, poly-four or six ethene according to liquid mediums.To satisfy the needs of different user.Be placed in various special occasions, be used for pumping the medium that kind of conventional pumps can not be aspirated, all obtained satisfied effect.Owing to being used as power with atmosphere, so flow is initiatively reconciled with the variation of back pressure (resistance to flow output), be suitable for the fluid of medium-high viscosity.And the operation point of centrifugal pump thereby water to be benchmark set, if be used for the slightly high fluid of viscosity, then necessary supporting speed reducer or variable-frequency governor, cost is just progressive greatly, for gear pump also be difference so.Reliable and cost is low with pneumatic pump in inflammable and explosive environment, such as the conveying of fuel, gunpowder, explosive, because: the first, not all rightly after the ground connection can produce spark; The second, empty calory produces in the work, and machine can be not overheated; Three, fluid can be not overheated because the stirring of membrane pump with pneumatic drive convection cell is minimum.The abominable central authorities in the building site, as build the discharge of wastewater of building site, industrial and mineral, because the impurity in the sewage is many and composition is huge, and pipeline is easy to infraction, like this electric pump is just formed the too high environment of load, the motor feels hot rapid wear.Membrane pump with pneumatic drive can be adjustable by particle and flow, initiatively prevents to sluggishness during the pipeline infraction.Little being easy to of other pneumatic diaphragm pump volume moved, unnecessary ground, and occupation of land face is minimum, settles easy economy.Can be used as and move the formula material-handling pump.In the material that harmfulness, corruption property are arranged is processed, diaphragm pump can with material and the external world fully from every.Or assure and do not have the contaminating impurity raw material in some experiments.Can be used for carrying the more unsteady fluid of chemical temper, as: sensitive material, flocculation liquid etc.This is because the shearing force of diaphragm pump is low, and is little to the physical influence of material, because membrane pump with pneumatic drive has above characteristics, so membrane pump with pneumatic drive has just progressively been invaded the market of other pumps since being born, and occupies a part wherein in the world.As: spray paint, membrane pump with pneumatic drive has occupied absolute leading position in the ceramics, and in other some industries, as the market share that is enlarging it in environmental protection, waste water treatment, building, blowdown, the fine chemistry industry, and have the irreplaceable status of other pumps.
But the guide rod control problem inaccuracy of existing diaphragm pump, and design is complicated, the parts loss is high, the problem that anti-revisionist rate is high.
The model utility content
The utility model is for solving the deficiency of conventional art, a kind of controllable pneumatic double diaphragm pump is provided, mainly be to solve the in the past guide rod control inaccuracy of two diaphragm pump, and design is complicated, the parts loss is high, the problem that anti-revisionist rate is high, this patent have thoroughly been broken away from the principle that promotes barrier film in the conventional art with the combination of guide rod and air pressure, only utilize the ventilation of air pressure just can finish the function of whole product.
