Diaphragm pump are you know, here introduces the category and principle of the diaphragm pump

, diaphragm pump, also known as control by accepting unit outputs a control signal, modulation from engine operation to change fluid flow, often with the help of the dynamic air, electric device, liquid medium, etc. Although pneumatic double diaphragm is a new type of conveying machinery, the diaphragm pump is a traditional piston pump, centrifugal water pump, oil pump insulation type of ideal replacement. Diaphragm water pump type a, electric diaphragm pump, electric diaphragm pump on the motor through reducer drive around on both ends of the column on the surface of the battery diaphragm tandem reciprocating motion. In about two pump cavity, containing four one-way valves up and down the movement of the diaphragm, causing changes in the working chamber volume, forced four one-way valves open and close alternately, thereby the liquid suction and discharge. Two-cylinder double-acting diaphragm pump is key equipment of coal water slurry conveying coal chemical industry field, two-cylinder double-acting diaphragm pump power end is mainly composed of drive shaft and the pulley and other key components. Double-acting refers to both end face of the piston is working face, each crankshaft rotation for a week, each piston end complete a work process. But because of a piston has two face, the working process of the actual completed two ( While the exhaust, the other side of the suction) ; Triplex single acting refers to three cylinder piston only one face of each crankshaft rotates, each cylinder only complete a work process. Electric diaphragm pump features ( 1) Because the diaphragm is medium and transmission machinery parts separately, so the media would never leak outward. No shaft seal and pump itself, greatly extend the service life. Without irrigation water diversion, self-priming capacity of more than 7 meters. Small volume light weight: the adoption of planetary cycloid drive structure, so the pump type for small size like to compare with the same type pump, the volume weight are falling by half. ( 2) body medium flows through the part, according to user requirements, can be divided into cast iron, stainless steel, rubber lining, motor divided into common type, explosion-proof type, speed type. Through performance is good, under 10 mm in diameter of particle, mud, etc all can easily pass. 2, single pneumatic diaphragm pump, pneumatic diaphragm pump there are four kinds of its material: engineering plastics, aluminum alloy, cast iron, stainless steel. Pneumatic diaphragm pump according to different liquid medium with NBR, chloroprene rubber, fluorine rubber, ptfe, poly vinyl hexagon. Pneumatic diaphragm pump adopts compressed air as power source, is a kind of changes caused by deformation of diaphragm reciprocating displacement volume pump, its working principle is akin to plunger pump. Pneumatic single diaphragm pump features ( 1) does not overheat, without harmful gas discharge. Empty can run, but there is no danger. ( 2) Can conveying fluid is very broad, from low to high viscosity, viscosity sticky from corrosion. ( 3) It is not easy to be blocked. Does not produce sparks. Can diving, one hundred percent of the energy use, when close the export, automatic stop pump. ( 4) For material agitation is small, be applicable to the unstable material conveying. Small volume, light weight, easy to move. ( 5) Flow adjustable, can be in material with throttle valve to regulate traffic. ( 6) Has the function of self-priming. No dynamic seal, simple maintenance to avoid the leakage. Work without dead center. Three pneumatic double diaphragm pump, pneumatic double diaphragm pump as power using compressed air, nitrogen or natural gas. The main orientation ( Pneumatic) Distribution of compressed air control valve to the gas chamber, the uniform pressure on the inner surface of the diaphragm. Another suitability and exhaust gas from the pump through port discharge valve components guide. Pneumatic double diaphragm pump stroke mechanical drive within the mobile pneumatic double diaphragm pump suction diaphragm plate and the alignment of the drive plunger contact, mobile pilot valve core. Pilot valve activated, then the other end of the directional valve to the main signal pressure, pneumatic double diaphragm pump made of compressed air direction direction changing internal chamber and repeat on the other side of the continuous transmission of movement to complete medium. Pneumatic double diaphragm pump characteristic of pneumatic double diaphragm pump and the characteristics of single diaphragm pump, double diaphragm pump only refers to the double suction fluid cavity, single diaphragm pump is a liquid absorption chamber. Diaphragm pump pressure cannot raise, limited by air pressure. Diaphragm pump flow is usually not too big, most of the application in the system. With traditional use in large flow of centrifugal pump are used in different occasions.
