Details QBY plastic pneumatic diaphragm pumps: plastic diaphragm, plastic diaphragm pumps, pneumatic diaphragm pumps a plastic, plastic pneumatic diaphragm pump Overview: QBY type plastic diaphragm pumping both liquid flow, and can convey some uneasy flow of medium, has a number of advantages transportation machinery pump, submersible pump, shield pump, mud pump and other impurities. 1, no irrigation water. Suction lift up to 5m. Head up to 50m. Outlet pressure ≥5bar. 2. Wide flow and good performance. It allows maximum particle diameter of 10mm. Pumping mud, and impurity of the pump wear little; 3, lift and flow can be achieved by the valve open stepless adjustment (pressure adjustment is between 1-7 bar): 4, the pump with no moving parts, no shaft seal, diaphragm pump pumping the media and pump running parts, working medium is completely separated from the transmission medium does not leak out. So pumping toxic and flammable or corrosive the medium, it will not cause environmental pollution and danger to personal safety; 5, do not have electricity. Flammable and explosive places safe and reliable; 6, can be immersed in media work; 7, easy to use, reliable, open stop simply open and close the gas valve. Even a long time because of accident or sudden stop no medium run pump will not be damaged. Once the overload, the pump will automatically stop the earth, self-protection function. When the load is normal, also can start automatically; 8, simple structure, less wearing parts, simple structure of the pump, installation and maintenance, pumping The media do not come into contact with the valve, linkage and other moving parts, unlike other types of pump performance due to wear leaving the rotor, pistons, gears, blades and other parts of the gradual decline: 9, can transmit the adhesive liquid (viscosity 10,000 cp); 10, this pump without oil lubrication, even if idle. Nor any effect on the pump, which is characteristic of this pump. Second, the plastic diaphragm pump Features: 1, since the air-powered, so flow with back pressure (outlet resistance) changes automatically adjusted suitable for high viscosity fluids. The centrifugal pump operating point is the water as a benchmark to set a good, if slightly higher viscosity of the fluid, you need to complete reducer or frequency converter, the cost will be greatly enhanced, for gear pump is the same. 2, explosive atmosphere using pneumatic pumps reliable and low cost, such as fuel delivery, because: first, grounded not produce sparks after; second, work no heat generation, the machine will not overheat; s Third, the fluid does not overheat because the diaphragm of the fluid stirring minimum. 3, at the site where the bad, such as waste water construction sites, mines, because the sewage impurities and complicated, easy to plug the pipeline, so that the load is too high the pump to be formed, the motor heat vulnerability. Pneumatic diaphragm pump through the particles and adjustable flow stops automatically when the pipes get clogged to smooth. 4, another diaphragm small easy to move, without foundation, of the ground is extremely small, easy to install and economical. It can be used as portable pumps. 5, hazardous, corrosive material handling, the diaphragm material can be completely separated from the outside world. 6, or the number of tests to ensure that no impurity contamination of raw materials. 7, can be used to transport relatively unstable chemical properties of a fluid, such as: photographic materials, flocculation liquid. This is because the diaphragm low shear, little physical effect on the material. Pneumatic diaphragm pump works: 1, powered by compressed air. 2 is a reciprocating diaphragm deformation caused by the volume change of the volume of the pump, it works similar piston pump, since the characteristics of diaphragm pump works, so diaphragm pumps have the following characteristics: (1) Pump will not overheat: compression air as the driving force in the expansion of the exhaust is an endothermic process, pneumatic pump when the operating temperature is lowered, no harmful gas emissions. (2) does not have a spark: pneumatic diaphragm pumps without electricity for power, ground and then prevent electrostatic spark (3) through a liquid containing particles: type of work and because of the volume of imports for the ball, it is not easily blocked. (4) low shear force on the material: how work is sucked into how spit, so the smallest stir of materials suitable for the delivery of unstable substances (5) flow can be adjusted, can be installed in the material at the outlet section valve to regulate the flow. (6) has a self-priming function. (7) can be dry run without danger. (8) Diving work. (9) The fluid can be delivered in a very wide range, from low viscosity to high viscosity, from the corrosive viscous. (10) No complex control system, no cable, fuses. (11) small size, light weight, easy to move. (12) without lubrication so maintenance is simple and will not pollute the environment due to the leakage. (13) pump is always able to maintain efficient, will reduce wear. (14) 100% of energy use, when to close the outlet, the pump automatically shut down, equipment movement, wear, overload, fever (15) no dynamic seal, easy maintenance to avoid leaks. Work no dead spots. Third, the plastic diaphragm Uses: 1, pumping peanut butter, pickles, mashed potatoes, small sausage, jam apple syrup, chocolate and so on. 2, pumping paints, gums, pigments. 3, adhesives and glue, all kinds of available pump draw. 4, all kinds of tile, porcelain, tiles and pottery glaze. 5, after the oil well drilled by pumping sediment and filling. 6, pumping various creams and fillers. 7, pumping all kinds of sewage. 8, with a pump for the tanker, barge warehouse clearance absorb water. 9, hops and yeast slurry, syrup, molasses. 10, the pump shaft, tunnel, tunnels, ore dressing, slag in the water. Pumping cement grout and mortar. 11, all kinds of latex. 12, all kinds of abrasive, corrosive, oil and mud, grease and general cleaning containers. 13, a variety of toxic, flammable, volatile liquid. 14, all kinds of acid, alkali, strong corrosive liquids. 15, a variety of high temperature liquid maximum resistance 150 ℃. 16, as a variety of solid-liquid separation equipment pre-delivery pressure device. Fourth, the plastic diaphragm pump Model significance: For example: QBY-40 QBY- pneumatic diaphragm 40- Importers diameter (mm)
