CQ type pump, magnetic pump for short, is a by magnetic actuators (magnetic coupling) to complete the no touch of torque transmission and static seal instead of dynamic seal, magnetic pump reach completely without leakage of the centrifugal pump.
Magnetic pump from the pump, magnetic coupling and drive motor three. Magnetic pump shaft is provided with a wheel, the right end is provided with an inner magnetic rotor, the pump shaft is supported by sliding bearings. The pump bracket is connected with the pump and motor to ensure the position accuracy of the magnetic rotor in the exterior and interior. When the motor is driven outside the magnetic rotor rotates, the magnetic field after air gap and septal (from) set, shares inner magnetic rotor synchronous rotation and femoral artery by the rotation of the impeller.
Fluorine magnetic pump usually choose corrosion resistant, high strength engineering plastics, corundum ceramic, stainless steel magnetic pumps as the production of materials with good corrosion resistance, and can make is transported from the contaminated medium. The touch of the CQB series magnetic pump is transported liquid some of which are made of fluorine plastics alloy produced by the chemicals. Fluorine plastic alloy by thermoplastic processing of ultra high molecular weight poly (fluorinated ethylene propylene) and more than one other plastics blend composition, adds the filler. Such as magnetic pump by ultra high molecular weight poly FEP and PTFE composed of plastic alloy, the former accounted for component than 0.1% to 99.9%, which accounted for component than 99.9% a 0.1%, the choice of dry grinding and dry wet grinding of blending methods are produced. With hot or cold press sintering processing methods into a variety of finished, overcome the Teflon cold flow and easy deformation defects, can prolong the service life.
Magnetic pump bearings are immersed in the transport medium, and smooth and cool delivery media. The more commonly used in the magnetic pump bearings are graphite and reinforced plastics. Special graphite is impregnated graphite is distinguished from smooth, corrosion resistance, friction coefficient is low, the use of the scale is very wide, but the graphite brittle strength is lower, on magnetic pump shaft bending and part of overload is very sensitive, should pay special attention to. To steel as matrix and porous bronze as the intermediate layer and the plastic as the surface layer of the three layer composite bearing high compressive strength, low friction coefficient, stable scale, noise and vibration damping, the obtained using.
