1.1, pump

magneticpump is generally used in corrosion-resistant, high strength engineering plastics, alumina ceramic, stainless steel for the production of materials with good corrosion resistance, and the media can be transported from pollution. Such as CQB Series magnetic drive pumps contact with the liquid part of the transport of chemicals by the anti-fluorine plastic alloy. Thermoplastic fluorine plastic alloy can be processed by the high molecular weight poly FEP and other plastic blends composed of more than one can be added to fill. Such as the high molecular weight polyethylene and Teflon FEP plastic alloy composition, the former accounted for 0.1%, a weight ratio of 99.9%, which accounted for 99.9%, a weight ratio of 0.1%, the use of dry powder were wet mill or dry powder method of grinding the blend method of manufacture. Sintering with hot or cold processed into various products such as methods to overcome the shortcomings of PTFE cold deformation and easy to extend service life.

magnetic bearing pump is immersed in transport medium, and medium conveyor lubrication and cooling. The more commonly used in the domestic bearing mostly graphite and reinforced plastics. Impregnated graphite, especially graphite has good self-lubricating, corrosion resistant, low friction coefficient, a wide range of applications, but more brittle graphite, lower strength, the bending of the shaft and partial overload is very sensitive, should pay particular attention. The steel matrix, porous bronze middle layer, the surface layer of the three plastic composite bearing high compressive strength, low coefficient of friction, dimensionally stable, noise damping, has been applied in recent years.

1.2, magnetic coupling

magnetic coupling is non-contact torque transmission so as to achieve no leakage of the key components. Generally disc-shaped and cylindrical forms. As the disc-shaped coupling ring magnet consists of two face to face in the sleeve and the composition of two axial force between the ring magnets, especially in power is large, a large axial force, it is very difficult to overcome, generally less used. Cylindrical external magnetic coupling including the rotor, the magnetic rotor and separated (from) cover three parts, outer magnetic rotor associated with the motor, and in the atmosphere, the magnetic rotor and shaft into one, the rotor is inclusion in the pump casing and immersed in every kit and transport medium, the sleeve is in between the rotor and fixed to the inside and outside the pump housing, so that the pump casing and the formation of isolated sets of internal connectivity, fully sealed chamber. Magnets, including magnetic rotor cylinder and the outer cylindrical magnetic rotor surface of the inner cylinder closely arranged along the circumferential direction to form a
