1.Casting
The pump impeller of the company by CZ standard chemical process pump castings (most market by IH magnetic pump pump impeller casting), the design pressure is 2.5Mpa, each of the pump body through the bearing test, even tiny leakage will be melted recast. Pump body after three passivation treatment, to ensure that the pump body color. Using the latest hydraulic design software to design hydraulic model, with excellent performance, which is to ensure long-term safe and reliable operation of the first major.
2.Magnetic pump magnetic circuit transmission principle
(a).The magnetic circuit of Halbach, which is developed by Shanghai Dian Ji University, which is dense, magnetic and push-pull, is magnetized in different directions according to certain law, and the maximum torque is transmitted by the magnetic force.
(b).Each pole magnet is composed of N (N is odd) rectangular magnetic stripe, its width is about fan (magnetic tile type) 1/5 or 1/3, the use of magnetic or magnetic field strength was increased by about 30%, the magnetic gap when the magnetic amount is reduced by about 30%, greatly reduce the eddy heat pump, improve the efficiency of 2~3%.
(c).Magnetic gap 7 ~ 9mm, cooling and lubricating the flow area is large, and can take away the vortex heat, reduce the temperature of the medium, to prevent the media cavitation.
NdFeB permanent magnet is used in the internal and external magnetic rotor of normal temperature stainless steel magnetic pump:
>Advantage
The maximum magnetic energy product (BHmax) value is 5~12 times of ferrite magnet
Can absorb up to 640 times its own weight
Good mechanical properties, easy cutting
Low price
>Shortcoming
High magnetic loss under high temperature
Easy corrosion
Efficiency improvement 2~3%.
