CQB    Magnetic drive centrifugal pump

CQB magnetic drive centrifugal pump (referred to as magnetic pump), usually by the motor, magnetic coupling and corrosion resistant centrifugal pump. Its main feature is the use of magnetic coupling transmission power, no leakage, when the magnet rotates the motor drive magnetic coupling, magnetic flux through the gap and isolation units, acting on the magnet, the pump rotor and the motor synchronous rotation, no mechanical contact to transfer torque. In the power input shaft of the pump, the liquid is enclosed in a static isolation sleeve, so that there is no dynamic seal and no leakage.
CQB series magnetic pump is a new type of completely non leakage corrosion resistant pump developed by the national joint design group of magnetic pump. Its technical and economic indexes are similar to those of other similar products in the late 80s.
CQB series magnetic pump type and basic parameters in line with JB / T 7742 – 1995《small magnetic drive centrifugal pump type and basic parameters》 standard and 《small magnetic drive centrifugal pump of the supplementary provisions of the three standards》.

CQB    Magnetic drive centrifugal pump

CQB series magnetic pump is suitable for the industries of petroleum, chemical, pharmaceutical, metallurgy, electroplating, environmental protection, food, water treatment, film and printing photos, national defense, transportation is inflammable and explosive, volatile, toxic, rare and precious liquid and all kinds of corrosive liquid ideal equipment. Suitable for conveying the suction pressure is less than 0.2MPa, the maximum working pressure of 2.5MPa, temperature are less than 100, the density of less than 1600kg/m3, the viscosity is not greater than 30 x 10-6 m2/s not containing hard particles and fiber liquid.

CQB  Magnetic drive centrifugal pump product advantages

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%.

3.Stainless steel magnetic drive pump isolation sleeve is generally made of three parts: flange, thin wall tube and bottom plate through laser welding, each of the isolation sleeve must undergo pressure test, pressure test value is 2.5Mpa.

> Corrosion resistance from strong to weak order

High strength non-metallic materials

Hastelloy C alloy
