The characteristics of magnetic pump use and working conditions and principles

Overview Magnetic drive centrifugal pump (hereinafter referred to as magnetic pump) is the application of modern magnetism principle, the use of permanent magnet magnetic torque transmission to achieve a new type of non-contact transmission, that is, motor driven outer rotor (ie outer magnet) assembly rotation , Through the action of the magnetic field, the magnetic force line drives the inner rotor (ie the inner magnet steel) assembly and the impeller to rotate synchronously through the isolation sleeve, and the medium is sealed in the stationary isolation sleeve so as to achieve the purpose of no leakage pumping medium and completely solve the problem that the mechanical Transmission pump shaft seal leakage, and design of the whole seal, no leakage, pollution-free new industrial pumps.

Magnetic pump is a chemical process to eliminate running, running, dripping, leakage phenomenon, eliminate environmental pollution, and create a "leak-proof workshop", "leak-free factory" to achieve safe and civilized production of the ideal pump. Widely used in petroleum, chemical, pharmaceutical, printing and dyeing, electroplating, food, environmental protection and other enterprises in the delivery of non-ferrous scrap corrosive liquids, especially for flammable, explosive, volatile, toxic and valuable liquid delivery.

In the field of petrochemicals, more and more manufacturers require a leak-free process environment for their media. In some special cases, such as transporting hot oil or granular media (such as sewage treatment), and chemical production The process, the more urgent need to choose the ideal leak-free pump. On the basis of producing CQ type magnetic pump, our company introduced domestic and foreign new technologies, developed MT-HTP series magnetic transmission high temperature chemical process pump, MT-MSP series magnetic drive high temperature multistage pump and suspension separator Magnetic pump products to solve the conventional magnetic pump has been unable to solve the delivery of high temperature (350 ℃) and with granular media technical problems, can directly replace the mechanical transmission of the IH chemical pump. MT series of magnetic pumps after long-term productive continuous operation test, the user can be sure that they are using the most safest and most reliable pump.

Transmission principle

Magnetic pump is the use of magnetic coupling principle of non-contact torque transmission torque of a new pump, when the motor drives the outer rotor rotates, the role of the magnetic field driven by the magnetic rotor and the impeller rotation in synchronism, so as to achieve the pumping of liquid For the purpose, it is a hermetically sealed, leak-free pump since the liquid is enclosed in a stationary isolation sleeve.

Pump features

Removed the mechanical seal pump, mechanical seal completely eliminate the pump inevitable run, run, drip, leakage of the shortcomings of the plant is the best choice for leaks.

As the pump flow components selected stainless steel, engineering plastics to manufacture, so as to achieve the purpose of corrosion resistance.

Pump magnetic coupling and pump body as a whole, so compact, easy maintenance, safety and energy saving.

Pump magnetic coupling can drive motor overload protection.

The purpose of the pump

Magnetic pump with its full seal, no leakage, corrosion-resistant features, widely used in petroleum, chemical, pharmaceutical, electroplating, environmental protection, water treatment, film and television printing, defense and other departments for pumping flammable, explosive, toxic and valuable liquid , Is to create a leak-free, non-polluting civilized workshops, civilized factories ideal pump.

Working conditions

Magnetic fluid pump medium density of not more than 1300kg / m3, the viscosity of not more than 30 × 10-6m3 / S of non-ferromagnetic and fiber-containing liquid. Conventional magnetic pump rated temperature for the pump body made of metal or F46 lining, the maximum operating temperature of 80 ℃, rated pressure of 1.6MPa; high temperature magnetic pump temperature ≤ 350 ℃; for the pump body is non-metallic, the maximum temperature is not Over 60 ℃, rated pressure of 0.6MPa.

For the transmission medium density greater than 1600kg / m3 of liquid, magnetic couplings need to be designed.

Magnetic pump bearings are transported by the lubrication medium cooling, drum magnetic pump is strictly prohibited no-load operation.
