I. Magnetic transmission centrifugal pump (abbreviated as magnetic pump) is a new type of pump that applies the principles of modern magnetic mechanics and uses the magnetic transmission of permanent magnets to achieve non-contact transmission of torque, that is, the motor drives the outer rotor (that is, the outer magnetic steel) assembly During rotation, the magnetic field lines pass through the isolating sleeve to drive the inner rotor (ie inner magnetic steel) assembly and the impeller to rotate synchronously through the action of the magnetic field. Since the medium is enclosed in the stationary isolating sleeve, the purpose of pumping the medium without leakage is completely solved. The shaft seal of the mechanical transmission pump leaks, and the new industrial pump is designed to be fully sealed, leak-free and pollution-free.
2. The magnetic pump is an ideal pump for eliminating running, dripping, dripping and leaking in the chemical process, eliminating environmental pollution, creating "no-leak workshops" and "no-leak factories" and realizing safe and civilized production. Widely used in petroleum, chemical, pharmaceutical, printing and dyeing, electroplating, food, environmental protection and other enterprises to transport corrosive liquids without iron filings, especially for flammable, explosive, volatile, toxic and precious liquids. delivery.
3. In the petrochemical industry, more and more manufacturers require a leak-free process environment for the medium they transport. In some special occasions, such as the transport of hot oil or particulate media (such as sewage treatment), and In the chemical production process, it is more urgent to choose the ideal non-leakage pump type. based on the production of CQ type magnetic pumps, our company has introduced domestic and foreign new technologies and successfully developed MT-HTP series magnetic transmission high temperature chemical process pumps, MT-MSP series magnetic transmission high temperature multi-stage pumps and The magnetic pump product series solves the technical problems of high temperature (350 ° C) and particulate media that conventional magnetic pumps have not been able to solve. It can directly replace the mechanical transmission IH chemical pump. MT series magnetic pumps have been tested for long-term productive continuous operation. Users can be sure that they choose the safest and most reliable pump type.
4. The magnetic pump is composed of a pump, a magnetic actuator, and a motor. The key components of the magnetic actuator are composed of an outer magnetic rotor, an inner magnetic rotor and a non-magnetically permeable isolation sleeve. When the electric motor drives the outer magnetic rotor to rotate, the magnetic field can penetrate the air gap and non-magnetic substances, and the inner magnetic rotor connected to the impeller is rotated synchronously to achieve non-contact transmission of power and convert the dynamic seal into a static seal. Because the pump shaft and the inner magnetic rotor are completely closed by the pump body and the isolating sleeve, the problem of "run, run, drip, leak" is completely solved, and the flammable, explosive, toxic and harmful media in the refining and chemical industry are leaked through the pump seal. The potential safety hazards have effectively guaranteed the physical and mental health and safety of employees.
V. Working principle of the magnetic pump The n pairs of magnets (n is an even number) are assembled on the inner and outer magnetic rotors of the magnetic actuator according to a regular arrangement, so that the magnetic parts form a complete coupled magnetic system. When the inner and outer magnetic poles are opposite to each other, that is, the displacement angle Φ = 0 between the two magnetic poles, the magnetic energy of the magnetic system is the lowest at this time; when the magnetic poles are rotated to the same polarity, the displacement angle between the two magnetic poles Φ = 2π / n, the magnetic energy of the magnetic system is the largest at this time. After the external force is removed, the magnetic force will restore the magnet to the lowest magnetic energy state because the magnetic poles of the magnetic system repel each other. The magnet then moves, which drives the magnetic rotor to rotate.
