Basic knowledge of magnetic pump

Magnetic drive centrifugal pump (referred to as magnetic pump for short) is the application of modern magnetic mechanics principles, that is, when the motor drives the outer rotor (ie, outer magnetic steel) assembly to rotate, the magnetic force lines pass through the isolation sleeve to drive the inner rotor (ie, inner magnetic steel) through the action of the magnetic field The assembly and the impeller rotate synchronously, because the medium is enclosed in a static isolation sleeve, so as to achieve the purpose of leak-free pumping of the medium, completely solve the shaft seal leakage of the mechanical transmission pump, and the design is completely sealed, no leakage, no pollution. Industrial pumps. In addition, the magnetic pump is also an ideal pump to eliminate running, running, dripping, and leakage in the chemical process, eliminate environmental pollution, and create "leak-free workshops" and "leak-free factories" to achieve safe and civilized production. Magnetic pumps are widely used in the production processes of petroleum, chemical, pharmaceutical, printing and dyeing, electroplating, food, environmental protection and other companies to transport corrosive liquids that do not contain iron dust impurities, especially suitable for flammable, explosive, volatile, toxic and precious Liquid delivery.
      In the field of petrochemical industry, more and more manufacturers require a leak-free process environment for the media they transport. In some special occasions, such as transporting hot oil or granular media (such as sewage treatment), and chemical production In the process, it is more urgent to choose the ideal leak-free pump type. MT-MSP series magnetic transmission high-temperature multi-stage pump and magnetic pump product series with suspension separator solve the technical problems of high temperature (350 ℃) and granular media that conventional magnetic pumps have not solved, and can directly replace machinery Transmission type IH chemical pump. The MT series magnetic pumps have passed the long-term production continuous operation test, and users can be confident that they have selected superior, safe, superior and reliable pump types.
      1. Transmission principle
     Magnetic pump is a new type of pump that uses the working principle of magnetic coupling to transmit torque without contact. When the motor drives the external magnetic rotor to rotate, the internal magnetic rotor and the impeller are rotated synchronously by the action of the magnetic field, thereby achieving the pumping of liquid Purpose, because the liquid is enclosed in a static isolation sleeve, it is a completely sealed, leak-free pump type.
      2. Features of Magnetic Pump
      The mechanical seal of the pump is canceled, and the unavoidable disadvantages of running, running, dripping, and leakage of the mechanical seal centrifugal pump are completely eliminated, and it is an excellent and good choice for leak-free factories. Because the pump's over-flow parts are made of stainless steel and engineering plastics, the purpose of corrosion resistance is achieved. The magnetic coupling of the pump and the pump body are integrated into one body, so the structure is compact, the maintenance is convenient, and it is safe and energy-saving. The magnetic coupling of the pump can protect the transmission motor from overload.
       3. Magnetic pump use Magnetic pump is widely used in petroleum, chemical, pharmaceutical, electroplating, environmental protection, water treatment, film and television printing, national defense and other departments for pumping flammable and explosive due to its fully sealed, leak-free and corrosion-resistant characteristics. , Poisonous and precious liquids, is the ideal pump for creating civilized workshops and civilized factories without leakage and pollution.
      4. Working conditions of magnetic pump
      The density of the medium transported by the magnetic pump is not more than 1300kg / m3, and the viscosity is not more than 30 × 10-6m3 / S. The liquid does not contain ferromagnetic and fiber. The rated temperature of the conventional magnetic pump is superior to the metal body or F46 lining for the pump body. The high operating temperature is 80 ℃ and the rated pressure is 1.6MPa; the operating temperature of the high-temperature magnetic pump is ≤350 ℃; for the pump body is non-metallic material, superior high The temperature does not exceed 60 ° C and the rated pressure is 0.6 MPa.
      For the liquid with a density of more than 1600kg / m3, the magnetic coupling needs to be designed separately.
      The bearing of the magnetic pump is lubricated and cooled by the conveyed medium. The drum magnetic pump is strictly forbidden to run without load.
