Magnetic transmission centrifugal pump (referred to as magnetic pump) is the principle of modern magnetism, that is, when the motor drives the external rotor (ie, the external magnetic steel), the magnetic field is through the quarantine wire through the isolation cover to drive the inner rotor (ie inner magnetic steel) (ie inner magnetic steel) The assembly and the impeller rotate synchronously. Because the medium is closed in a static isolation set, the purpose of leak -free leakage pumping medium has completely solved the axis leakage of the mechanical transmission pump, and the design of the design of the full seal, non -leakage, non -pollution -free industrial industry Use pump. In addition, the magnetic pump is also the phenomenon of preventing running, rosing, dripping, and leakage in the chemical process, eliminating environmental pollution, creating a "leak -free workshop", "no leakage factories", and the ideal pump for safe and civilized production.

Magnetic pumps are widely used in the production process of petroleum, chemical, pharmaceutical, printing and dyeing, electroplating, food, and environmental protection. Delocular delivery.

In the field of petrochemical industry, more and more manufacturers require the process environment that has not been leaked in the media that they transport. In the process, the ideal leak -free pump is more urgent. Magnetic transmission high -temperature multi -stage pump and the magnetic pump product series with suspension separats solve the technical difficulties of conveying high temperature (350 ° C) and granular medium that conventional magnetic pumps have not been solved. Chemical pump. After a long -term productive continuous test test, users can be convinced that they choose the safest and most reliable pumps.

1. Principles of transmission

The magnetic pump is a new pump type that uses the working principle of a magnetic coupling to pass torque without contact. When the motor drives the external magnetic rotor rotation, the internal magnetic rotor and the impeller are synchronized to rotate through the action of the magnetic field, so as to achieve the pumping liquid The purpose is that because the liquid is closed in a static isolation case, it is a pump type with a full seal and leakage.

2. Features of magnetic pumps

The mechanical seal of the pump was canceled, and the disadvantages of the mechanical sealed centrifugal pump, drip, and leakage were completely eliminated. It is the best choice for leakage factories. Because the overcurrent parts of the pump are made of stainless steel and engineering plastics to achieve corrosion resistance. The magnetic coupling of the pump is combined with the combination of the pump body, so the structure is compact, convenient for maintenance, and safe and energy -saving. The inevitable running and fake shafts of the pump can play a role in overload protection on the transmission motor.

3. Magnetic pump use

The magnetic pump is widely used in oil, chemical, pharmaceutical, electroplating, environmental protection, water treatment, film and television washing, national defense and other departments for pumping flammable, explosive, toxic and valuable liquids. It is the ideal pump that creates non -leakage, pollution -free civilized workshops, and civilized factories.

Fourth, magnetic pump working conditions

The density of the magnetic pump conveying medium is not greater than 1300kg/m3, and the viscosity is not more than 30 × 10-6m3/s. The rated temperature of the conventional magnetic pump is made of a metal material or a F46 lining. The maximum working temperature is 80 ° C and the rated pressure is 1.6MPa; More than 60 ° C, the rated pressure is 0.6MPa.
