Why Do High-Temperature Magnetic Pumps Require an Internal Magnet Rotor Magnetizing Device?

The high-temperature magnetic pump utilizes modern magnetic principles to achieve non-contact indirect rotation through permanent magnets, serving as a chemical process pump for transporting various highly corrosive media. In simpler terms, the motor-generated magnetic field drives the impeller to rotate, thereby accomplishing the goal of conveying the medium. Moreover, these pumps feature a sealed structure that completely prevents leakage during transportation.

The high-temperature magnet pump's internal magnet rotor magnetization device is mainly composed of a magnetizing chuck, a magnetic iron yoke, a coil, and a coil frame. The magnetizing head is cylindrical, with its front end located within the ring magnetic iron yoke. The front end is axially mounted with a coil frame, around which the coil is wound. In use, connect the device's two terminals to the stator terminals of a permanent magnet motor, and then place the cylindrical workpiece between the four magnetization nozzles. Once the power is connected, the workpiece can be magnetized.

Why Do High-Temperature Magnetic Pumps Require an Internal Magnetic Rotor Magnetizing Device? Statistics show that the lifespan of magnetic pump rotors without this device is typically less than a year. In daily operation, issues such as slippage, seizing, demagnetization, and failure to pump media are common, causing significant disruptions to normal production. This is a major headache and a significant safety hazard. A slight mishap can lead to pump body damage and scrapping, and in severe cases, even cause safety accidents.

The magnetic drive pumps equipped with an internal magnetized rotor magnetization unit have seen a significant increase in service life. They can meet various design requirements for head and flow rates. Additionally, the energy performance of the magnetic drive pumps has been enhanced, boasting higher hydraulic efficiency and greater stability.
