The working principle of the magnetic pump is: the n pairs of magnets (n is an even number) in accordance with the law arranged in the magnetic clutch inside and outside the rotor, so that the magnet part of each other to form a complete coupling of the magnetic system. Since the magnetic poles of the magnetic system are mutually exclusive, the magnetic force will restore the magnet to the state with the lowest magnetic energy. The magnet thus produces a movement which in turn causes the magnet rotor to rotate. The status quo of magnetic pump production and development of magnetic materials and sliding bearings, in order to ensure the quality of the project, we can refer to the following steps in the selection of magnetic pump: 1, For the pump whose power is less than 10KW, choose the magnetic pump to ensure the use effect. 2, when the pump shaft power is greater than 10KW or the medium temperature is higher than 100 ℃, the selection of domestic magnetic pump should be carefully handled, deal with the magnet material, bearing material structure to be limited, if necessary, should be used shielding pump. 3, the current domestic magnetic pump manufacturers are generally medium and small plants, development and research and development tools is weak. For the pump beyond the range of product parameters, it is generally not suitable for the manufacturer to develop or develop the pump to ensure the quality and progress of the project. Domestic main magnetic pump manufacturers and their products in Table 1-1. 4, Magnet material is related to the quality of the pump life, reliability and price, the order should be clear magnetic materials, suppliers and manufacturers of its performance indicators. Responding to the material and life of plain bearings should also be made clear. In this way, the selected magnetic pump is not only highly efficient, but also has its own unique properties: preventing particles from entering, preventing demagnetization, preventing dry friction and other properties, and achieving a multiplier effect for the project. 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, clean Wenming workshop, Wenming factory ideal pump.
