Are magnetic pumps resistant to high temperatures?

　　Magnetic pumps have a certain degree of high temperature resistance, but its specific degree of high temperature resistance depends on the material of the pump body and magnetic material. The following is a detailed analysis of the high temperature resistance of magnetic pumps:

　　First, the magnetic pump high temperature resistance ability overview

　　Magnetic pump is a new type of pump that applies the principle of modern magnetism and utilizes the magnetic drive of permanent magnets to realize the contactless transmission of torque. As the medium is enclosed in the static isolation sleeve, the magnetic pump is able to realize leakage-free pumping medium, which is one of its significant features. At the same time, in order to cope with high temperature environment, magnetic pump in the design of a variety of measures to improve its high temperature resistance.

　　Second, the key factors of high temperature resistance of magnetic pumps

　　Pump body material: magnetic pumps are mainly made of PP, PVDF, fluorine plastic, stainless steel and other materials. The pump body of different materials has different high temperature resistance. For example, PP material magnetic pump higher temperature up to 75 ° C, PVDF material magnetic pump higher temperature up to 100 ° C, while the stainless steel magnetic pump can withstand high temperature up to 120 ° C or less.

　　Magnetic material: the magnetic material of the magnetic pump also has an important impact on its ability to withstand high temperatures. Room temperature NdFeB material is suitable for working condition with temperature not higher than 80°C, while Samarium Cobalt 2:17 (coded as S26H) is suitable for working condition higher than 80°C. The limit of its tolerable temperature is 350°C, and the limited use temperature is 280°C under the condition of conventional cooling.

　　Third, the special design of high-temperature magnetic pumps

　　In order to further improve the high temperature resistance of the magnetic pump, some high-temperature magnetic pumps also uses a double insulation (cooling) device, you can use steam (nitrogen, water) on the pump body medium insulation (or cooling), thus extending the life of the pump, and to ensure that the medium will not be condensed, crystallized, vaporized in the transmission process. In addition, high temperature magnetic pump overflow parts can also be used as needed 304, 304L, 316, 316L and other corrosion-resistant materials to enhance its high temperature and corrosion resistance.

　　Fourth, the application of high temperature magnetic pumps

　　High temperature magnetic pump is widely used in petroleum, chemical, pharmaceutical, smelting, electroplating, environmental protection, food and other industries, used to transport high-temperature flammable, explosive, volatile, toxic, rare and precious liquids and various types of corrosive liquids. Its characteristics of no leakage, no pollution, high efficiency and energy saving make it have a wide range of application prospects in these fields.

　　V. Conclusion

　　In summary, the magnetic pump has a certain high temperature resistance, but the specific degree of high temperature resistance depends on the material of the pump body and magnetic material. When choosing a magnetic pump, it is necessary to choose the appropriate material and design according to the specific working environment and media characteristics. At the same time, in order to ensure the long-term stable operation of the magnetic pump in the high temperature environment, it is also necessary to carry out regular maintenance and repair.
