How many degrees of heat can a plastic magnetic pump withstand?

　　Plastic magnetic pump is a kind of pump driven by magnetic force, mainly by the pump head, magnetic actuator, motor, base and other parts, plastic magnetic pump has a wide range of applications, can be used in computer water cooling systems, solar fountains, desktop fountains, drinking fountains, medical equipment, gasoline dispensers, automotive cooling circulatory system, mold temperature machine and so on, plastic magnetic pump has a temperature-resistant properties, so how many degrees of high temperature plastic magnetic pump can withstand?

　　Plastic magnetic pumps can withstand temperature how many degrees

　　Magnetic pump temperature resistance by the pump body material and magnetic material temperature co-determination.

　　1、Pump body material

　　PP, PVDF, fluorine plastic, stainless steel and other materials, magnetic pump use temperature is about 75 ° C -120 ° C, PP material magnetic pump higher temperature 75 °, PVDF material magnetic pump higher temperature 100 ° C, stainless steel magnetic pump can withstand high temperatures of 120 ° C or less.

　　PP said polypropylene, temperature 90 ° C or less, corrosion resistance is not as strong as PVDF, can be resistant to strong acids and alkalis, cheaper than the PVDF material, in terms of weight, PP material to be lighter. FRPP said glass fiber reinforced polypropylene, can withstand high temperatures of 75 degrees.

　　PVDF called polyvinylidene fluoride, translucent or white, is a corrosion-resistant substances, long-term use of -40 ~ 150 ℃, the common temperature of 90 ℃, the working temperature up to 110 degrees Celsius, with good chemical resistance, high temperature resistance, oxidation resistance, resistance to radiation performance.

　　2、Magnetic materials

　　A, for temperatures lower than or equal to 80 ℃ working conditions, choose room temperature NdFeB material, its theoretical demagnetization temperature of 150 ℃, the magnetic energy product of this magnetic material up to 45 megagose OST.

　　B, higher than 80 ℃ working conditions are selected samarium cobalt 2:17, its magnetic energy product of 28 trillion gauss austen, can withstand the temperature limit is 350 ℃, in the conventional cooling conditions, limited to its * high use temperature of 280 ℃.

　　Domestic permanent magnets is the existence of demagnetization problems, imported permanent magnets generally do not demagnetize; normal magnetic magnet use temperature is 150 ℃ or less, imported individual 220 ℃ or less.

　　3、Temperature effect on NdFeB magnetic material:

　　A, when the temperature exceeds 100 ° C, the magnetic material will be deformed or cracked due to the large coefficient of thermal expansion;.

　　B, if long time in 100 ~ 110 degrees Celsius environment will make the magnetic material annealing and thus reduce its service life or even scrapped.
