Magnetic pump sliding bearing
Thread Content
Solution: The sliding bearings of magnetic pump are generally lubricated by the medium. Is there any specification regarding the temperature of this medium? I hope an expert can answer. . . {:2_42:}
There are no requirements regarding the temperature of the medium, but there are requirements for the maximum temperature of the bearings.
Graphite sliding bearings should have good heat resistance (the exact value is something that experts can determine); the purpose of preventing high temperatures is mainly to avoid demagnetization of the permanent magnets.
What is the required bearing temperature? Is 110℃ sufficient?
It depends on the specific material used; it must not react with sliding bearings. Currently, crystal silicon carbide (SSIC) is primarily used internationally, as it offers much better strength, toughness, and heat resistance compared to traditional graphite.
