Period of use magnet

Magnet in contact with the process of the fluid, the interior of the magnetic energy will produce some irreversible loss, when the loss exceeds 30% of the original strength, or the surface of the bag off of the metal, stainless steel tube rupture when worn. When faced with these situations should be timely replacement bar magnet, the Magnetic Drawer must not allow the magnet has been leaked to continue working. Magnets are relatively brittle, oil coated on the surface, this will impact on the environment. In China, the production of magnets can work under heavy 1-2 years, if it is to work under light load 7-8 years.
