Magnetic fluid:Magnetic fluid is a new-functional material which possesses magnetic feature. Magnetic fluid is a colloidal fluid that is mixture of Nami grains with diameter of 10nami, and fluid in which the grains are evenly dispersed. It posses both fluidity and gradient.
Sealing principle:Magnetic Fluid Sealing technology is realized by the characteristics of Magnetic Fluid in respond to the magnetic field. When Magnetic Fluid is poured into high performance permanent-magnets, in the clearance formed by the pole shoe and the polar axis that is a good flux guide, the magnetic fluid creates several fluid “o” rings activated by the magnetic field. And that is the principle of sealing of magnetic fluid.
Characteristics of Magnetic Fluid:
1. Long life: Since magnetic fluid makes use of fluid “o” rings to seal,and there is no damage of contacting with solid. The life of sealing apparatus relied on the life of bearings. So this apparatus has been in operation for over ten years with no maintenance.
2.The best mode of transmission: Magnetic Fluid sealing is a kind of “fluid-solid” sealing. There is no seal wear that consists in traditional sealing because of the “solid-solid” mode. There is no loss, so the whole power goes into transmission mode.
3. Non-leakage: This apparatus is almost leakage-proof, even it is tested by the helium mass spectrograph.
4.High vacuum Degree: Magnetic Fluid maintains seal integrity even in hard vacuum to better than 1×10-6Pa.
5. Fit for different revolving speed: The magnetic fluid keeps steady at high revolving speed.
6. Good capability of pressure resistance: the margin of pressure resistance between every lever is about 0.025MPa. The capability of pressure resistance increases with increasing lever. It’s widely accepted that magnetic fluid is one kind of non-leakage advanced technology.
