Abstract: Magnetic
fluids, its sealing mechanism, and its sealing characters are brief
summarized. The types and components of sealing element, and
classification and steps of sealing element designing are introduced.
The effect of sealing element parameters on sealing performance, the
selection principle of sealing element parameters are studied. In
accordance with a concrete situation, a sealing element of one magnetic
source and two magnetic poles is selected and researched. A 30 stages of
sealing element is designed practically. The issues warranted careful
consideration in the process of manufacture and installation of sealing
element are discussed.
Key words: Magnetic
