| Abstract: | Magnetic fluid seal is a new type of seal with the advantages of no leakage, long life and high reliability. The traditional magnetic fluid seal has been widely used in vacuum field. In order to make the magnetic fluid seal meet the working condition of high line speed and high sealing capability as the development of aviation, aerospace, military, petrochemical, etc., this paper introduced the composi- tion of magnetic fluid and the principle and the advantages of magnetic fluid seal. The development history and present situation of magnetic fluid seal was summarized. This paper also presented some new types of magnetic fluid seal such as the combination seal of magnetic fluid seal, magnetic fluid seal for sealing liquid, magnetic fluid seal for high speed sealing and the split magnetic fluid seal. |
