Abstract: | This paper discusses the effects of viscous pumping in a magnetic fluid seal under a rotating load. The Reynolds' equation is presented for the seal based on magnetic fluid mechanics. Expressions are given for obtaining pressures in the seal, and eccentricities of the rotating shaft because of viscous pumping and seal pressures. Numerical calculations are carried out for some sample problems and for the effect of the strength of the magnetic flux on the fluid pressure. Also, eccentricities of the shaft in the seal and the seal pressures are clarified. |
