摘要

The authors have studied the motion mechanism of the magnetic fluid in a reciprocating seal gap, on the basis of which the authors obtain an anti-pressure formula of the reciprocating shaft magnetic fluid seal from general Neavier-Stokes equation. In order to verify the correctness of the anti- pressure formula, the authors have calculated the magnetic field distribution of seal structure and have gotten the maximum still anti-pressure. Finally, the authors have verified the influence of speed and stroke on the seal anti-pressure.
