| 摘 要： | 研究了往复轴磁性液体密封间隙内磁性液体的运动机理，在此基础上从纳韦-斯托克斯方程出发得出了往复轴磁性液体密封的耐压公式。为了验证该公式的正确性，对密封结构的磁场分布进行了有限元计算，得出了密封结构的最大静止耐压能力，并且在实验台上验证了速度和行程夺密封耐压能力的影响。

| Abstract: | 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 Navier 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. \{ |
