摘要
介绍了磁性流体密封原理。通过数值计算对磁性流体密封的结构参数进行了设计,给出了磁钢材料及尺寸的设计原则,研究了单级密封压差与磁极斜角、极尖宽度和密封间隙的关系,分析了多级密封的级数对磁性流体多级密封的影响,给出了最优取值范围,对设计和应用磁性流体密封装置具有指导意义。
The principle of magnetic fluid sealing is introduced in this paper. We design main parameters for it through a numerical computer. So the magnetic material and the design principle of its dimension are got. Also in the paper, the relationship between the single sealing pressure and angle, teeth width, sealing clearance of pole pieces are researched. Through analyzing the effect of step number on multilevel magnetic pole sealing, the optimum value range is obtained, this is beneficial to the design and the application of the magnetic fluid sealing.
