摘要
本文从液体与固体界面之间的关系 ,以及它们之间存在的表面张力入手 ,从另一个角度探讨了磁流体密封的机理。通过分析和试验 ,得出了磁流体密封能力与表面张力间的定性关系。在把磁性力作为附加的范德瓦引力的新思路基础上 ,提出了磁表面张力新概念 ,为研究磁流体密封能力作了一些基础性的工作。
This paper studies the principle of magnetic fluid seals in another way, which starts with the sruface tension acting between liquid and solid The qualitative relationship between the sealing property of magnetic fluid seals and surface tension is obtained through the theoretic analysis and practical test In this new assumption to consider the force of magnetic field as that of Van der Wals additional, a new conception of the magnetic surface tension is proposed This is the basic work for studying the sealing property of magnetic fluid seals [WT8.75HZ]
