摘　　要：永磁传动基于永磁体间的磁力作用原理,实现原动机与工作机之间的非机械连接,可向一切密封空间传递回转运动或往复运动,变动密封为静密封,实现了零泄漏和绝对密封。从泄漏与污染、泄漏与密封的关系,提出了绝对密封技术。简要介绍了磁力传动与密封原理,综述了国内外磁力传动泵的发展与应用情况,介绍了作者在泵、阀、釜的应用研究成果。针对我国在该领域存在的技术关键,提出建设性意见与发展战略。The magnetic driving （MD）, based on magnetic force of magnets, transmits rotary or reciprocating movement to closed vessels and realizes non-mechanical connection of driving and driven machine, changing dynamic seal to static one, and achieving absolute seal. The paper is put toward absolute seal technique from the relationship of leak and pollution, leak and seal. The seal principle based on magnetic drive is briefly described. Application and development of magnetic pumps is summarized. Also the authors＇ achievements on pumps, .valves, are introduced. Some key technologies about MD are put forward.
