磁力传动与绝对密封

磁力传动应用永磁传动原理，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动回转部件，变动密封为静密封，实现了零泄漏和绝对密封，文章揭示了传动与密封原理，综述了国内外磁力驱动泵的生产与市场情况，简介了该项技术应用于泵、阀、釜中的研究成果。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。

Magnetic Driving and Absolute Seals

The magnetic driving, which is derived from the permanent magnetical principle, transmits rotator to closed vessels and realizes no-mechanical connection of driving and driven machine. It also changes dynamic seal into static one and achieves absolute seal. The principle of driving and seal is explained. The manufacture and market of the magnetic pumps are summarized. The researching results show that applying magnetic driving to pumps, valves and reactors is abstracted. Some key technology about MDS is put forward.
