机械密封技术的发展历程及其展望

Development history and prospect of mechanical face seal technology

在过去的一百三十多年间,机械密封技术从一项无人问津的专利逐步发展为化工、石油、动力、轻工、原子能、宇航等工业领域重点关注的高精尖技术。为揭示机械密封技术发展进步的内在逻辑,追溯了其发展历程,透过其不断拓展应用领域和范围、不断提升使用性能的现象,以驱动其进步的关键逻辑思想为研究重点,剖析了各阶段机械密封技术进步的逻辑要点,再现了人们探索机械密封技术进步时的逻辑考量,并据此预测了机械密封技术的发展方向。

In the past 130 years,mechanical sealing technology has gradually developed from a no-one patent to a sophisticated technology in the fields of chemical,petroleum,power,light industry,atomic energy,aerospace and other industries.In order to reveal the internal logic of the development,development of mechanical sealing is traced,the logical points of mechanical sealing technology progress at various stages are analyzed through its continuous expansion of application fields and scope,and continuously improve the phenomenon of use performance,with the key logical ideas driving its progress as the research focus.And the logical considerations when people explore the progress of mechanical sealing technology are reproduced.Development direction of mechanical sealing technology is predicted accordingly,and unpredictable factors are also pointed out.
