摘　　要：非接触式机械密封由于其低磨损、高可靠性而成为密封领域研究的热点。该文通过对非接触式机械密封中流槽设计技术进行分类讨论,分别从槽深、转向和介质模态三个方面进行了论述和对比,并简要给出了其各自的使用条件及范围,以期使广大从事机械密封的工作人员对非接触式机械密封有较全面的了解,并对设计和选型有一定的帮助。Nowadays,non-contacting mechanical seals become the focus of most researchers because of its low abrasion and high reliability. Classification discussion on non-contact mechanical seal in launder design technology, this article discussed and compared the deep groove and shallow groove non-contact mechanical seal from the groove depth, steering and medium modal respectively. And presented its respective use condition and scope briefly. So as to make broad comprehensive understanding between the two types of seal for the engaged in mechanical seal staff, and beneficial to the design and type selection.
