回转窑窑尾密封的安装探讨

回转窑密封安装质量直接影响着密封的使用效果、寿命和回转窑的运转率。安装窑尾密封存在的主要问题是密封处的筒体径向跳动值过大，密封的找正非常困难。作者以轴向迷宫式密封和径向接触式密封为例，介绍了安装技巧和要点。其中，轴向迷宫式密封的安装关键是找准窑尾筒体最凸点，静、动圈及窑尾密封外罩等设施的安装方法；径向接触式密封的安装关键有：遵循合理的安装顺序以及动摩擦圈的安装技术等。

Discussion on installing seal of rotary kiln back end

The quality of kiln's seal installation will have direct influences not only on the effect and service life of the seal, but also the operating factor of the kiln. Too high radial shake value of kiln shell is the main problem on installation of kiln rear's seal, and the alignment of seal is too difficult. The author introduced installation technology and skill with the examples of axial labyrinth seal and radial contact seal. The key of installing axial labyrinth seal is to find the most bulgy point, the installing method of kiln rear sealing hood and static & dynamic ring; The key of installing radial contact seal is to follow correct installation order and to control the technology of dynamic friction ring,etc.
