Description

一种汽轮机盘车摇杆轴密封装置 技术领域
本发明涉及一种汽轮机盘车摇杆轴，尤其涉及一种汽轮机盘车摇杆轴密封装置。
背景技术
现有技术中，汽轮机通过一副刚性联轴器与发电机相连，转子盘车安装置装于后轴承盖上，由电动机驱动，通过蜗轮蜗杆以及齿轮减速达到所需要的盘车速度，汽轮机盘车转速为4.8转/分钟，当转子的转速高于盘车速度时，盘车装置能自动退出工作位置。
当汽轮机转子需要投入盘车时，人工盘动电机转动盘，手推盘车摇杆轴转动45度至蜗轮与齿轮黏合，然后启动电动机进行电动盘车。当汽轮机冲转时，转子旋转速度超过盘车速度时，摇杆轴带动蜗轮脱离齿轮，转动45度至完全脱开位置。盘车投入和退出过程摇杆轴都需要旋转45度。摇杆轴固定在盘车机座的两端两个轴孔中，其中一侧接操作手柄，另外一侧接行程控制器。
现有技术中，因摇杆轴与盘车机座轴孔是间隙配合，其中无任何密封装置，在转子运转过程中润滑油通过摇杆轴与轴孔之间的间隙渗出至两端，流到轴承箱上，无法消除，需要定期清除。
问题是，润滑油流出至盘车机座、轴承箱上，既浪费润滑油、影响环境卫生同时又造成安全隐患。
