补充资料:船尾轴橡胶密封
分子式:
CAS号:
性质:用于船舶尾轴的旋转密封,有封油、封水的双重作用,一般由密封元件和夹持定位部件组成,是船舶动力装置的一个重要部件。由于工作环境恶劣、安装于船外水线下,维修十分困难,对密封装置要求较高。其结构形式主要有如下5种。(1)油圈式:系由三道油圈和三道油令板组成。(2)骨架油封式:属于一种轴向阻油的接触式唇形密封,一般用3~4道油封组合而成,其中两道阻水,两道阻油。(3)浮动式密封:一般由三道橡胶骨架油封及防震衬套组成,可克服骨架油封对轴径向跳动适应性差的缺点。(4)端面密封:是由橡胶密封和金属零件组合的密封装置,常用于中型船舶。(5)辛泼莱克斯密封:其密封元件由3个唇部装有箍紧弹簧的辛泼莱克斯橡胶密封圈组成。此种密封对轴追随性好,适应面广,密封效果好,使用寿命长。
