KS 阶梯封
KS 阶梯封
性能及用途KS 阶梯封是由PTFE滑环和O型圈弹性体配合使用的组合密封，O型圈作为弹性体能提供足够的密封预紧力，并
对PTFE滑环的磨损起补偿作用。PTFE材料摩擦系数小，耐磨损性能极佳，PTFE滑环特殊设计的几何尺寸，使其
具有良好的抗挤出性能，同时KS阶梯封对残余油膜有“泵回吸”的作用，能有效地抑制在串联密封配置中出现的“困压”
现象。KS阶梯封特别适用于工程机械液压油缸、控制油缸、伺服系统、机床、快速响应油缸等。
优点
--静态和动态密封效果好
--抗挤出性能优越
--起动和运动摩擦力小
--起动无爬行，无粘滞
--耐磨损，可靠性高
--耐高温，耐介质范围广（取决于所选O型圈的材料）
--结构简单，便于安装
材料
标准用途
密封体：填充聚四氟乙烯 材料代码： T605
O型圈：丁腈橡胶 材料代码：N800
组件代码：T605N
对于高温及耐化学介质的使用工况，O型圈材料推荐使用氟橡胶： F800，组件代码：T605F
对于低温的适用工况，O型圈材料推荐使用耐低温丁腈橡胶：NV705，组件代码： T605NV
技术数据
标准KS阶梯封适用于工程机械液压缸、机床、注射机和压力机等
工作压力：≤40MPa
速度： ≤5m/s
温度：-40℃ to +200℃ (取决于O型圈材质)
介质：液压油、乳化液、水
重要提示：以上数据极限值，不可同时使用。例如：最大工作压力取决于材料类型、压力、温度、间隙等。在实际
使用中由于工作参数的相互影响，最大值设定的相应要低。
安装
沟槽：封闭式；开放式 (对于极限小直径和极限横截面的情况建议采用开放式沟槽)
为了避免密封件损坏，安装时密封件不要通过部件锐边并防止与安装工具锐角接触；必须去除密封件安装区域中的锐
边和毛刺；安装时应避免O型圈扭转。
