材料介绍

  • Kintowe K780 双作用组合密封圈是适用于单活塞的紧凑型双作用密封圈，该橡胶单元有很好的抗磨损能力，适用于广泛的中载工况条件应用，该密封设计同样也适用于双活塞。

    该组合密封圈由一个橡胶密封件，两个开口保护挡圈和两个开口 “L” 型导向环组成，并对称的分置于橡胶密封单元两侧。

    丁腈橡胶密封单元设计成锯齿形多唇密封，其具有极佳的动密封性能和极低的摩檫力。当压力升高时，两个开口保护挡圈上的凸起部分能有效防挤出损害。导向环由坚固但具有塑性的聚合物制成，环上带有切口，易于安装。

    两个 “L” 形的导向表面环开有匀压槽，可以将压力平稳的传递给橡胶密封件，并能有效的防止密封圈在装配时可能产生的 “ 困压 ” 现象。
