供应特瑞堡2K型特康斯特封

品牌:瑞典特瑞堡TRELLEBORG（原宝色霞板Busak+Shamban）

品名:德国K型特康斯特封&2K型特康斯特封TurconStepseal2K

说明

2K型斯特封的密封性能是由密封件的液动力特性产生的。典型的斯特封密封件边缘在高压侧产生很陡的接触压力梯度，而在低压侧产生较平缓的接触压力梯度。这种受控的压力梯度使得在伸出行程时附着在活塞杆上的油液少，在返回行程时活塞杆上残留的油膜又会由于“泵回吸”作用而重新返回进入系统。它进一步改善了2K型斯特封在恶劣工况下（如40MPa以上）的特性。O形圈卸荷倒角减轻了在密封件上的载荷，因此与活塞杆的接触是的，并且改善了在高压下的密封性能。特殊设计的“高抬起”后跟部倒角减少了其被挤出的危险，满足了用户希望加大径向配合间隙和放宽加工公差的要求。2K型斯特封具有良好的静态和动态密封性能，并且有效地抑制了通常在串联密封配置中出现的“困压”现象。

优点

-静态和动态密封效果好；抗挤出性能优越，满足放宽加工公差需求；摩擦小，效率高；起动无爬行，无粘滞；非常耐磨损，工作可靠性高；使用温度范围宽，耐化学性好（取决于所选O形圈的材料）；安装简单，密封边缘不变形；适用于直径达2,600mm的活塞杆。
