活塞杆密封系统

活塞杆密封件和缓冲密封件可保持液压缸盖和往复运动的活塞杆之间的密封接触。根据具体应用的不同，活塞杆密封系统可以包含活塞杆密封件和缓冲密封件（ 图1）或仅包含活塞杆密封件（ 图2）。 用于重型应用的活塞杆密封系统一般包含两种密封件的组合，其中缓冲密封件位于活塞杆密封件和活塞之间。活塞杆密封件确定了活塞杆直径 d 的公差。 

除了密封功能之外，活塞杆密封件还可在活塞杆上提供一层薄薄的润滑油膜，从而实现自润滑和润滑防尘密封件。润滑剂还可以抑制活塞杆表面的腐蚀。 润滑油膜必须足够薄，从而可以在回程时回到液压缸中。

活塞杆密封系统的密封类型和材料选择是一项复杂的工作，需要考虑液压缸整体设计与应用条件。 SKF提供多种不同类型、材料和各种系列和尺寸的活塞杆密封件和缓冲密封件，以适用于各种工况和应用。
