Slip ring combined seal
Performance and Purpose:
Slip ring combined seal is made up of low-friction PTFE composite slip ring and O-ring. It has the advantages of friction resistance, temperature resistance, high pressure bearing ability, high linear velocity, small friction force and long use-life. And which is applicable to dynamic and static seal of hydraulic and pneumatic system in aircraft, metallurgy, petroleum, chemical, textile, food industry and so on.
由低摩擦聚四氟乙烯(PTFE)复合材料滑环与O形圈组合而成的组合密封具有耐磨、耐温、耐压、线速度高、摩擦力小和使用寿命长的特点。适用于航空、冶金、石油、化工、纺织、食品等行业的液压与气动系统的动、静密封。
Advantage
- The structure is simple, easy to install and can be used repeatedly
结构简单，安装方便，可重复安装使用
- The sealing performance is reliable and adjustable
密封性能可靠，密封性可调节
- Different types of PTFE materials(Self pressed PTFE barrel material) can be selected according to the working conditions of sealing environment
自主压制四氟桶料，可根据密封环境工况选择不同类型四氟材料
- The working life of dynamic pressure seal is 5 ~ 10 times higher than that of conventional rubber sealing products, and the highest working life can reach dozens of times
工作寿命高，动态压力密封工作寿命比常规橡胶密封制品高5~10倍，最高可达数十倍
- It can be used as oil-free lubrication seal
可作无油润滑密封
- The friction force is small, and the dynamic and static friction force are equal. The friction force is 1 / 2 ~ 1 / 4 of the O-type rubber ring, which can eliminate the "crawling" phenomenon of motion at low speed and low pressure.
摩擦力小，且动、静摩擦力相等，是O型橡胶圈的1/2~1/4，可消除低速低压下运动的“爬行”现象
