7、的耐油耐辐射、耐燃烧等性能 一、O型圈有多长的使用寿命O型圈的使用寿命主要是由O型圈的材质和使用环境（温度、压力、介质等）决定的。O型圈按材质分主要为：丁腈橡胶O型圈、氟橡胶O型圈、硅橡胶O型圈、三元乙丙橡胶O型圈、氯丁橡胶O型圈、天然橡胶O型圈等。静态O型圈密封的使用寿命明显比动态O型圈密封的使用寿命要长的多，因为有的O型圈是套在轴上需要滑动或旋转密封的，这时O型圈的使用寿命就是由与o型圈相配合的槽及孔的配合尺寸和表面粗糙度等因素决定。因此，O型圈的使用寿命很难给出确切的年限，使用不当O型圈的使用寿命可能1年或更低，使用妥当，O型圈的使用寿命可能是3年、6年或更高。二、O型圈挤出间隙O型圈挤

8、出间隙与O型圈截面直径以及材料硬度有关。通常情况下，工作压力越大，O型圈最大允许挤出间隙gmax取值越小。如果O型圈间隙g超过允许范围，就会导致O型圈挤出甚至损坏。三、主打产品之一 - O型圈我司专业生产各种规格O型圈、O型密封圈、橡胶O型圈、硅胶O型圈、氟胶O型圈、防水O型圈、耐油O型圈、耐高温O型圈、美标O型圈，日标O型圈，欧标O型圈,国标O型圈AS568O型圈，JISO型圈，PGO型圈，GBO型圈，丁腈橡胶O型圈，橡胶O型密封圈，硅胶O型密封圈,O-RING,氟胶O型密封圈，精密O型圈。我司O型圈生产所用原材料全部采用进口胶料，做工精细，产品无毛边，属于中高档产品，进口产品中价格最低一直

9、是不懈的追求。四、O型圈自身的优点 1/O型圈密封性能优良，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510倍，最高可达数十倍，在某些条件下可与密封基体同寿命；2/O型圈具有高耐磨性O型圈密封面磨损后具有自动弹性补偿功能；3/O型圈适合多种密封形式静态密封和动态密封均可适用，各种用途材料、尺寸和沟槽都已标准化，互换性非常强；4/O型圈适合多种密封形式O型圈可用于旋转运动、轴向往复运动或组合运动；5/O型圈适合多种不同的密封介质O型圈可实现对油、水、空气、煤气及各种化学介质有效的密封作用。O型圈温度使用范围广，为 60 220 ，固定使用时压力可达 1500Kg/cm2( 与补强环并用

10、)；6/O型圈适合多种密封形式O型圈静态密封和动态密封均可适用，各种用途材料、尺寸和沟槽都已标准化，互换性非常强；7/O型圈设计简单，结构小巧，装拆方便O 形圈断面结构极其简单且已形成标准化，安装更换都非常容易，密封性能可靠；8/O型圈材料品种多 有丁腈橡胶（NBR）、氟橡胶（FKM）、硅橡胶（SI）、三元乙丙橡胶（EPDM）、氯丁橡胶（CR）、丁基橡胶（BU）、聚四氟乙烯（PTFE）、天然橡胶（NR）等；9/O型圈成本低廉10/O型圈动摩擦阻力比较小O型密封圈O型圈(O-rings)是一种截面为圆形的橡胶密封圈，因其截面为O型，故称其为O型密封圈，也叫O型圈。：types: one is t
