进口O型圈虽然密封可靠,但如果不注意使用条件,也会发生泄漏,通常有以下几种情况:
1、装进口O型圈的沟槽尺寸超差,尤其是深度尺寸过大时,使进口O型圈安装后压缩变形量不足而影响密封能力。一般进口O型圈安装后压缩变形量应在18%~22%之间,截面尺寸大时压缩相对变形量较小,而截面尺寸较小时压缩相对变形量则较大。
2、进口O型圈的公称尺寸与实际安装尺寸相差太多,形成O形圈在拉伸后截面尺寸缩小的状况下工作,造成压缩变形量不足而产生泄漏。
3、密封圈型号规格表进口O型圈在安装时,由于密封面的进口没有光滑的倒角或倒圆而将进口O型圈划伤而产生泄漏。
4、进口O型圈的材质不适用于密封介质而被侵蚀后失效。5、进口O型圈使用时间太久后老化变质,弹性降低后而失效,所以在设备大修时一般都将O形圈更换。进口O型圈型号规格表
另外,进口O型圈的硬度,沟槽和密封面的粗糙度也影响O形密封圈的密封效果
泵中常用的是橡胶O型圈。由于其形状十分简单,因而制造容易,成本低廉,不论O型圈的整体尺寸有多大,其截面尺寸都很小(只有几毫米)所以重量轻,消耗材料少,使用方法简单,安装、拆卸方便,更为突出的优点还在于O形圈具有良好的密封能力,使用范围很宽。静密封工作压力可达100MPa以上,动密封也可达30Mpa。适用温度为-60~200℃,可满足多种介质的使用要求。因此在泵的设计中得到越来越广泛的应用。G3/O型圈
