由于裝配時(shí)達(dá)不到墊片所需的壓緊力或由于在常期運(yùn)行中的振動(dòng)使壓緊螺栓松動(dòng)而使壓緊力降低以及由于墊片材質(zhì)的老化變形而喪失原來的彈性都會(huì)使墊片失效而產(chǎn)生泄漏。O型圈密封泵中常用的是橡膠O型圈。由于其形狀十分簡(jiǎn)單，因而制造容易，成本低廉，不論O型圈的整體尺寸有多大，其截面尺寸都很小(只有幾毫米)所以重量輕，消耗材料少，使用方法簡(jiǎn)單，安裝、拆卸方便，更為突出的優(yōu)點(diǎn)還在于O形圈具有良好的密封能力，使用范圍很寬。靜密封工作壓力可達(dá)100MPa以上，動(dòng)密封也可達(dá)30Mpa。適用溫度為-60～200℃，可滿足多種介質(zhì)的使用要求。因此在泵的設(shè)計(jì)中得到越來越廣的應(yīng)用。O形密封圈安裝在溝槽和被密封面之間，有一定壓縮量，由此產(chǎn)生的反彈力給予被密封的光滑面和溝槽底面以初始的壓縮應(yīng)力。從而起到密封作用，薊州區(qū)格蘭富機(jī)械密封NBG80-65-160。當(dāng)被密封的液體壓力增大時(shí)，O形圈的變形也隨之增大，從而傳遞給密封面的壓力也增大，密封的作用也增大。這就是O形密封圈具有良好密封能力的原因，薊州區(qū)格蘭富機(jī)械密封NBG80-65-160。O形密封圈雖然密封可靠，但如果不注意使用條件，也會(huì)發(fā)生泄漏，薊州區(qū)格蘭富機(jī)械密封NBG80-65-160，通常有以下幾種情況：1、裝O形圈的溝槽尺寸超差，尤其是深度尺寸過大時(shí)，使O形圈安裝后壓縮變形量不足而影響密封能力。河北格蘭富機(jī)械密封件。薊州區(qū)格蘭富機(jī)械密封NBG80-65-160</p><div
