style="text-indent:25px">橡膠O形圈運(yùn)用不當(dāng)會(huì)加快損壞其密封功能：介質(zhì)作業(yè)壓力與持久變形。作業(yè)介質(zhì)的壓力是致使O形圈持久變形的首要要素?，F(xiàn)代液壓設(shè)備的作業(yè)壓力正日益進(jìn)步。長(zhǎng)期的高壓效果會(huì)使O形圈發(fā)作持久變形。因而，規(guī)劃時(shí)應(yīng)根據(jù)作業(yè)壓力選用恰當(dāng)?shù)哪蛪合鹉z資料。作業(yè)壓力越高，所用資料的硬度和耐高壓功能也應(yīng)越高。為了改進(jìn)O形圈資料的耐壓功能，添加資料的彈性（特別是添加資料在低溫下的彈性）、下降資料的緊縮持久變形，通常需要改進(jìn)資料的配方，參加增塑劑。可是，具有增塑劑的O密封形圈，長(zhǎng)期在作業(yè)介質(zhì)中浸泡，增塑劑會(huì)逐步被作業(yè)介質(zhì)吸收，致使O形密封圈體積縮短，甚至能夠使O形密封圈發(fā)作負(fù)緊縮（即在O形密封圈和被密封件的外表之間呈現(xiàn)空隙）。因而，在核算O形密封圈緊縮量和進(jìn)行模具規(guī)劃時(shí)，應(yīng)充沛思考到這些縮短量。應(yīng)使限制出的O形密封圈在作業(yè)介質(zhì)中浸泡5~10晝夜后仍能堅(jiān)持必要的尺度。要考慮到介質(zhì)和溫度引起的橡膠材料膨脹。</p><div
