工作原理1、用于靜密封時的密封原理在靜密封中以O(shè)型圈應(yīng)用較多。如果設(shè)計、使用正確，O形密封圈在靜密封中可以實現(xiàn)無泄漏的密封。O形密封圈裝入密封槽后，其截面承受接觸壓縮應(yīng)力而產(chǎn)生彈性變形。對接觸面產(chǎn)生一定的初始接觸壓力Po。即使沒有介質(zhì)壓力或者壓力很小，O形密封圈靠自身的彈性力作用而也能實現(xiàn)密封；當(dāng)容腔內(nèi)充入有壓力的介質(zhì)后，在介質(zhì)壓力的作用下，O形密封圈發(fā)生位移，移向低壓側(cè)，同時其彈性變形進(jìn)一步加大，填充和封閉間隙δ。此時，坐用于密封副偶合面的接觸壓力上升為Pm：Pm=Po+Pp式中Pp——經(jīng)O型圈傳給接觸面的接觸壓力（）Pp=K·PK——壓力傳遞系數(shù)，對于橡膠制O形密封圈K=1；P——被密封液體的壓力（）。從而增加了密封效果。由于一般K≥1，所以Pm＞P。由此可見，只要O形密封圈存在初始壓力，就能實現(xiàn)無泄漏的密封。這種靠介質(zhì)本身壓力來改變O形密封圈接觸狀態(tài)，使之實現(xiàn)密封的性質(zhì)，稱為自封作用。理論上，壓縮變形即使為零，在油壓力下也能密封，但實際上O形密封圈安裝時可能會有偏心。所以，O型圈裝入密封溝槽后，其斷面一般受到7%—30%的壓縮變形。靜密封取較大的壓縮率值，動密封取較小的壓縮率值。這是因為合成橡膠在低溫下要壓縮。
