O型圈材料的壓縮長久變形率與溫度有關(guān)。當(dāng)變形率在40%或更大時，即會出現(xiàn)泄漏，所以幾種膠料的耐熱性界限為：丁腈橡膠70℃，三元乙丙橡膠100℃，氟橡膠140℃。因此各國對O型圈的長久變形作了規(guī)定。中國標(biāo)準(zhǔn)橡膠材料的O型圈在不同溫度下的尺寸變化見表。同一材料的O型圈，在同一溫度下，截面直徑大的O型圈壓縮長久變形率較低。在油中的情況就不同了。由于此時O型圈不與氧氣接觸，般發(fā)生在動密封狀態(tài)。O型圈如果裝配的妥善，并且使用條件適當(dāng)，一般不大容易在往復(fù)運(yùn)動狀態(tài)下產(chǎn)生滾動或扭曲，因為O型圈與溝槽的接觸面積大于在滑動表面上的摩擦接觸面積，而且O型圈本身的抗拒能力原來就能阻止扭曲。摩擦力的分布也趨向保持O型圈在其溝槽中靜止不動，因為靜摩擦大于滑動摩擦，而且溝槽表面的粗糙度一般不如滑動表面的粗糙度。 </p> <p> <br /> </p> <p> <br /> </p><p> 注意事項氟橡膠的主要特性是耐高溫和耐化學(xué)腐蝕，并有很好的抗老化和抗臭氧的性能，且滲氣度也非常低。即使在非常惡劣的工作條件下，仍然有非常好的耐磨性。氟橡膠能承受+200度或以下的工作溫度，也能允許短時間無油情況下的運(yùn)行。氟橡膠可以抵抗油、液壓油、燃油、潤滑劑、無機(jī)酸、脂族烴和芳族烴等，但在有酯、醚、酮、某些胺和高溫的氟水氫等化合物的情況下，不應(yīng)使用氟橡膠。在正常工作條件和工作溫度在+200度以下，氟橡膠是非常穩(wěn)定和無害的。但遇到300度以上高溫時，如火焰，氟橡膠會釋放出有害的氣體。吸入這些氣體或進(jìn)入眼睛會對人體健康造成損害。氟橡膠密封圈一旦被加熱到300度以上的高溫，即使在冷卻后處理也會有危險，因此絕不可直接對皮膚的任何接觸。

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。

摩擦力與O型圈的應(yīng)用在動密封裝置中，摩擦與磨損是O型圈損壞的重要影響因素。磨損程度主要取決于摩擦力的大小。當(dāng)液體壓力微小時，O型圈摩擦力的大小取決于它的預(yù)壓縮量。當(dāng)工作液體承受壓力時，摩擦力隨之工作壓力的增加而增大。在工作壓力小于20MPa的情況下，近似地呈線形關(guān)系。壓力大于20MPa時，隨著壓力的增加，O型圈與金屬表面接觸面積的增加也逐漸緩慢，摩擦力的增加也相應(yīng)緩慢。在正常情況下，O型圈的使用壽命隨著液體壓力的升高將會近似的呈平方關(guān)系而減小。摩擦力的增加，使得旋轉(zhuǎn)或往復(fù)運(yùn)動的軸與O形密封圈之間產(chǎn)生大量的摩擦熱。由于多數(shù)O型圈都是用橡膠制成的，導(dǎo)熱性極差。因此，摩擦熱就會引起橡膠的老化，導(dǎo)致O型圈實效，破壞其密封性能。摩擦還會引起O型圈表面損傷，使壓縮量減小。嚴(yán)重的摩擦?xí)芸煲餙型圈的表面損壞，失去密封性。作氣動往復(fù)運(yùn)動用密封時，摩擦熱還會引起粘著，造成摩擦力進(jìn)一步增加。運(yùn)動用密封在低速運(yùn)動時，摩擦阻力還是引起爬行的一個因素，影響元件和系統(tǒng)的工作性能。所以對運(yùn)動密封來說，摩擦性是重要性能之一。摩擦系數(shù)是摩擦特性的一個評價指標(biāo)，合成橡膠摩擦系數(shù)較大，由于密封在運(yùn)動狀態(tài)時。上海加工O型圈生產(chǎn)廠家</p><p
