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行。氟橡膠可以抵抗油、液壓油、燃油、潤滑劑、無機酸、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。海南氟膠O型圈供應(yīng)商耐油o型圈_耐油o型圈價格_質(zhì)量耐油o型圈批發(fā)/采購/產(chǎn)地貨源。</p><div

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。

O型圈的設(shè)計與使用O型圈的設(shè)計、使用不當(dāng)會加速它的損壞，喪失密封性能。實驗表明，如密封裝置各部分設(shè)計合理，單純地提高壓力，并不會造成O型圈的破壞。在高壓、高溫的工作條件下，O型圈破壞的主要原因是O型圈材料的長久變形和O型圈被擠入密封間隙而引起的間隙咬傷，O型圈在運動時出現(xiàn)扭曲現(xiàn)象。長久變形由于O型圈密封圈用的合成橡膠材料是屬于粘彈性材料，所以初期設(shè)定的壓緊量和回彈堵塞能力經(jīng)長時間的使用，會產(chǎn)生長久變形而逐漸喪失，隨之發(fā)生泄漏。長久變形和彈力消失是O型圈失去密封性能的主要原因，以下是造成長久變形的主要原因。1）壓縮率和拉伸量與長久變形的關(guān)系2）溫度與O型圈馳張過程的關(guān)系3）介質(zhì)工作壓力與長久變形。美國杜邦氟膠O型圈、進口O型圈美國杜邦氟膠O型圈。海南氟膠O型圈供應(yīng)商</p><p
