對不同種類固定密封或動密封應(yīng)用場合，O型圈品牌，o型密封圈為設(shè)計(jì)者提供了一種既有效又經(jīng)濟(jì)的密封元件。o型圈是一種雙向作用密封元件。安裝時徑向或軸向方面的初始壓縮，賦予o型圈自身的初始密封能力。由系統(tǒng)壓力而產(chǎn)生的密封力與初始密封力合成總的密封力，它隨系統(tǒng)壓力的提高而提高。o型圈在靜密封場合，顯示了突出的作用。然而，在動態(tài)的適當(dāng)場合中，o型圈也常被應(yīng)用，但它受到密封處的速度和壓力的限制。O型密封圈標(biāo)準(zhǔn)O型密封圈是一種擠壓型密封，擠壓型密封的基本工作原理是依靠密封件發(fā)生彈性變形，在密封接觸面上造成接觸壓力，O型圈品牌，接觸壓力大于被密封介質(zhì)的內(nèi)壓，則不發(fā)生泄漏，O型圈品牌，反之則發(fā)生泄漏。在用于靜密封和動密封時，密封接觸面接觸壓力產(chǎn)生原因和計(jì)算方法不盡相同，需分別說明。蘇州思飛o型圈_O型圈_密封圈_一應(yīng)俱全。O型圈品牌</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(jì)、使用正確，O形密封圈在靜密封中可以實(shí)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(shí)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(shí)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(shí)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(shí)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?yàn)楹铣上鹉z在低溫下要壓縮。上海非標(biāo)O型圈生產(chǎn)廠家德國進(jìn)口O型圈進(jìn)口耐高溫o型圈。</p><div

</p><p> O型圈的材料主要有丁氰橡膠NBR和氟橡膠FKM，氟橡膠更適用于高溫工況。除材料之外，O型圈很重要的一個指標(biāo)的是它的硬度，一般采用邵氏硬度來表示，從60到90左右不等，數(shù)值越大表示硬度越高。在同樣壓力下，硬度越高，防擠出(變形甚至撕裂)的能力就越強(qiáng)。因此，應(yīng)選用硬度較高的O型圈。然而，市場上常見的O型圈均為丁氰橡膠制成，邵氏硬度一般O型圈的溝槽設(shè)計(jì)有相關(guān)的國家標(biāo)準(zhǔn)，主要分動密封、軸向靜密封和徑向靜密封三種。法蘭、箱蓋等的O型圈采用軸向壓緊更便于裝配和保證密封性能。另外，我國國家標(biāo)準(zhǔn)中的溝槽尺寸標(biāo)準(zhǔn)已顯落后，如國家標(biāo)準(zhǔn)中受內(nèi)壓的O型圈溝槽外徑等于O型圈外徑，而PARKER法蘭接頭的O型圈溝槽外徑小于O型圈外徑。設(shè)計(jì)時應(yīng)適當(dāng)參考國外標(biāo)準(zhǔn)。在70左右，難以滿足相當(dāng)一部分工況的要求。有O型圈的密封面不得使用平面密封膠，可以在O型圈上涂少量黃油以使其不脫落。在維修時。耐高溫o型圈_生產(chǎn)廠家_**國內(nèi)外。</p><div

壓縮率壓縮率W通常用下式表示:W=(d0-h)/d0d0:O型圈在自由狀態(tài)下的截面直徑(mm);h:O型圈槽底與被密封表面的距離(溝槽深度)，即O型圈壓縮后的截面高度(mm)在選取O形圈的壓縮率時,應(yīng)從如下3方面考慮:1.要有足夠的密封接觸面積;2.摩擦力盡量小;3.盡量避免長久變形。從以上這些因素不難發(fā)現(xiàn),他們相互之間存在矛盾。壓縮率大就可獲得大的接觸壓力，但是過大的壓縮率無疑就會增大滑動摩擦力和長久形。而壓縮率過小則可能由于密封溝槽的同軸度誤差和O形圈誤差不符合要求，消失部分壓縮量而引起泄漏。因此，在選擇O形圈的壓縮率時，要權(quán)衡各方面的因素。一般靜密封壓縮率大于動密封，但其極值應(yīng)小于25%，否則壓縮應(yīng)力明顯松弛，將產(chǎn)生過大的長久變形，在高溫工況中尤為嚴(yán)重。標(biāo)準(zhǔn)件-耐低溫O型圈-耐熱耐寒O型圈。福建丁晴橡膠O型圈圖片</p><p
