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，湖北防靜電O型圈定制，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?yàn)镺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，湖北防靜電O型圈定制，而且O型圈本身的抗拒能力原來就能阻止扭曲，湖北防靜電O型圈定制。摩擦力的分布也趨向保持O型圈在其溝槽中靜止不動，因?yàn)殪o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。

磨粒磨損現(xiàn)象當(dāng)密封的間隙具有相對運(yùn)動時，工作環(huán)境中的灰塵和沙粒等被粘附在活塞桿表面，并隨著活塞桿的往復(fù)運(yùn)動與油膜一起被帶入缸內(nèi)，成為侵入O形密封圈表面的磨粒，加速O型圈的磨損，以致其失去密封性。為了避免這種情況發(fā)生，在往復(fù)運(yùn)動式密封裝置的外伸軸端處必須使用防塵圈。滑動表面對O型圈的影響滑動表面的粗糙度是影響O型圈表面摩擦與磨損的直接因素。一般地說，表面光潔摩擦與磨損就小，所以滑動表面的粗糙度數(shù)值往往很低（μm）。但是，試驗(yàn)表明，表面粗糙過低（Ra低于μm）又會給摩擦與磨損帶來不利的影響。這是因?yàn)槲⑿〉谋砻姘纪共黄?，可以保持必要的潤滑油膜。因此要選擇適當(dāng)?shù)谋砻嬉?。滑動表面的材質(zhì)對O型圈的壽命也有影響。滑動表面材質(zhì)的硬度越大、耐磨性越高、保持光潔的能力就越強(qiáng)，O型圈的壽命也就越長。這也是液壓缸活塞桿表面鍍鉻的重要原因。同理可以解釋具有同樣粗糙度的用銅、鋁合金制成的滑動表面比鋼制滑動表面對密封圈的摩擦與磨損更為嚴(yán)重，低硬度、大壓縮量的密封圈不如高硬度、小壓縮量的密封圈耐用的情況。 </p><p> 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。耐高溫o型圈_專業(yè)生產(chǎn)廠家。</p><div

不同膠種的橡膠O型圈生產(chǎn)工藝不同橡膠O型圈適用于各種動、靜態(tài)密封，在油、水、氣、化學(xué)介質(zhì)或其它混合介質(zhì)中長期使用需要選擇合適的橡膠原料；理論上O型圈生產(chǎn)工藝基本一致，但由于不同種類的橡膠工藝性能不同，因此天然橡膠O型圈、各類合成橡膠O型圈與再生橡膠O型圈某些生產(chǎn)工藝存在一定差異。橡膠O型圈—塑煉目前橡膠O型圈生產(chǎn)中常用的橡膠品種有天然橡膠、丁腈橡膠、丁基橡膠、三元乙丙橡膠、硅氟橡膠等等，其中天然橡膠、丁苯橡膠與硬質(zhì)丁腈橡膠用于橡膠O型圈生產(chǎn)過程中需要進(jìn)行塑煉，其他種類的合成橡膠不需要進(jìn)行塑煉；再生膠作為原膠的低價替代原料，以廢橡膠、廢舊橡膠制品為原料加工而成，可塑性、流動性優(yōu)異，基本無需塑煉。橡膠O型圈所用膠料混煉可以選擇開煉或密煉，再生橡膠的塑煉、混煉通常在密煉機(jī)中進(jìn)行。橡膠混煉膠是O型圈HYL16Y6Y2L-SJ的半成品，其質(zhì)量直接影響O型圈產(chǎn)品質(zhì)量，因此橡膠制品廠家需要根據(jù)橡膠的加工特點(diǎn)合理調(diào)節(jié)混煉工藝條件，包括混煉時間、混煉溫度等等。湖北防靜電O型圈定制</p><p
