硬度選擇O形圈硬度的選擇是比較重要的。如某電站水泵水輪機(jī)硬度為70（Shore）密封圈，常常剝落，甚至橫向切斷，后采用85～90（Shore）的密封圈，效果理想。硬度低，安裝方便，但容易出現(xiàn)剝落、安裝損傷、擠出甚至壓力。硬度過(guò)高，安裝不方便。通常O形圈硬度40～90IRHD，但在使用中一般70IRHD是比較合適的，對(duì)于硅橡膠是例外，一般使用60IRHD。.O形圈的修整未硫化O形圈膠料在高溫、壓力下為粘稠流體，而到了模壓硫化階段，膠料迅速充滿模腔，其多余的部分(為了防止缺膠，填充在模腔中的膠料，肯定保持一定的過(guò)量)溢出硫化，便形成了溢膠(也稱廢邊、飛邊)。溢邊一旦形成，為使外觀整齊、美觀，必須除去，這一工序習(xí)稱修邊。對(duì)修邊的要求是尺寸精確、外觀整齊。在實(shí)際生產(chǎn)中。產(chǎn)品的修邊往往費(fèi)時(shí)、耗工，對(duì)于要求嚴(yán)的產(chǎn)品，在修邊時(shí)稍有不慎即可能出廢次，必須謹(jǐn)慎對(duì)待。一般來(lái)說(shuō)，產(chǎn)品的尺寸規(guī)格越小、構(gòu)形越復(fù)雜，修邊的難度越高，廢品也越多。 </p><p> 引起扭曲損傷的原因很多，其中主要的是由于活塞、活塞桿和缸筒的間隙不均勻、偏心過(guò)大、O型圈斷面直徑不均勻等造成，為了防止O型圈的扭曲損傷，在設(shè)計(jì)時(shí)應(yīng)注意以下幾點(diǎn)：1）O型圈安裝溝槽的同心度大小，應(yīng)從加工方便和不產(chǎn)生扭曲現(xiàn)象兩個(gè)方面來(lái)考慮。2）O型圈斷面尺寸應(yīng)均勻，并且在每次安裝時(shí)都應(yīng)在密封部位充分涂抹潤(rùn)滑油或潤(rùn)滑脂。有時(shí)也可以采用浸透潤(rùn)滑油的氈圈式加油裝置。3）加大O型圈的截面直徑，動(dòng)密封用O形密封圈的截面直徑一般應(yīng)大于靜密封用O型圈；此外，O型圈應(yīng)避免用作大直徑活塞的密封。4）在低壓下也產(chǎn)生扭曲損傷時(shí)，可使用密封圈保護(hù)擋圈。5）降低缸筒和活塞桿的表面粗糙度。6）采用低摩擦系數(shù)的材料制作O形密封圈。7）可用不易產(chǎn)生扭曲現(xiàn)象的密封圈代替O型圈。美國(guó)杜邦氟膠O型圈、進(jìn)口O型圈美國(guó)杜邦氟膠O型圈。</p><div

O型圈材料的壓縮長(zhǎng)久變形率與溫度有關(guān)。當(dāng)變形率在40%或更大時(shí)，即會(huì)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(guó)對(duì)O型圈的長(zhǎng)久變形作了規(guī)定。中國(guó)標(biāo)準(zhǔn)橡膠材料的O型圈在不同溫度下的尺寸變化見(jiàn)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(zhǎng)久變形率較低。在油中的情況就不同了。由于此時(shí)O型圈不與氧氣接觸，般發(fā)生在動(dòng)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(dòng)狀態(tài)下產(chǎn)生滾動(dòng)或扭曲，因?yàn)镺型圈與溝槽的接觸面積大于在滑動(dòng)表面上的摩擦接觸面積，而且O型圈本身的抗拒能力原來(lái)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(dòng)，因?yàn)殪o摩擦大于滑動(dòng)摩擦，而且溝槽表面的粗糙度一般不如滑動(dòng)表面的粗糙度。

磨粒磨損現(xiàn)象當(dāng)密封的間隙具有相對(duì)運(yùn)動(dòng)時(shí)，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(dòng)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(dòng)式密封裝置的外伸軸端處必須使用防塵圈。滑動(dòng)表面對(duì)O型圈的影響滑動(dòng)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(shuō)，表面光潔摩擦與磨損就小，所以滑動(dòng)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(guò)低（Ra低于μm）又會(huì)給摩擦與磨損帶來(lái)不利的影響。這是因?yàn)槲⑿〉谋砻姘纪共黄?，可以保持必要的?rùn)滑油膜。因此要選擇適當(dāng)?shù)谋砻嬉??；瑒?dòng)表面的材質(zhì)對(duì)O型圈的壽命也有影響。滑動(dòng)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(zhǎng)。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(dòng)表面比鋼制滑動(dòng)表面對(duì)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。福建O型圈訂做</p><p
