扭曲損傷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，由于造成O型圈在一周多受的摩擦力不均勻，O型圈的某些部分摩擦過(guò)大，發(fā)生扭曲。通常，斷面尺寸較小的O型圈，容易產(chǎn)生摩擦不均勻。造成扭曲（運(yùn)動(dòng)用O型圈比固定用O型圈的斷面直徑大就是這個(gè)道理。）另外，由于密封溝槽存在著同軸度偏差，密封高度不相等以及O型圈截面直徑不均勻等現(xiàn)象，可能使得O型圈的一部分壓縮過(guò)大，另一部分過(guò)小或不受壓縮。當(dāng)溝槽存在偏心即同軸偏差大于O型圈的壓縮量時(shí)，密封會(huì)完全失效。密封溝槽同軸度偏差大的另一個(gè)害處是使O形密封圈沿圓周壓縮不均。此外還有由于O型圈截面直徑、材質(zhì)硬度、潤(rùn)滑油膜厚度等的不均以及密封軸表面粗糙度等因素的影響，導(dǎo)致O型圈的一部分沿工件表面滑動(dòng)，另一部分則發(fā)生滾動(dòng)，從而造成O型圈的扭曲。運(yùn)動(dòng)使圈很容易因扭曲而損壞，這是密封裝置發(fā)生損壞和泄漏的重要原因。因此提高密封溝槽的加工精密度以及減小偏心是保證O型圈具有可靠的密封性和壽命的重要因素。安裝密封圈不應(yīng)是它處于扭曲狀態(tài)。假如在安裝時(shí)就被扭曲，則扭曲損傷就會(huì)很快發(fā)生。在工作中，扭曲現(xiàn)象會(huì)將O型圈切斷，產(chǎn)生大量漏油。湖南氟膠O型圈定制食品級(jí)o型圈-蘇州思飛專(zhuān)業(yè)生產(chǎn)密封件-大量現(xiàn)貨。</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(shí),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(zhǎng)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(guò)大的壓縮率無(wú)疑就會(huì)增大滑動(dòng)摩擦力和長(zhǎng)久形。而壓縮率過(guò)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(shí)，要權(quán)衡各方面的因素。一般靜密封壓縮率大于動(dòng)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(guò)大的長(zhǎng)久變形，在高溫工況中尤為嚴(yán)重。質(zhì)量o型圈!!新能密封o型圈!!按圖生產(chǎn)

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。

O形圈的修邊分為手工、機(jī)械和冷凍等三類(lèi):1。手工修邊。操作者手持刀具，沿著產(chǎn)品的外緣，將溢邊逐步修去。這是原始的方法。效率低、質(zhì)量難保證，特別對(duì)尺寸較小,精度要求高的O形圈難以做到徹底、于凈，而且很容易損及產(chǎn)品本體與溢邊的連接部。往往留下齒痕、缺口，從而留下漏油、漏氣等影響密封的后遺問(wèn)題。另外。手工修邊對(duì)操作熟練程度的依賴也很突出。2.機(jī)械修邊。為了提高效率和質(zhì)量，出現(xiàn)了機(jī)械修邊。常見(jiàn)的是帶旋轉(zhuǎn)刀刃的**電動(dòng)修邊機(jī)。所用的刀刃需與制品尺寸高度匹配。如果產(chǎn)品的內(nèi)外緣都有溢邊。則可設(shè)計(jì)成雙刃、多刃口。以實(shí)現(xiàn)一次完成。機(jī)械修邊的加工精度超過(guò)手工修邊，效率也有成倍提高，特別對(duì)一模多腔的產(chǎn)品而言，可以按照產(chǎn)品的排列與分布，設(shè)計(jì)出與之匹配的刀具。待產(chǎn)品出模后?？烧嫣咨?，一次完成沖切。在加熱的配合下，一次能修幾十個(gè)。關(guān)鍵是沖切溫度必須掌握好，防止過(guò)高后粘連。3.冷凍修邊。將硫化好的成品連同廢邊，在冷凍條件下進(jìn)行除邊。該技術(shù)是由日本的昭和碳酸與國(guó)內(nèi)的昭凌精密共同發(fā)明改進(jìn),幾十年來(lái)，隨著冷凍介質(zhì)的選擇、換代以及機(jī)械動(dòng)作的改進(jìn)，冷凍修邊也經(jīng)歷了幾代改進(jìn)，日臻成熟和完善，工作效率和加工質(zhì)量都有了明顯的提高。重慶丁晴橡膠O型圈價(jià)格</p><p
