O型圈的設(shè)計(jì)與使用O型圈的設(shè)計(jì)、使用不當(dāng)會(huì)加速它的損壞，喪失密封性能。實(shí)驗(yàn)表明，如密封裝置各部分設(shè)計(jì)合理，單純地提高壓力，并不會(huì)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(zhǎng)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(yùn)動(dòng)時(shí)出現(xiàn)扭曲現(xiàn)象。長(zhǎng)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(zhǎng)時(shí)間的使用，會(huì)產(chǎn)生長(zhǎng)久變形而逐漸喪失，隨之發(fā)生泄漏。長(zhǎng)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(zhǎng)久變形的主要原因。1）壓縮率和拉伸量與長(zhǎng)久變形的關(guān)系2）溫度與O型圈馳張過(guò)程的關(guān)系3）介質(zhì)工作壓力與長(zhǎng)久變形。阻燃硅膠O型圈制造廠家品牌。</p><div

O型密封圈壓縮率W的選擇應(yīng)考慮使用條件，靜密封或動(dòng)密封;靜密封又可分為徑向密封與軸向密封;徑向密封(或稱(chēng)圓柱靜密封)的泄漏間隙是徑向間隙，軸向密封(或稱(chēng)平面靜密封)的泄漏間隙是軸向間隙。軸向密封根據(jù)壓力介質(zhì)作用于O形圈的內(nèi)徑還是外徑又分受內(nèi)壓和受外壓兩種情況，內(nèi)壓增加的拉伸，外壓降低O形圈的初始拉伸。(歡迎關(guān)注:泵友圈)上述不同形式的靜密封，密封介質(zhì)對(duì)O形圈的作用方向是不同的，所以預(yù)壓力設(shè)計(jì)也不同。對(duì)于動(dòng)密封則要區(qū)分是往復(fù)運(yùn)動(dòng)密封還是旋轉(zhuǎn)運(yùn)動(dòng)密封。1.靜密封:圓柱靜密封裝置和往復(fù)運(yùn)動(dòng)式密封裝置一樣，一般取W=10%~15%;平面靜密封裝置取W=15%~30%。2.對(duì)于動(dòng)密封而言，可以分為三種情況;往復(fù)運(yùn)動(dòng)一般取W=10%~15%。旋轉(zhuǎn)運(yùn)動(dòng)密封在選取壓縮率時(shí)必須要考慮焦耳熱效應(yīng)，一般來(lái)說(shuō)，旋轉(zhuǎn)運(yùn)動(dòng)用O形圈的內(nèi)徑要比軸徑大3%-5%，外徑的壓縮率W=3%-8%。低摩擦運(yùn)動(dòng)用O型圈，為了減少摩擦阻力，一般均選取較小的壓縮率，即W=5%-8%，此外，還要考慮到介質(zhì)和溫度引起的橡膠材料膨脹。通常在給定的壓縮變形之外，允許的較大膨脹率為15%，超過(guò)這一范圍說(shuō)明材料選用不合適，應(yīng)改用其他材料的O形圈，或?qū)o定的壓縮變形率予以修正。耐高溫O型圈-蘇州思飛硅橡膠制品有限公司。寧波耐高溫O型圈圖片</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。甘肅防靜電O型圈廠商</p><p
