O型橡膠圈是具有圓形截面的環(huán)行橡膠橡膠圈，主要用于機(jī)械部件在靜態(tài)條件下防止液體和氣體介質(zhì)的泄露。在某些情況下，它還能用作軸向往復(fù)運(yùn)動和低速旋轉(zhuǎn)運(yùn)動的動態(tài)密封元件。根據(jù)不同的條件，可分別選擇不同的材料與之相適應(yīng).。對不同種類固定密封或動密封應(yīng)用場合，O型橡膠圈為設(shè)計者提供了一種既有效又經(jīng)濟(jì)的密封元件。O 形圈是安裝在溝槽中、適量壓縮的 O 形截面的密封環(huán)。在各種動密封或靜密封的應(yīng)用中，O形圈是一種有效且經(jīng)濟(jì)的密封元件。河北復(fù)合橡膠密封件定制廠家橡膠密封件密封性能好，防水不漏，環(huán)保無毒。</p><div style="width:100%;text-align: center;"><img style="max-width:

style="text-indent:25px">橡膠密封件普遍地應(yīng)用于各行各業(yè)。橡膠密封件一旦失效，輕則使密封設(shè)備不能正常工作、造成經(jīng)濟(jì)損失；重則會造成人身傷亡事故。橡膠密封件的失效不僅可以幫助找出問題所在便于以后采取相應(yīng)的預(yù)防措施，還可幫助客戶和密封件生產(chǎn)商改進(jìn)現(xiàn)有技術(shù)，取得雙贏。設(shè)計錯誤通常是由於設(shè)計人員對產(chǎn)品認(rèn)識不足造成的。密封件承受的壓力估計不足、對密封面上接觸應(yīng)力分布的認(rèn)識有誤、安放密封件的溝槽設(shè)計不合理等。有限元分析(FEA)常常被用來輔助密封件的設(shè)計和失效分析。我們曾為某美國客戶做過一個密封件，該密封件以塑料為主體，局部包上橡膠。客戶在檢測零件的過程中發(fā)現(xiàn)，塑料部分在測試時容易破裂，從而得出結(jié)論是：塑料件在二次成型時(即將橡膠包覆在塑料件上)被損壞了。經(jīng)我們分析後發(fā)現(xiàn)，塑料件都是在一個地方破裂的。通過有限元分析，我們發(fā)現(xiàn)，塑料件的破損部位實際上是密封件受到較大應(yīng)力的地方，此處應(yīng)力已經(jīng)遠(yuǎn)遠(yuǎn)超過塑料所能承受的。</p><p style="text-indent:25px">型圈是密封中較常用的一種密封件。但由于選用、溝槽設(shè)計、加工和裝配上的不當(dāng)，常常造成漏油故障，可謂是小件壞大事。選用O型圈時，首先應(yīng)盡量選用新國標(biāo)，線徑2.65和3.55的使用較為普遍，在外徑大于30左右，結(jié)構(gòu)尺寸允許的情況下，盡量選用線徑3.55的O型圈，以達(dá)到更大的壓縮量和接觸面積。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。但是，市場上常見的O型圈均為丁氰橡膠制成，邵氏硬度一般在70左右，難以滿足相當(dāng)一部分工況的要求。O型橡膠圈是一種截面為圓形的橡膠圈，因其截面為O型，故稱其為O型橡膠圈。</p><div

style="text-indent:25px">橡膠墊片有模壓的，也有切割的，模壓是利用液壓成型機(jī)和模具壓制而成，切割的是利用墊片切割機(jī)切割出來的，相比而言模壓生料，但是比較單一，一副模具只可以做出一種墊片，墊片切割機(jī)切得就可以在1500nm范圍內(nèi)任意尺寸切割，但是對板材的利用率不是很高。橡膠減震墊，顧名思義就是用來控制橡膠吸震后反彈時的來自外界的沖擊震蕩，現(xiàn)在市面上的減震器材基本上都是橡膠制造的，合格質(zhì)量的橡膠減震墊應(yīng)從使用的動態(tài)特性、耐性變性、耐久性以及加工性能等綜合能力來看。橡膠減震墊的特點(diǎn)是既有高彈性，又有高黏性。橡膠的彈性是由其卷曲分子構(gòu)象的變化產(chǎn)生的，橡膠分子間相互作用會妨礙分子鏈的運(yùn)動，從而表現(xiàn)出黏性阻尼的特點(diǎn)，以致應(yīng)力與應(yīng)變往往處于不平衡狀態(tài)。橡膠可分為硬膠和軟膠，生膠和混煉膠。河北復(fù)合橡膠密封件定制廠家</p><p style="text-indent:25px">在實際的需要用到橡膠密封件的產(chǎn)品生產(chǎn)中，正確的選擇橡膠密封件是很重要的。河北復(fù)合橡膠密封件定制廠家</p><p style="text-indent:25px">O形橡膠密封圈工作環(huán)境復(fù)雜多樣，就要求其膠料具有某些特殊的性能。在液壓系統(tǒng)中，要求具有良好的耐油性、耐溫性、低的壓縮長久變形和一定的拉伸強(qiáng)度。作為動態(tài)密封，除了具有要求之外，膠料還應(yīng)具有較好的耐磨性和抗撕裂性能。用于特殊介質(zhì)的密封則要求膠料在介質(zhì)中的體積變化和硬度變化較小?？傊?，配方設(shè)計應(yīng)根據(jù)具體的工作條件、介質(zhì)種類、使用溫度、工作壓力和應(yīng)用狀態(tài)等綜合考慮。 O形密封圈膠料加工：目前，O形橡膠密封圈的制作方法還是主要用過模壓法生產(chǎn)為主，其中模壓制品的硫化方法主要有平板模壓、傳遞模壓和注射模壓三種。平板模壓法歷史較悠久。傳遞模壓約在20世紀(jì)50年代前后開始使用，而往射模壓則自60年代起逐步由塑料工業(yè)進(jìn)人橡膠工業(yè)。當(dāng)前發(fā)展趨勢是逐步發(fā)展注壓法，但由于各自適應(yīng)的范圍不同。三者共存并獲得發(fā)展仍是現(xiàn)實。O形密封圈按其特點(diǎn)仍以平板模壓為主要成型方法。河北復(fù)合橡膠密封件定制廠家</p><p>
