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，但是過大的壓縮率無疑就會(huì)增大滑動(dòng)摩擦力和長久形。而壓縮率過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)生過大的長久變形，在高溫工況中尤為嚴(yán)重。安徽質(zhì)量O型圈型號(hào)阻燃硅膠O型圈制造廠家品牌。</p><div

O型圈的概述與密封原理O型橡膠圈密封圈簡稱O型圈，是一種截面形狀為圓形的橡膠圈。O型密封圈是液壓、氣動(dòng)系統(tǒng)中使用較為廣的一種密封件。O型圈有良好的密封性能，既可用于靜密封，也可用于動(dòng)密封中;不僅可單獨(dú)使用，而且是許多組合式密封裝置中的基本組成部分。它的使用范圍很寬，如果材料選擇得當(dāng)，可以滿足各種介質(zhì)和各種運(yùn)動(dòng)條件的要求。O型密封圈是一種擠壓型密封，擠壓型密封的基本工作原理是依靠密封件發(fā)生彈性變形，在密封接觸面上造成接觸壓力，接觸壓力大于被密封介質(zhì)的內(nèi)壓，則不發(fā)生泄壓縮率現(xiàn)拉伸量O型密封圈是典型的擠壓型密封。O型圈截面直徑的壓縮率和拉伸量是密封設(shè)計(jì)的主要內(nèi)容，對(duì)密封性能和使用壽命有重要意義。O型密封圈有良好的密封效果很大程度上取決于O型圈尺寸與溝槽尺寸的正確匹配，形成合理的密封圈壓縮量與拉伸量。漏，反之則發(fā)生泄漏。食品級(jí)o型圈-專業(yè)定制各種橡膠密封圈。安徽質(zhì)量O型圈型號(hào)</p><p

橡膠O型圈—硫化硫化是橡膠O型圈生產(chǎn)過程結(jié)束前的一道主要工序，一般使用平板硫化或烘箱二段硫化。在實(shí)際生產(chǎn)中，二段硫化是橡膠制品達(dá)到一定的硫化程度之后除去熱源繼續(xù)進(jìn)行加熱硫化的工藝，很多橡膠O型圈生產(chǎn)廠家選擇二段硫化。以三元乙丙橡膠O型圈為例，通常在常溫下硫化℃硫化，再提高硫化溫度至120℃繼續(xù)硫化，溫度加至150℃繼續(xù)硫化。橡膠O型圈生產(chǎn)過程中，含有硅橡膠、氟橡膠或丙烯酸酯橡膠的O型圈更適合選擇二段硫化工藝。橡膠O型圈生產(chǎn)過程主要包括烘膠、切膠，塑煉、混煉、濾膠、硫化成型等，橡膠制品廠家需要根據(jù)膠料加工工藝性能需求合理調(diào)整生產(chǎn)工藝；使用再生膠降低橡膠O型圈生產(chǎn)成本時(shí)，橡膠制品廠家還需要結(jié)合再生膠特點(diǎn)，選擇原膠與再生膠并用時(shí)，需要將原膠充分塑煉之后再與再生膠進(jìn)行混煉，尤其是天然橡膠與硬質(zhì)丁腈橡膠。安徽質(zhì)量O型圈型號(hào)</p><p
