性能指標(biāo)1.分析項目：主成分分析、圖譜分析、失效分析、全成份分析、材質(zhì)鑒定、配方還原等2.物理機(jī)械性能：密度/比重、硬度試驗、表面電阻率、拉伸性能、沖擊性能等；3.老化性能：臭氧、紫外老化、鹽霧老化、氙燈老化、碳弧燈老化、鹵素?zé)衾匣勖扑愕龋?.耐液體性能：耐潤滑油、耐汽油、耐機(jī)油、耐酸、耐堿、耐有機(jī)溶劑、耐耐水性能等；5.燃燒性能：防火阻燃、垂直燃燒、酒精噴燈燃燒、巷道丙烷燃燒、煙密度、燃燒速率等；6.適用性能：耐液壓、脈沖試驗、導(dǎo)電性能、水密性、氣密性等。材料選擇用作O形圈的材料有丁腈橡膠、羧酸腈、氟橡膠、乙丙橡膠、氫化丁腈橡膠、硅橡膠、氯丁橡膠、氟硅橡膠、聚氨酯、氯醇橡膠、丁苯橡膠、丁基橡膠、天然橡膠、乙烯/乙丙酸橡膠、聚丙烯酸酯橡膠、全氟橡膠等等。同樣一種橡膠由于配方的不同，性能指標(biāo)也有較大的變化。所以在材料欄中簡單地填寫丁腈橡膠或丁腈-40是不準(zhǔn)確的。用于O形圈的材料化工部有專門的標(biāo)準(zhǔn)，如：HG/T2579-1994、HG/T2021-1991、HG/T2333-1992、HG/T3089-2001、HB5290-1991等。HG/T2579-1994專門去掉了材料的具體類別，只給出了材料的一些性能指標(biāo)。進(jìn)口回彈性好的O型圈，請認(rèn)準(zhǔn)蘇州思飛。</p><div

橡膠O型圈安裝要求(1)檢查引入角是否符合圖紙要求，15°~30°以及D2K尺寸。(2)密封件和零件應(yīng)涂潤滑脂或潤滑液，但不得使用含固體添加劑的潤滑脂，如二硫化鉬、硫化鋅。(3)安裝前對安裝軸頸進(jìn)行外觀檢查，表面不得有飛邊毛刺、雜質(zhì)、灰塵等缺陷及刮傷。(4)安裝過程中防止O型圈碰傷，應(yīng)先用銼修平毛刺，在其通過的部位螺紋及鍵槽表面用膠帶包上再進(jìn)行安裝，可起到保護(hù)O型圈的作用。油管接頭倒角密封橡膠O型圈是一種連接面處的密封，采用O形圈將其裝配到一個通過倒角產(chǎn)生的槽中，然后通過殼體擠壓來產(chǎn)生密封。設(shè)計時主要考慮橡膠O型圈產(chǎn)品必須進(jìn)行輕微拉伸、壓縮量適當(dāng)減小、填充率適當(dāng)加大。倒角一般為15°~30°，依據(jù)工作壓力選取，壓力大時，角度要趨近于小值。反之，則取大值。倒角密封因其在接頭與液壓閥之間使用簡便，操作簡單，且制作與加工容易等特點，在油管接頭的密封過程中常被廣泛應(yīng)用。本文著重介紹密封倒角的設(shè)計及O型圈的選用。橡膠O型圈破壞的重要原因之一是在工作壓力作用下被擠入間隙內(nèi)，此間隙的允許值與工作壓力，橡膠O型圈橡膠硬度及其截面直徑d0大小有關(guān)，O型圈壓縮量的大小能直接影響到密封性能和使用壽命，壓縮量太小，密封效果不好;壓縮量太大。

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,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增大滑動摩擦力和長久形。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，要權(quán)衡各方面的因素。一般靜密封壓縮率大于動密封，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。上海O型圈訂做</p><p
