O型圈的使用O型圈在多種液壓、氣動(dòng)件管接頭、圓筒面及法蘭面等結(jié)合處被使用。對(duì)于在運(yùn)動(dòng)過(guò)程中使用的O型圈，當(dāng)工作壓力大于，如單向受壓，就在O型圈受壓力方向的另一側(cè)設(shè)置一個(gè)擋圈;如雙向受壓，則在O型圈兩側(cè)各放一個(gè)擋圈。為了減小摩擦力，也可采用楔型擋圈。當(dāng)壓力液體從左方施加作用時(shí)，右方擋圈被推起，左方擋圈不與被密封表面接觸，因此摩擦力減小。總的來(lái)說(shuō)，采用擋圈會(huì)增大密封裝置的摩擦力，而楔型擋圈對(duì)減小這種摩擦力具有十分重要的意義。對(duì)于固定用的O型圈，當(dāng)工作壓力大于32Mpa時(shí)，也需要使用擋圈。O型圈的安裝O型圈的安裝質(zhì)量對(duì)其密封性和使用壽命均有重要的影響。泄漏問(wèn)題往往是因?yàn)榘惭b不良而造成的。安裝過(guò)程中不允許出現(xiàn)O型圈被劃傷和位置安裝不正，以及O型圈被扭曲等情況。裝配前，密封溝槽、密封配合面必須嚴(yán)格清洗;同時(shí)對(duì)O型圈裝配中要通過(guò)的表面涂敷潤(rùn)滑脂。為了防止O型圈在安裝時(shí)被尖角和螺紋等銳邊切傷或劃傷，應(yīng)在安裝的軸端和孔端留有15o~30o的引入角。當(dāng)O型圈需通過(guò)外螺紋時(shí)，應(yīng)使用**的薄壁金屬導(dǎo)套，套住外螺紋;如果O型圈需通過(guò)孔口時(shí)，應(yīng)使孔口倒成相應(yīng)的斜角形狀，以防O型圈被劃傷。

磨粒磨損現(xiàn)象當(dāng)密封的間隙具有相對(duì)運(yùn)動(dòng)時(shí)，工作環(huán)境中的灰塵和沙粒等被粘附在活塞桿表面，并隨著活塞桿的往復(fù)運(yùn)動(dòng)與油膜一起被帶入缸內(nèi)，成為侵入O形密封圈表面的磨粒，加速O型圈的磨損，以致其失去密封性。為了避免這種情況發(fā)生，在往復(fù)運(yùn)動(dòng)式密封裝置的外伸軸端處必須使用防塵圈?；瑒?dòng)表面對(duì)O型圈的影響滑動(dòng)表面的粗糙度是影響O型圈表面摩擦與磨損的直接因素。一般地說(shuō)，表面光潔摩擦與磨損就小，所以滑動(dòng)表面的粗糙度數(shù)值往往很低（μm）。但是，試驗(yàn)表明，表面粗糙過(guò)低（Ra低于μm）又會(huì)給摩擦與磨損帶來(lái)不利的影響。這是因?yàn)槲⑿〉谋砻姘纪共黄?，可以保持必要的?rùn)滑油膜。因此要選擇適當(dāng)?shù)谋砻嬉??；瑒?dòng)表面的材質(zhì)對(duì)O型圈的壽命也有影響。滑動(dòng)表面材質(zhì)的硬度越大、耐磨性越高、保持光潔的能力就越強(qiáng)，O型圈的壽命也就越長(zhǎng)。這也是液壓缸活塞桿表面鍍鉻的重要原因。同理可以解釋具有同樣粗糙度的用銅、鋁合金制成的滑動(dòng)表面比鋼制滑動(dòng)表面對(duì)密封圈的摩擦與磨損更為嚴(yán)重，低硬度、大壓縮量的密封圈不如高硬度、小壓縮量的密封圈耐用的情況。歐盟RoHS2.0O型圈耐高溫O型圈氟膠O型圈規(guī)格。</p><div

注意事項(xiàng)氟橡膠的主要特性是耐高溫和耐化學(xué)腐蝕，并有很好的抗老化和抗臭氧的性能，且滲氣度也非常低。即使在非常惡劣的工作條件下，仍然有非常好的耐磨性。氟橡膠能承受+200度或以下的工作溫度，也能允許短時(shí)間無(wú)油情況下的運(yùn)行。氟橡膠可以抵抗油、液壓油、燃油、潤(rùn)滑劑、無(wú)機(jī)酸、脂族烴和芳族烴等，但在有酯、醚、酮、某些胺和高溫的氟水氫等化合物的情況下，不應(yīng)使用氟橡膠。在正常工作條件和工作溫度在+200度以下，氟橡膠是非常穩(wěn)定和無(wú)害的。但遇到300度以上高溫時(shí)，如火焰，氟橡膠會(huì)釋放出有害的氣體。吸入這些氣體或進(jìn)入眼睛會(huì)對(duì)人體健康造成損害。氟橡膠密封圈一旦被加熱到300度以上的高溫，即使在冷卻后處理也會(huì)有危險(xiǎn)，因此絕不可直接對(duì)皮膚的任何接觸。阻燃o(jì)型圈-阻燃o(jì)型圈批發(fā)廠家、廠家比價(jià)、質(zhì)量供應(yīng)商。重慶專業(yè)O型圈批發(fā)</p><p
