用于往復(fù)運(yùn)動(dòng)密封時(shí)的密封原理在液壓轉(zhuǎn)動(dòng)、氣動(dòng)元件與系統(tǒng)中，往復(fù)動(dòng)密封是一種常見(jiàn)的密封要求。動(dòng)力缸活塞與缸體、活塞干預(yù)缸蓋以及各類(lèi)滑閥上都用到往復(fù)運(yùn)動(dòng)密封。縫隙由圓柱桿與圓柱孔形成，桿在圓柱孔內(nèi)軸向運(yùn)動(dòng)。密封作用限制流體的軸向泄漏。用作往復(fù)運(yùn)動(dòng)密封時(shí)，O型圈的預(yù)密封效果和自密封作用與靜密封一樣，并且由于O型圈自身的彈力，而具有磨損后自動(dòng)補(bǔ)償?shù)哪芰?。但由于液體介質(zhì)密封時(shí)，由于桿運(yùn)動(dòng)速度、液體的壓力、粘度的作用，情況比靜密封復(fù)雜。當(dāng)液體在壓力作用下，液體分子與金屬表面互相作用，油液中所含的“極性分子”在金屬表面上緊密而整齊的排列，沿滑移面與密封件間形成一個(gè)強(qiáng)固的邊界層油膜，并且對(duì)滑移面產(chǎn)生極大的附著力。該液體薄膜始終存在于密封件與往復(fù)運(yùn)動(dòng)面之間，它亦起一定的密封作用，并且對(duì)運(yùn)動(dòng)密封面的潤(rùn)滑是非常重要的。但是對(duì)泄漏來(lái)講是有害的。但往復(fù)運(yùn)動(dòng)的軸向外拖出時(shí)，軸上的液體薄膜便與軸一起拉出，由于密封件的“擦拭”作用，當(dāng)往復(fù)運(yùn)動(dòng)的軸縮回時(shí)，該液體薄膜便被密封元件阻留在外面。隨著往復(fù)運(yùn)動(dòng)行程次數(shù)增多，阻留在外面的液體就越多，常州橡膠O型圈，后形成油滴，這就是往復(fù)運(yùn)動(dòng)式密封裝置的泄漏，常州橡膠O型圈，常州橡膠O型圈。由于液壓油的粘度隨著溫度的升高而降低。注射器**O型圈,進(jìn)口透明環(huán)保硅膠O型圈。常州橡膠O型圈</p><div

O型密封圈密封性能優(yōu)良，工作壽命高，在某些條件下可與密封基體同壽命。O型密封圈適用于裝在各種機(jī)械設(shè)備上，在規(guī)定的溫度、壓力、以及不同的液體和氣體介質(zhì)中，于靜止或運(yùn)動(dòng)狀態(tài)下起密封作用。在機(jī)床、船舶、汽車(chē)、航空航天設(shè)備、冶金機(jī)械、化工機(jī)械、工程機(jī)械、建筑機(jī)械、礦山機(jī)械、石油機(jī)械、塑料機(jī)械、農(nóng)業(yè)機(jī)械、以及各類(lèi)儀器儀表上，大量應(yīng)用著各種類(lèi)型的密封元件。O型密封圈主要用于靜密封和往復(fù)運(yùn)動(dòng)密封。用于旋轉(zhuǎn)運(yùn)動(dòng)密封時(shí)，只用于低速回轉(zhuǎn)密封裝置。O型密封圈一般安裝在外圓或內(nèi)圓上截面為矩形的溝槽內(nèi)起密封作用。O型密封圈在耐油、酸堿、磨、化學(xué)侵蝕等環(huán)境依然起到良好密封、減震作用。因此，O型密封圈是液壓與氣壓傳動(dòng)系統(tǒng)中使用較多的一種密封件。常州橡膠O型圈O型密封圈

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。

O型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(gè)指標(biāo)的是它的硬度，一般采用邵氏硬度來(lái)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。然而，市場(chǎng)上常見(jiàn)的O型圈均為丁氰橡膠制成，邵氏硬度一般O型圈的溝槽設(shè)計(jì)有相關(guān)的國(guó)家標(biāo)準(zhǔn)，主要分動(dòng)密封、軸向靜密封和徑向靜密封三種。法蘭、箱蓋等的O型圈采用軸向壓緊更便于裝配和保證密封性能。另外，我國(guó)國(guó)家標(biāo)準(zhǔn)中的溝槽尺寸標(biāo)準(zhǔn)已顯落后，如國(guó)家標(biāo)準(zhǔn)中受內(nèi)壓的O型圈溝槽外徑等于O型圈外徑，而PARKER法蘭接頭的O型圈溝槽外徑小于O型圈外徑。設(shè)計(jì)時(shí)應(yīng)適當(dāng)參考國(guó)外標(biāo)準(zhǔn)。在70左右，難以滿(mǎn)足相當(dāng)一部分工況的要求。有O型圈的密封面不得使用平面密封膠，可以在O型圈上涂少量黃油以使其不脫落。在維修時(shí)。常州橡膠O型圈</p><p
