磨粒磨損現(xiàn)象當(dāng)密封的間隙具有相對運動時，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)運動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)運動式密封裝置的外伸軸端處必須使用防塵圈。滑動表面對O型圈的影響滑動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，表面光潔摩擦與磨損就小，所以滑動表面的粗糙度數(shù)值往往很低（μm）。但是，試驗表明，表面粗糙過低（Ra低于μm）又會給摩擦與磨損帶來不利的影響。這是因為微小的表面凹凸不平，可以保持必要的潤滑油膜。因此要選擇適當(dāng)?shù)谋砻嬉蟆；瑒颖砻娴牟馁|(zhì)對O型圈的壽命也有影響?；瑒颖砻娌馁|(zhì)的硬度越大、耐磨性越高、保持光潔的能力就越強，O型圈的壽命也就越長。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、鋁合金制成的滑動表面比鋼制滑動表面對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。橡膠O型圈供應(yīng)商o型密封圈型號-nbr橡膠耐油o型圈-蘇州思飛。</p><div

摩擦力與O型圈的應(yīng)用在動密封裝置中，摩擦與磨損是O型圈損壞的重要影響因素。磨損程度主要取決于摩擦力的大小。當(dāng)液體壓力微小時，O型圈摩擦力的大小取決于它的預(yù)壓縮量。當(dāng)工作液體承受壓力時，摩擦力隨之工作壓力的增加而增大。在工作壓力小于20MPa的情況下，近似地呈線形關(guān)系。壓力大于20MPa時，隨著壓力的增加，O型圈與金屬表面接觸面積的增加也逐漸緩慢，摩擦力的增加也相應(yīng)緩慢。在正常情況下，O型圈的使用壽命隨著液體壓力的升高將會近似的呈平方關(guān)系而減小。摩擦力的增加，使得旋轉(zhuǎn)或往復(fù)運動的軸與O形密封圈之間產(chǎn)生大量的摩擦熱。由于多數(shù)O型圈都是用橡膠制成的，導(dǎo)熱性極差。因此，摩擦熱就會引起橡膠的老化，導(dǎo)致O型圈實效，破壞其密封性能。摩擦還會引起O型圈表面損傷，使壓縮量減小。嚴(yán)重的摩擦?xí)芸煲餙型圈的表面損壞，失去密封性。作氣動往復(fù)運動用密封時，摩擦熱還會引起粘著，造成摩擦力進(jìn)一步增加。運動用密封在低速運動時，摩擦阻力還是引起爬行的一個因素，影響元件和系統(tǒng)的工作性能。所以對運動密封來說，摩擦性是重要性能之一。摩擦系數(shù)是摩擦特性的一個評價指標(biāo)，合成橡膠摩擦系數(shù)較大，由于密封在運動狀態(tài)時。

注意事項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，也能允許短時間無油情況下的運行。氟橡膠可以抵抗油、液壓油、燃油、潤滑劑、無機酸、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)定和無害的。但遇到300度以上高溫時，如火焰，氟橡膠會釋放出有害的氣體。吸入這些氣體或進(jìn)入眼睛會對人體健康造成損害。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有危險，因此絕不可直接對皮膚的任何接觸。【阻燃o(jì)型圈】采購批發(fā)市場質(zhì)量阻燃o(jì)型圈價格/品牌/廠商。云南加工O型圈圖片</p><p

引起扭曲損傷的原因很多，其中主要的是由于活塞、活塞桿和缸筒的間隙不均勻、偏心過大、O型圈斷面直徑不均勻等造成，為了防止O型圈的扭曲損傷，在設(shè)計時應(yīng)注意以下幾點：1）O型圈安裝溝槽的同心度大小，應(yīng)從加工方便和不產(chǎn)生扭曲現(xiàn)象兩個方面來考慮。2）O型圈斷面尺寸應(yīng)均勻，并且在每次安裝時都應(yīng)在密封部位充分涂抹潤滑油或潤滑脂。有時也可以采用浸透潤滑油的氈圈式加油裝置。3）加大O型圈的截面直徑，動密封用O形密封圈的截面直徑一般應(yīng)大于靜密封用O型圈；此外，O型圈應(yīng)避免用作大直徑活塞的密封。4）在低壓下也產(chǎn)生扭曲損傷時，可使用密封圈保護(hù)擋圈。5）降低缸筒和活塞桿的表面粗糙度。6）采用低摩擦系數(shù)的材料制作O形密封圈。7）可用不易產(chǎn)生扭曲現(xiàn)象的密封圈代替O型圈。橡膠O型圈供應(yīng)商</p><p
