O型密封圈O型圈(O-rings)是一種截面為圓形的橡膠密封圈，因其截面為O型，故稱其為O型橡膠密封圈，也叫O型圈。開始出現(xiàn)在19世紀(jì)中葉，當(dāng)時(shí)用它作蒸汽機(jī)汽缸的密封元件。O型圈，是一種圓環(huán)形狀的機(jī)械墊片，它是環(huán)狀的彈性體，斷面為圓形，一般會(huì)固定在一凹槽中，組裝過(guò)程中會(huì)被兩個(gè)或兩個(gè)以上的組件壓縮，因此產(chǎn)生密封的接口。因?yàn)閮r(jià)格便宜，制造簡(jiǎn)單，功能可靠，并且安裝要求簡(jiǎn)單，O型圈是常見(jiàn)的密封用機(jī)械設(shè)計(jì)?？梢猿惺軒资了箍ǎㄇО酰┑膲毫Α型圈可用于靜態(tài)的應(yīng)用中，也可以用在部件之間有相對(duì)運(yùn)動(dòng)的動(dòng)態(tài)應(yīng)用中，例如旋轉(zhuǎn)泵的軸和液壓缸活塞，山東橡膠O型圈廠家。O型密封圈O型圈(O-rings)是一種截面為圓形的橡膠密封圈，山東橡膠O型圈廠家，因其截面為O型，故稱其為O型橡膠密封圈，也叫O型圈。開始出現(xiàn)在19世紀(jì)中葉，當(dāng)時(shí)用它作蒸汽機(jī)汽缸的密封元件，山東橡膠O型圈廠家。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。山東橡膠O型圈廠家</p><div

摩擦力與O型圈的應(yīng)用在動(dòng)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(shí)，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(shí)，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(shí)，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(huì)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(yùn)動(dòng)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(huì)引起橡膠的老化，導(dǎo)致O型圈實(shí)效，破壞其密封性能。摩擦還會(huì)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(dòng)往復(fù)運(yùn)動(dòng)用密封時(shí)，摩擦熱還會(huì)引起粘著，造成摩擦力進(jìn)一步增加。運(yùn)動(dòng)用密封在低速運(yùn)動(dòng)時(shí)，摩擦阻力還是引起爬行的一個(gè)因素，影響元件和系統(tǒng)的工作性能。所以對(duì)運(yùn)動(dòng)密封來(lái)說(shuō)，摩擦性是重要性能之一。摩擦系數(shù)是摩擦特性的一個(gè)評(píng)價(jià)指標(biāo)，合成橡膠摩擦系數(shù)較大，由于密封在運(yùn)動(dòng)狀態(tài)時(shí)。河南安全O型圈批發(fā)全網(wǎng)直銷原裝進(jìn)口NOKG系列O型圈,進(jìn)口氟橡膠圈。</p><div

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(zhǎng)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(guò)大的壓縮率無(wú)疑就會(huì)增大滑動(dòng)摩擦力和長(zhǎng)久形。而壓縮率過(guò)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(guò)大的長(zhǎng)久變形，在高溫工況中尤為嚴(yán)重。 </p><p> 安裝O型圈注意事項(xiàng)（1）安裝前首先進(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,斷面直徑要均勻；（2）安裝前先涂上液壓油或潤(rùn)滑脂；（3）安裝時(shí)要防止扭曲或打折、翹起。同時(shí)要防止器具刮傷。（4）o型圈安裝的斷面直徑壓縮量占（δ1+δ2）為5%一。（5）安裝時(shí)要先考慮o型圈硬度,防止被擠人密封間隙中去,根據(jù)密封間隙和工作壓力來(lái)選擇適當(dāng)?shù)膐形圈的硬度,橡膠硬度應(yīng)隨工作壓力高低與間隙大小而變化,壓力高,間隙大時(shí)硬度應(yīng)稍大,反之則稍小。（6）安裝過(guò)程中防止碰傷,先用銼修平銳利毛刺或倒成過(guò)度倒角,在其通過(guò)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形圈的作用。（7）0形圈在安裝前保存期間,要防止與酸性和堿性物質(zhì)接觸,以免變形而致密封效果不好。食品級(jí)o型圈-蘇州思飛專業(yè)生產(chǎn)密封件-大量現(xiàn)貨。</p><div

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(guò)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(jì)時(shí)應(yīng)注意以下幾點(diǎn)：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(gè)方面來(lái)考慮。2）O型圈斷面尺寸應(yīng)均勻，并且在每次安裝時(shí)都應(yīng)在密封部位充分涂抹潤(rùn)滑油或潤(rùn)滑脂。有時(shí)也可以采用浸透潤(rùn)滑油的氈圈式加油裝置。3）加大O型圈的截面直徑，動(dòng)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(shí)，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。進(jìn)口O型圈|進(jìn)口O形圈|現(xiàn)貨供應(yīng)英制O型圈規(guī)格尺寸表。山東橡膠O型圈廠家</p><p
