O型圈作為往復(fù)式密封，結(jié)構(gòu)緊湊、尺寸小，可以降低元件價(jià)格。主要用在：1）低壓液壓元件中，一般限于短行程和10MPa左右的中等壓力。2）小直徑、短行程以及中等壓力的液壓滑閥中。3）氣動(dòng)滑閥和氣動(dòng)缸中。4）作為組合式往復(fù)動(dòng)密封裝置中的彈性體。O型圈作為往復(fù)動(dòng)密封適合小直徑、短行程、中低壓力的應(yīng)用場(chǎng)合，氣動(dòng)缸、氣動(dòng)滑閥等往復(fù)運(yùn)動(dòng)元件中。在液壓元件中，用O型圈作主要?jiǎng)用芊?，一般限于短行程?0MPa左右的中低壓力。O型圈不適合用作速度非常低的往復(fù)動(dòng)密封和單獨(dú)作為高壓往復(fù)動(dòng)密封。這主要是因?yàn)樵谶@種條件下摩擦較大，會(huì)導(dǎo)致密封過(guò)早失效。在任何型式應(yīng)用中，都要根據(jù)密封件的額定數(shù)據(jù)或能力來(lái)使用，并且要裝配得當(dāng)，才能得到滿意的性能。3、旋轉(zhuǎn)運(yùn)動(dòng)用密封在旋轉(zhuǎn)運(yùn)動(dòng)密封中，通常采用油封和機(jī)械密封。但是油封的使用壓力較低，而且與O型圈相比，顯得過(guò)大和復(fù)雜，工藝性也差。機(jī)械密封雖然可用于高壓（40MPa）、高速（50m/s）及高溫（400℃），但是結(jié)構(gòu)更加復(fù)雜、龐大，而且成本高，只適用于石油、化工等作用的一些重型機(jī)械設(shè)備上。連云港丁晴橡膠O型圈生產(chǎn)公司抗老化O型圈使用壽命長(zhǎng)的進(jìn)口O型密封圈。</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)。

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。

硬度選擇O形圈硬度的選擇是比較重要的。如某電站水泵水輪機(jī)硬度為70（Shore）密封圈，常常剝落，甚至橫向切斷，后采用85～90（Shore）的密封圈，效果理想。硬度低，安裝方便，但容易出現(xiàn)剝落、安裝損傷、擠出甚至壓力。硬度過(guò)高，安裝不方便。通常O形圈硬度40～90IRHD，但在使用中一般70IRHD是比較合適的，對(duì)于硅橡膠是例外，一般使用60IRHD。.O形圈的修整未硫化O形圈膠料在高溫、壓力下為粘稠流體，而到了模壓硫化階段，膠料迅速充滿模腔，其多余的部分(為了防止缺膠，填充在模腔中的膠料，肯定保持一定的過(guò)量)溢出硫化，便形成了溢膠(也稱廢邊、飛邊)。溢邊一旦形成，為使外觀整齊、美觀，必須除去，這一工序習(xí)稱修邊。對(duì)修邊的要求是尺寸精確、外觀整齊。在實(shí)際生產(chǎn)中。產(chǎn)品的修邊往往費(fèi)時(shí)、耗工，對(duì)于要求嚴(yán)的產(chǎn)品，在修邊時(shí)稍有不慎即可能出廢次，必須謹(jǐn)慎對(duì)待。一般來(lái)說(shuō)，產(chǎn)品的尺寸規(guī)格越小、構(gòu)形越復(fù)雜，修邊的難度越高，廢品也越多。河南品牌O型圈生產(chǎn)廠家</p><p
