style="text-indent:25px">橡膠密封圈的經(jīng)密封：可以分為三種情況；往復(fù)運(yùn)動(dòng)一般取W=10%～15%。旋轉(zhuǎn)運(yùn)動(dòng)密封在選取壓縮率時(shí)必須要考慮焦耳熱效應(yīng)，一般來說，旋轉(zhuǎn)運(yùn)動(dòng)用O形圈的內(nèi)徑要比軸徑大3%-5%，外徑的壓縮率W=3%-8%。低摩擦運(yùn)動(dòng)用O型圈，為了減少摩擦阻力，一般均選取較小的壓縮率，即W=5%-8%，此外，還要考慮到介質(zhì)和溫度引起的橡膠材料膨脹。通常在給定的壓縮變形之外，允許的較大膨脹率為15%，超過這一范圍說明材料選用不合適，應(yīng)改用其他材料的O形圈，或?qū)o定的壓縮變形率予以修正。橡膠O型圈在裝入密封溝槽后，一般都有一定的拉伸量。與壓縮率一樣，拉伸量的大小對(duì)O型圈的密封性能和和使用壽命也有很大的影響。拉伸量大不但會(huì)導(dǎo)致O型圈安裝困難，同時(shí)也會(huì)因截面直徑d0發(fā)生變化而使壓縮率降低，以致引起泄漏。四川硅橡膠密封件橡膠O型密封圈適用于裝在各種機(jī)械設(shè)備上。</p><div

一、O形橡膠密封圈是一種斷面形狀為圓形的密封元件，它普遍用于多種機(jī)械設(shè)備中，在一定溫度、壓力及不同的液體或氣體介質(zhì)中起到密封作用。與其它密封圈相比，具有如下的優(yōu)越性能： 1、密封部位結(jié)構(gòu)簡(jiǎn)單，安裝部位緊湊，而且重量較輕。 2、有自密封作用，往往只用一個(gè)密封件便能完成密封效果。 3、密封性能好，用作固定密封時(shí)幾乎沒有泄漏，用作運(yùn)動(dòng)密封時(shí)，只在速度較高時(shí)才有些泄漏。 4、運(yùn)動(dòng)摩擦阻力很小，對(duì)于壓力交變的場(chǎng)合也能適應(yīng)。
