style="text-indent:25px">O型圈結(jié)構(gòu)設(shè)計一、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，往往只用一個密封件便能完成密封效果。 3、密封性能好，用作固定密封時幾乎沒有泄漏，用作運動密封時，只在速度較高時才有些泄漏。 4、運動摩擦阻力很小，對于壓力交變的場合也能適應。 5、尺寸和溝槽已標準化，成本低，產(chǎn)品易得，便于使用和外購。與其它密封圈相比，O形圈也存在問題：起動時的摩擦阻力大。用作氣動裝置的密封時，必須加潤滑油，防止磨損。對偶合配件，如運動面、溝槽、間隙等的加工尺寸及精度要求很嚴。</p><p style="text-indent:25px">O形圈橡膠材料的硬度與工作壓力的關(guān)系在橡膠材料標準中，以硬度和壓縮長久變形兩項性能較為主重。選擇壓縮變形較小的橡膠材料對密封性能是有利的，而硬度對于O形橡膠密封圈耐壓和抗擠又是至關(guān)重要的。根據(jù)國內(nèi)標準和實踐經(jīng)驗，橡膠在規(guī)定溫度下的壓縮長久變形較大不超過50%。而橡膠的硬度與密封工作壓力密切相關(guān)，壓力越高，硬度也是越高; 橡膠O型圈模壓制品在硫化時，膠料會很快充滿整個模腔，因為填充的膠料需要一定的過盈量，這些多余的膠料就會沿著分模面流出，造成內(nèi)外徑不同厚度的膠邊。由于橡膠O型圈是需要嚴格控制質(zhì)量和外觀的，因為其功能為密封，小小的膠邊就有可能影響到整個密封性能，所以硫化后的成品還需要進行修邊加工，要對這些多余的膠邊進行去除工作，這個過程就叫做修邊。但是一般來說尺寸規(guī)格越小，構(gòu)型越復雜，難度越高，費時耗工越多。橡膠密封件運動方向，先決定密封件所在位置的運動方向，例如往復、旋轉(zhuǎn)、螺旋或固定。</p><div

雖然損耗因子較小，但其綜合性能較好，具有優(yōu)異的彈性，耐疲勞性好，生熱低，蠕變小，與金屬件黏合性能好，耐寒性、電絕緣性和加工性能也好，因此NR被普遍地用作減震目的，要求耐低溫或耐天候性能時，可與BR或CR并用或共混改性。Nishiue等采用NR、BR及碳原子數(shù)大于4的含有-OH基團有機酸的金屬鹽制成的減震器具有較好的耐久性能，在70℃×22h和40℃×148h條件下的壓縮長久變形分別為17.0%和11.7%。橡膠密封件耐電暈性，耐電弧性、耐高低溫、耐老化性能好、耐高溫性能；北京復合橡膠密封件批發(fā)廠家</p><p style="text-indent:25px">橡膠密封件可置**溫下加熱，不變形，不產(chǎn)生有害物質(zhì)。山東耐寒橡膠密封件誠信廠家</p><p style="text-indent:25px">因為不同的設(shè)備的作業(yè)環(huán)境不同，所需要的橡膠密封件的耐溫、耐油的條件也不同，而且每種產(chǎn)品因為形狀各異，因此在選擇密封件時需要另外設(shè)計。橡膠密封件的密封材料的性能是保證有效密封的重要因素，選擇密封材料，主要是根據(jù)密封元件的工作環(huán)境，如使用溫度、工作壓力、所使用的工作介質(zhì)以及運動方式等。密封材料的基本要求如下： 1、具有一定的力學性能，如拉伸強度、伸長率等。 2、彈性和硬度適當，壓縮長久變形小。 3、耐高溫和低溫，高溫下不分解、軟化，低溫下不硬化。 4、與工作介質(zhì)相適應，不產(chǎn)生溶脹、分解、硬化等。 5、耐氧性和耐老化性好，經(jīng)久耐用。 6、耐磨損，不腐蝕金屬。 7易于成形加工，價格低廉。山東耐寒橡膠密封件誠信廠家</p><p>
