style="text-indent:25px">要保證合理的密封性能，動密封和靜密封都要有合適的表面粗糙度。一般靜密封Ra6.3μm~Ra3.2μm，動密封Ra3.2μm~Ra1.6μm。但不是粗糙度越高越好，如果安裝面的粗糙度太高，平直度差，有的會出現(xiàn)凸棱。一方面O型環(huán)被壓縮后，有的面因密封不嚴(yán)而漏油。另一方面O型環(huán)在溝槽中會隨著壓力高的方向向壓力低的方向滑動，造成O型環(huán)損傷，引起泄漏。橡膠O型圈的拉伸率過大，會引起應(yīng)力松弛，造成O型圈的內(nèi)徑增大。造成與軸面形成接觸間隙，安裝過程中會因?yàn)檎駝佣蛊涿撀?。同時，橡膠O型圈由于擠壓力度不均勻，影響O型圈的使用壽命。</p><p style="text-indent:25px">橡膠O形圈運(yùn)用不當(dāng)會加快損壞其密封功能：滑動外表的原料對O形圈的壽數(shù)也有影響。滑動外表原料的硬度越大、耐磨性越高、堅(jiān)持光亮的才能就越強(qiáng)，O形圈的壽數(shù)也就越長。這也是液壓缸活塞桿外表鍍鉻的重要緣由。同理能夠解說具有相同粗糙度的用銅、鋁合金制成的滑動外表比鋼制滑動外表對密封圈的矛盾與磨損更為嚴(yán)峻，低硬度、大緊縮量的密封圈不如高硬度、小緊縮量的密封圈經(jīng)用的狀況。矛盾力與O形圈的使用。在動密封設(shè)備中，矛盾與磨損是O形圈損壞的重要影響要素。磨損程度首要取決于矛盾力的巨細(xì)。當(dāng)液體壓力細(xì)小時，O形圈矛盾力的巨細(xì)取決于它的預(yù)緊縮量。當(dāng)作業(yè)液體接受壓力時，矛盾力隨之作業(yè)壓力的添加而增大。在作業(yè)壓力小于20MPa的狀況下，近似地呈線形聯(lián)系。壓力大于20MPa時，跟著壓力的添加，O形圈與金屬外表觸摸面積的添加也逐步緩慢，矛盾力的添加也相應(yīng)緩慢。在正常狀況下，O形圈的運(yùn)用壽數(shù)跟著液體壓力的升高將會近似的呈平方聯(lián)系而減小。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。</p><div

style="text-indent:25px">橡膠O形圈資料的緊縮持久變形率與溫度有關(guān)。當(dāng)變形率在40%或更大時，即會呈現(xiàn)走漏，所以幾種膠料的耐熱性界限為：丁腈橡膠70℃，三元乙丙橡膠100℃，氟橡膠140℃。因而各國對O形圈的持久變形作了規(guī)則。中國標(biāo)準(zhǔn)橡膠資料的O形圈在不一樣溫度下的尺度改變見表。同一資料的O形圈，在同一溫度下，截面直徑大的O形圈緊縮持久變形率較低。在油中的狀況就不一樣了。因?yàn)榇丝蘋形圈不與氧氣觸摸，所以上述不良反應(yīng)大為削減。加之又通常會致使膠料有必定的脹大，所以因溫度致使的緊縮持久變形率將被抵消。因而，在油中的耐熱性大為進(jìn)步。以丁腈橡膠為例，它的作業(yè)溫度可達(dá)120℃或更高。徑向密封的泄漏間隙是徑向間隙，軸向密封（或稱平面靜密封）的泄漏間隙是軸向間隙。吉林復(fù)合橡膠O型圈生產(chǎn)廠家</p><p
