O型圈材料的壓縮長久變形率與溫度有關(guān)。當變形率在40%或更大時，即會出現(xiàn)泄漏，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℃。因此各國對O型圈的長久變形作了規(guī)定。中國標準橡膠材料的O型圈在不同溫度下的尺寸變化見表。同一材料的O型圈，在同一溫度下，截面直徑大的O型圈壓縮長久變形率較低。在油中的情況就不同了。由于此時O型圈不與氧氣接觸，般發(fā)生在動密封狀態(tài)。O型圈如果裝配的妥善，并且使用條件適當，湖北專業(yè)O型圈訂做，一般不大容易在往復運動狀態(tài)下產(chǎn)生滾動或扭曲，因為O型圈與溝槽的接觸面積大于在滑動表面上的摩擦接觸面積，湖北專業(yè)O型圈訂做，而且O型圈本身的抗拒能力原來就能阻止扭曲，湖北專業(yè)O型圈訂做。摩擦力的分布也趨向保持O型圈在其溝槽中靜止不動，因為靜摩擦大于滑動摩擦，而且溝槽表面的粗糙度一般不如滑動表面的粗糙度。

對不同種類固定密封或動密封應用場合，o型密封圈為設(shè)計者提供了一種既有效又經(jīng)濟的密封元件。o型圈是一種雙向作用密封元件。安裝時徑向或軸向方面的初始壓縮，賦予o型圈自身的初始密封能力。由系統(tǒng)壓力而產(chǎn)生的密封力與初始密封力合成總的密封力，它隨系統(tǒng)壓力的提高而提高。o型圈在靜密封場合，顯示了突出的作用。然而，在動態(tài)的適當場合中，o型圈也常被應用，但它受到密封處的速度和壓力的限制。O型密封圈標準O型密封圈是一種擠壓型密封，擠壓型密封的基本工作原理是依靠密封件發(fā)生彈性變形，在密封接觸面上造成接觸壓力，接觸壓力大于被密封介質(zhì)的內(nèi)壓，則不發(fā)生泄漏，反之則發(fā)生泄漏。在用于靜密封和動密封時，密封接觸面接觸壓力產(chǎn)生原因和計算方法不盡相同，需分別說明。湖北專業(yè)O型圈訂做</p><p
