對不同種類固定密封或動密封應(yīng)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(jì)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(dāng)場合中，o型圈也常被應(yīng)用，但它受到密封處的速度和壓力的限制。O型密封圈標(biāo)準(zhǔn)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。 </p><p> 摩擦力與O型圈的應(yīng)用在動密封裝置中，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，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，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，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)運動的軸與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，摩擦熱就會引起橡膠的老化，導(dǎo)致O型圈實效，破壞其密封性能。摩擦還會引起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。作氣動往復(fù)運動用密封時，摩擦熱還會引起粘著，造成摩擦力進(jìn)一步增加。運動用密封在低速運動時，摩擦阻力還是引起爬行的一個因素，影響元件和系統(tǒng)的工作性能。所以對運動密封來說，摩擦性是重要性能之一。摩擦系數(shù)是摩擦特性的一個評價指標(biāo)，合成橡膠摩擦系數(shù)較大，由于密封在運動狀態(tài)時。質(zhì)量耐高溫o型圈_新能密封耐高溫o型圈。</p><div

O型圈用于旋轉(zhuǎn)運動存在的主要問題是焦耳熱效應(yīng)。焦耳熱效應(yīng)使高速的旋轉(zhuǎn)軸與O型圈的接觸處產(chǎn)生磨擦熱，生成的熱量使這些接觸部位的溫度不斷上升，橡膠材料受熱嚴(yán)重變形，壓縮量與伸長量發(fā)生變化的現(xiàn)象。發(fā)熱還加速密封材料老化，降低了O型圈的使用壽命；破壞密封油膜，由此引起斷油現(xiàn)象，加速密封的磨損?；谏鲜銮闆r，近年來國內(nèi)外旋轉(zhuǎn)運動用O型圈進(jìn)行了深入的研究。為了避免出現(xiàn)焦耳熱效應(yīng)，關(guān)鍵在于根據(jù)橡膠的性能來正確地選擇設(shè)計O型圈的結(jié)構(gòu)參數(shù)，主要是O型圈的拉伸量和壓縮率。根據(jù)實驗，將旋轉(zhuǎn)運動用O型圈設(shè)計成內(nèi)徑與旋轉(zhuǎn)軸直徑相等或稍大些，一般大3%~5%，在安裝O型圈時，從內(nèi)徑向里壓縮，并將斷面的壓縮量也設(shè)計得小一些，一般約為5%。并且，盡量采用受熱量影響小的密封材料，充分考慮O型圈安裝處的散熱問題。這樣就使O型圈的工作情況大為改善，可應(yīng)用于轉(zhuǎn)速達(dá)4m/s的旋轉(zhuǎn)軸的密封。近年來又出現(xiàn)了耐熱氟橡膠和耐磨聚氨酯橡膠，并且對橡膠元件工作的焦耳熱效應(yīng)有了更深入的了解，并針對此問題研究解決方案，設(shè)計出了新的O型圈密封結(jié)構(gòu)，使O型圈能夠更好的應(yīng)用與高速、高壓的旋轉(zhuǎn)運動。O形密封圈由于其具有體積小。河南加工O型圈規(guī)格</p><p
