硬度選擇O形圈硬度的選擇是比較重要的。如某電站水泵水輪機(jī)硬度為70（Shore）密封圈，常常剝落，甚至橫向切斷，后采用85～90（Shore）的密封圈，效果理想。硬度低，安裝方便，但容易出現(xiàn)剝落、安裝損傷、擠出甚至壓力。硬度過高，安裝不方便。通常O形圈硬度40～90IRHD，但在使用中一般70IRHD是比較合適的，對(duì)于硅橡膠是例外，一般使用60IRHD。.O形圈的修整未硫化O形圈膠料在高溫、壓力下為粘稠流體，而到了模壓硫化階段，膠料迅速充滿模腔，其多余的部分(為了防止缺膠，填充在模腔中的膠料，肯定保持一定的過量)溢出硫化，便形成了溢膠(也稱廢邊、飛邊)。溢邊一旦形成，上海氯丁橡膠O型圈廠家現(xiàn)貨，為使外觀整齊、美觀，必須除去，這一工序習(xí)稱修邊。對(duì)修邊的要求是尺寸精確、外觀整齊。在實(shí)際生產(chǎn)中。產(chǎn)品的修邊往往費(fèi)時(shí)、耗工，對(duì)于要求嚴(yán)的產(chǎn)品，在修邊時(shí)稍有不慎即可能出廢次，必須謹(jǐn)慎對(duì)待。一般來(lái)說，產(chǎn)品的尺寸規(guī)格越小、構(gòu)形越復(fù)雜，上海氯丁橡膠O型圈廠家現(xiàn)貨，修邊的難度越高，廢品也越多，上海氯丁橡膠O型圈廠家現(xiàn)貨。進(jìn)口回彈性好的O型圈，請(qǐng)認(rèn)準(zhǔn)蘇州思飛。上海氯丁橡膠O型圈廠家現(xiàn)貨</p><div

O型圈的設(shè)計(jì)與使用O型圈的設(shè)計(jì)、使用不當(dāng)會(huì)加速它的損壞，喪失密封性能。實(shí)驗(yàn)表明，如密封裝置各部分設(shè)計(jì)合理，單純地提高壓力，并不會(huì)造成O型圈的破壞。在高壓、高溫的工作條件下，O型圈破壞的主要原因是O型圈材料的長(zhǎng)久變形和O型圈被擠入密封間隙而引起的間隙咬傷，O型圈在運(yùn)動(dòng)時(shí)出現(xiàn)扭曲現(xiàn)象。長(zhǎng)久變形由于O型圈密封圈用的合成橡膠材料是屬于粘彈性材料，所以初期設(shè)定的壓緊量和回彈堵塞能力經(jīng)長(zhǎng)時(shí)間的使用，會(huì)產(chǎn)生長(zhǎng)久變形而逐漸喪失，隨之發(fā)生泄漏。長(zhǎng)久變形和彈力消失是O型圈失去密封性能的主要原因，以下是造成長(zhǎng)久變形的主要原因。1）壓縮率和拉伸量與長(zhǎng)久變形的關(guān)系2）溫度與O型圈馳張過程的關(guān)系3）介質(zhì)工作壓力與長(zhǎng)久變形。食品級(jí)o型圈-專業(yè)定制各種橡膠密封圈。</p><div

摩擦力與O型圈的應(yīng)用在動(dòng)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(shí)，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(shí)，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(shí)，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(huì)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(yùn)動(dòng)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(huì)引起橡膠的老化，導(dǎo)致O型圈實(shí)效，破壞其密封性能。摩擦還會(huì)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(dòng)往復(fù)運(yùn)動(dòng)用密封時(shí)，摩擦熱還會(huì)引起粘著，造成摩擦力進(jìn)一步增加。運(yùn)動(dòng)用密封在低速運(yùn)動(dòng)時(shí)，摩擦阻力還是引起爬行的一個(gè)因素，影響元件和系統(tǒng)的工作性能。所以對(duì)運(yùn)動(dòng)密封來(lái)說，摩擦性是重要性能之一。摩擦系數(shù)是摩擦特性的一個(gè)評(píng)價(jià)指標(biāo)，合成橡膠摩擦系數(shù)較大，由于密封在運(yùn)動(dòng)狀態(tài)時(shí)。上海氯丁橡膠O型圈廠家現(xiàn)貨</p><p
