壓縮率壓縮率W通常用下式表示:W=(d0-h)/d0d0:O型圈在自由狀態(tài)下的截面直徑(mm);h:O型圈槽底與被密封表面的距離(溝槽深度)，即O型圈壓縮后的截面高度(mm)在選取O形圈的壓縮率時,應從如下3方面考慮:1.要有足夠的密封接觸面積;2.摩擦力盡量小;3.盡量避免長久變形，天津品牌O型圈訂做。從以上這些因素不難發(fā)現(xiàn),他們相互之間存在矛盾。壓縮率大就可獲得大的接觸壓力，但是過大的壓縮率無疑就會增大滑動摩擦力和長久形。而壓縮率過小則可能由于密封溝槽的同軸度誤差和O形圈誤差不符合要求，消失部分壓縮量而引起泄漏。因此，在選擇O形圈的壓縮率時，要權衡各方面的因素。一般靜密封壓縮率大于動密封，但其極值應小于25%，否則壓縮應力明顯松弛，天津品牌O型圈訂做，天津品牌O型圈訂做，將產(chǎn)生過大的長久變形，在高溫工況中尤為嚴重。耐高溫o型圈_專業(yè)生產(chǎn)廠家。天津品牌O型圈訂做</p><div

氟橡膠O型圈簡介FPM(FluoroCarbonRubber)分子內(nèi)含氟之橡膠，依氟含量(即單體構造)而有各種類型。目前廣用的六氟化系氟橡膠早由杜邦公司以”Viton”商品名上市。耐高溫性優(yōu)于硅橡膠，有較好的耐化學性、耐大部分油及溶劑(酮、酯類除外)、耐候性及耐臭氧性；耐寒性則較不良，一般使用溫度范圍為-20~250℃。特殊配方可耐低溫至-40℃。優(yōu)點：·可抗熱至250℃·對于大部份油品及溶劑都具有抵抗的能力，尤其是所有的酸類、脂族烴、芳香烴及動植物油缺點：·不建議使用于酮類，低分子量的酯類及含硝的混合物?！て?、機車、柴油發(fā)動機及燃料系統(tǒng)。適用范圍:·化工廠的密封件。(FFKM)O型圈全氟醚橡膠是由TFE（主鏈）、PMVE（支鏈）及架橋部所構成，它不*具有像PTFE一樣優(yōu)異耐高溫，耐化學腐蝕的性能（可耐1600余種化學品的腐蝕），還兼?zhèn)淞讼鹉z的彈性，其在300℃時的壓縮變形率也*在50%以下。普通全氟橡膠工作溫度范圍為-25℃~+240℃間，Kalrez7075耐高溫可達327℃，即使當暴露在316℃的恒溫中或像343℃這樣的間歇高溫環(huán)境中，Kalrez制作也不會發(fā)生導致密封失效的硬化和脆化，Kalrez在與侵蝕性流體的浸漬直接接觸中依然能保持其彈力和回彈性能。事實上。天津品牌O型圈訂做O型圈廠家，請認準-蘇州思飛。</p><div

O形密封圈適用于裝在各種機械設備上，在規(guī)定的溫度、壓力、以及不同的液體和氣體介質(zhì)中，于靜止或運動狀態(tài)下起密封作用。O型圈也有其優(yōu)勢：--適合多種密封形式：靜態(tài)密封、動態(tài)密封適合各種用途材料，尺寸和溝槽都已標準化，互換性強--適合多種運動方式：旋轉(zhuǎn)運動、軸向往復運動或組合運動（例如旋轉(zhuǎn)往復組合運動）--適合多種不同的密封介質(zhì)：油、水、氣、化學介質(zhì)或其它混合介質(zhì)通過選用合適的橡膠材料和適當?shù)呐浞皆O計，實現(xiàn)對油、水、空氣、煤氣及各種化學介質(zhì)有效的密封作用。溫度使用范圍廣（－60℃～+220℃），固定使用時壓力可達1500Kg/cm2(與補強環(huán)并用)。--設計簡單，結構小巧，裝拆方便O形圈斷面結構極其簡單，且有自密封作用，密封性能可靠由于O形圈本身及安裝部位結構都極其簡單，且已形成標準化，因此安裝更換都非常容易。

硅膠O型圈有很好的電絕緣性能?？估姸容^一般橡膠差且不具耐油性，硅膠的耐溫范圍溫：-43~210℃，突出的優(yōu)點是擁有優(yōu)良的耐高溫、抗靜電性能，而且通過特殊配方工藝，可以生產(chǎn)成食品級材質(zhì)優(yōu)點：1、調(diào)制配方后抗張強度可達到500PSI及抗斯性可達88LBS。2、良好及具良好的壓縮變形。3、對中性溶劑具有良好的抵抗性。4、具較好的抗熱性。5、具較好的抗寒性。6、對于臭氧及氧化物的侵蝕具較好的抵抗力。缺點：1、不建議使用于大部分厚縮的溶劑、油品、厚縮酸及經(jīng)稀釋后的氫氧化鈉之中。2、電子行業(yè)的密封件或橡膠零件，如手機按鍵、DVD內(nèi)的減震墊、電纜線接慶內(nèi)的密封件等。硅橡膠O型圈應用它既可以耐高溫也可以耐低溫，同時在密封性上和介電性上都有很好的特性，因此硅橡膠O型圈常用語制作各種密封件、高壓電線電纜、高低溫硅橡膠制品的膠管等，同時因為硅橡膠O型圈具備了硅橡膠制品的無毒無色無味的特性，因此也可以用于食品以及醫(yī)療行業(yè)。缺點硅橡膠O型圈的價格相對于其他硅橡膠制品比較昂貴，同時在耐腐蝕性上也不如其他的硅橡膠制品，在耐酸耐堿耐化學溶劑上面稍顯不足，在機械拉伸方面強度也比較低。質(zhì)量原裝耐油O型圈-蘇州思飛。</p><div

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，為使外觀整齊、美觀，必須除去，這一工序習稱修邊。對修邊的要求是尺寸精確、外觀整齊。在實際生產(chǎn)中。產(chǎn)品的修邊往往費時、耗工，對于要求嚴的產(chǎn)品，在修邊時稍有不慎即可能出廢次，必須謹慎對待。一般來說，產(chǎn)品的尺寸規(guī)格越小、構形越復雜，修邊的難度越高，廢品也越多。全網(wǎng)直銷原裝進口NOKG系列O型圈,進口氟橡膠圈。天津品牌O型圈訂做</p><p
