style="text-indent:25px">橡膠密封圈的經(jīng)密封：可以分為三種情況；往復(fù)運(yùn)動一般取W=10%～15%。旋轉(zhuǎn)運(yùn)動密封在選取壓縮率時必須要考慮焦耳熱效應(yīng)，一般來說，旋轉(zhuǎn)運(yùn)動用O形圈的內(nèi)徑要比軸徑大3%-5%，外徑的壓縮率W=3%-8%。低摩擦運(yùn)動用O型圈，為了減少摩擦阻力，一般均選取較小的壓縮率，即W=5%-8%，此外，還要考慮到介質(zhì)和溫度引起的橡膠材料膨脹。通常在給定的壓縮變形之外，允許的較大膨脹率為15%，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，或?qū)o定的壓縮變形率予以修正。橡膠O型圈在裝入密封溝槽后，福建耐酸堿橡膠密封件專業(yè)廠家，一般都有一定的拉伸量。與壓縮率一樣，拉伸量的大小對O型圈的密封性能和和使用壽命也有很大的影響，福建耐酸堿橡膠密封件專業(yè)廠家，福建耐酸堿橡膠密封件專業(yè)廠家。拉伸量大不但會導(dǎo)致O型圈安裝困難，同時也會因截面直徑d0發(fā)生變化而使壓縮率降低，以致引起泄漏。硅橡膠O型圈既可以耐高溫也可以耐低溫。福建耐酸堿橡膠密封件專業(yè)廠家</p><div

style="text-indent:25px">型圈是密封中較常用的一種密封件。但由于選用、溝槽設(shè)計、加工和裝配上的不當(dāng)，常常造成漏油故障，可謂是小件壞大事。選用O型圈時，首先應(yīng)盡量選用新國標(biāo)，線徑2.65和3.55的使用較為普遍，在外徑大于30左右，結(jié)構(gòu)尺寸允許的情況下，盡量選用線徑3.55的O型圈，以達(dá)到更大的壓縮量和接觸面積。圈的材料主要有丁氰橡膠NBR和氟橡膠FKM，氟橡膠更適用于高溫工況。除材料之外，O型圈很重要的一個指標(biāo)的是它的硬度，一般采用邵氏硬度來表示，從60到90左右不等，數(shù)值越大表示硬度越高。在同樣壓力下，硬度越高，防擠出（變形甚至撕裂）的能力就越強(qiáng)。因此，應(yīng)選用硬度較高的O型圈。但是，市場上常見的O型圈均為丁氰橡膠制成，邵氏硬度一般在70左右，難以滿足相當(dāng)一部分工況的要求。福建耐酸堿橡膠密封件專業(yè)廠家在實際的需要用到橡膠密封件的產(chǎn)品生產(chǎn)中，正確的選擇橡膠密封件是很重要的。</p><div

style="text-indent:25px">橡膠O型圈壓縮率W的選擇應(yīng)考慮使用條件，靜密封或動密封；靜密封又可分為徑向密封與軸向密封；徑向密封（或稱圓柱靜密封）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。軸向密封根據(jù)壓力介質(zhì)作用于O形圈的內(nèi)徑還是外徑又分受內(nèi)壓和受外壓兩種情況，內(nèi)壓增加的拉伸，外壓降低O形圈的初始拉伸。上述不同形式的靜密封，密封介質(zhì)對O形圈的作用方向是不同的，所以預(yù)壓力設(shè)計也不同。對于動密封則要區(qū)分是往復(fù)運(yùn)動密封還是旋轉(zhuǎn)運(yùn)動密封。靜密封：圓柱靜密封裝置和往復(fù)運(yùn)動式密封裝置一樣，一般取W=10%～15%；平面靜密封裝置取W=15%～30%。</p><p style="text-indent:25px">橡膠O型密封圈與其他型式密封圈比較，具有以下優(yōu)點: 1、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(biāo)準(zhǔn)化，互換性強(qiáng) 2、適合多種運(yùn)動方式:旋轉(zhuǎn)運(yùn)動、軸向往復(fù)運(yùn)動或組合運(yùn)動(例如旋轉(zhuǎn)往復(fù)組合運(yùn)動) 3、適合多種不同的密封介質(zhì):油、水、氣、化學(xué)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(dāng)?shù)呐浞皆O(shè)計，實現(xiàn)對油、水、空氣、煤氣及各種化學(xué)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(dá) 1500Kg/cm2( 與補(bǔ)強(qiáng)環(huán)并用 )。 4、設(shè)計簡單，結(jié)構(gòu)小巧，裝拆方便橡膠O形圈斷面結(jié)構(gòu)極其簡單，且有自密封作用，密封性能可靠。由于橡膠O 形圈本身及安裝部位結(jié)構(gòu)都極其簡單，且已形成標(biāo)準(zhǔn)化，因此安裝更換都非常容易。 5、材料品種多可以根據(jù)不同的流體進(jìn)行選擇:有丁腈橡膠(NBR)、氟橡膠(FKM)、硅橡膠(SIL)、三元乙丙橡膠(EPDM)、氯丁橡膠(CR)、天然橡膠(NR) 氫化丁腈膠 (HNBR) 、丁基橡膠(IIR)、硅氟橡膠 (FLS)等O形圈是一種有效且經(jīng)濟(jì)的密封元件。</p><div style="width:100%;text-align:

style="text-indent:25px">在實際的需要用到橡膠密封件的產(chǎn)品生產(chǎn)中，正確的選擇橡膠密封件是很重要的， 1.運(yùn)動方向：先決定密封件所在位置的運(yùn)動方向，例如往復(fù)、旋轉(zhuǎn)、螺旋或固定。 2.密封重點：例如決定活動點是在內(nèi)徑的拉桿封或活動點是在外徑的活塞封等。 3.溫度等級：從原廠機(jī)械使用說明查閱或按實際工作環(huán)境評估工作溫度，決定所需使用材料。 4.壓力等級：從原廠機(jī)械使用說明查閱有關(guān)數(shù)據(jù)，或通過觀察原橡膠密封件的軟硬度和結(jié)構(gòu)推斷工作壓力等級。 5.尺寸大?。憾鄶?shù)用戶都會按使用過的舊樣品選購，但密封件在使用一段時間后，會被溫度、壓力及磨損等因素大幅影響其原來的尺寸，按樣選擇只能作為一個參考，更好的方法是量度密封件所在位置的金屬槽尺寸，準(zhǔn)確性會較高。橡膠密封件對機(jī)械設(shè)備整體的性能、使用壽命等都有著重大的影響。浙江非標(biāo)橡膠密封件價格</p><p
