style="text-indent:25px">O型橡膠圈是一種截面為圓形的橡膠圈，因其截面為O型，故稱(chēng)其為O型橡膠圈。是液壓與氣壓傳動(dòng)系統(tǒng)中使用較普遍的一種。 O型橡膠圈是具有圓形截面的環(huán)行橡膠橡膠圈，主要用于機(jī)械部件在靜態(tài)條件下防止液體和氣體介質(zhì)的泄露。在某些情況下，它還能用作軸向往復(fù)運(yùn)動(dòng)和低速旋轉(zhuǎn)運(yùn)動(dòng)的動(dòng)態(tài)密封元件。根據(jù)不同的條件，可分別選擇不同的材料與之相適應(yīng).。對(duì)不同種類(lèi)固定密封或動(dòng)密封應(yīng)用場(chǎng)合，O型橡膠圈為設(shè)計(jì)者提供了一種既有效又經(jīng)濟(jì)的密封元件。O 形圈是安裝在溝槽中、適量壓縮的 O 形截面的密封環(huán)。在各種動(dòng)密封或靜密封的應(yīng)用中，O形圈是一種有效且經(jīng)濟(jì)的密封元件。浙江直銷(xiāo)橡膠密封件直銷(xiāo)廠家橡膠O型圈成品的脹大于縮短率動(dòng)搖規(guī)模很大。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">O型圈的修邊分為手工、機(jī)械和冷凍等三類(lèi): 1。手工修邊。操作者手持刀具，沿著產(chǎn)品的外緣，將溢邊逐步修去。這是較原始的方法。效率低、質(zhì)量難保證，特別對(duì)尺寸較小,精度要求高的O型圈難以做到徹底、于凈，而且很容易損及產(chǎn)品本體與溢邊的連接部。往往留下齒痕、缺口，從而留下漏油、漏氣等影響密封的后遺問(wèn)題。另外。手工修邊對(duì)操作熟練程度的依賴也很突出。 2.機(jī)械修邊。為了提高效率和質(zhì)量，出現(xiàn)了機(jī)械修邊。常見(jiàn)的是帶旋轉(zhuǎn)刀刃的**電動(dòng)修邊機(jī)。所用的刀刃需與制品尺寸高度匹配。如果產(chǎn)品的內(nèi)外緣都有溢邊。則可設(shè)計(jì)成雙刃、多刃口。以實(shí)現(xiàn)一次完成。機(jī)械修邊的加工精度超過(guò)手工修邊，效率也有成倍提高，特別對(duì)一模多腔的產(chǎn)品而言，可以按照產(chǎn)品的排列與分布，設(shè)計(jì)出與之匹配的刀具。待產(chǎn)品出模后?？烧嫣咨希淮瓮瓿蓻_切。在加熱的配合下，一次能修幾十個(gè)。關(guān)鍵是沖切溫度必須掌握好，防止過(guò)高后粘連。</p><p style="text-indent:25px">硬度選擇橡膠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(guò)高，安裝不方便。通常橡膠O形圈硬度40~90 IRHD，但在使用中一般70 IRHD是比較合適的，對(duì)于硅橡膠是例外，一般使用60 IRHD。硅橡膠材質(zhì) 硅橡膠O型圈是以硅橡膠為材質(zhì)的環(huán)形產(chǎn)品，它是硅橡膠制品中的一款分類(lèi)，硅橡膠O型圈具有溫度適應(yīng)廣、密封性、絕緣性、介電性、環(huán)保性等良好的特性，一般的硅橡膠O型圈的主要構(gòu)成材料是VMQ-甲基乙烯基硅橡膠。應(yīng)用：它既可以耐高溫也可以耐低溫，同時(shí)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(yǔ)制作各種密封件、高雅電線電纜、高低溫硅橡膠制品的膠管等，同時(shí)因?yàn)楣柘鹉zO型圈具備了硅橡膠制品的無(wú)毒無(wú)色無(wú)味的特性，因此也可以用于食品以及醫(yī)療行業(yè)。缺點(diǎn)：硅橡膠O型圈的價(jià)格相對(duì)于其他硅橡膠制品比較昂貴，同時(shí)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(xué)溶劑上面稍顯不足，在機(jī)械拉伸方面強(qiáng)度也比較低。橡膠O型密封圈材料品種多。</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(jì)、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(shí)，首先應(yīng)盡量選用新國(guó)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(gè)指標(biāo)的是它的硬度，一般采用邵氏硬度來(lái)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(chǎng)上常見(jiàn)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。在實(shí)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。重慶定制橡膠密封件價(jià)格</p><p
