O型密封圈還能用做軸向往復(fù)運(yùn)動和低速旋轉(zhuǎn)運(yùn)動的動態(tài)密封元件，安徽阻燃橡膠密封件專業(yè)廠家.根據(jù)不同的條件,可分別選擇不同的材料與之相適應(yīng). O型密封圈通常選用時要盡量選用大截面的O型圈.在相同間隙的情況下. O型密封圈被擠入間隙的體積應(yīng)當(dāng)小于其被擠入的較大允許值。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，安徽阻燃橡膠密封件專業(yè)廠家，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，安徽阻燃橡膠密封件專業(yè)廠家，但它受到密封處的速度和壓力的限制。橡膠密封件，要在伸張狀態(tài)下裝進(jìn)溝槽，裝配后要受到大的彈性變形。安徽阻燃橡膠密封件專業(yè)廠家</p><div

1.按原材料來源與方法：橡膠可分為天然橡膠和合成橡膠兩大類。其中天然橡膠的消耗量占1/3，合成橡膠的消耗量占2/3。 2.按橡膠的外觀形態(tài)：橡膠可分為固態(tài)橡膠(又稱干膠)、乳狀橡膠(簡稱乳膠)、液體橡膠和粉末橡膠四大類。 3.根據(jù)橡膠的性能和用途：除天然橡膠外，合成橡膠可分為通用合成橡膠、半通用合成橡膠、**合成橡膠和特種合成橡膠。 4.根據(jù)橡膠的物理形態(tài)：橡膠可分為硬膠和軟膠，生膠和混煉膠等。根據(jù)橡膠種類及交聯(lián)形式，在工業(yè)使用上，橡膠又可按如下分類。一類按耐熱及耐油等功能分為:普通橡膠、耐熱橡膠、耐油橡膠以及耐天候老化橡膠、耐特種化學(xué)介質(zhì)橡膠等橡膠O型圈密封性能優(yōu)良，工作壽命高，動態(tài)壓力密封工作壽命比常規(guī)橡膠密封制品高5-10倍，較高可達(dá)數(shù)十倍，在某些條件下可與密封基體同壽命。青海品質(zhì)橡膠密封件制造廠家橡膠密封件的作用是封閉箱室油液外溢的縫隙，并防止灰塵、沙土等污物侵入箱室內(nèi)部。</p><div

style="text-indent:25px">橡膠密封O形圈儲存條件及存放年限溫度：5-25℃是比較理想的儲存溫度。應(yīng)避免接觸熱源及陽光照射。從低溫儲藏狀態(tài)取出的密封件，應(yīng)先將其置于 20℃的環(huán)境中，然后再使用。濕度：倉庫的相對濕度應(yīng)下小于 70%，避免過于潮濕或過于干燥，不可出現(xiàn)冷凝現(xiàn)象。光照：要避免太陽光及強(qiáng)的含有紫外線人工光源。防紫外線的包裝袋可提供較佳的保護(hù)。建議倉庫的窗戶上涂上紅色或橙色涂料或貼薄膜。輻射：避免電離輻射對密封件的損傷。氧和臭氧：橡膠材料應(yīng)避免暴露在循環(huán)流動的空氣中?？赏ㄟ^包裝、纏繞、存放在氣密容器中或其他合適方法實(shí)現(xiàn)此目的。臭氧對大部分彈性體有害，倉庫內(nèi)避免有下面這些設(shè)備：**蒸氣燈、高壓電器設(shè)備、電動機(jī)等設(shè)備。變形：橡膠件應(yīng)盡可能以自由狀態(tài)放置，避免受拉伸、壓縮或其他變形。與液體或半固體材料的接觸：不得接觸溶劑、油、脂或其它半固體材料。與金屬或非金屬材料的接觸：不允許接觸磁性材料、鑄鐵、銅及其合金，或含有會損壞橡膠的材料。不可用 PVC材料來包裝密封件。不同材料的密封件不可混裝。硅橡膠O型圈既可以耐高溫也可以耐低溫。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="安徽阻燃橡膠密封件專業(yè)廠家,橡膠密封件"

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，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、高雅電線電纜、高低溫硅橡膠制品的膠管等，同時因?yàn)楣柘鹉zO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(diǎn)：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(xué)溶劑上面稍顯不足，在機(jī)械拉伸方面強(qiáng)度也比較低。橡膠密封件密封性能好，防水不漏，環(huán)保無毒。江蘇高效橡膠密封件專業(yè)廠家</p><p

O型圈在多種液壓、氣動件管接頭、圓筒面及法蘭面等結(jié)合處被普遍使用。對于在運(yùn)動過程中使用的O型圈，當(dāng)工作壓力大于9.8Mpa時，如單向受壓，就在O型圈受壓力方向的另一側(cè)設(shè)置一個擋圈；如雙向受壓，則在O型圈兩側(cè)各放一個擋圈。為了減小摩擦力，也可采用楔型擋圈。當(dāng)壓力液體從左方施加作用時，右方擋圈被推起，左方擋圈不與被密封表面接觸，因此摩擦力減小?？偟膩碚f，采用擋圈會增大密封裝置的摩擦力，而楔型擋圈對減小這種摩擦力具有十分重要的意義。對于固定用的O型圈，當(dāng)工作壓力大于32Mpa時，也需要使用擋圈。安徽阻燃橡膠密封件專業(yè)廠家</p><p>
