內(nèi)密封和外密封 </p> <p> **通常的做法是將密封安裝在填料盒的內(nèi)部。但這種做法要求在密封維修時將液泵的濕端拆卸下來，其主要好處是密封的環(huán)境衛(wèi)生易于控制。 </p> <p> <span style="font-size:12px;"> 外密封的安裝方式是將靜態(tài)密封面的方向顛倒過來，主軸上的旋轉(zhuǎn)單元位于填料盒壓蓋的外面。外密封主要具有以下五大好處：</span> </p> <p> 安裝容易; </p> <p> 費用相對較低; </p> <p> 可以連續(xù)監(jiān)控和清潔; </p> <p> 適于無法在內(nèi)部安裝密封的很小填料盒; </p> <p> 由于其位置接近軸承，對主軸偏差的困難影響較少。 </p> <p> <span style="font-size:12px;"> 其主要缺點是離心力會將固體顆粒從密封的下面甩向密封的接觸面上。因此，這類密封主要適用于清潔且不含有磨料的液體。</span> </p> <p> <span style="font-size:12px;"> 近年來，分離式密封已成為外密封中的另一重要附加特性。分離式密封是一個成套總成，安裝于填料盒與軸承套之間，采用這種設(shè)計，在密封需要更換時，不需要每次都拆卸液泵。這類密封結(jié)合探討其他設(shè)計標(biāo)準(zhǔn)正在逐步開發(fā)之中。由于這種設(shè)計易于更換密封，因此應(yīng)抵擋**只更換密封件的這種誘惑，而對出現(xiàn)故障的根源不做進(jìn)一步的調(diào)查，這一點非常重要。</span>

隨著時代的高速發(fā)展，對石油資源的需求量不斷增加，石油煉廠的生產(chǎn)任務(wù)越來越重。泵用機(jī)械在石油煉廠生產(chǎn)過程中發(fā)揮著非常重要的作用，但在其實際運行過程中，其機(jī)械密封往往會出現(xiàn)各種問題，不*影響機(jī)械的正常使用，還容易導(dǎo)致安全問題的發(fā)生。文章對石油煉廠常用機(jī)械密封的設(shè)計改進(jìn)與應(yīng)用進(jìn)行分析，希望對中國石油煉化事業(yè)的發(fā)展起到積極的促進(jìn)作用。 </p> <p> 機(jī)械密封在流體機(jī)械中發(fā)揮著非常重要的作用，可以有效防止機(jī)械內(nèi)部的介質(zhì)流出泵外。其運行情況，對泵用機(jī)械運行的穩(wěn)定性有著非常直接的影響，在石油煉化生產(chǎn)過程中，發(fā)揮著非常重要的作用。各種流體機(jī)械在化工生產(chǎn)中，有著非常明顯的應(yīng)用，隨著石油煉化技術(shù)的高速發(fā)展，流體機(jī)械的應(yīng)用參數(shù)水平也在不斷提高，對機(jī)械性能要求也在不斷提高，轉(zhuǎn)軸密封的作用非常突出。我國對機(jī)械密封的研究開始較晚，從上個世紀(jì)80 年代，機(jī)械密封在石油煉化產(chǎn)業(yè)中才開始得到大規(guī)模的應(yīng)用。 </p><p> 油封密封不嚴(yán)而漏油的對策： </p> <p> 掌握和識別偽劣產(chǎn)品的基本知識，選購質(zhì)量、標(biāo)準(zhǔn)的油封。 </p> <p> 安裝時，若軸徑外表面粗糙度低或有銹斑、銹蝕、起毛刺等缺點，要用細(xì)砂布或油石打磨光滑；在油封唇口或軸徑對應(yīng)位置涂上清潔機(jī)油或潤滑油脂。 </p> <p> 油封外圈涂上密封膠，用硬紙把軸上的鍵槽部位包起來，避免劃傷油封唇口，用**工具將油封向里旋轉(zhuǎn)壓進(jìn)，千萬不能硬砸硬沖，以防油封變形或擠斷彈簧而失效；若出現(xiàn)唇口翻邊、彈簧脫落和油封歪斜時必須拆下重新裝入。應(yīng)該注意的是：當(dāng)軸徑?jīng)]有磨損和油封彈簧彈力足夠時，不要擅自收緊內(nèi)彈簧。應(yīng)用在機(jī)械上的油封一般工作條件惡劣、環(huán)境溫差大、塵埃多、機(jī)具振動頻繁使機(jī)件受力狀況不斷變化時，要勤檢查、保養(yǎng)和維護(hù)。 </p> <p> 如軸徑和軸承磨損嚴(yán)重；油封橡膠老化或彈簧失效等，應(yīng)及時進(jìn)行修理和更換相應(yīng)部件。 </p> <p> 對不正常發(fā)熱的部件或總成應(yīng)及時排除故障；避免機(jī)械超速、超負(fù)荷運轉(zhuǎn)，以防止油封唇口溫度升高、橡膠老化、唇口早期磨損等。 </p> <p> <br /> </p> <p> <br /> 機(jī)械密封的平衡程度β也影響著密封的磨損。一般情況下，平衡程度β=75%左右**適宜。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="南通容積泵密封銷售廠家,封"

在實際應(yīng)用中選了YG6- YG6, 一般連續(xù)運轉(zhuǎn)壽命在800Oh以上; </p> <p> 對間歇性的運轉(zhuǎn)設(shè)備,摩擦副選用碳化鎢或碳化硅對特種石墨。 </p> <p> 對金屬波紋管部分進(jìn)行適當(dāng)?shù)臒崽幚砟芟附訋淼臍堄鄳?yīng)力,以避免長期運行過程中產(chǎn)生疲勞破裂. </p> <p> 由于在低溫條件下,摩擦副端面的氣化對機(jī)械密封性能影響很大,除選取較適合的材料外,合理選取端面比壓,主要是波紋管的壓縮量,一般比通常使用中所給的壓縮量大15%～30%為宜。在機(jī)械密封元件靠近大氣側(cè)通入25℃左右的冷卻水,以改善摩擦副潤滑環(huán)境。機(jī)械密封是依靠彈性元件對動、靜環(huán)斷面的預(yù)緊力來對軸向端面進(jìn)行密封的，又稱為端面密封。蘇州化工泵密封生產(chǎn)廠家</p><p
