當化工泵輸送介質(zhì)，對溫度和壓力不高時，一般選用非金屬密封墊片； </p> <p> 當化工泵輸送介質(zhì)為中壓高溫時，選用非金屬與金屬組合墊片。 </p> <p> 非金屬墊片在泵上應用**為普遍，其材料一般為紙、橡膠和聚四氟乙烯。當溫度不超過120℃，壓力在1.0Mpa以下時，一般選用青殼紙或模造紙墊片，南通容積泵密封供貨商。 </p> <p> 如果當化工泵輸送介質(zhì)為油，溫度在-30～110℃時，一般選用耐老化性能較好的丁晴橡膠。當當化工泵輸送介質(zhì)，在-50～200℃時，選用氟橡膠更為合適。因為它除了耐油耐熱外，機械強度大也是其主要特征。 </p> <p> 在化工泵中由于所輸送介質(zhì)具有腐蝕性，所以一般選用聚四氟乙烯做為墊片材料。隨著化工泵使用的領(lǐng)域越來越多次，所輸送介質(zhì)種類也越來越多，因此在選用墊片材質(zhì)時應查閱相關(guān)資料或通過實驗后再做出正確選擇。 </p> <p> <br />

<span style="font-size:12px;">機械的摩擦部分由于在機械運轉(zhuǎn)時有油進入，為防止這些油從機械的間隙中泄漏而使用油封，并且除了油以外還需要防止水與化學藥液的泄漏以及塵埃及土砂從外部侵入，這時候也要用到油封。</span> </p> <p> <span style="font-size:12px;">油封的密封狀態(tài)，一是油封外緣和腔體之間為靜態(tài)密封，同時保證油封外緣在腔體之間的可靠定位。二是油封密封唇和軸之間的密封狀態(tài)，當軸旋轉(zhuǎn)時為動態(tài)密封，當軸靜止時為靜態(tài)密封。各種影響因素的綜合作用及其相互作用，都對油封的密封性能和使用壽命產(chǎn)生了很大影響。</span> </p>

在機械行業(yè)中填料密封主要用作動密封,常用作離心泵、壓縮機、真空泵、攪拌機的轉(zhuǎn)軸密封。填料裝入填料腔以后,經(jīng)壓蓋螺絲對它作軸向壓縮,當軸與填料有相對運動時,由于填料的塑性,使它產(chǎn)生徑向力,并與軸緊密接觸。與此同時,填料中浸漬的潤滑劑被擠出,在接觸面之間形成油膜。由于接觸狀態(tài)并不是特別均勻的,接觸部位便出現(xiàn) </p> <p> 邊界潤滑狀態(tài),稱為”軸承效應”;而未接觸的凹部形成小油槽,有較厚的油膜,接觸部位與非接觸部位組成一道不規(guī)則的迷宮,起阻止液流泄漏的作用,此稱”迷宮效應”。這就是填料密封的機理。良好的密封在于維持“軸承效應”和”迷宮效應”。也就是說,要保持良好的潤滑和適當?shù)膲壕o，若潤滑不良,或壓得過緊都會使油膜中斷,造成填料與軸之間出現(xiàn)干摩擦,而后導致燒軸和出現(xiàn)嚴重磨損。因此,我們需要經(jīng)常對填料的壓緊程度進行調(diào)節(jié),使填料中的潤滑劑在運行一段時間而有所流失之后,再擠出一些潤滑劑,同時補償填料因體積變化所造成的壓緊力松弛。當然這樣經(jīng)常擠壓填料,而后將使浸漬劑枯竭,所以定期更換填料是必要的。此外,為了維持液膜和帶走摩擦熱,有意讓填料處有少量泄漏也是必要的。 </p><p> 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，其機械密封往往會出現(xiàn)各種問題，不僅影響機械的正常使用，還容易導致安全問題的發(fā)生。文章對石油煉廠常用機械密封的設(shè)計改進與應用進行分析，希望對中國石油煉化事業(yè)的發(fā)展起到積極的促進作用。 </p> <p> 機械密封在流體機械中發(fā)揮著非常重要的作用，可以有效防止機械內(nèi)部的介質(zhì)流出泵外。其運行情況，對泵用機械運行的穩(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。各種流體機械在化工生產(chǎn)中，有著非常明顯的應用，隨著石油煉化技術(shù)的高速發(fā)展，流體機械的應用參數(shù)水平也在不斷提高，對機械性能要求也在不斷提高，轉(zhuǎn)軸密封的作用非常突出。我國對機械密封的研究開始較晚，從上個世紀80 年代，機械密封在石油煉化產(chǎn)業(yè)中才開始得到大規(guī)模的應用。機械密封的輔助沖洗系統(tǒng)是非常重要的，它可以有效的保護密封面，起到冷卻、潤滑、沖走雜物等作用。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

原因二、安裝過松。觀察機封動、靜環(huán)平面，其表面有一層很薄的水垢，能夠擦去，表面基本無磨損，這是彈簧失去彈性及裝配不良造成，或電機軸向竄動造成。 </p> <p> 原因三、水質(zhì)差含顆粒。由于水質(zhì)差，含有小顆粒及介質(zhì)中鹽酸鹽含量高，形成磨料磨損機封的平面或拉傷表面產(chǎn)生溝槽、環(huán)溝等現(xiàn)象。 </p> <p> 處理辦法：改進水壓或介質(zhì)，更換機封。 </p> <p> 原因四、缺水運行造成干磨損壞。此現(xiàn)象多見于底閥式安裝形式進口處負壓，進水管有空氣，泵腔內(nèi)有空氣，泵開機后，機封的磨擦高速運轉(zhuǎn)時產(chǎn)生高溫，無法得到冷卻，檢查機封，彈簧張力正常，摩擦面燒焦發(fā)黑，橡膠變硬開裂。處理辦法：排盡管道及泵腔內(nèi)空氣，更換機械密封。各種密封其性能影響因素是不同的，如機械密封(填料密封等)影響因素有溫度、介質(zhì)、磨損、所承受壓力等。浙江管道泵密封廠家供應</p><p
