液態(tài)烴介質是一種低溫液化氣體,具有低沸點、低黏度、高蒸氣壓等特性。在這種工況下使用的機械密封，密封件材料會出現冷脆性，大氣中的水氣會在密封裝置的大氣側面上凍結，南通單級泵密封廠家價格，摩擦副端面液膜容易氣化等。尤其是當介質稍有泄漏，漏出的液態(tài)烴在大氣側立即氣化，帶走大量的熱，南通單級泵密封廠家價格，機械密封環(huán)境溫度急劇下降，一般的密封材料，如橡膠或聚四氟乙烯普遍變脆，導致密封失效，泄漏增大，南通單級泵密封廠家價格。 </p> <p> <br /> </p> <p> 根據實際經驗,使用金屬波紋管機械密封比較好,主要表現在用金屬波紋管和柔性石墨代替輔助密封圈,解決了密封圈材料發(fā)生冷脆而失彈及緩沖作用的問題,如用DBM型、YH604/606/609型等。在液態(tài)烴泵上使用波紋管機械密封時應注意: </p> <p> 金屬波紋管材料選用耐低溫、韌性好的Hastelloy-C(耐熱鎳基金),AM350,Carpenter20 等; </p> <p> 合理的結構設計能保證機械密封在高速運轉的情況下不破壞密封端面和波紋管組件; </p> <p> 合理的端面接觸比壓能保證機械密封的密封性能和避免過早的失效; </p> <p> 合理的摩擦副材料能保證機械密封在低溫條件下正常的摩擦性能和密封性能, 避免因磨損過快而過早的失效; 因端面密封載荷的存在，在密封腔缺乏液體時啟動泵而發(fā)生干摩擦。南通單級泵密封廠家價格</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="南通單級泵密封廠家價格,封"

<p> 金屬波紋管旋轉結構 </p> <p> 旋轉波紋管密封在旋轉離心力作用下可以自身清洗波紋管，減少波紋管**沉積和內側結焦，并能防止因急冷造成的波紋管變形。泵類設備轉速一般為2950r/min，機械密封線速度遠小于25m/s,因此，可以選用旋轉結構。 </p> <p> 密封結構形式采用開槽斜面擠緊軸套 </p> <p> 這種定位傳動可靠，安裝拆卸方便且不傷軸。并設置有限位板，便于泵外調整密封的壓縮量。波紋管內徑一處設一45℃斜角，以分散應力，延長波紋管壽命。輔助密封采用柔性石墨替代合成橡膠，可以承受高達425℃的高溫。 </p> <p> 摩擦副材料的選取 </p> <p> 對摩擦副材料的選取我們采用“硬對硬”結構，起初動靜環(huán)我們選擇了SiC-WC，但是運轉一段時間發(fā)現動環(huán)出現肯邊現象。改用YG6-YG6之后，設備運轉一直正常。 </p> <p> <br /> 南通化工泵用密封供應商選擇合適的密封件材質和液壓油，以及對工作溫度的適應性，對油的相容性。</p><div style="width:100%;text-align:

隨著時代的高速發(fā)展，對石油資源的需求量不斷增加，石油煉廠的生產任務越來越重。泵用機械在石油煉廠生產過程中發(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部的介質流出泵外。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中，有著非常明顯的應用，隨著石油煉化技術的高速發(fā)展，流體機械的應用參數水平也在不斷提高，對機械性能要求也在不斷提高，轉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業(yè)中才開始得到大規(guī)模的應用。 </p><p> 防止工作介質從泵內泄漏出來或者防止外界雜質或空氣侵入到泵內部的裝置或措施稱為密封，被密封的介質一般為液體、氣體或粉塵。 </p> <p> 造成泄漏的原因主要有兩個方面：一是密封面上有間隙。二是密封部位兩側存在壓力差，消除或減小任何一個因素都可以阻止或減小泄漏，達到密封的目的。泵的設計壓力和使用壓力是客觀存在不能減小，所以泵的密封該解決的是消除或減小密封面之間的間隙。這種間隙包括密封面之間的間隙和密封裝置本生內部的間隙。 </p> <p> <br /> 根據安裝密封的有效空間，確定采用多彈簧或單彈簧或波形彈簧，內裝式或外裝式。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="南通單級泵密封廠家價格,封"

第一種冷卻形式由水泵的出口或高壓端，將輸送的干凈介質，直接沖洗密封端面，然后進入泵腔內，通過介質的不斷循環(huán)，將磨擦端面的的磨擦熱帶走達到冷卻的效果。 </p> <p> 第二種冷卻方式在第一種冷卻形式的基礎上在靜環(huán)的背部增加一冷卻水套，冷卻效果有所改善，并可以沖洗，收集泄露出來的液體。當密封介質溫度＞150℃時除了在冷卻水套中通過冷卻水及靜環(huán)背部冷卻外，應采取強制冷卻措施。即從泵出口的干凈介質應預先經熱交換器冷卻至50℃時。再進入密封腔冷卻沖洗，該形式是冷卻效果**良好的一種。 </p> <p> 如介質中含有顆粒或雜質，必須采用過濾措施，把常溫干凈沖洗液輸入密封腔內。 O形密封圈雖然密封可靠，但如果不注意使用條件，也會發(fā)生泄漏。鹽城管道泵密封銷售廠家</p><p style="text-indent:25px">密封件的存放室溫比較好在30℃以下，避免密封件產生高溫老化。南通單級泵密封廠家價格</p><p> 雙重密封和液體阻隔裝置 </p> <p> 采用雙重密封面的密封來代替單一的密封件具有更高程度的防漏特性。這類雙重密封大都應用于揮發(fā)性強、危險和潤滑性很差的液體。 </p> <p> <span style="font-size:12px;"> 雙重密封一般有三種設計型式，每種型式都要求在雙重密封面之間使用一種液體阻隔系統(tǒng)，以防止液體或氣體外泄。比較常用的低成本雙重密封是一種以背靠背方式安裝的密封，其旋轉密封面以相反的方向排列。它往往需要一種阻隔液體，其壓力應高于填料盒壓力，大約為20psi，這樣就可保證內部的密封始終能得到阻隔液體的潤滑，而且也可保證密封面達到一定的密封壓力。</span> 南通單級泵密封廠家價格</p><p
