高溫重質(zhì)油泵的介質(zhì)具有以下共同的特點: </p> <p> 溫度高:一般在340一400℃; </p> <p> 介質(zhì)粘度大:在溫度下一般運動粘度為(12一180)X 10一6m/s; </p> <p> 介質(zhì)有顆粒:如催化劑、焦炭、含有砂粒等其他雜質(zhì)。 </p> <p> 對于高溫重油介質(zhì)泵用機械密封?，F(xiàn)在各個企業(yè)都采用焊接金屬波紋管械密封。現(xiàn)在使用情況較好的有DBM型、XL-604/606/609型、YH-604/606/609型等。波紋管材料采用八AM350、INCONEL718、哈氏B、C等不銹鋼;耐腐蝕高溫合金等，有的波片采用雙層結(jié)構(gòu)，使其承壓力從2MPa上升到5MPa，這些都有效解決了波紋紋管的失彈問題。 </p><p> 高溫?zé)嵊捅?</p> <p> 對于煉油裝置中有一部分泵的介質(zhì)溫度均在200°C以上，有的甚至超過300 °C，此時若機械密封沖洗方案的選擇為PLAN53B，應(yīng)多加考慮PLAN53B 系統(tǒng)中蓄能器皮囊的耐溫問題。通常情況下，蓄能器皮囊若為普通橡膠材質(zhì)，耐溫不超過120 °C，即使是氟橡膠耐溫也不超過200 °C。 </p> <p> API 682 中PLAN53B 系統(tǒng)的布置方式如圖1 所示，從圖中可以看出高溫的密封隔離液從密封腔直接經(jīng)過蓄能器，然后再經(jīng)過冷卻器，再回到密封腔。此種布置方式在隔離液溫度升高之后，可能會導(dǎo)致蓄能器內(nèi)介質(zhì)溫度升高，致使皮囊失效。介質(zhì)的低于飽和蒸汽壓力，使得端面液膜發(fā)生閃蒸，喪失潤滑。</p><div

主軸的軸向和徑向運動需要與彈簧之間保持一定的靈活性，以保證接觸面之間的密封。然而，只能提供一定程度的靈活性。液泵的機械狀況及其長度直徑比(一種主軸的直徑與其延伸長度之比的衡量方式，比值越低越好)對密封的可靠性起著重要的作用。密封的靈活性一般由一個大型主彈簧和一系列小彈簧或波紋密封裝置提供保證。 </p> <p> <span style="font-size:12px;">化學(xué)工業(yè)所采用的傳統(tǒng)密封設(shè)計，其密封壓力施加于旋轉(zhuǎn)面上，這種密封稱之為旋轉(zhuǎn)密封，因為彈簧或波紋密封裝置與主軸一起旋轉(zhuǎn)。比較新穎的設(shè)計，其彈簧或波紋密封裝置安裝于靜止面上。在現(xiàn)在的機械密封上，上述兩種密封方式都有非常普遍的應(yīng)用，這樣對于安裝具有一定的靈活性。</span> </p> <p> <span style="font-size:12px;">早期設(shè)計的許多機械密封采用單一的大型彈簧圍繞主軸排列，在液泵起動過程中，可為密封面提供很強的密封力。密封的作用依靠主軸的旋轉(zhuǎn)來繃緊彈簧卷。</span> 在機泵的實際使用過程中，一定要對機泵進行合理使用，盡量避免對機泵進行超負荷運行。南京單級泵密封廠家批發(fā)價格</p><p

由于在低溫條件下,摩擦副端面的氣化對機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。南京單級泵密封廠家批發(fā)價格</p><p>
