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*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(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。浙江葉輪泵密封哪家比較便宜機械密封的密封面要有一定的比壓，從而達到密封的目的，兩端面的緊密緊密程度可以通過彈簧調(diào)節(jié)。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

油封是用于密封機械設備中旋轉(zhuǎn)軸的封油用密封元件，而腔體基本上是靜止的，所以油封又稱旋轉(zhuǎn)軸唇形密封圈。 </p> <p> <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> <p> <br /> </p> </p><p> 有害介質(zhì)時為了取得更好的密封效果，采用雙重密封，根據(jù)密封液系統(tǒng)壓力可分為有壓雙封(雙端面機械密封)和無壓雙封(串聯(lián)式機械密封)。 </p> <p> 有壓雙封密封液系統(tǒng)的壓力一般要比一級密封前的壓力高0.01-0.03MPa。這樣一級密封泄漏時，密封液會進入泵內(nèi)，確保了泵內(nèi)介質(zhì)不會泄漏到外界。由于密封液進入泵內(nèi)，密封液系統(tǒng)壓力、液位降低，可以實現(xiàn)密封的泄漏監(jiān)測和報警。 </p> <p> 無壓雙封密封系統(tǒng)內(nèi)的壓力一般為常壓或微壓，低于一級密封前的密封腔壓力。當一級密封泄漏時，泵內(nèi)介質(zhì)會進人密封液系統(tǒng)，導致密封液系統(tǒng)的壓力和液位升高，可以通過壓力開關或液位開關實現(xiàn)泄露監(jiān)測和報警。通過密封液系統(tǒng)來監(jiān)測雙端面機械密封失效與否，也是其區(qū)別于單端面機械密封**主要的形式之一。 </p> <p> <br /> 根據(jù)溫度及流體性質(zhì)，確定摩擦副和輔助密封材料，以及選擇潤滑、沖洗、保溫、冷卻機械密封循環(huán)保護系統(tǒng)等。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

在新增的水泵中全部采用了機械密封，與原有水泵的盤根密封形成了鮮明的對比：（1）機械密封與盤根密封在密封性能上，機械密封要比盤根密封漏泄量小的多，*為盤根密封漏泄量的1%。（2）使用壽命長，兩年以內(nèi)無需更換，以往盤根密封每60天左右就要進行一次更換。（3）消耗功率較少同比盤根密封省電5%以上。（4）減少了軸或軸承的磨損。 </p> <p> 通過摸索對比先后將車間的兩臺循環(huán)水泵、兩臺射水泵、凝結水泵共6臺泵進行了進行密封改造。改造后均收到了良好的效果。 </p> <p> 循環(huán)水泵（20HBA）在未改為機械密封前，每年至少要更換4次油盤根，每次更換量在1公斤左右，市場價格30元.，由于盤根磨損所致3年左右需更換一根水泵軸及配套軸瓦，費用在7000元左右，不計人工費用每臺水泵每年消耗在2500元左右。而改為機械密封后費用方面每臺泵的機械密封價格在600元左右，至少一個大修期在3年以上，由于摩擦阻力的降低使電耗每小時下降8度，全年節(jié)電在58000度，降低成本3萬元左右。因此機械密封于盤根密封相比優(yōu)勢十分明顯。 </p> <p> <br /> </p> <p> <br /> </p> 熱裂是高溫油泵，如油渣泵、回煉油泵、常減壓塔底泵等**常見的失效現(xiàn)象。浙江電動泵密封制造廠家</p><p style="text-indent:25px">根據(jù)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(nèi)裝式或外裝式?；窗矄渭壉妹芊饽募屹|(zhì)量好</p><p> <p> 在液泵的正常操作中，旋轉(zhuǎn)面和靜止面之間因填料盒中的液體所產(chǎn)生的壓力而使其保持在密封狀態(tài)，在起動和停機時，填料盒的壓力由彈簧產(chǎn)生的壓力維持(甚至可以由彈簧的壓力來代替)。 </p> <p> 大部分機械密封的設計采用較軟的材料來制作旋轉(zhuǎn)面，使其在較硬的靜止面上旋轉(zhuǎn)摩擦。多年來，**通用的組合是利用碳材料作為旋轉(zhuǎn)面，使其在陶瓷靜止面上運行。這類材料目前仍在普遍使用，但靜止面則選用不銹鋼或更硬的材料制作，例如碳化鎢或碳化硅。 </p> <p> 不管采用什么材料，總之在接觸面之間必須保持一層液體薄膜，以起到潤滑的作用。然而，在填料盒內(nèi)，采用彈簧負載和液體壓力相結合的方式，可以使密封面之間起到很好的密封作用。但密封壓力太高，則會影響接觸面之間形成液體薄膜，導致熱量增加和過早的磨損。如果密封壓力太低，接觸面之間的間隙增大，容易造成液體泄漏。 </p> <p> 密封制造廠正在不斷地努力提高接觸面的平直度，他們采用特殊的拋光板進行研磨。然后，采用單色光源的光柵板對其檢測。從這一觀點出發(fā)，對這些密封接觸面必須小心處理，并嚴格按照安裝說明，保證密封面得到適當?shù)谋Ｗo和正確就位，這一點是非常重要的。 </p> <p> <br /> </p> 淮安單級泵密封哪家質(zhì)量好</p><p
