泵用機械密封按結(jié)構(gòu)分類的基本形式有單端面機械密封、雙端面機械密封和串聯(lián)機械密封。由一對密封端面組成的為單端面機械密封；由兩對密封端面組成的為雙端面機械密封；由兩套或兩套以E同向布置單端面機械密封組成的機械密封為串聯(lián)機械密封。下面主要分別說明兩種機械密封的結(jié)構(gòu)特點供了解單端面與雙端面機械密封的區(qū)別。1、單端面機械密封單端面機械密封結(jié)構(gòu)簡單，如圖單端面機械密封結(jié)構(gòu)圖所示、制造成本低廉，安裝、使用方便，一般用于油、水、有機溶劑及腐蝕性介質(zhì)。通常使用單端面密封的泵類產(chǎn)品有立式單級管道離心泵、臥式離心泵2、雙端面機械密封有壓雙重機械密封(雙端面機械密封)多數(shù)用于易燃、易爆、有毒、含顆粒及潤滑性差的介質(zhì)，通常使用時需配備密封輔助系統(tǒng)，即在兩端面間的密封腔中通入隔離流體，從而改善機械密封的潤滑和冷卻條件。使用雙端面機械密封的泵類產(chǎn)品有：氟塑料離心泵或者IH不銹鋼化工泵等3、單端面與雙端面機械密封零件及相應(yīng)術(shù)語密封環(huán)：機械密封中其端面垂直于旋轉(zhuǎn)軸線相互貼合并相對滑動的兩個環(huán)形零件稱密封環(huán)。密封端面：密封環(huán)在工作時與另一個密封環(huán)相貼合的端面。該端面通常是研磨面。旋轉(zhuǎn)環(huán)(動環(huán))：隨軸做旋轉(zhuǎn)運動的密封環(huán)。靜止環(huán)。通化MECP-65D3-S/SE7-62襄樊五二五機械密封襄樊五二五機械密封HTM-80D351。</p><div

機械密封是靠一對或數(shù)對垂直于軸作相對滑動的端面在流體壓力和補償機構(gòu)的彈力（或磁力）作用下保持貼合并配以輔助密封而達到阻漏的軸封裝置。水泵常用機械密封結(jié)構(gòu)如圖所示。由靜止環(huán)（靜環(huán)）1、旋轉(zhuǎn)環(huán)（動環(huán)）2、彈性元件3、彈簧座4、緊定螺釘5、旋轉(zhuǎn)環(huán)輔助密封圈6和靜止環(huán)輔助密封圈8等元件組成，防轉(zhuǎn)銷7固定在壓蓋9上以防止靜止環(huán)轉(zhuǎn)動。旋轉(zhuǎn)環(huán)和靜止環(huán)往往還可根據(jù)它們是否具有軸向補償能力而稱為補償環(huán)或非補償還。機械密封中流體可能泄漏的途徑有如圖1中的A、B、C、D四個通道。C、D泄漏通道分別是靜止環(huán)與壓蓋、壓蓋與殼體之間的密封，二者均屬靜密封。B通道是旋轉(zhuǎn)環(huán)與軸之間的密封，當(dāng)端面摩擦磨損后，它僅僅能追隨補償環(huán)沿軸向作微量的移動，實際上仍然是一個相對靜密封。因此，這些泄漏通道相對來說比較容易封堵。靜密封元件常用的有橡膠O形圈或聚四氟乙烯V形圈，而作為補償環(huán)的旋轉(zhuǎn)環(huán)或靜止環(huán)輔助密封，有時采用兼?zhèn)鋸椥栽δ艿南鹉z、聚四氟乙烯或金屬波紋管的結(jié)構(gòu)。A通道則是旋轉(zhuǎn)環(huán)與靜止環(huán)的端面彼此貼合作相對滑動的動密封，它是機械密封裝置中的主密封，也是決定機械密封性能和壽命的關(guān)鍵。因此，對密封端面的加工要求很高。</p><p> 所以也要根據(jù)不同的工作溫度選用不同種類的浸漬石墨。一般浸巴氏合金石墨適用溫度范圍小于150℃，浸樹脂石墨適用溫度范圍為170~200℃，浸銅、鋁、鉛的石墨可在小于400℃的工作條件下使用。動環(huán)組件應(yīng)盡可能選用膨脹系數(shù)相近的材料，以防止高溫下動環(huán)和動環(huán)座的連接松動。3、選擇金屬波紋管機械密封。金屬波紋管密封近年來在高溫密封中使用很多，并且取得了很好的效果。在該種機封中，金屬波紋管取代了普通機封中的彈簧，省去了動環(huán)輔助密封圈，不需要克服動環(huán)補償時與轉(zhuǎn)軸的摩擦和磨損，因此在高溫下使用，一般都能取得不錯的效果。二、低溫下的機械密封在煉油化工裝置中，低溫輸送的介質(zhì)一般都具有豁度小、潤滑性差、容易氣化的特點，而且介質(zhì)在氣化時大量吸熱，使周圍溫度急劇下降，造成空氣中水氣的凝結(jié)，導(dǎo)致端面及其周圍結(jié)冰，使端面貼合不嚴(yán)引起泄漏。同時，因潤滑性差，端面摩擦產(chǎn)生的熱量較多，若不能及時轉(zhuǎn)移，必然會加劇端面處的氣化，造成惡性循環(huán)，加速密封面的早期失效。另外，低溫密封的輔助密封圈在低溫下發(fā)硬失彈也容易導(dǎo)致泄漏。對低溫密封，除了選擇合適的輔助密封圈材質(zhì)外，還要注意以下幾點：1、改進密封結(jié)構(gòu)及正確選擇摩擦副材料。實踐證明。IH25S200Z襄樊五二五機械密封。</p><div

機械密封的設(shè)計就會不同，檢修工藝也會有所差別，機械密封檢修過程中總結(jié)出一些經(jīng)驗：機械密封要組裝，清掃檢查莫忘記。先看兩環(huán)后看軸，傷痕裂紋不要漏。在把膠圈看，氣孔直徑要看清。各種尺寸需測量，兩環(huán)間隙要調(diào)好。緊力一定要校核，小小彈簧是關(guān)鍵。螺栓受力要均勻，輕拿輕放好習(xí)慣。水泵機械密封是轉(zhuǎn)動機械本體密封有效的方式之一，其本身加工的精度比較高，尤其是動、靜環(huán)，如果拆裝方法不合適或使用不當(dāng)，裝配后的機械密封不但達不到密封的目的，而且會損壞集結(jié)的密封元件。機械密封拆卸時注意事項在拆卸機械密封時，嚴(yán)禁動用手錘和扁鏟，以免損害密封元件。如果在泵兩端都有機械密封時，則在拆卸過程中必須小心謹(jǐn)慎，防止顧此失彼。對工作過的機械密封，如果壓蓋松動時密封面發(fā)生移動的情況，則應(yīng)更換動靜環(huán)零件，不應(yīng)重新上緊繼續(xù)使用。因為在松動后，摩擦副原來運轉(zhuǎn)軌跡會發(fā)生改變，接觸面的密封性就很容易遭到破壞。如密封元件被污垢或凝聚物粘結(jié)，應(yīng)***凝結(jié)物后再進行機械密封的拆卸。采用機械密封的水泵有：化工泵，離心泵,多級泵,自吸泵及各種排污泵產(chǎn)品。LC500-630襄樊五二五機械密封。通化襄樊五二五機械密封LC500/630II</p><p
