化學(xué)工業(yè)所采用的傳統(tǒng)密封設(shè)計(jì)，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?yàn)閺椈苫虿y密封裝置與主軸一起旋轉(zhuǎn)。比較新穎的設(shè)計(jì)，其彈簧或波紋密封裝置安裝于靜止面上。在現(xiàn)在的機(jī)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。早期設(shè)計(jì)的許多機(jī)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(qiáng)的密封力。密封的作用依靠主軸的旋轉(zhuǎn)來繃緊彈簧卷，大連雙龍機(jī)械密封。采用多個(gè)較小的彈簧，可對密封面產(chǎn)生比較平均的負(fù)荷壓力，因此對堵塞具有更大的敏感性。后期設(shè)計(jì)的密封(見圖2)采用一系列較小的彈簧，排列于主軸的周圍，可對密封面產(chǎn)生比較均勻的負(fù)荷壓力。由于較小的彈簧可以事先安裝，因此大部分這類密封完全與所泵的液體相隔離。金屬波紋管密封裝置一般應(yīng)用于腐蝕性較強(qiáng)的液體。對許多腐蝕性較強(qiáng)的應(yīng)用領(lǐng)域，通用的設(shè)計(jì)是采用金屬波紋管密封裝置。該波紋管由一系列的金屬圓盤焊接而成，形成一個(gè)防止?jié)B漏的波紋密封裝置(見圖3)。采用這一裝置可使密封面之間的密封壓力更加均勻，大連雙龍機(jī)械密封，大連雙龍機(jī)械密封，而且在密封面上不需要增加二次密封，這樣自然就不會產(chǎn)生任何腐蝕磨損現(xiàn)象。一般來說，雖然其主要的密封壓力依賴于填料盒本身的壓力。南通輕型機(jī)械密封件。大連雙龍機(jī)械密封</p><div

機(jī)械密封安裝一、安裝前的準(zhǔn)備工作和注意事項(xiàng)1.從包裝箱中取出要安裝的機(jī)械密封放在干凈的平面上，保護(hù)好密封面，并將所有標(biāo)簽、證件整理后待檢;2.檢查機(jī)械密封的型號、規(guī)格和材質(zhì)證明，零件的數(shù)量，動、靜環(huán)配對是否符合圖紙要求，零件上有無制造廠的識別標(biāo)記;3.檢查各零件的表面質(zhì)t，特別是動、靜環(huán)的密封端面有無碰傷、劃痕，如有損壞，必須進(jìn)行修復(fù)或更換，零件表面必須清洗干凈，在動、靜環(huán)密封端面上涂一層油;4.檢查石墨環(huán)、城充聚四氛乙烯壞及組裝的動、靜環(huán)的水壓試驗(yàn)證明，如果沒有試壓證明，安裝前要補(bǔ)做水壓試驗(yàn)，試驗(yàn)壓力照第六章***節(jié)規(guī)定;5.并圈彈簧傳動的機(jī)械密封，特別要注意彈簧的旋向，其旋向應(yīng)與軸轉(zhuǎn)動方向相同，使彈簧越旋越緊，就是按定出的軸旋轉(zhuǎn)方向，從靜環(huán)朝動環(huán)方向看，順時(shí)針方向需要右旋彈簧，逆時(shí)針方向則要左旋彈簧.使用小彈簧時(shí)，要檢查各組彈簧的圈數(shù)和自由高度;6.對安裝機(jī)械密封的主機(jī)按技術(shù)要求檢查軸向串量、徑向跳動、有關(guān)的垂直度、同心度、表面粗糙度、配合尺寸和對泵的聯(lián)軸節(jié)要求等.(1)軸向串量:要求不超過，一般在，軸向串量過大，使機(jī)械密封彈簧比壓不穩(wěn)定，引起密封端面過全磨損或泄漏，由于軸的抖動而使密封破損。大連雙龍機(jī)械密封錫山區(qū)109機(jī)械密封件。</p><div

沖洗液可以是熱水或蒸汽。九、機(jī)械密封典型失效原因分析（一）機(jī)械密封本身問題1、鑲裝不到位或不平整。2、載荷系數(shù)太大或端面比壓設(shè)計(jì)不合理。3、材質(zhì)選用不當(dāng)。4、密封面不平。5、密封面太寬或太窄。（二）輔助系統(tǒng)問題1、工況條件復(fù)雜，但沒有沖洗等輔助設(shè)施。2、沖洗管堵塞。3、冷卻管結(jié)垢。（三）介質(zhì)及工作條件問題1、介質(zhì)腐蝕性強(qiáng)。2、介質(zhì)中有固體顆粒。3、設(shè)備抽空。4、密封面結(jié)晶。5、介質(zhì)粘度太大。（四）泵的問題1、軸的加工精度不佳、串軸、跳動、安裝間隙過大。2、泵開啟后振動太大。3、壓蓋墊環(huán)不佳。4、密封箱不平。5、機(jī)械密封安裝沒有達(dá)到應(yīng)有的壓縮量。十、常見的滲漏現(xiàn)象機(jī)械密封滲漏的比例占全部維修泵的50%以上，機(jī)械密封的運(yùn)行好壞直接影響到水泵的正常運(yùn)行，現(xiàn)總結(jié)分析如下：1、周期性滲漏（1）泵轉(zhuǎn)子軸向竄動量大，輔助密封與軸的過盈量大，動環(huán)不能在軸上靈活移動。在泵翻轉(zhuǎn)，動、靜環(huán)磨損后，得不到補(bǔ)償位移。對策：在裝配機(jī)械密封時(shí)，軸的軸向竄動量應(yīng)小于0．1mm，輔助密封與軸的過盈量應(yīng)適中，在保證徑向密封的同時(shí)，動環(huán)裝配后保證能在軸上靈活移動（把動環(huán)壓向彈簧能自由地彈回來）。（2）密封面潤滑油量不足引起干摩擦或拉毛密封端面。新吳區(qū)波紋管機(jī)械密封件。</p><div

一、機(jī)械密封概述機(jī)械密封（端面密封）是一種用來解決旋轉(zhuǎn)軸與機(jī)體之間密封的裝置。它是由至少一對垂直于旋轉(zhuǎn)軸線的端面的流體壓力和補(bǔ)償機(jī)構(gòu)彈力（或磁力）的作用及輔助密封的配合下保持貼合下并相對滑動而構(gòu)成防止流體泄漏的裝置，常用于泵、壓縮機(jī)、反應(yīng)攪拌釜等旋轉(zhuǎn)式流體機(jī)械，也用于齒輪箱、船舶尾軸等密封。因此，機(jī)械密封是一種通用的軸封裝置。機(jī)械密封結(jié)構(gòu)多種多樣，常用的機(jī)械密封結(jié)構(gòu)是端面密封。端面密封的靜環(huán)、動環(huán)組成一對摩擦副，摩擦副的作用是防止介質(zhì)泄漏。它要求靜環(huán)、動環(huán)，具有良好的耐磨性，動環(huán)可以在軸向靈活的移動，自動補(bǔ)償密封面磨損，使之與靜環(huán)良好的貼合；靜環(huán)具有浮動性，起緩沖作用。為此，密封面要求有良好的加工質(zhì)量，保證密封副有良好的貼合性能。構(gòu)成機(jī)械密封的基本元件有靜環(huán)、動環(huán)、壓蓋、推環(huán)、彈簧、定位環(huán)、軸套、動環(huán)密封圈、靜環(huán)密封圈軸套密封圈等。彈性元件（彈簧、波紋管）它主要起預(yù)緊、補(bǔ)償和緩沖的作用，要求始終保持足夠的彈性來克服輔助密封和傳動件的摩擦和動環(huán)等的慣性，保證端面密封副良好的貼合和動環(huán)的追隨性，材料要求耐腐蝕、耐疲勞。輔助密封。無錫橡膠波紋管機(jī)械密封件。大連雙龍機(jī)械密封</p><p

2)、對安裝機(jī)械密封時(shí)壓縮量過大，導(dǎo)致摩擦副端面嚴(yán)重磨損、擦傷；3)、動環(huán)密封圈過緊，彈簧無法調(diào)整動環(huán)的軸向浮動量；4)、靜環(huán)密封圈過松，當(dāng)動環(huán)軸向浮動時(shí)，靜環(huán)脫離靜環(huán)座；5)、工作介質(zhì)中有顆粒狀物質(zhì)，運(yùn)轉(zhuǎn)中進(jìn)人摩擦副，探傷動、靜環(huán)密封端面；6)、設(shè)計(jì)選型有誤，密封端面比壓偏低或密封材質(zhì)冷縮性較大等。上述現(xiàn)象在試運(yùn)轉(zhuǎn)中經(jīng)常出現(xiàn)，有時(shí)可以通過適當(dāng)調(diào)整靜環(huán)座等予以消除，但多數(shù)需要重新拆裝，更換密封。3、由于兩密封端面失去潤滑膜而造成的失效a）因端面密封載荷的存在，在密封腔缺乏液體時(shí)啟動泵而發(fā)生干摩擦；b）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；c）如介質(zhì)為易揮發(fā)性產(chǎn)品，在機(jī)械密封冷卻系統(tǒng)出現(xiàn)結(jié)垢或阻塞時(shí)，由于端面摩擦及旋轉(zhuǎn)元件攪拌液體產(chǎn)生熱量而使介質(zhì)的飽和蒸汽壓上升，也造成介質(zhì)壓力低于其飽和蒸汽壓的狀況。4、由于腐蝕而引起的機(jī)械密封失效a）密封面點(diǎn)蝕，甚至穿透。b）由于碳化鎢環(huán)與不銹鋼座等焊接，使用中不銹鋼座易產(chǎn)生晶間腐蝕；c）焊接金屬波紋管、彈簧等在應(yīng)力與介質(zhì)腐蝕的共同作用下易發(fā)生破裂。5、由于高溫效應(yīng)而產(chǎn)生的機(jī)械密封失效a）熱裂是高溫油泵。大連雙龍機(jī)械密封</p><p
