安徽朗慧潔凈科技有限公司是阿法拉伐授權(quán)經(jīng)銷商，技術(shù)人員編寫了本章對阿法拉伐機械密封的選型和構(gòu)造進行了***的知識普及，涵蓋了在阿法拉伐離心泵、液環(huán)泵和凸輪轉(zhuǎn)子泵上使用的軸封裝置。除了軸封外，本章未過多介紹其它的**密封，如在泵頭和齒輪箱上使用的O形圈和唇形密封。阿法拉伐機械密封價格很高，但是原裝的機械密封質(zhì)量和品牌效應(yīng)對于價格來說，已經(jīng)微不足道?！氨玫钠焚|(zhì)取決于其軸封”泵應(yīng)用成功與否，在很大程度上要取決于是否選擇和使用了適當?shù)牧黧w密封裝置。正像我們所知道的，沒有哪一種泵既可以適用于各種流體和應(yīng)用，同時又能滿足不同的市場需求和法律規(guī)定。對流體密封裝置來說，情況也是如此。從泵制造商當前有大量的軸封配置（包括機械式和壓蓋式）可供選擇就可以清楚地看出這一點。在阿法拉伐離心泵、液環(huán)泵和凸輪轉(zhuǎn)子泵中使用的軸封裝置包括：?機械密封（請參閱）。-單端式，外裝。-單端式，內(nèi)裝。-單端式，外部注水沖洗。-單端式，內(nèi)裝，用于產(chǎn)品循環(huán)或外部注水沖洗。-雙端式，與內(nèi)部密封“背靠背”外裝，用于注水沖洗。離心泵和液環(huán)泵只有1個軸封，而凸輪轉(zhuǎn)子泵則至少使用2個軸封（一根軸一個）。通常而言，所有軸封都處于壓力之下。青島CLS20709-722231格蘭富機械密封件天津格蘭富機械密封件。</p><div

沖洗液可以是熱水或蒸汽。九、機械密封典型失效原因分析（一）機械密封本身問題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)計不合理。3、材質(zhì)選用不當。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。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、機械密封安裝沒有達到應(yīng)有的壓縮量。十、常見的滲漏現(xiàn)象機械密封滲漏的比例占全部維修泵的50%以上，機械密封的運行好壞直接影響到水泵的正常運行，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，得不到補償位移。對策：在裝配機械密封時，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，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。</p><p> 失效后也容易發(fā)現(xiàn)，本文不再贅述。螺紋密封螺紋密封在泵上一般有兩種形式，一種是螺紋聯(lián)接墊片密封，一種是螺紋加填充濟密封，二者皆用于小直徑螺紋連接的密封場合。螺紋聯(lián)接墊片密封的密封件是墊片，而螺紋只起提供壓緊力的作用。密封的效果除了墊片的本身性能外。密封面的粗糙度以及與螺紋孔的相對幾何位置精度對密封效果影響也很大。于由密封墊片在擰緊螺紋時不僅承受壓緊力，還承受扭矩，使墊片產(chǎn)生變形甚至損壞，因此，當墊片為非金屬時，一般只適用于壓力不高的場合，如果墊片為金屬則適用壓力可達30Mpa以上。泵上經(jīng)常使用的絲堵，則是另一種螺紋密封形式。由于考慮到絲堵制造的經(jīng)濟性，一般單靠螺紋的配合不能起到密封作用，往往用生膠帶，密封膠等填充物填充螺紋的密封間隙。其承壓能力取決于螺紋的制造精度和材質(zhì)，與絲堵和螺紋孔的配合形式?jīng)]有關(guān)系。螺紋孔與絲堵無論采用'錐對錐'還是'柱對錐'，密封效果相同，只是使用地域不同而已。我國目前兩種形式同等采用。影響密封效果的常見原因是在加工螺紋底孔時尺寸偏大，使螺紋牙形變短，牙頂變寬，造成密封面減小，當密封壓力升高后產(chǎn)生泄漏，甚至將絲堵壓出。橋東區(qū)格蘭富機械密封件。</p><div

機械密封是利用兩個平面互相摩擦運行的原理，達到密封的目的。旋轉(zhuǎn)密封面安裝于液泵的主軸上，而固定密封面安裝于密封壓蓋內(nèi)。由于一個密封面是運動的，而另一個密封面是靜止不動的，因此將這類密封稱之為動態(tài)密封。圖1旋轉(zhuǎn)面與靜止面之間的密封是決定密封性能關(guān)鍵的因素?；A(chǔ)的機械密封如圖1所示，其中有4個泄漏通路需要密封：1.密封面之間的通路;2.旋轉(zhuǎn)面與主軸之間的通路;3.固定面與壓蓋之間的通路;4.壓蓋與填料盒之間的通路。后兩種泄漏通路一般采用靜態(tài)密封，因為兩部分之間不存在相對運動。這部分的密封通常都稱之為三次密封，其密封材料為墊片或與工藝流程液體相適應(yīng)的O型密封圈。在較老的密封設(shè)計中，位于旋轉(zhuǎn)面下的二次密封留有一定的間隙，可在主軸上前后運動，因此易于引起磨損和過早失效。然而在較新的密封設(shè)計中，二次密封處于靜止狀態(tài)，因此可避免在主軸上出現(xiàn)磨損腐蝕問題。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)。大部分機械密封的設(shè)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。南昌格蘭富機械密封件。青島CLS20709-722231格蘭富機械密封件</p><p
