干熄焦余熱發(fā)電凝結(jié)水泵一般采用6N6型單級懸臂離心泵。泵的吸入口為水平軸向，泵的出口垂直向上，泵主要由泵體、葉輪、泵蓋、泵軸和懸架部件等零件組成，泵的軸承采用徑向球軸承和一組背對背的推力球軸承，每一組軸承用一個甩油環(huán)濺油潤滑。泵的軸封采用填料密封盒機械密封，并輔以外接的水封水進(jìn)行水封，以防止空氣漏入和漏水。泵的傳動通過彈性聯(lián)軸器由泵直接驅(qū)動。受泵入口壓力為負(fù)壓，廣州神通博格曼機械密封152，同時受汽輪機工況、以及操作、潤滑、維護等多種因素的影響，凝結(jié)水泵在運轉(zhuǎn)期間故障比較多，常見的有汽蝕、彈性聯(lián)軸器損壞、軸承損壞等。一、汽蝕1、簡易判斷方法在水泵入口處發(fā)出噪聲（類似碎石般的異音），嚴(yán)重時水泵入口的真空表、出口的壓力表、流量表和電流表急劇晃動。在汽輪機高負(fù)荷工況下達(dá)不到設(shè)計揚程。2、頻譜分析很容易在加速度譜中查看到葉片通過頻率和高頻抬起的底部噪聲，廣州神通博格曼機械密封152。下面以真空泵汽蝕時進(jìn)行舉例說明:(1)泵入口管道劇烈振動，噪音大，廣州神通博格曼機械密封152，嚴(yán)重時泵體拉桿都被振斷，開真空破壞門此現(xiàn)象可緩解；(2)采集了真空泵泵側(cè)非驅(qū)動端的振動加速度、速度、位移的頻譜與波形。①加速度高頻處底部噪聲抬起②加速度與速度頻譜均以葉輪通過頻率（工頻，18個葉片）225HZ為主。FBD神通博格曼機械密封。廣州神通博格曼機械密封152</p><div

沖洗液的流量、壓力不夠，沖洗口位置設(shè)計不合理等原因，也同樣達(dá)不到效果。常用的措施有：1.在條件允許的情況下，盡量設(shè)計輔助沖洗系統(tǒng)。沖洗壓力一般要求高于密封腔壓力，密封腔壓力要根據(jù)每種泵的結(jié)構(gòu)形式、系統(tǒng)壓力等因素來計算。軸封腔壓力很高或者壓力幾乎接近該密封使用極限時，也可由密封腔引液體至低壓區(qū)，使軸封液體流動以帶走摩擦熱。2.根據(jù)每種泵的操作條件，合理地配置管路和附件。如冷卻器、孔板、過濾器、閥門、流量指示器、壓力表、溫度等。實際上密封的可靠性和壽命，在很大程度上取決于密封輔助系統(tǒng)的配置，另外泵軸、軸套、泵體、密封腔體的加工精度不夠等原因的存在對機械密封的密封效果也是很不利的，在這些方面應(yīng)該做到嚴(yán)格把關(guān)。（四）振動偏大及消除措施機械密封振動偏大往往不是機械密封自身的原因，而是泵軸設(shè)計不合理、加工精度不夠、靠背輪的平行度偏大、徑向力大等原因，消除泵振動措施有：泵、電機、底座、現(xiàn)場管路等輔助設(shè)備在現(xiàn)場安裝時，要嚴(yán)格把關(guān)，消除振動源。（五）泵氣蝕的原因及改進(jìn)措施離心泵葉輪入口處是泵內(nèi)壓力小的地方，當(dāng)此處的壓力等于或低于工作溫度下被輸送液體的飽和蒸汽壓1pt時，液體就會沸騰汽化，產(chǎn)生大量氣泡。平頂山104神通博格曼機械密封福州神通博格曼機械密封。</p><div

什么是機械密封？機械密封又稱為端面密封，其至少有一對垂直于旋轉(zhuǎn)軸線的端面，該端面在流體壓力及補償機械外力（或磁力）的作用下，加之輔助密封的配合，與另一端面保持貼合并相對滑動，從而防止流體泄漏。由于端面的緊密貼合，使密封端面之間形成微小間隙，當(dāng)有介質(zhì)通過此間隙時，形成極薄的液膜，造成阻力防止泄漏，并且潤滑端面，獲取密封的效果。機械密封因其密封性能好，運行穩(wěn)定、泄漏少，摩擦功耗低，使用周期長，對軸磨損很小，并能滿足多種工況要求，因此被***應(yīng)用。它有那幾部分組成？（1）靜止環(huán)及旋轉(zhuǎn)環(huán)（動環(huán)與靜環(huán)），通常為研磨面，又稱為摩擦副。（2）以彈性元件為主的補充緩沖機構(gòu)。（3）輔助密封圈。（4）使動環(huán)和軸一起旋轉(zhuǎn)的傳動部件。機械密封在哪些設(shè)備常用？按設(shè)備可分為耐腐蝕泵、化工泵、氟塑料離心泵、反應(yīng)釜、離心機、風(fēng)機、潛水泵電機、冷凍機、內(nèi)燃機、冷卻水泵、耐酸堿泵等以及其它設(shè)備上使用，機械密封目前使用相當(dāng)廣。機械密封作用原理分類：（1）密封端面的對數(shù)：單端面，雙端面，多端面。其中雙端面又分為軸向雙端面和徑向雙端面。（2）按照作用于密封端面流體壓力為卸載或不卸載可分為：非平衡式、部分平衡式、全平衡式。。</p><p> 接觸面破壞，軸上各部件間有間隙，軸頭螺紋過長等都會導(dǎo)致軸間泄漏。鎖母鎖緊過度只會導(dǎo)致軸間墊過早失效，相反適度鎖緊鎖母，使軸間墊始終保持一定的壓縮彈性，在運轉(zhuǎn)中鎖母會自動適時鎖緊，使軸間始終處于良好的密封狀態(tài)。、新的比舊的好相對而言，使用新機械密封的效果好于舊的，但新機械密封的質(zhì)量或材質(zhì)選擇不當(dāng)時，配合尺寸誤差較大會影響密封效果；在聚合性和滲透性介質(zhì)中，靜環(huán)如無過度磨損，還是不更換為好。因為靜環(huán)在靜環(huán)座中長時間處于靜止?fàn)顟B(tài)，使聚合物和雜質(zhì)沉積為一體，起到了較好的密封作用。、拆修總比不拆好一旦出現(xiàn)機械密封泄漏便急于拆修，其實，有時密封并沒有損壞，只需調(diào)整工況或適當(dāng)調(diào)整密封就可消除泄漏。這樣既避免浪費又可以驗證自己的故障判斷能力，積累維修經(jīng)驗提高檢修質(zhì)量。5、結(jié)束語以上總結(jié)了機械密封比較常見的滲漏原因和維護時的幾個常見的誤區(qū)。只有充分了解機械密封的結(jié)構(gòu)和常見的一些泄漏現(xiàn)象，正確的分析導(dǎo)致各種泄漏的原因，才能對癥下藥進(jìn)行治理，才能保證安全生產(chǎn)。104神通博格曼機械密封。</p><div

泵開機后，機封的磨擦高速運轉(zhuǎn)時產(chǎn)生高溫，無法得到冷卻，檢查機封，彈簧張力正常，摩擦面燒焦發(fā)黑，橡膠變硬開裂。處理辦法：排盡管道及泵腔內(nèi)空氣，更換機械密封。5氣蝕。氣蝕主要產(chǎn)生于熱水泵。由于介質(zhì)是熱水，水溫過高產(chǎn)生蒸汽，管道內(nèi)的汽體進(jìn)入泵腔內(nèi)高處，這部份的汽體無法排除，從而造成缺水運行，機封干磨失效，氣蝕裝自動排氣閥，更換機封。水泵處理方法1機械密封處滲?水的第一種可能性是機封的動、靜環(huán)平面磨損。而造成機封的動、靜環(huán)平面磨損的原因有六個方面：原因一、安裝過緊。觀察機械密封的動靜環(huán)平面，如有嚴(yán)重?zé)宫F(xiàn)象，平面發(fā)黑和很深的痕跡，密封橡膠變硬，失去彈性，這種現(xiàn)象是由于安裝過緊造成的。處理辦法：調(diào)整安裝高度，葉輪發(fā)裝后，用螺絲刀拔動彈簧，彈簧有較強的張力，松開后即復(fù)λ，有24MM的移動距離即可。原因二、安裝過松。觀察機封動、靜環(huán)平面，其表面有一層很薄的水垢，能夠擦去，表面基本無磨損，這是彈簧失去彈性及裝配不良造成，或電機軸向竄動造成。原因三、水質(zhì)差含顆粒。由于水質(zhì)差，含有小顆粒及介質(zhì)中鹽酸鹽含量高，形成磨料磨損機封的平面或拉傷表面產(chǎn)生溝槽、環(huán)溝等現(xiàn)象。處理辦法：改進(jìn)水壓或介質(zhì)，更換機封。婁底神通博格曼機械密封。上海神通博格曼機械密封155</p><p
