隨著現(xiàn)代石油、化工、冶金、原子能、電子、宇航技術(shù)的發(fā)展，對不同用途的高壓、超高壓、高真空、超高真空，甚至極高真空設(shè)備的密封要求越來越高。其中有的結(jié)構(gòu)復(fù)雜，內(nèi)部有很多管道和傳動機構(gòu)；有的體積很大，達幾百立方米，甚至數(shù)千立方米。在這些設(shè)備中管道的總長度可達幾公里，焊縫、密封連接的總長度可達數(shù)十公里，檢漏工作量十分巨大。由于實際上很難制造出沒有泄漏的裝置，且從某種意義上真正實現(xiàn)無泄漏也是不可能的，因此，一般情況下，對制造出的設(shè)備均應(yīng)進行檢漏試驗。而無論采用哪種檢漏方法，總要花費一定的時間、人力、物力和財力，故進行檢漏試驗時，一定要正確理解和使用檢漏方法，盡量減少“漏診和誤診”，并盡可能從工程或成套裝置的準備、設(shè)計、加工、安裝、試運轉(zhuǎn)、正式運轉(zhuǎn)等各階段對密封問題作周密的考慮，采取各種有效措施，減少泄漏。以下對裝置在設(shè)計、制造、安裝調(diào)試以及運行過程中的泄漏預(yù)測與防止以及檢漏程序作一說明。項目準備階段一、項目準備階段需考慮的主要問題在裝置制造、購買、檢查階段，必須充分重視密封問題，特別是項目準備階段，即在考慮制作和購買什么樣裝置才能符合使用要求時，更應(yīng)加倍重視。青島凱泉泵用機械密封KQWH40-200AZQ3650C-6凱泉泵用機械密封。</p><div

即軸旋轉(zhuǎn)方向應(yīng)使彈簧越來越緊，否則會造成密封失效，彈簧旋向的選擇由下述方法確定：由靜環(huán)向動環(huán)看，軸順時針旋轉(zhuǎn)用右旋彈簧，反之，則選用左旋彈簧。3、機械密封的安裝方法機械密封部件無論從制造精度上或安裝精度上要求都很嚴格，如果安裝不當，就會影響密封的壽命和密封性能，嚴重時將會使密封迅速失效。(1)安裝前的準備工作及安裝注意事項①檢查要進行安裝的機械密封的型號、規(guī)格是否正確無誤，零件是否缺少。②檢查機械密封各元件是否有損壞，特別是動環(huán)和靜環(huán)的密封端面是否碰傷，如發(fā)現(xiàn)損壞時，需進行返修或更換新的零件。各密封元件需用汽油或煤油清洗干凈，保持各元件表面無灰塵、異物。③軸或軸套表面及密封腔內(nèi)壁、密封端蓋內(nèi)表面是否有毛刺、溝痕等。如發(fā)現(xiàn)毛刺、溝痕時應(yīng)修平、打光，并用汽油或煤油清洗，保持清潔，不許有灰塵雜物附在表面上。④不要用不干凈的布或棉紗布擦洗動環(huán)和靜環(huán)表面，應(yīng)使用干凈柔軟的紗布、脫脂棉之類的東西擦洗。⑤裝配過程中應(yīng)保持清潔，保證動環(huán)、靜環(huán)的密封端面不被劃傷、碰破，為了更于裝入，裝配時應(yīng)在軸或軸套表面、壓蓋與密封圈配合表面涂抹機油，以免啟動瞬間產(chǎn)生干摩擦。。</p><p> 一、水泵機械密封基礎(chǔ)知識1.離心泵機械密封的基礎(chǔ)概念機械密封是指由至少一對垂直旋轉(zhuǎn)軸線的端面在流體壓力和補償機構(gòu)彈力（或磁力）的作用下以及輔助密封的配合下保持貼合并相對滑動而構(gòu)成的防止流體泄露的裝置。補償環(huán)的輔助密封為金屬波紋管的稱為波紋管機械密封。2.機械密封的組成主要有以下四類部件。a.主要密封件：動環(huán)和靜環(huán)。b.輔助密封件：密封圈。c.壓緊件：彈簧、推環(huán)。d.傳動件：彈簧座及鍵或固定螺釘。二、機封工作應(yīng)注意問題1.安裝時注意事項a.要十分注意避免安裝中所產(chǎn)生的安裝偏差上緊壓蓋應(yīng)在聯(lián)軸器找正后進行，螺栓應(yīng)均勻上支，防止壓蓋端面偏斜，用塞尺檢查各點，其誤差不大于。檢查壓蓋與軸或軸套外徑的配合間隙，四周要均勻，用塞尺檢查各點允差不大于。WQ2155-410-80凱泉泵用機械密封。</p><div

機械密封常見的損壞形式主要有腐蝕損壞、熱損壞和機械損壞。其中腐蝕損壞危害性較大，由于機械密封特殊的結(jié)構(gòu)形式及工作環(huán)境和條件不同，腐蝕損壞的形態(tài)也多種多樣。一．金屬環(huán)腐蝕1，表面均勻腐蝕。如果金屬環(huán)表面接觸腐蝕介質(zhì)，而金屬本身又不耐腐蝕，就會產(chǎn)生表面腐蝕，其現(xiàn)象是泄漏、早期磨損、破壞、發(fā)聲等。金屬表面均勻腐蝕有成膜和無膜兩種形態(tài)，無膜的金屬腐蝕很危險，腐蝕過程以一定的速度進行，這主要是選材錯誤造成的。成膜的腐蝕，其鈍化膜通常具有保護作用的特性，但金屬密封環(huán)所用的材料，如不銹鋼、鈷、鉻合金等其表面的鈍化膜在端面磨擦中破壞，在缺氧條件下新膜很難生成，使電偶腐蝕加劇。2，應(yīng)力腐蝕破裂。金屬在腐蝕和拉應(yīng)力的同時作用下，首先在薄弱區(qū)產(chǎn)生裂縫，進而向縱深發(fā)展，產(chǎn)生破裂，稱為應(yīng)力腐蝕破裂，選用堆焊硬質(zhì)合金及鑄鐵、碳化鎢、碳化鈦等密封環(huán)，容易出現(xiàn)應(yīng)力腐蝕破裂。密封環(huán)裂紋一般是徑向發(fā)散型的，可以是一條或多條。這些裂縫溝通了整個密封端面，加速了端面的磨損，使泄漏量增加。二．非金屬環(huán)腐蝕1，石墨環(huán)腐蝕。用樹脂浸漬的不透性石墨環(huán)，它的腐蝕有三個原因：一是當端面過熱，溫度大于180度時，浸漬的樹脂要折離石墨環(huán)。ZQ2850-4凱泉泵用機械密封。韶關(guān)凱泉泵用機械密封KQWH80-160A</p><p

是否影響機械密封的正常工作狀態(tài)。⑤檢查固定端蓋的螺釘是否松動，而引起密封端蓋的偏斜。⑥檢查泵的軸向竄動和徑向振動是否超過使用的技術(shù)要求。⑦若是裝軸套的情況，檢查軸套與軸之間的密封是否損壞，位置是否正確。⑧檢查密封體內(nèi)有無密封液循環(huán)，機械密封是否處于干摩擦狀態(tài)。機械密封件的選型方法和使用要求機械密封件屬于精密、結(jié)構(gòu)較為復(fù)雜的機械基礎(chǔ)元件之一，是各種泵類、反應(yīng)合成釜、透平壓縮機、潛水電機等設(shè)備的關(guān)鍵部件。其密封性能和使用壽命取決于許多因素，如選型、機器的精度、正確的安裝使用等。一、選型方法機械密封按工作條件和介質(zhì)性質(zhì)的不同，有耐高溫、耐低溫機械密封，耐高壓、耐腐蝕機械密封，耐顆粒介質(zhì)機械密封和適應(yīng)易汽化的輕質(zhì)烴介質(zhì)的機械密封等，應(yīng)根據(jù)不同的用處選取不同結(jié)構(gòu)型式和材料的機械密封。選型的主要參數(shù)有：密封腔體壓力(MPa)、流體溫度(℃)、工作速度(m/s)、流體的特性以及安裝密封的有效空間等。選型的基本原則為：1.根據(jù)密封腔體壓力，確定密封結(jié)構(gòu)采用平衡型或非平衡型，單端面或雙端面等。2.根據(jù)工作速度，確定采用旋轉(zhuǎn)式或靜止式，流體動壓式或非接觸型。3.根據(jù)溫度及流體性質(zhì)，確定摩擦副和輔助密封材料。青島凱泉泵用機械密封KQWH40-200A</p><p
