但實際工程中水泵的整體設(shè)計優(yōu)化、設(shè)備配件的選用、各元件材質(zhì)的選擇都直接影響著水泵的密封性能。以水泵中的磁性分離器為例，該元件不但具有無法分離過濾非金屬顆粒、體積大、不易檢修等缺點，還可能由于磁性吸附水中的金屬性物質(zhì)，使這些物質(zhì)與非金屬材質(zhì)的旋動環(huán)或靜止環(huán)產(chǎn)生摩擦，導(dǎo)致元件的磨損，磨損生產(chǎn)的非金屬物質(zhì)又因不能被吸附過濾而進入系統(tǒng)使磨損加劇，長期運行必然會導(dǎo)致密封性能的下降。安裝環(huán)節(jié)造成的漏水現(xiàn)象安裝環(huán)節(jié)的施工不當(dāng)也可能造成密封損害。如在機械密封中起軸向定位作用的內(nèi)六角螺釘若安裝不緊，就會使密封發(fā)生軸向竄動，當(dāng)竄動量過大，壓縮彈簧不能使靜止環(huán)緊貼在旋動環(huán)上時，就會導(dǎo)致泄漏;環(huán)密封圈的軸端面及安裝靜環(huán)密封圈的密封壓蓋端面不夠光潔，可能使旋動環(huán)和靜止環(huán)在安裝時受損;而機械密封的彈簧壓縮量也是安裝的重點，一旦誤差應(yīng)>±2mm，太原神通博格曼機械密封106U，就可能因壓縮量過大導(dǎo)致端面比壓和摩擦熱量的增加，使端面的磨損和熱變形加劇，或因壓縮量過小造成靜止環(huán)端面的比壓不足，影響密封效果，太原神通博格曼機械密封106U。1）安裝過緊觀察機械密封的動靜環(huán)平面，若有嚴(yán)重?zé)?，平面發(fā)黑很深的痕跡，太原神通博格曼機械密封106U，密封橡膠變硬或失去彈性等現(xiàn)象，這都是由于安裝過緊造成的。福州神通博格曼機械密封。太原神通博格曼機械密封106U</p><div

3）按照靜止環(huán)裝于密封端面的內(nèi)側(cè)或者外側(cè)，分為內(nèi)裝式和外裝式。（4）彈簧設(shè)置在流體之內(nèi)為彈簧內(nèi)置式、反之為彈簧外置式（5）按照補償機構(gòu)彈簧的數(shù)量分為單彈簧式、多彈簧式。（6）按照彈性元件是否隨軸一起旋轉(zhuǎn)分為旋轉(zhuǎn)式、靜止式機械密封。（7）密封流體在密封端面間的泄漏方向如果與軸旋轉(zhuǎn)的離心方向一致則為外流式，反之為內(nèi)流式。（8）按照密封端面直接接觸與否分為接觸式機械密封，反之為非接觸式，其又可分為流體靜壓式及流體動壓式。（9）按照有否波紋管情況可分為非波紋管式波紋管式，后者又可分為金屬波紋管、四氟波紋管、橡膠波紋管等幾種。談到機械密封的安裝，很多人認為很簡單，其實不然，如果機封前期沒有裝配好，設(shè)備在使用中就會出現(xiàn)泄漏液體，損壞設(shè)備，甚至嚴(yán)重的會發(fā)生安全事故等；下面我們來著重講講化工泵機械密封在裝配及使用時一些注意事項問題：1、裝配前檢查事項：（1）必須查閱被安裝的機械密封是否適用你的使用工況范圍，當(dāng)輸送介質(zhì)溫度偏高,過低或含有雜質(zhì)顆粒,易燃,易爆,有毒時,必須采取相應(yīng)的阻封,沖洗,冷卻,過濾等措施。（2）應(yīng)仔細閱讀機械密封裝配圖,保證機械密封安裝尺寸及允差。（3）檢查有關(guān)的危險標(biāo)記,檢查安裝及連接尺寸。婁底神通博格曼機械密封113南寧神通博格曼機械密封。</p><div

同時原來溶于液體中的氣泡也將析出。這些汽跑隨液體流到葉輪內(nèi)壓力較高處汽泡重又凝結(jié)。在凝結(jié)過程中，由于體積急劇縮小，四周的液體以極大的速度沖向整個凝結(jié)空間，使泵內(nèi)造成沖擊振動和噪音。在壓力很大、頻率很高的液體質(zhì)點連續(xù)沖擊下，金屬表面逐漸因疲勞而破壞，這種破壞稱為剝蝕。同時溶于液體中的氧等活潑氣體也使金屬產(chǎn)生腐蝕。由于化學(xué)腐蝕與機械剝蝕的共同作用，加快了金屬損壞的速度，從而使葉輪受到破壞，這就是汽蝕破壞，這種由于液體的汽化和凝結(jié)而產(chǎn)生的沖擊現(xiàn)象就稱為氣蝕現(xiàn)象。消除泵進口氣蝕的措施有以下幾點：1.提高泵的氣蝕性能水平，滿足現(xiàn)場裝置的氣蝕性能的要求。2.泵應(yīng)當(dāng)在低于允許吸液高度下操作，以保證整個裝置安全可靠的運轉(zhuǎn)。3.采用抗氣蝕材料制造葉輪，如：2Cr13、稀土合金鑄鐵、高鎳鉻合金材料等，比普通鑄鐵的抗氣蝕能力要好得多。結(jié)語在分析泵用機械密封泄漏時，不僅要考慮機械密封的內(nèi)因，而且要考慮機械密封的外因。在實際工作中要注意以下幾個問題：1.使用正規(guī)廠家生產(chǎn)的泵，因為正規(guī)廠家生產(chǎn)的泵完全按照泵設(shè)計標(biāo)準(zhǔn)來制造的，在使用材料上不會偷工減料，有一定的保質(zhì)期。2.維修工應(yīng)增加對機械密封輔助系統(tǒng)的重要作用和認識。</p><p> 2）雙端面機械密封：有兩對密封端面組成的機械密封。當(dāng)介質(zhì)本身潤滑性差、有毒、易燃、易爆、易發(fā)揮以及對泄漏量有嚴(yán)格要求時。兩端面之間引入高于介質(zhì)壓力的密封冷卻液體，進行密封和冷卻。有可能實現(xiàn)介質(zhì)的“零泄漏”。又分為軸向和徑向雙端面。2、安平衡方式分：平衡式和非平衡式機械密封。1）平衡式機械密封：能使介質(zhì)作用在密封端面上的壓力卸荷的。安卸荷程度不同分為部分平衡式（部分卸荷）和過平衡式（全部卸荷）。它能降低端面上的摩擦和磨損，減少摩擦熱，承載能力大，但結(jié)構(gòu)較復(fù)雜，一般需要在軸或軸套上加工出一個臺階，成本較高。2）非平衡式機械密封：不能使介質(zhì)作用在密封端面上的壓力卸荷的。結(jié)構(gòu)簡單，介質(zhì)壓力小于***使用。3、按彈簧的布置形式分：彈簧內(nèi)置式機械密封和彈簧外置式機械密封。1）彈簧內(nèi)置式機械密封：彈簧至于介質(zhì)中與介質(zhì)接觸的。易受腐蝕，易被介質(zhì)中的雜物堵塞，如果彈簧隨軸旋轉(zhuǎn)，不宜在高粘度介質(zhì)中使用。2）彈簧外置式機械密封：彈簧未至于介質(zhì)中不與介質(zhì)接觸的。使用在高腐蝕、高粘度和易結(jié)晶介質(zhì)的設(shè)備上。4、按彈簧的數(shù)量分：單彈簧式機械密封和多彈簧式機械密封。1）彈性元件（密封補償器）中，只有一個彈簧的。GY神通博格曼機械密封。</p><div

彈簧、動環(huán)座等輔助件采用316或316L的材料。機封的時用壽命應(yīng)保證在8000小時。具體選用我們的結(jié)構(gòu)形式：OTH-7104系列、OTH-7108系列、OTH-7410系列、OTH-7422系列、OTH-7633系列、OTH-7806、OTH-7303系列，如果漿液的濃度不大可以選用OTH-7303,如果工況比較惡劣可以選用雙端面的結(jié)構(gòu):OTH-7401D系列。3、吸收塔系統(tǒng)吸收塔主要以攪拌器為主，多數(shù)電廠攪拌器以德國EKATO為主，選用我們的機械密封結(jié)構(gòu)以O(shè)TH-7638系列、OTH-7618系列為主，當(dāng)然我們看到多數(shù)的攪拌器機械密封有的帶軸承和外沖洗水，我們的型號稍加改動即可。綜上所述，電廠用泵的機械密封主要考慮兩個問題：(1)介質(zhì)的濃度對機械密封失效的影響，我們在結(jié)構(gòu)設(shè)計上多采用靜止型、彈簧外置、集裝式、外沖洗水結(jié)構(gòu)。(2)泵的汽蝕對機械密封的影響，我們從材質(zhì)和加工工藝上要求，我們的材質(zhì)一般選用304、316，對于主循環(huán)泵的機械密封要求不低于316L，保證了機械密封的使用壽命。廣州神通博格曼機械密封。太原神通博格曼機械密封106U</p><p

機組正常運行時凝結(jié)水泵處于負壓環(huán)境運行，若凝結(jié)水泵需要隔離檢修或入口濾網(wǎng)需要清理時，一旦凝結(jié)水泵入口門隔離不嚴(yán)或操作順序不當(dāng)則會有造成機組漏真空風(fēng)險。因此凝結(jié)水泵隔離恢復(fù)時應(yīng)嚴(yán)格按照操作順序，每一步操作都要觀察機組運行參數(shù)變化。2001年7月某電廠曾發(fā)生一起因凝泵檢修而導(dǎo)致機組掉真空跳機事件。2001年7月4日某電廠發(fā)生了一起因凝結(jié)水泵檢修而引起機組跳閘和一臺給水泵損壞的事故。當(dāng)時2號機運行，因發(fā)現(xiàn)凝結(jié)水泵出力不足，負荷帶不起來，于是聯(lián)系檢修。檢修人員辦票清理B凝結(jié)水泵入口濾網(wǎng)。約半小時后，檢修人員將B凝結(jié)水泵入口濾網(wǎng)打開。這時運行人員發(fā)現(xiàn)機組真空急劇下降，A凝結(jié)水泵電流劇烈波動，除氧器水位下降，凝汽器水位上升。運行人員立即啟動備用射水泵以維持真空，并降負荷。約2min后真空降至kPa，但低真空保護沒有動作。此時運行人員意識到可能是凝結(jié)水泵檢修引起的，立即去緊B凝結(jié)水泵入口手動門并終止檢修工作，但效果不明顯，除氧器水位繼續(xù)下降，于是繼續(xù)大幅降負荷。約7min后，A給水泵電流開始波動，A給水泵汽蝕。4min后，停A給水泵，啟動B給水泵，B給水泵仍處于輕微汽蝕狀態(tài)中。此時運行人員意識到了關(guān)鍵所在。太原神通博格曼機械密封106U</p><p
