2）機械密封處的泵軸撓度要小，只有滿足類似這樣的外因，再加上良好的機械密封自身性能，才能達到理想的密封效果。影響泵用機械密封的外部原因（一）泵軸的軸向竄量機械密封的密封面要有一定的比壓（～），從而達到密封的目的，兩端面的緊密緊密程度可以通過彈簧調(diào)節(jié)。為了保證這個比壓，要求泵軸不能有太大的竄量（≤），但在實際生產(chǎn)中，往往泵軸產(chǎn)生很大的竄量。對機械密封的使用非常不利的，婁底FBD神通博格曼機械密封，這種情況在我分廠表現(xiàn)在泵啟動過程中，由于不平衡軸向力的存在，使整個軸發(fā)生向吸入口的竄動，造成機械密封失去密封作用，常用的措施有：葉輪上開平衡孔，泵體上裝平衡管等。（二）泵軸的撓度偏大軸彎曲變形時橫截面形心沿與軸線垂直方向的線位移稱為撓度，機械密封要求兩個密封端面之間受力均勻。但由于泵產(chǎn)品設(shè)計的不合理，婁底FBD神通博格曼機械密封，在機械密封安裝處產(chǎn)生的撓度偏大，使密封處受力不均勻，從而失去密封效果。這種現(xiàn)象大多存在臥式多級離心泵中。（三）沒有輔助沖洗系統(tǒng)或輔助沖洗系統(tǒng)設(shè)計不合理機械密封的輔助沖洗系統(tǒng)是非常重要的，它可以有效的保護密封面，起到冷卻、潤滑、沖走雜物等作用。有時設(shè)計人員設(shè)計不合理，達不到密封效果；有的設(shè)計了輔助系統(tǒng)，婁底FBD神通博格曼機械密封，但由于沖洗液中有雜質(zhì)。濟南神通博格曼機械密封。婁底FBD神通博格曼機械密封</p><div

但泄漏點主要有五處：（1）軸套與軸間的密封；（2）動環(huán)與軸套間的密封；（3）動、靜環(huán)間密封；（4）對靜環(huán)與靜環(huán)座間的密封；（5）密封端蓋與泵體間的密封。一般來說，軸套外伸的軸間、密封端蓋與泵體間的泄漏比較容易發(fā)現(xiàn)和解決，但需細致觀察。其余的泄漏直觀上很難辯別和判斷，須在長期管理、維修實踐的基礎(chǔ)上，對泄漏癥狀進行觀察、分析、研判，才能得出正確結(jié)論。3、泄漏原因分析及判斷、安裝靜試時泄漏機械密封安裝調(diào)試好后，一般要進行靜試，觀察泄漏量。如泄漏量較小，多為動環(huán)或靜環(huán)密封圈存在問題；泄漏量較大時，則表明動、靜環(huán)摩擦副間存在問題。在初步觀察泄漏量、判斷泄漏部位的基礎(chǔ)上，再手動盤車觀察，若泄漏量無明顯變化則靜、動環(huán)密封圈有問題；如盤車時泄漏量有明顯變化則可斷定是動、靜環(huán)摩擦副存在問題；如泄漏介質(zhì)沿軸向噴射，則動環(huán)密封圈存在問題居多，泄漏介質(zhì)向四周噴射或從水冷卻孔中漏出，則多為靜環(huán)密封圈失效。此外，泄漏通道也可同時存在，但一般有主次區(qū)別，只要觀察細致，熟悉結(jié)構(gòu)，一定能正確判斷。水泵機械密封泄露的原因、試運轉(zhuǎn)時出現(xiàn)的泄漏泵用機械密封經(jīng)過靜試后，運轉(zhuǎn)時高速旋轉(zhuǎn)產(chǎn)生的離心力，會減少介質(zhì)的泄漏。因此。婁底FBD神通博格曼機械密封神通博格曼機械密封113。</p><div

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，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。1）安裝過緊觀察機械密封的動靜環(huán)平面，若有嚴重?zé)?，平面發(fā)黑很深的痕跡，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。</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。沈陽神通博格曼機械密封。</p><div
