機(jī)組正常運(yùn)行時(shí)凝結(jié)水泵處于負(fù)壓環(huán)境運(yùn)行，若凝結(jié)水泵需要隔離檢修或入口濾網(wǎng)需要清理時(shí)，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(huì)有造成機(jī)組漏真空風(fēng)險(xiǎn)。因此凝結(jié)水泵隔離恢復(fù)時(shí)應(yīng)嚴(yán)格按照操作順序，每一步操作都要觀察機(jī)組運(yùn)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(jī)組掉真空跳機(jī)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(jī)組跳閘和一臺(tái)給水泵損壞的事故。當(dāng)時(shí)2號(hào)機(jī)運(yùn)行，因發(fā)現(xiàn)凝結(jié)水泵出力不足，負(fù)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(shí)后，檢修人員將B凝結(jié)水泵入口濾網(wǎng)打開。這時(shí)運(yùn)行人員發(fā)現(xiàn)機(jī)組真空急劇下降，A凝結(jié)水泵電流劇烈波動(dòng)，除氧器水位下降，凝汽器水位上升。運(yùn)行人員立即啟動(dòng)備用射水泵以維持真空，并降負(fù)荷。約2min后真空降至kPa，但低真空保護(hù)沒有動(dòng)作。此時(shí)運(yùn)行人員意識(shí)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(dòng)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(fù)荷。約7min后，A給水泵電流開始波動(dòng)，A給水泵汽蝕。4min后，停A給水泵，啟動(dòng)B給水泵，B給水泵仍處于輕微汽蝕狀態(tài)中。此時(shí)運(yùn)行人員意識(shí)到了關(guān)鍵所在。韶關(guān)神通博格曼機(jī)械密封113湘潭神通博格曼機(jī)械密封。</p><div

但實(shí)際工程中水泵的整體設(shè)計(jì)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(diǎn)，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(dòng)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(jìn)入系統(tǒng)使磨損加劇，長期運(yùn)行必然會(huì)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(jī)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(huì)使密封發(fā)生軸向竄動(dòng)，當(dāng)竄動(dòng)量過大，壓縮彈簧不能使靜止環(huán)緊貼在旋動(dòng)環(huán)上時(shí)，就會(huì)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(dòng)環(huán)和靜止環(huán)在安裝時(shí)受損;而機(jī)械密封的彈簧壓縮量也是安裝的重點(diǎn)，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(jī)械密封的動(dòng)靜環(huán)平面，若有嚴(yán)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> 所以也要根據(jù)不同的工作溫度選用不同種類的浸漬石墨。一般浸巴氏合金石墨適用溫度范圍小于150℃，浸樹脂石墨適用溫度范圍為170~200℃，浸銅、鋁、鉛的石墨可在小于400℃的工作條件下使用。動(dòng)環(huán)組件應(yīng)盡可能選用膨脹系數(shù)相近的材料，以防止高溫下動(dòng)環(huán)和動(dòng)環(huán)座的連接松動(dòng)。3、選擇金屬波紋管機(jī)械密封。金屬波紋管密封近年來在高溫密封中使用很多，并且取得了很好的效果。在該種機(jī)封中，金屬波紋管取代了普通機(jī)封中的彈簧，省去了動(dòng)環(huán)輔助密封圈，不需要克服動(dòng)環(huán)補(bǔ)償時(shí)與轉(zhuǎn)軸的摩擦和磨損，因此在高溫下使用，一般都能取得不錯(cuò)的效果。二、低溫下的機(jī)械密封在煉油化工裝置中，低溫輸送的介質(zhì)一般都具有豁度小、潤滑性差、容易氣化的特點(diǎn)，而且介質(zhì)在氣化時(shí)大量吸熱，使周圍溫度急劇下降，造成空氣中水氣的凝結(jié)，導(dǎo)致端面及其周圍結(jié)冰，使端面貼合不嚴(yán)引起泄漏。同時(shí)，因潤滑性差，端面摩擦產(chǎn)生的熱量較多，若不能及時(shí)轉(zhuǎn)移，必然會(huì)加劇端面處的氣化，造成惡性循環(huán)，加速密封面的早期失效。另外，低溫密封的輔助密封圈在低溫下發(fā)硬失彈也容易導(dǎo)致泄漏。對低溫密封，除了選擇合適的輔助密封圈材質(zhì)外，還要注意以下幾點(diǎn)：1、改進(jìn)密封結(jié)構(gòu)及正確選擇摩擦副材料。實(shí)踐證明。108神通博格曼機(jī)械密封。</p><div

硬對硬摩擦副的運(yùn)轉(zhuǎn)壽命要比硬對石墨摩擦副的長,因?yàn)楣腆w顆粒會(huì)嵌入石墨密封環(huán)的密封面內(nèi)。對策:在固體顆粒容易進(jìn)入的位置應(yīng)選用碳化鎢對碳化鎢摩擦副的機(jī)械密封。三、機(jī)械密封周期性滲漏防爆自吸泵轉(zhuǎn)子軸向竄動(dòng)量大,輔助密封與軸的過盈量大,動(dòng)環(huán)不能在軸上靈活移動(dòng)。在泵翻轉(zhuǎn),動(dòng)、靜環(huán)磨損后,得不到補(bǔ)償位移。對策:在裝配機(jī)械密封時(shí),軸的軸向竄動(dòng)量應(yīng)小于(把動(dòng)環(huán)壓向彈簧能自由地彈回來)。四、密封面潤滑油量不足引起干摩擦或拉毛密封端面對策:油室腔內(nèi)潤滑油面高度應(yīng)加到高于動(dòng)、靜環(huán)密封面。五、轉(zhuǎn)子周期性振動(dòng)。原因是定子與上、下端蓋未對中或葉輪和主軸不平衡,汽蝕或軸承損壞(磨損),這種情況會(huì)縮短密封壽命和產(chǎn)生滲漏對策:可根據(jù)維修標(biāo)準(zhǔn)來糾正上述問題。六、因其他問題引起的機(jī)械密封滲漏機(jī)械密封中還存在設(shè)計(jì)、選擇、安裝等不夠合理的地方(1)彈簧壓縮量一定要按規(guī)定進(jìn)行,不允許有過大或過小的現(xiàn)象,誤差±2mm,壓縮量過大增加端面比壓,摩擦熱量過多,潤滑油泵造成密封面熱變形和加速端面磨損,壓縮量過小動(dòng)靜環(huán)端面比壓不足,則不能密封。(2)安裝動(dòng)環(huán)密封圈的軸(或軸套)端面及安裝靜環(huán)密封圈的密封壓蓋(或殼體)的端面應(yīng)倒角并修光,以免裝配時(shí)碰傷動(dòng)靜環(huán)密封圈。南寧神通博格曼機(jī)械密封。韶關(guān)神通博格曼機(jī)械密封113</p><p style="text-indent:25px">遼陽神通博格曼機(jī)械密封。韶關(guān)神通博格曼機(jī)械密封113</p><p> 端面比壓要合適，過大，將使機(jī)械密封摩擦面發(fā)熱，加速端面磨損，增加摩擦功率；過小，容易漏泄。端面比壓是在機(jī)械密封設(shè)計(jì)時(shí)確定的，我們在組裝時(shí)只能靠測量機(jī)械密封緊力來確定。通常情況的測量方法使測量安裝好的靜環(huán)端面至壓蓋端面的垂直距離，在測量動(dòng)環(huán)端面至壓蓋端面的垂直距離，兩者的差極為機(jī)械密封的緊力。4、測量補(bǔ)償彈簧的長度是否發(fā)生變化。彈簧性能的發(fā)生變化將會(huì)直接影響機(jī)械密封端面比壓。一般情況下彈簧在長時(shí)間運(yùn)行后長度會(huì)縮短，補(bǔ)償彈簧在動(dòng)環(huán)上的機(jī)械密封還會(huì)因?yàn)殡x心力的原因而變形。5、測量靜環(huán)防轉(zhuǎn)銷子的長度及銷孔深度，防止銷子過長靜環(huán)不能組裝到位。這種情況出現(xiàn)會(huì)損壞機(jī)械密封。二．多級離心泵機(jī)械密封的組裝經(jīng)過清掃檢查、技術(shù)尺寸校核后的機(jī)械密封即可回裝，在這個(gè)過程中要注意以下幾點(diǎn)：1、組裝時(shí)所有密封圈因該涂以肥皂水等潤滑劑，這樣可以避免組裝過程中損壞膠圈。動(dòng)靜環(huán)的密封面之間涂以潤滑脂，防止動(dòng)靜環(huán)密封面在水泵開車前磨損。2、浮動(dòng)環(huán)組裝時(shí)，一定要小心不要碰倒浮動(dòng)環(huán)彈簧，以免彈簧碰倒后影響浮動(dòng)環(huán)的浮動(dòng)性能。浮動(dòng)環(huán)組裝后，可以輕輕按浮動(dòng)環(huán)，以確定是否就有良好的浮動(dòng)性能。3、安裝密封時(shí)應(yīng)輕拿輕放，防止損壞密封件。韶關(guān)神通博格曼機(jī)械密封113</p></p><br
