機械密封用于各種類型的泵。機械密封是一種精度較高的密封裝置，對安裝和使用條件均有一定的要求。1、機械密封安裝使用的一般原則(1)弄清設(shè)備的情況，要了解設(shè)備轉(zhuǎn)軸的轉(zhuǎn)速、軸徑;設(shè)備制造精度及密封腔尺寸，設(shè)備本身的使用壽命以及設(shè)備在生產(chǎn)工藝中的地位等要做***均衡的考慮。(2)估算介質(zhì)壓力。泵的密封腔壓力一般不是泵的出口壓力，而是低于泵的出口壓力。(3)弄清密封介質(zhì)情況。要知道密封介質(zhì)的狀態(tài)，是氣態(tài)還是液態(tài)，介質(zhì)是否含顆粒及顆粒狀況;了解介質(zhì)的性質(zhì)、溫度，以便合理選型及采取必要的冷卻、沖洗、潤滑措施。2、機械密封安裝使用的技術(shù)要求(1)安裝機械密封部位的軸或軸套的徑向跳動公差：Ф10~50mmФ50~120mm,。軸或軸套的表面粗糙度應(yīng)符合技術(shù)要求，外徑尺寸公差為h6。(2)傳動軸的軸向竄動量不超過。(3)密封腔體端面對軸表面的跳動公差：軸或軸套外徑端面跳動公差:Ф10~50mm，Ф50~120mm,(4)軸或軸套的端面及密封腔體的端面要有倒角。軸徑≤Φ30mm時為3×10°，軸徑>Φ30mm時為4×10°。(5)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，應(yīng)采取相應(yīng)的阻封、沖洗、冷卻、過濾等措施。(6)對某些靠彈簧傳動的機械密封必須注意彈簧的旋向。唐山FBD神通博格曼機械密封J00神通博格曼機械密封。</p><div

機組正常運行時凝結(jié)水泵處于負(fù)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(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(fù)荷。約2min后真空降至kPa，但低真空保護(hù)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(fù)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。</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(jìn)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。宣城神通博格曼機械密封。</p><div

1、機械密封的定義：由至少一對垂直于旋轉(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)成的防止流體泄漏的裝置。機械密封又稱為“端面密封”。1、機械密封的組成：1、摩擦副（動環(huán)，靜環(huán)）2、補償元件（彈簧，波紋管）3、輔助密封圈（O形圈，四氟圈）4、傳動件/緊固件（緊定螺釘，螺栓，防轉(zhuǎn)銷）3、機械密封特點：4、機械密封的分類：：接觸式機械密封端面處不產(chǎn)生使兩端面間保持一定間隙的氣膜或液膜動壓力。非接觸式機械密封：非接觸式密封在端面處能產(chǎn)生使兩端面間保持一定間隙的氣膜或液膜動壓力。多彈簧機械密封單彈簧機械密封波紋管機械密封5、按使用的設(shè)備劃分：泵用機械密封，釜用機械密封，離心壓縮機用機械密封。5、機械密封布置方式：單端面機械密封、雙端面機械密封-面對背布置、雙端面機械密封-背靠背布置單端面機械密封雙端面機械密封-面對背布置雙端面機械密封-背靠背布置6、機械密封材料機械密封的摩擦副材料：?對機械密封摩擦副材料的要求：耐磨性，耐蝕性，耐熱及導(dǎo)熱性。?軟端面材料（API682）?石墨材料：浸樹脂石墨，浸銻石墨?硬端面材料(API682)?反映燒結(jié)SiC。煙臺神通博格曼機械密封。唐山FBD神通博格曼機械密封</p><p

端面比壓要合適，過大，將使機械密封摩擦面發(fā)熱，加速端面磨損，增加摩擦功率；過小，容易漏泄。端面比壓是在機械密封設(shè)計時確定的，我們在組裝時只能靠測量機械密封緊力來確定。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，在測量動環(huán)端面至壓蓋端面的垂直距離，兩者的差極為機械密封的緊力。4、測量補償彈簧的長度是否發(fā)生變化。彈簧性能的發(fā)生變化將會直接影響機械密封端面比壓。一般情況下彈簧在長時間運行后長度會縮短，補償彈簧在動環(huán)上的機械密封還會因為離心力的原因而變形。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)會損壞機械密封。二．多級離心泵機械密封的組裝經(jīng)過清掃檢查、技術(shù)尺寸校核后的機械密封即可回裝，在這個過程中要注意以下幾點：1、組裝時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。動靜環(huán)的密封面之間涂以潤滑脂，防止動靜環(huán)密封面在水泵開車前磨損。2、浮動環(huán)組裝時，一定要小心不要碰倒浮動環(huán)彈簧，以免彈簧碰倒后影響浮動環(huán)的浮動性能。浮動環(huán)組裝后，可以輕輕按浮動環(huán)，以確定是否就有良好的浮動性能。3、安裝密封時應(yīng)輕拿輕放，防止損壞密封件。唐山FBD神通博格曼機械密封</p></p><br
