泵用機械密封按結(jié)構(gòu)分類的基本形式有單端面機械密封、雙端面機械密封和串聯(lián)機械密封。由一對密封端面組成的為單端面機械密封；由兩對密封端面組成的為雙端面機械密封；由兩套或兩套以E同向布置單端面機械密封組成的機械密封為串聯(lián)機械密封。下面主要分別說明兩種機械密封的結(jié)構(gòu)特點供了解單端面與雙端面機械密封的區(qū)別。1、單端面機械密封單端面機械密封結(jié)構(gòu)簡單，如圖單端面機械密封結(jié)構(gòu)圖所示、制造成本低廉，安裝、使用方便，一般用于油、水、有機溶劑及腐蝕性介質(zhì)。通常使用單端面密封的泵類產(chǎn)品有立式單級管道離心泵、臥式離心泵單端面機械密封結(jié)構(gòu)圖如下2、雙端面機械密封有壓雙重機械密封(雙端面機械密封)多數(shù)用于易燃、易爆，阜陽HB100-65-60BS柳州酸王泵用機械密封、有毒、含顆粒及潤滑性差的介質(zhì)，通常使用時需配備密封輔助系統(tǒng)，即在兩端面間的密封腔中通入隔離流體，從而改善機械密封的潤滑和冷卻條件，如圖雙端面機械密封結(jié)構(gòu)圖所示，阜陽HB100-65-60BS柳州酸王泵用機械密封，阜陽HB100-65-60BS柳州酸王泵用機械密封。雙端面機械密封結(jié)構(gòu)圖如下使用雙端面機械密封的泵類產(chǎn)品有：氟塑料離心泵或者IH不銹鋼化工泵等3、單端面與雙端面機械密封零件及相應(yīng)術(shù)語密封環(huán)：機械密封中其端面垂直于旋轉(zhuǎn)軸線相互貼合并相對滑動的兩個環(huán)形零件稱密封環(huán)。柳州酸王泵用機械密封HF65-250B。阜陽HB100-65-60BS柳州酸王泵用機械密封</p><div

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，以防止高溫下動環(huán)和動環(huán)座的連接松動。3、選擇金屬波紋管機械密封。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。在該種機封中，金屬波紋管取代了普通機封中的彈簧，省去了動環(huán)輔助密封圈，不需要克服動環(huán)補償時與轉(zhuǎn)軸的摩擦和磨損，因此在高溫下使用，一般都能取得不錯的效果。二、低溫下的機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，而且介質(zhì)在氣化時大量吸熱，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，使端面貼合不嚴引起泄漏。同時，因潤滑性差，端面摩擦產(chǎn)生的熱量較多，若不能及時轉(zhuǎn)移，必然會加劇端面處的氣化，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：1、改進密封結(jié)構(gòu)及正確選擇摩擦副材料。實踐證明。</p><p> 密封端面：密封環(huán)在工作時與另一個密封環(huán)相貼合的端面。該端面通常是研磨面。旋轉(zhuǎn)環(huán)(動環(huán))：隨軸做旋轉(zhuǎn)運動的密封環(huán)。靜止環(huán)(靜環(huán))：不隨軸做旋轉(zhuǎn)運動的密封環(huán)。補償環(huán)：具有軸向補償能力的密封環(huán)。非補償環(huán)：不具有軸向補償能力的密封環(huán)。補償環(huán)組件：軸向連接并定位彈性元件的零件。傳動座：用于與軸或軸套固定并直接帶動旋轉(zhuǎn)環(huán)的零件。傳動螺釘：用于傳遞扭矩的螺釘。緊定螺釘：用于把彈簧座、傳動座或其他零件固定于軸或軸套上的螺釘。卡環(huán)：對補償環(huán)起軸向限位作用的零件。防轉(zhuǎn)銷：用于防止相鄰兩個零件相對旋轉(zhuǎn)的銷釘。密封腔：指安裝密封部位旋轉(zhuǎn)軸與靜止殼體之間的環(huán)狀空間。密封腔體：包容密封腔的靜止殼體；彈性元件：彈簧或波紋管之類的具有彈性的零件。摩擦副：配對使用的一組密封環(huán)。濱海新區(qū)柳州酸王泵用機械密封。</p><div

機械密封是一個由一系列簡單設(shè)計元件組成的組合機構(gòu)，密封作用由兩個帶平面的主密封環(huán)完成，以防止泄漏。其中一個密封環(huán)與軸連在一起轉(zhuǎn)動，另一個密封環(huán)固定在殼體上。為了密封離心泵軸，靜密封環(huán)安裝在密封腔壓蓋上。在泵軸轉(zhuǎn)動期間，裝在軸上的密封環(huán)的密封面與對面的靜環(huán)密封面相摩擦。這兩個密封接觸面的接觸作用類似軸承，并且受到磨損。任何形式的系統(tǒng)泄漏都必須通過這個密封接觸面。作用在軸向的力使密封環(huán)始終保持摩擦接觸，其來源可以為機械的或者是液壓的，在很多設(shè)計中，取兩者之和。這種穩(wěn)定的接觸可以防止從摩擦面間泄漏或使泄漏量減到很小。其常見泄漏點如下，如圖所示，典型泄漏點包括：1.動靜環(huán)接觸端面這個是機械密封的主要密封面，是決定密封的摩擦、磨損和密封性能的關(guān)鍵，同時也決定了密封的工作壽命。據(jù)統(tǒng)計，大約有80%~90%的泄漏是由于摩擦面造成的。2.動環(huán)（補償環(huán)）輔助密封圈處這是輔助密封面，是決定密封的密封性和動環(huán)追隨性的關(guān)鍵。此處重要性僅次于1處。3.軸與軸套間此處為靜密封，需考慮材質(zhì)與介質(zhì)相容。4.密封件本身此處可能由于浸漬工藝等原因發(fā)生滲漏。5.靜環(huán)（非補償環(huán)）輔助密封圈處這是輔助密封面，是決定密封的密封性能的關(guān)鍵點之一。上海柳州酸王泵用機械密封。阜陽HB100-65-60BS柳州酸王泵用機械密封</p><p

被密封介質(zhì)在通過曲折迷宮的間隙時產(chǎn)生節(jié)流效應(yīng)而達到阻漏的目的。迷宮密封是離心式壓縮機級間和軸端基本的密封形式，根據(jù)結(jié)構(gòu)特點的不同，可分為平滑式、曲折式、階梯式及蜂窩式等四種類型。1、平滑式迷宮密封平滑式迷宮密封有整體和鑲片兩種結(jié)構(gòu)，它結(jié)構(gòu)簡單，便于制造，但密封效果較差。2、曲折式迷宮密封曲折式迷宮密封也分整體和鑲片兩種結(jié)構(gòu)，這種迷宮密封的結(jié)構(gòu)特點，是密封齒的伸出高度不一樣，而且高低齒相間排列，與之相配的軸表面，是特制的凹凸溝槽，這種高低齒與凹凸槽相配合的結(jié)構(gòu)，使平滑的密封間隙變成了曲折式，因此，增加了流動阻力，提高了密封效能。但只能用在有水平剖分面的缸體或隔板中，并且密封體也要作成水平剖分型。3、階梯式迷宮密封階梯式迷宮密封從結(jié)構(gòu)上分析它類似于平滑式迷宮密封，而密封效果卻與曲折式迷宮密封近似，常用于葉輪蓋板和平衡盤處。4、蜂窩式迷宮密封蜂窩式迷宮密封的密封齒片焊成蜂窩狀，以形成復(fù)雜形狀的膨脹室，它的密封性能優(yōu)于一般密封形式，適用于壓力差較大的場合，如離心式壓縮機的平衡盤密封。蜂窩式迷宮密封制造工藝復(fù)雜，密封片強度高，密封效果較好。阜陽HB100-65-60BS柳州酸王泵用機械密封</p></p><br
