沖洗液可以是熱水或蒸汽。九、機械密封典型失效原因分析（一）機械密封本身問題1、鑲裝不到位或不平整。2、載荷系數(shù)太大或端面比壓設計不合理。3、材質選用不當。4、密封面不平。5、密封面太寬或太窄。（二）輔助系統(tǒng)問題1、工況條件復雜，但沒有沖洗等輔助設施。2、沖洗管堵塞。3、冷卻管結垢。（三）介質及工作條件問題1、介質腐蝕性強。2、介質中有固體顆粒。3、設備抽空。4、密封面結晶。5、介質粘度太大。（四）泵的問題1、軸的加工精度不佳、串軸、跳動、安裝間隙過大。2、泵開啟后振動太大。3、壓蓋墊環(huán)不佳。4、密封箱不平。5、機械密封安裝沒有達到應有的壓縮量。十、常見的滲漏現(xiàn)象機械密封滲漏的比例占全部維修泵的50%以上，機械密封的運行好壞直接影響到水泵的正常運行，現(xiàn)總結分析如下：1、周期性滲漏（1）泵轉子軸向竄動量大，輔助密封與軸的過盈量大，動環(huán)不能在軸上靈活移動。在泵翻轉，動、靜環(huán)磨損后，得不到補償位移。對策：在裝配機械密封時，軸的軸向竄動量應小于0．1mm，輔助密封與軸的過盈量應適中，在保證徑向密封的同時，動環(huán)裝配后保證能在軸上靈活移動（把動環(huán)壓向彈簧能自由地彈回來）。（2）密封面潤滑油量不足引起干摩擦或拉毛密封端面。鶴崗泵用機械密封阜陽橡膠波紋管機械密封件。</p><div

同時無壓雙重機械密封外側密封就能在維修前起到密封和容納泄漏液體的作用。對一些有毒、含顆粒介質(或腐蝕性相當厲害的介質)，一般可考慮以下方法：(1)采用合適的環(huán)境控制措施，如外沖洗+帶旋風分離器的管路沖洗系統(tǒng)。(2)采用有壓雙重機械密封。有壓雙重機械密封隔離液的壓力高于介質壓力，因而泵送介質不會進入密封腔。有壓雙重機械密封內(nèi)側密封起到阻止隔離液進入泵腔的作用。因此當輸送諸如粘性、磨蝕性及高溫介質時，有壓雙重機械密封內(nèi)側密封由于沒有暴露在介質中，因此可以不用昂貴的合金制作。有壓雙重機械密封外側密封僅僅起到不使隔離液漏入大氣的作用。3、平衡型機械密封和非平衡型機械密封機械密封密封腔中的壓力作用在動環(huán)上形成了閉合力，端面間的液膜形成開啟力。載荷系數(shù)K>1，密封為非平衡型機械密封。一般非平衡型機械密封只能用于低壓。當壓力大于一定的限度，密封面間的液膜就會被擠出。在喪失液膜潤滑及高負荷的作用下，機械密封的密封端面會很快損壞。非平衡型機械密封不能平衡液體對端面的作用，端面比壓隨流體壓力的上升而上升。載荷系數(shù)K<1，密封為平衡型機械密封。</p><p> 應用場合：應用于雙端面承壓密封（雙重），高蒸汽壓流體，輕質烴，危險/有毒流體，傳熱流體，臟、腐蝕和聚合流體。PLAN53C（帶增壓罐的雙端面密封）方案描述：由外部管道系統(tǒng)為加壓雙斷面密封裝置的外側密封提供隔離液，從密封腔到活塞蓄壓器的參比管線提供壓力給循環(huán)系統(tǒng)，流動由內(nèi)部輸液環(huán)來保持，循環(huán)系統(tǒng)中的熱量由空氣空氣冷卻或水冷卻熱交換器除去。采用原因：分離工藝流體，零流程排放，比53A方案壓力高。應用場合：應用于雙端面承壓密封（雙重），高蒸汽壓體。PLAN53A、B、C比較介紹Plan53機械密封沖洗系統(tǒng)由具有隔離液的串聯(lián)密封或雙端面密封組成，密封罐在有一定壓力（一般高于被密封介質壓力的10%）的條件下工作，其壓力的來源以及隔離液的冷卻方式不同。Plan53機械密封沖洗系統(tǒng)有Plan53A、Plan53B和Plan53C三種。Plan53A外接壓力源、內(nèi)置冷卻盤管、并設有壓力、液位等報警指示裝置；Plan53B的壓力由內(nèi)置充氣的氣囊提供，采用翅片管直接散熱或水冷器管冷卻隔離液；Plan53C的壓力由增壓泵提供，增壓泵與冷卻器設計為一體，也可與冷卻器分體。對于Plan53來說，如果采用雙端面密封方式，即面對面的方式，兩個密封面的沖洗、冷卻均由隔離液來提供。合肥YM109機械密封件。</p><div

以及機械密封的平衡程度，還有密封端面液膜的閃蒸等都是造成端面打開而使固體顆粒進入的主要原因。c）機械密封的平衡程度β也影響著密封的磨損。一般情況下，平衡程度β=75%左右適宜。β<75%，磨損量雖然降低，但泄漏增加，密封面打開的可能性增大。對于高負荷（高PV值）的機械密封，由于端面摩擦熱較大，β一般取65%～70%為宜，對低沸點的烴類介質等，由于溫度對介質氣化較敏感，為減少摩擦熱的影響，β取80%～85%為好。7.因安裝、運轉或設備本身所產(chǎn)生的誤差而造成機械密封泄漏a）由于安裝不良，造成機械密封泄漏。主要表現(xiàn)在以下幾方面：1）動、靜環(huán)接觸表面不平，安裝時碰傷、損壞；2）動、靜環(huán)密封圈尺寸有誤、損壞或未被壓緊；3）動、靜環(huán)表面有異物；4）動、靜環(huán)V型密封圈方向裝反，或安裝時反邊；5）軸套處泄漏，密封圈未裝或壓緊力不夠；6）彈簧力不均勻，單彈簧不垂直，多彈簧長短不一；7）密封腔端面與軸垂直度不夠；8）軸套上密封圈活動處有腐蝕點。b）設備在運轉中，機械密封發(fā)生泄漏的原因主要有：1）泵葉輪軸向竄動量超過標準，轉軸發(fā)生周期性振動及工藝操作不穩(wěn)定，密封腔內(nèi)壓力經(jīng)常變化等均會導致密封周期性泄漏。南通橡膠波紋管機械密封件。漳州常規(guī)機械密封</p><p
