同時原來溶于液體中的氣泡也將析出。這些汽跑隨液體流到葉輪內(nèi)壓力較高處汽泡重又凝結(jié)。在凝結(jié)過程中，由于體積急劇縮小，四周的液體以極大的速度沖向整個凝結(jié)空間，使泵內(nèi)造成沖擊振動和噪音。在壓力很大、頻率很高的液體質(zhì)點連續(xù)沖擊下，金屬表面逐漸因疲勞而破壞，這種破壞稱為剝蝕。同時溶于液體中的氧等活潑氣體也使金屬產(chǎn)生腐蝕。由于化學(xué)腐蝕與機(jī)械剝蝕的共同作用(公眾號:泵管家)，加快了金屬損壞的速度，從而使葉輪受到破壞，這就是汽蝕破壞，這種由于液體的汽化和凝結(jié)而產(chǎn)生的沖擊現(xiàn)象就稱為氣蝕現(xiàn)象。消除泵進(jìn)口氣蝕的措施有以下幾點：1．提高泵的氣蝕性能水平，滿足現(xiàn)場裝置的氣蝕性能的要求。2．泵應(yīng)當(dāng)在低于允許吸液高度下操作，以保證整個裝置安全可靠的運(yùn)轉(zhuǎn)。3．采用抗氣蝕材料制造葉輪，如：2Cr13、稀土合金鑄鐵、高鎳鉻合金材料等，比普通鑄鐵的抗氣蝕能力要好得多。三、結(jié)語在分析泵用機(jī)械密封泄漏時，不僅要考慮機(jī)械密封的內(nèi)因，而且要考慮機(jī)械密封的外因。在實際工作中要注意以下幾個問題：1．使用正規(guī)廠家生產(chǎn)的泵，因為正規(guī)廠家生產(chǎn)的泵完全按照泵設(shè)計標(biāo)準(zhǔn)來制造的，在使用材料上不會偷工減料，有一定的保質(zhì)期。</p><p> 1.彈簧壓縮量越大密封效果越好？其實不然，彈簧壓縮量過大，可導(dǎo)致摩擦副急劇磨損，瞬間燒損；過度的壓縮使彈簧失去調(diào)節(jié)動環(huán)端面的能力，導(dǎo)致密封失效。2.動環(huán)密封圖越緊越好？其實動環(huán)密封圈過緊有害無益。一是加劇密封圈與軸套間的磨損，泄漏；二是增大了動環(huán)軸向調(diào)整、移動的阻力，在工況變化頻繁時無法適時進(jìn)行調(diào)整；三是彈簧過度疲勞易損壞；四是使動環(huán)密封圈變形，影響密封效果。3．靜環(huán)密封圈越緊越好？靜環(huán)密封圈基本處于靜止?fàn)顟B(tài)，相對較緊密封效果會好些，但過緊也是有害的。一是引起靜環(huán)密封因過度變形，影響密封效果；二是靜環(huán)材質(zhì)以石墨居多，一般較脆，過度受力極易引起碎裂；三是安裝、拆卸困難，極易損壞靜環(huán)。4．葉輪鎖母越緊越好？機(jī)械密封泄漏中，軸套與軸之間的泄漏（軸間泄漏）是比較常見的。一般認(rèn)為，軸間泄漏就是葉輪鎖母沒鎖緊，其實導(dǎo)致軸間泄漏的因素較多，如軸間墊失效，偏移，軸間內(nèi)有雜質(zhì)，軸與軸套配合處有較大的形位誤差，接觸面破壞，軸上各部件間有間隙，軸頭螺紋過長等都會導(dǎo)致軸間泄漏。鎖母鎖緊過度只會導(dǎo)致軸間墊過早失效，相反適度鎖緊鎖母，使軸間墊始終保持一定的壓縮彈性，在運(yùn)轉(zhuǎn)中鎖母會自動適時鎖緊。襄樊五二五機(jī)械密封LC550/700。</p><div

保證靜環(huán)斷面與端蓋中心線的垂直度，且將水泵機(jī)械密封靜環(huán)背部的防轉(zhuǎn)槽對準(zhǔn)防轉(zhuǎn)銷，但勿使其中互相接觸。6.水泵機(jī)械密封安裝過程中決不允許用工具直接敲打密封元件，需要敲打時，必須使用**工具進(jìn)行敲打，以防密封元件的損壞7.水泵機(jī)械密封組裝時所有密封圈應(yīng)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。8.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。9.更換水泵機(jī)械密封時應(yīng)輕拿輕放，防止損壞密封件，安裝時應(yīng)將密封及腔體擦洗干凈。10.緊固水泵機(jī)械密封壓蓋時緊固螺栓應(yīng)均勻受力，防止受力不均損壞機(jī)械密封。對于快裝式機(jī)械密封在整體組裝完畢后一定不要忘記將定位片徑向移動道遠(yuǎn)離軸的位置固定。三、注意因為機(jī)械密封所密封的介質(zhì)是不同的，涼水和熱水的溫度不同，密封的介質(zhì)是否具有腐蝕性，腔室內(nèi)壓力的不同，機(jī)械密封的設(shè)計就會不同，檢修工藝也會有所差別，水泵機(jī)械密封檢修過程中總結(jié)出一些經(jīng)驗：機(jī)械密封要組裝，清掃檢查莫忘記。先看兩環(huán)后看軸，傷痕裂紋不要漏。襄樊五二五機(jī)械密封IH-25D/200S/SS3。襄陽襄樊五二五機(jī)械密封IH-25D/200S/SS3</p><p
