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)，廊坊神通博格曼機械密封169。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)腐蝕與機械剝蝕的共同作用，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，廊坊神通博格曼機械密封169，以保證整個裝置安全可靠的運轉(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。結(jié)語在分析泵用機械密封泄漏時，不僅要考慮機械密封的內(nèi)因，而且要考慮機械密封的外因。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)計標準來制造的，在使用材料上不會偷工減料，廊坊神通博格曼機械密封169，有一定的保質(zhì)期。2.維修工應(yīng)增加對機械密封輔助系統(tǒng)的重要作用和認識。江蘇神通博格曼機械密封。廊坊神通博格曼機械密封169</p><div

二、機械密封漏水的防止措施設(shè)計過程中應(yīng)注意的問題應(yīng)根據(jù)不同水泵的工作特點選擇不同的機械密封類型，在仔細分析材質(zhì)、使用壽命等特點的基礎(chǔ)上推薦各密封元件，并重點參考其耐高溫、耐腐蝕、抗疲勞、抗振等方面的性能。雖然不同型號的機械密封在設(shè)計上存在較大的差異，但設(shè)計的重點始終應(yīng)體現(xiàn)在旋動環(huán)與靜止環(huán)間、軸套與旋動環(huán)間、靜止環(huán)與環(huán)座間、軸套與軸間以及密封端蓋與水泵泵體間等部位的密封，特別是**個部位的設(shè)計質(zhì)量是防止?jié)B漏的關(guān)鍵。使用過程中應(yīng)注意的問題安裝中防止?jié)B漏的對策應(yīng)切實提高安裝工程的質(zhì)量意識，嚴格執(zhí)行安裝、檢修的制度化和標準化。以密封圈的松緊度為例，旋動環(huán)密封圈過松會影響密封效果，但過緊也可能加劇其與軸套間的磨損，并易使旋動環(huán)出現(xiàn)疲勞和變形;而靜止環(huán)雖然相對應(yīng)更緊一些，但過緊也會導(dǎo)致變形或出現(xiàn)脆裂，因此必須依照安裝指導(dǎo)書測量和調(diào)整，保證其壓縮量符合要求。機械密封使用中滲漏的預(yù)防和處理日常機械密封的管路系統(tǒng)檢查與使用，是機械密封正常運行的保障，因此應(yīng)將設(shè)備管理的責(zé)任落實到人，制定嚴格的檢修維護制度并予以落實。檢查所有與機械密封運行有關(guān)的閥門，保證安監(jiān)儀表完好。</p><p>

在靜環(huán)表面開圓弧形凹槽可形成流體動力密封，增加流體膜承載能力，改善端面潤滑條件，有效延長機封工作壽命。在端面配對方面，碳化鎢一M106K石墨組對（即動、靜環(huán)材料）一般要優(yōu)于其他材料，因為其潤滑性好，摩擦系數(shù)低，導(dǎo)熱性也比較好。2、選擇合適的端面比壓。低溫密封由于端面潤滑性差，容易發(fā)生氣化、結(jié)冰，所以在保證密封可靠的前提下，端面比壓可適當(dāng)減小。一般機械密封比壓值推薦為，對低溫密封可取其下限。對金屬波紋管機械密封，由于動環(huán)沒有軸向摩擦，端面比壓甚至可以低于下限。3、工藝上采取相應(yīng)措施。如盡量減少介質(zhì)的含水量；保持密封腔壓力的相對穩(wěn)定；盡可能配備沖洗冷卻裝置；在設(shè)備啟動前，對機封部位進行適當(dāng)預(yù)熱等。三、高速下的機械密封當(dāng)轉(zhuǎn)速超過3000r/min或者摩擦副的線速度超過25m/s時，一般可視為高速密封。在高速條件下，摩擦端面由于線速度很大，摩擦產(chǎn)生的熱量也多，此時端面液膜不容易形成，磨損加劇。高速還容易引起旋轉(zhuǎn)環(huán)的振動，并受到較大的離心力作用，不利于端面間液膜的形成和維持。所以在高速情況下，為了減小離心力和振動的影響，應(yīng)盡量減少轉(zhuǎn)動部件，采用彈簧靜止式結(jié)構(gòu)。也可以加強對摩擦副端面的冷卻和潤滑。廊坊神通博格曼機械密封169</p><p
