液體就會(huì)沸騰汽化，產(chǎn)生大量氣泡。同時(shí)原來(lái)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(guò)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(gè)凝結(jié)空間，使泵內(nèi)造成沖擊振動(dòng)和噪音。在壓力很大、頻率很高的液體質(zhì)點(diǎn)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(shí)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，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(diǎn)：1．提高泵的氣蝕性能水平，滿足現(xiàn)場(chǎng)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(gè)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(yǔ)在分析泵用機(jī)械密封泄漏時(shí)，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(shí)際工作中要注意以下幾個(gè)問(wèn)題：1．使用正規(guī)廠家生產(chǎn)的泵，因?yàn)檎?guī)廠家生產(chǎn)的泵完全按照泵設(shè)計(jì)標(biāo)準(zhǔn)來(lái)制造的，在使用材料上不會(huì)偷工減料，有一定的保質(zhì)期。三門峽反應(yīng)釜用機(jī)械密封件。</p><div

三是安裝、拆卸困難，極易損壞靜環(huán)。誤區(qū)四：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(méi)鎖緊，其實(shí)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(guò)長(zhǎng)等都會(huì)導(dǎo)致軸間泄漏。鎖母鎖緊過(guò)度只會(huì)導(dǎo)致軸間墊過(guò)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(huì)自動(dòng)適時(shí)鎖緊，使軸間始終處于良好的密封狀態(tài)。誤區(qū)五：新的比舊的好？！相對(duì)而言，使用新機(jī)械密封的效果好于舊的，但新機(jī)械密封的質(zhì)量或材質(zhì)選擇不當(dāng)時(shí)，配合尺寸誤差較大會(huì)影響密封效果；在聚合性和滲透性介質(zhì)中，靜環(huán)如無(wú)過(guò)度磨損，還是不更換為好。因?yàn)殪o環(huán)在靜環(huán)座中長(zhǎng)時(shí)間處于靜止?fàn)顟B(tài)，使聚合物和雜質(zhì)沉積為一體，起到了較好的密封作用。誤區(qū)六：拆修總比不拆好？！一旦出現(xiàn)機(jī)械密封泄漏便急于拆修，其實(shí)，有時(shí)密封并沒(méi)有損壞，只需調(diào)整工況或適當(dāng)調(diào)整密封就可消除泄漏。這樣既避免浪費(fèi)又可以驗(yàn)證自己的故障判斷能力，積累維修經(jīng)驗(yàn)提高檢修質(zhì)量。威海M481釜用機(jī)械密封件。忻州M481釜用機(jī)械密封件設(shè)計(jì)</p><p
