style="text-indent:25px">軸流風(fēng)機(jī)葉輪損壞原因分析。自然原因：1、雷擊：遭受雷擊是葉片毀壞的主要原因之一。如果避雷系統(tǒng)工作不正常，當(dāng)雷擊擊中一個(gè)葉片時(shí)，電流將會(huì)直接傳遞給發(fā)電機(jī)。如果葉片有砂眼下雨時(shí)就會(huì)積水，在受到雷擊的時(shí)候這些水分會(huì)瞬間蒸發(fā)，產(chǎn)生的蒸汽壓力會(huì)使葉片或裂開，這對(duì)機(jī)組來說是災(zāi)難性的、致命的。我們雖然無法控制雷擊這種自然現(xiàn)象，但是如果經(jīng)常檢查葉片防雷系統(tǒng)，修復(fù)有問題的避雷系統(tǒng)，將葉尖的排水孔里的雜質(zhì)清理干凈，就能較大限度的保護(hù)葉片，減少葉片遭受雷擊。2、空氣中的顆粒：由于葉片轉(zhuǎn)動(dòng)，它不可避免會(huì)與空氣中的顆粒產(chǎn)生摩擦和撞擊。在許多情況下,葉片的葉尖速度超過70m/S，在這個(gè)速度下，空氣中的顆粒會(huì)導(dǎo)致前緣磨損，前緣粘合會(huì)因此開裂。即使不是結(jié)構(gòu)性損壞，前緣磨損也會(huì)造成很大的發(fā)電損失。深圳大型風(fēng)機(jī)生產(chǎn)廠家</p></p><br
