諾冠NORGREN空氣過(guò)濾器的發(fā)展歷程
點(diǎn)擊次數(shù)：1309 發(fā)布時(shí)間：2012-4-19
諾冠NORGREN空氣過(guò)濾器的發(fā)展歷程的迅速發(fā)展是與軍事工業(yè)和電子工業(yè)的發(fā)展緊密相關(guān)的,。玻璃纖維過(guò)濾介質(zhì)用于空氣過(guò)濾于1940年10月在美國(guó)取得,。50年代,美國(guó)對(duì)玻璃纖維過(guò)濾紙的生產(chǎn)工藝進(jìn)行了深入的研究,使空氣過(guò)濾器得到了改善和發(fā)展。60年代,HEPA過(guò)濾器問(wèn)世;70年代,采用微細(xì)玻璃纖維過(guò)濾紙作為過(guò)濾介質(zhì)的HEPA過(guò)濾器,對(duì)013微米粒徑的粒子過(guò)濾效率高達(dá)99.9998%,。八十年代以來(lái),隨著新的測(cè)試方法的出現(xiàn),、使用評(píng)價(jià)的提高及對(duì)過(guò)濾性能要求的提高,發(fā)現(xiàn)HEPA過(guò)濾器存在著嚴(yán)重的問(wèn)題,于是又產(chǎn)生了性能更高的ULPA過(guò)濾器。目前,各國(guó)仍在努力研究,估計(jì)不久就會(huì)出現(xiàn)更*空氣過(guò)濾器,。
編輯本段顯著進(jìn)展
諾冠NORGREN空氣過(guò)濾器的發(fā)展歷程 其中zui重要的是分隔板的去除,即無(wú)隔板過(guò)濾器的發(fā)展,。無(wú)隔板過(guò)濾器不僅消除了分隔板損壞過(guò)濾介質(zhì)的危險(xiǎn),而且有效地增加了過(guò)濾面積,提高了過(guò)濾效率,并降低了氣流阻力,從而減少了能量消耗。此外,空氣過(guò)濾器在耐高溫,、耐腐蝕以及防水,、防菌等方面也取很大的進(jìn)展,滿(mǎn)足了一些特殊的需求。
空氣過(guò)濾器的作用
諾冠NORGREN空氣過(guò)濾器的發(fā)展歷程 從氣源出來(lái)的壓縮空氣中含有過(guò)量的水汽和油滴,同時(shí)還有固體雜質(zhì),如鐵銹,、沙粒,、管道密封劑等,這些會(huì)損壞活塞密封環(huán),堵塞元器件上的小排氣孔,縮短元器件的使用壽命或使之失效.空氣過(guò)濾器的作用就是將壓縮空氣中的液態(tài)水、液態(tài)油滴分離出來(lái),并濾去空氣中的灰塵和固體雜質(zhì),但不能除去氣態(tài)的水和油
