诺冠NORGREN空气过滤器的发展历程的迅速发展是与军事工业和电子工业的发展紧密相关的。玻璃纤维过滤介质用于空气过滤于1940年10月在美国取得。50年代,美国对玻璃纤维过滤纸的生产工艺进行了深入的研究,使空气过滤器得到了改善和发展。60年代,HEPA过滤器问世;70年代,采用微细玻璃纤维过滤纸作为过滤介质的HEPA过滤器,对013微米粒径的粒子过滤效率高达99.9998%。八十年代以来,随着新的测试方法的出现、使用评价的提高及对过滤性能要求的提高,发现HEPA过滤器存在着严重的问题,于是又产生了性能更高的ULPA过滤器。目前,各国仍在努力研究,估计不久就会出现更*空气过滤器。
编辑本段显著进展
诺冠NORGREN空气过滤器的发展历程 其中zui重要的是分隔板的去除,即无隔板过滤器的发展。无隔板过滤器不仅消除了分隔板损坏过滤介质的危险,而且有效地增加了过滤面积,提高了过滤效率,并降低了气流阻力,从而减少了能量消耗。此外,空气过滤器在耐高温、耐腐蚀以及防水、防菌等方面也取很大的进展,满足了一些特殊的需求。
空气过滤器的作用
诺冠NORGREN空气过滤器的发展历程 从气源出来的压缩空气中含有过量的水汽和油滴,同时还有固体杂质,如铁锈、沙粒、管道密封剂等,这些会损坏活塞密封环,堵塞元器件上的小排气孔,缩短元器件的使用寿命或使之失效.空气过滤器的作用就是将压缩空气中的液态水、液态油滴分离出来,并滤去空气中的灰尘和固体杂质,但不能除去气态的水和油
