烘干(gan)機工作原理：
空(kong)氣循(xun)環(huan)系統(tong)采(cai)(cai)用(yong)雙電(dian)機(ji)水平(ping)循(xun)環(huan)送(song)風方式，風循(xun)環(huan)均(jun)勻(yun)。風源(yuan)由循(xun)環(huan)送(song)風電(dian)機(ji)（采(cai)(cai)用(yong)無觸點(dian)開(kai)關(guan)）帶動(dong)風輪（Φ230）經由電(dian)熱(re)器，而將熱(re)風送(song)出，再經由風道(dao)至烘(hong)箱內室(shi)，再將使用(yong)后的空(kong)氣吸(xi)入(ru)風道(dao)成為風源(yuan)再度(du)循(xun)環(huan)，加熱(re)使用(yong)。確保(bao)室(shi)內溫(wen)度(du)均(jun)勻(yun)性。當因(yin)開(kai)關(guan)門動(dong)作引起溫(wen)度(du)值(zhi)發生(sheng)擺動(dong)，可介此送(song)風循(xun)環(huan)系統(tong)迅速恢復操作狀(zhuang)態溫(wen)度(du)值(zhi)。
老化試驗箱采用國(guo)外的(de)加熱氣流方法，解決了(le)原轉盤(pan)式的(de)溫度(du)不均勻先天缺陷(xian)，同時大大提高(gao)了(le)試樣(yang)放置的(de)安全性，有效空間利用率(lv)是原轉盤(pan)式的(de)200%以上，適(shi)用于(yu)電子元(yuan)件(jian)(jian)，橡膠零部件(jian)(jian)等材料在高(gao)溫下的(de)老化適(shi)應性試驗。
烘(hong)(hong)干(gan)(gan)(gan)機(ji)根(gen)據性能(neng)可分為可編程烘(hong)(hong)烘(hong)(hong)干(gan)(gan)(gan)機(ji)、精(jing)密烘(hong)(hong)箱充(chong)氮烘(hong)(hong)干(gan)(gan)(gan)機(ji)、真空烘(hong)(hong)干(gan)(gan)(gan)機(ji)、防爆烘(hong)(hong)干(gan)(gan)(gan)機(ji)、電熱鼓風烘(hong)(hong)干(gan)(gan)(gan)機(ji)，熱風循環烘(hong)(hong)干(gan)(gan)(gan)機(ji)等。方泛適(shi)用于(yu)各(ge)行各(ge)業需(xu)要烘(hong)(hong)干(gan)(gan)(gan)加熱的(de)元器件。
