風道循環加熱器簡(jian)介
風(feng)道(dao)循環加(jia)(jia)(jia)熱器是專門為氣體加(jia)(jia)(jia)熱的(de)新(xin)型(xing)加(jia)(jia)(jia)熱設備(bei),該設備(bei)由(you)風(feng)道(dao)電加(jia)(jia)(jia)熱器本(ben)體和控(kong)制(zhi)(zhi)系統兩部分(fen)組(zu)成(cheng)。發熱元(yuan)件采(cai)用(yong)1Cr18Ni9Ti不銹鋼 無縫管作保(bao)(bao)護套管,0Cr27Al7MO2高(gao)溫電阻合金絲、結晶氧化鎂粉,經壓縮工藝(yi)成(cheng)型(xing),使電加(jia)(jia)(jia)熱元(yuan)件的(de)使用(yong)壽(shou)命得以保(bao)(bao)證(zheng)。控(kong)制(zhi)(zhi)部分(fen)采(cai)用(yong)高(gao)精度 數顯式溫控(kong)儀(yi)等(deng)組(zu)成(cheng)可 調測溫、恒溫系統,保(bao)(bao)證(zheng)了電加(jia)(jia)(jia)熱器的(de)正常(chang)運行。
風道循環(huan)(huan)加(jia)(jia)(jia)熱(re)(re)器(qi)主(zhu)要用(yong)于風道中(zhong)(zhong)的(de)(de)(de)空氣(qi)加(jia)(jia)(jia)熱(re)(re),規格分為低溫(wen)(wen)(wen)、中(zhong)(zhong)溫(wen)(wen)(wen)、 高(gao)溫(wen)(wen)(wen)三種形(xing)式,在(zai)結構上的(de)(de)(de)共同之(zhi)(zhi)處是采用(yong)鋼板支撐電熱(re)(re)管(guan)以(yi)(yi)減少電熱(re)(re)管(guan)的(de)(de)(de)振動(dong)(dong),接線盒中(zhong)(zhong)都裝有超(chao)(chao)(chao)(chao)溫(wen)(wen)(wen)控制裝置。另(ling)在(zai)控制方面除裝有超(chao)(chao)(chao)(chao)溫(wen)(wen)(wen)保護外 ,還在(zai)風機與(yu)加(jia)(jia)(jia)熱(re)(re)器(qi)之(zhi)(zhi)間加(jia)(jia)(jia)裝聯運(yun)裝置,以(yi)(yi)確保電加(jia)(jia)(jia)熱(re)(re)器(qi)起(qi)動(dong)(dong)必(bi)須在(zai)風機 起(qi)動(dong)(dong)之(zhi)(zhi)后,在(zai)加(jia)(jia)(jia)熱(re)(re)器(qi)前后加(jia)(jia)(jia)一(yi)差壓(ya)裝置,以(yi)(yi)防風機故(gu)障(zhang),通道加(jia)(jia)(jia)熱(re)(re)器(qi)加(jia)(jia)(jia)熱(re)(re) 的(de)(de)(de)氣(qi)體(ti)壓(ya)力一(yi)般(ban)不應超(chao)(chao)(chao)(chao)過0.3Kg/cm2,如(ru)需超(chao)(chao)(chao)(chao)過以(yi)(yi)上壓(ya)力,請選用(yong)循環(huan)(huan)式 電加(jia)(jia)(jia)熱(re)(re)器(qi);低溫(wen)(wen)(wen)型加(jia)(jia)(jia)熱(re)(re)器(qi)氣(qi)體(ti)加(jia)(jia)(jia)熱(re)(re)*溫(wen)(wen)(wen)度不超(chao)(chao)(chao)(chao)過160℃;中(zhong)(zhong)溫(wen)(wen)(wen)型不超(chao)(chao)(chao)(chao)過 260℃;高(gao)溫(wen)(wen)(wen)型不超(chao)(chao)(chao)(chao)過500℃。
