風道循(xun)環加(jia)熱(re)器簡介
風道(dao)(dao)循環加(jia)熱(re)(re)器(qi)是專(zhuan)門(men)為氣體(ti)加(jia)熱(re)(re)的新型加(jia)熱(re)(re)設備(bei),該設備(bei)由風道(dao)(dao)電加(jia)熱(re)(re)器(qi)本體(ti)和控(kong)制(zhi)系(xi)(xi)統兩部分組成。發(fa)熱(re)(re)元(yuan)件(jian)采用(yong)1Cr18Ni9Ti不銹鋼 無(wu)縫管(guan)作保(bao)護套管(guan),0Cr27Al7MO2高溫(wen)(wen)(wen)電阻合金絲、結晶氧化鎂粉(fen),經(jing)壓縮工藝成型,使電加(jia)熱(re)(re)元(yuan)件(jian)的使用(yong)壽命得以保(bao)證(zheng)。控(kong)制(zhi)部分采用(yong)高精度 數顯(xian)式(shi)溫(wen)(wen)(wen)控(kong)儀等組成可 調測(ce)溫(wen)(wen)(wen)、恒溫(wen)(wen)(wen)系(xi)(xi)統,保(bao)證(zheng)了(le)電加(jia)熱(re)(re)器(qi)的正常運行。
風(feng)(feng)道(dao)(dao)循環(huan)加(jia)(jia)熱器(qi)(qi)(qi)主要用(yong)于風(feng)(feng)道(dao)(dao)中(zhong)的空(kong)氣(qi)加(jia)(jia)熱,規格分為低溫(wen)(wen)、中(zhong)溫(wen)(wen)、 高(gao)溫(wen)(wen)三種形式,在(zai)(zai)結構上(shang)的共同(tong)之處是采(cai)用(yong)鋼板支撐電(dian)熱管(guan)以(yi)減少(shao)電(dian)熱管(guan)的振動(dong),接線盒(he)中(zhong)都裝(zhuang)有(you)超(chao)(chao)(chao)(chao)溫(wen)(wen)控制裝(zhuang)置(zhi)。另在(zai)(zai)控制方面除裝(zhuang)有(you)超(chao)(chao)(chao)(chao)溫(wen)(wen)保(bao)護外(wai) ,還(huan)在(zai)(zai)風(feng)(feng)機(ji)與加(jia)(jia)熱器(qi)(qi)(qi)之間加(jia)(jia)裝(zhuang)聯運裝(zhuang)置(zhi),以(yi)確保(bao)電(dian)加(jia)(jia)熱器(qi)(qi)(qi)起動(dong)必須(xu)在(zai)(zai)風(feng)(feng)機(ji) 起動(dong)之后(hou),在(zai)(zai)加(jia)(jia)熱器(qi)(qi)(qi)前(qian)后(hou)加(jia)(jia)一差壓(ya)裝(zhuang)置(zhi),以(yi)防風(feng)(feng)機(ji)故障,通道(dao)(dao)加(jia)(jia)熱器(qi)(qi)(qi)加(jia)(jia)熱 的氣(qi)體(ti)壓(ya)力(li)一般不(bu)應超(chao)(chao)(chao)(chao)過(guo)0.3Kg/cm2,如需(xu)超(chao)(chao)(chao)(chao)過(guo)以(yi)上(shang)壓(ya)力(li),請選(xuan)用(yong)循環(huan)式 電(dian)加(jia)(jia)熱器(qi)(qi)(qi);低溫(wen)(wen)型加(jia)(jia)熱器(qi)(qi)(qi)氣(qi)體(ti)加(jia)(jia)熱*溫(wen)(wen)度不(bu)超(chao)(chao)(chao)(chao)過(guo)160℃;中(zhong)溫(wen)(wen)型不(bu)超(chao)(chao)(chao)(chao)過(guo) 260℃;高(gao)溫(wen)(wen)型不(bu)超(chao)(chao)(chao)(chao)過(guo)500℃。
