空(kong)氣加(jia)(jia)(jia)(jia)熱(re)(re)器(qi)(qi)也稱(cheng)為管(guan)(guan)(guan)(guan)道加(jia)(jia)(jia)(jia)熱(re)(re)器(qi)(qi)，丹東熔(rong)噴(pen)布電(dian)熱(re)(re)管(guan)(guan)(guan)(guan)，管(guan)(guan)(guan)(guan)道加(jia)(jia)(jia)(jia)熱(re)(re)器(qi)(qi)的主要(yao)由(you)電(dian)加(jia)(jia)(jia)(jia)熱(re)(re)管(guan)(guan)(guan)(guan)，內筒、保溫層、外殼(ke)、接線(xian)腔、電(dian)控系(xi)統幾個部分組成，其工作原理(li)是：冷空(kong)氣從(cong)(cong)進口(kou)進入(ru)管(guan)(guan)(guan)(guan)道加(jia)(jia)(jia)(jia)熱(re)(re)器(qi)(qi)內筒，在導(dao)流板的作用下與電(dian)加(jia)(jia)(jia)(jia)棒充分接觸，在出(chu)(chu)口(kou)測溫系(xi)統的監(jian)測下到達準確溫度后從(cong)(cong)出(chu)(chu)口(kou)流向(xiang)管(guan)(guan)(guan)(guan)路系(xi)統。管(guan)(guan)(guan)(guan)道空(kong)氣加(jia)(jia)(jia)(jia)熱(re)(re)器(qi)(qi)可以(yi)根據加(jia)(jia)(jia)(jia)熱(re)(re)的氣體種類、達到的溫度選擇加(jia)(jia)(jia)(jia)熱(re)(re)器(qi)(qi)的材(cai)質，也可以(yi)根據現場的使用情況定做加(jia)(jia)(jia)(jia)熱(re)(re)器(qi)(qi)的尺寸、形狀等。

空氣加熱(re)(re)器的(de)(de)基(ji)本(ben)保(bao)護是超溫(wen)(wen)保(bao)護，熔噴(pen)布(bu)電熱(re)(re)管(guan)生產廠家(jia)，用(yong)于防止加熱(re)(re)器出(chu)現(xian)意外的(de)(de)高溫(wen)(wen)而受損(sun)。保(bao)護裝置的(de)(de)動作設(she)定(ding)(ding)值是根(gen)(gen)據(ju)設(she)備允許的(de)(de)安全工(gong)作溫(wen)(wen)度(du)設(she)定(ding)(ding)的(de)(de)，不能(neng)隨意改(gai)變。超溫(wen)(wen)保(bao)護的(de)(de)功能(neng)與牽(qian)伸氣流(liu)的(de)(de)溫(wen)(wen)度(du)控(kong)制(zhi)是兩個不同概念。正常的(de)(de)溫(wen)(wen)度(du)控(kong)制(zhi)指(zhi)牽(qian)伸氣流(liu)的(de)(de)溫(wen)(wen)度(du)超過設(she)定(ding)(ding)值時，控(kong)制(zhi)系統會減少或切斷向電熱(re)(re)元件提供(gong)的(de)(de)能(neng)量，不影響設(she)備運行，熔噴(pen)布(bu)電熱(re)(re)管(guan)批(pi)發，溫(wen)(wen)度(du)傳感器裝在空氣加熱(re)(re)器出(chu)口的(de)(de)熱(re)(re)空氣中，設(she)定(ding)(ding)值可以根(gen)(gen)據(ju)工(gong)藝需要(yao)調整(zheng)。

空(kong)(kong)(kong)氣(qi)(qi)(qi)加(jia)(jia)(jia)熱器是熔(rong)噴生(sheng)產工藝當(dang)中的主要(yao)設備之一(yi)，因為(wei)熔(rong)噴工藝流程當(dang)中需要(yao)大量高溫潔凈的空(kong)(kong)(kong)氣(qi)(qi)(qi)，空(kong)(kong)(kong)氣(qi)(qi)(qi)加(jia)(jia)(jia)熱器是將羅茨風(feng)機或者空(kong)(kong)(kong)壓(ya)機傳(chuan)送(song)(song)過來的空(kong)(kong)(kong)氣(qi)(qi)(qi)加(jia)(jia)(jia)熱到準確溫度(du)后輸送(song)(song)到熔(rong)噴模(mo)頭當(dang)中。熔(rong)噴生(sheng)產線當(dang)中選擇(ze)的加(jia)(jia)(jia)熱器應該注意(yi)：工藝流程當(dang)中需要(yao)的空(kong)(kong)(kong)氣(qi)(qi)(qi)是潔凈的，首(shou)先輸入空(kong)(kong)(kong)氣(qi)(qi)(qi)加(jia)(jia)(jia)熱器的氣(qi)(qi)(qi)源應該是潔凈干(gan)燥的，加(jia)(jia)(jia)熱器當(dang)中和空(kong)(kong)(kong)氣(qi)(qi)(qi)接觸(chu)部分的材質至少需要(yao)是SUS304等級的。
