熔(rong)噴布空氣(qi)(qi)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)運行原理(li)，在熔(rong)噴系(xi)統中，大部分都(dou)是使用(yong)由電加(jia)(jia)(jia)熱(re)(re)(re)的空氣(qi)(qi)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)。在空氣(qi)(qi)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)中，一般裝有(you)多個溫(wen)度(du)傳感器(qi)(qi)(qi)，一些功率(lv)較小(xiao)的加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)，僅在加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)的筒體上裝設測(ce)溫(wen)傳感器(qi)(qi)(qi)，對加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)提供超溫(wen)保護(hu)。熔(rong)噴加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)有(you)本(ben)體和控制系(xi)統兩部分組成。發熱(re)(re)(re)元件采用(yong)不銹(xiu)鋼(gang)鋼(gang)管(guan)(guan)做保護(hu)套管(guan)(guan)，高溫(wen)電阻(zu)合金(jin)絲(si)，結(jie)晶粉(fen)，丹東熔(rong)噴布電熱(re)(re)(re)管(guan)(guan)，經壓縮工藝成型。

空(kong)氣(qi)(qi)(qi)管道電加熱(re)(re)器(qi)熔(rong)噴(pen)工(gong)藝需(xu)(xu)用(yong)大量(liang)的熱(re)(re)空(kong)氣(qi)(qi)(qi)。空(kong)壓機輸(shu)出的壓縮空(kong)氣(qi)(qi)(qi)經除濕過濾后(hou)(hou)輸(shu)送(song)到空(kong)氣(qi)(qi)(qi)加熱(re)(re)器(qi)加熱(re)(re)，然后(hou)(hou)再(zai)送(song)至熔(rong)噴(pen)模頭組合件。空(kong)氣(qi)(qi)(qi)加熱(re)(re)器(qi)殼(ke)體及加熱(re)(re)元件要(yao)能抵抗高溫(wen)空(kong)氣(qi)(qi)(qi)的氧化(hua)作用(yong)，熔(rong)噴(pen)布電熱(re)(re)管廠，因此材料必須選用(yong)不銹鋼。根據熔(rong)噴(pen)氣(qi)(qi)(qi)流(liu)牽伸(shen)(shen)工(gong)藝的需(xu)(xu)要(yao)，熔(rong)噴(pen)布電熱(re)(re)管采購，熔(rong)噴(pen)牽伸(shen)(shen)氣(qi)(qi)(qi)流(liu)的溫(wen)度一(yi)定要(yao)高于聚(ju)合物(wu)的熔(rong)點。與(yu)紡粘紡絲(si)系統(tong)使用(yong)冷(leng)卻氣(qi)(qi)(qi)流(liu)充(chong)當牽伸(shen)(shen)氣(qi)(qi)(qi)流(liu)不同(tong)，熔(rong)噴(pen)牽伸(shen)(shen)系統(tong)需(xu)(xu)要(yao)增加空(kong)氣(qi)(qi)(qi)加熱(re)(re)器(qi)加熱(re)(re)牽伸(shen)(shen)氣(qi)(qi)(qi)流(liu)以滿(man)足工(gong)藝要(yao)求。

空(kong)氣加(jia)熱(re)(re)(re)(re)器是(shi)熔(rong)噴生(sheng)產工藝當(dang)中(zhong)的(de)主要(yao)設(she)備之(zhi)一(yi)，因(yin)為熔(rong)噴工藝流程當(dang)中(zhong)需要(yao)大量高(gao)溫潔凈的(de)空(kong)氣，空(kong)氣加(jia)熱(re)(re)(re)(re)器是(shi)將(jiang)羅茨風機(ji)(ji)(ji)或(huo)者(zhe)空(kong)壓機(ji)(ji)(ji)傳送過來的(de)空(kong)氣加(jia)熱(re)(re)(re)(re)到(dao)準確溫度(du)后輸送到(dao)熔(rong)噴模頭(tou)當(dang)中(zhong)。因(yin)為正常流程當(dang)中(zhong)的(de)氣源是(shi)空(kong)壓機(ji)(ji)(ji)或(huo)者(zhe)羅茨風機(ji)(ji)(ji)提供的(de)，所以空(kong)氣加(jia)熱(re)(re)(re)(re)器要(yao)選擇管道式的(de)有承壓能力的(de)加(jia)熱(re)(re)(re)(re)器；加(jia)熱(re)(re)(re)(re)器選型(xing)要(yao)詳細考慮風量、溫差、管路運(yun)送當(dang)中(zhong)的(de)熱(re)(re)(re)(re)量損失等因(yin)素。
