法蘭式電(dian)(dian)加(jia)熱(re)管(guan)是(shi)采用U型管(guan)狀電(dian)(dian)熱(re)元(yuan)(yuan)件(jian)(jian)，依據(ju)加(jia)熱(re)不同(tong)介(jie)(jie)質(zhi)(zhi)設計(ji)規范，按照(zhao)功率配(pei)置(zhi)要求裝(zhuang)配(pei)在法蘭蓋上，插入需(xu)加(jia)熱(re)物料中，發(fa)熱(re)元(yuan)(yuan)件(jian)(jian)工作時所發(fa)出的大(da)量熱(re)量傳導給被加(jia)熱(re)介(jie)(jie)質(zhi)(zhi)使介(jie)(jie)質(zhi)(zhi)溫(wen)(wen)度(du)升高，達(da)到(dao)(dao)所需(xu)的工藝(yi)要求。當介(jie)(jie)質(zhi)(zhi)溫(wen)(wen)度(du)達(da)到(dao)(dao)工藝(yi)要求的設定值(zhi)時控制系統根據(ju)溫(wen)(wen)度(du)傳感(gan)器信號，經PID運算后(hou)調節電(dian)(dian)加(jia)熱(re)器輸出功率，對發(fa)熱(re)元(yuan)(yuan)件(jian)(jian)的電(dian)(dian)阻性負載實(shi)現溫(wen)(wen)度(du)控制。使介(jie)(jie)質(zhi)(zhi)溫(wen)(wen)度(du)均(jun)勻，達(da)到(dao)(dao)所需(xu)要求;當發(fa)熱(re)元(yuan)(yuan)件(jian)(jian)超溫(wen)(wen)或低(di)液位時，發(fa)熱(re)元(yuan)(yuan)件(jian)(jian)的聯(lian)鎖保(bao)護裝(zhuang)置(zhi)立(li)即切斷加(jia)熱(re)電(dian)(dian)源避免發(fa)熱(re)元(yuan)(yuan)件(jian)(jian)燒壞，延(yan)長(chang)使用壽命。

產品特點

法蘭式電加(jia)熱(re)管表(biao)面功(gong)率大，是空氣加(jia)熱(re)表(biao)面負荷(he)的2~4倍高(gao)度(du)密(mi)集式、結構緊(jin)湊。由于整(zheng)體(ti)短而密(mi)集，故穩定(ding)性好(hao)，安(an)裝無(wu)需支(zhi)架組合式大多采用(yong)(yong)(yong)(yong)氬弧(hu)焊(han)接(jie)(jie)方(fang)式使電熱(re)管于法蘭連接(jie)(jie)，也可利用(yong)(yong)(yong)(yong)緊(jin)固(gu)裝置的形式，即每支(zhi)電熱(re)管上(shang)焊(han)由緊(jin)固(gu)件(jian)。然后與法蘭蓋采用(yong)(yong)(yong)(yong)螺母鎖緊(jin)。管子于緊(jin)固(gu)件(jian)采用(yong)(yong)(yong)(yong)氬弧(hu)焊(han)接(jie)(jie)，緊(jin)固(gu)件(jian)密(mi)封處(chu)采用(yong)(yong)(yong)(yong)科學的工藝(yi)。單支(zhi)更換方(fang)便，節(jie)約以后的維修成本。
