法蘭(lan)加(jia)(jia)熱(re)管(也(ye)稱插入(ru)式電(dian)(dian)(dian)加(jia)(jia)熱(re)器(qi)(qi)):是采(cai)用(yong)(yong)U型(xing)管狀(zhuang)電(dian)(dian)(dian)熱(re)元(yuan)(yuan)(yuan)件(jian)，依據加(jia)(jia)熱(re)不同介(jie)質設計規范，按照功(gong)率(lv)配(pei)置(zhi)(zhi)要求(qiu)裝(zhuang)配(pei)在(zai)法蘭(lan)蓋上，插入(ru)需加(jia)(jia)熱(re)物料中，發(fa)(fa)熱(re)元(yuan)(yuan)(yuan)件(jian)工作時所(suo)(suo)發(fa)(fa)出(chu)的大量(liang)熱(re)量(liang)傳(chuan)導給被加(jia)(jia)熱(re)介(jie)質使(shi)介(jie)質溫(wen)(wen)度升(sheng)高(gao)，達(da)到(dao)所(suo)(suo)需的工藝要求(qiu)。當介(jie)質溫(wen)(wen)度達(da)到(dao)工藝要求(qiu)的設定值時控(kong)制系統根據溫(wen)(wen)度傳(chuan)感器(qi)(qi)信號，經(jing)PID運(yun)算后調節電(dian)(dian)(dian)加(jia)(jia)熱(re)器(qi)(qi)輸出(chu)功(gong)率(lv)，對發(fa)(fa)熱(re)元(yuan)(yuan)(yuan)件(jian)的電(dian)(dian)(dian)阻性負載(zai)實(shi)現(xian)溫(wen)(wen)度控(kong)制。使(shi)介(jie)質溫(wen)(wen)度均勻(yun)，達(da)到(dao)所(suo)(suo)需要求(qiu);當發(fa)(fa)熱(re)元(yuan)(yuan)(yuan)件(jian)超溫(wen)(wen)或(huo)低液位時，發(fa)(fa)熱(re)元(yuan)(yuan)(yuan)件(jian)的聯(lian)鎖保護裝(zhuang)置(zhi)(zhi)立(li)即切斷加(jia)(jia)熱(re)電(dian)(dian)(dian)源避免發(fa)(fa)熱(re)元(yuan)(yuan)(yuan)件(jian)燒壞，延長使(shi)用(yong)(yong)壽命。

產品特點

法蘭加熱(re)管表面(mian)(mian)功率大，是空(kong)氣(qi)加熱(re)表面(mian)(mian)負荷(he)的2~4倍高度密(mi)集式(shi)(shi)、結構緊(jin)湊。由于(yu)整(zheng)體(ti)短而密(mi)集，故穩定性好，安裝無(wu)需支架組(zu)合式(shi)(shi)大多采(cai)用(yong)氬(ya)弧(hu)焊接方式(shi)(shi)使(shi)電熱(re)管于(yu)法蘭連接，也可利用(yong)緊(jin)固(gu)(gu)裝置(zhi)的形式(shi)(shi)，即每支電熱(re)管上焊由緊(jin)固(gu)(gu)件(jian)。然后與法蘭蓋(gai)采(cai)用(yong)螺母(mu)鎖緊(jin)。管子于(yu)緊(jin)固(gu)(gu)件(jian)采(cai)用(yong)氬(ya)弧(hu)焊接，緊(jin)固(gu)(gu)件(jian)密(mi)封處采(cai)用(yong)科(ke)學的工藝。單支更(geng)換(huan)方便(bian)，節約以后的維修成本(ben)。
