法蘭加熱(re)(re)(re)(re)管(也稱(cheng)插(cha)入式電(dian)加熱(re)(re)(re)(re)器):是(shi)采用(yong)(yong)U型管狀(zhuang)電(dian)熱(re)(re)(re)(re)元件(jian)，依據加熱(re)(re)(re)(re)不(bu)同(tong)介質(zhi)(zhi)設(she)計規范，按照功(gong)率配置要求(qiu)(qiu)裝配在法蘭蓋上，插(cha)入需(xu)加熱(re)(re)(re)(re)物料(liao)中(zhong)，發(fa)熱(re)(re)(re)(re)元件(jian)工作時(shi)所發(fa)出的大量(liang)熱(re)(re)(re)(re)量(liang)傳(chuan)(chuan)導給(gei)被加熱(re)(re)(re)(re)介質(zhi)(zhi)使介質(zhi)(zhi)溫(wen)(wen)度升高(gao)，達(da)(da)到(dao)(dao)所需(xu)的工藝要求(qiu)(qiu)。當(dang)介質(zhi)(zhi)溫(wen)(wen)度達(da)(da)到(dao)(dao)工藝要求(qiu)(qiu)的設(she)定值時(shi)控制(zhi)系統根據溫(wen)(wen)度傳(chuan)(chuan)感器信號，經PID運算后調節電(dian)加熱(re)(re)(re)(re)器輸出功(gong)率，對發(fa)熱(re)(re)(re)(re)元件(jian)的電(dian)阻性負(fu)載實現溫(wen)(wen)度控制(zhi)。使介質(zhi)(zhi)溫(wen)(wen)度均勻(yun)，達(da)(da)到(dao)(dao)所需(xu)要求(qiu)(qiu);當(dang)發(fa)熱(re)(re)(re)(re)元件(jian)超(chao)溫(wen)(wen)或(huo)低液(ye)位時(shi)，發(fa)熱(re)(re)(re)(re)元件(jian)的聯鎖保護裝置立即切(qie)斷加熱(re)(re)(re)(re)電(dian)源避(bi)免發(fa)熱(re)(re)(re)(re)元件(jian)燒壞，延長使用(yong)(yong)壽命。

產品特點

法(fa)蘭(lan)加熱(re)(re)管表(biao)(biao)面功率(lv)大，是(shi)空氣加熱(re)(re)表(biao)(biao)面負荷的2~4倍高度密集式(shi)、結構緊(jin)湊。由于整體(ti)短而(er)密集，故穩定(ding)性好(hao)，安裝(zhuang)(zhuang)無需支(zhi)架組合式(shi)大多采(cai)用(yong)(yong)氬(ya)弧焊接方(fang)式(shi)使(shi)電熱(re)(re)管于法(fa)蘭(lan)連接，也可(ke)利(li)用(yong)(yong)緊(jin)固(gu)裝(zhuang)(zhuang)置的形式(shi)，即每支(zhi)電熱(re)(re)管上焊由緊(jin)固(gu)件。然(ran)后(hou)(hou)與法(fa)蘭(lan)蓋采(cai)用(yong)(yong)螺母鎖緊(jin)。管子(zi)于緊(jin)固(gu)件采(cai)用(yong)(yong)氬(ya)弧焊接，緊(jin)固(gu)件密封處(chu)采(cai)用(yong)(yong)科學(xue)的工藝。單支(zhi)更(geng)換(huan)方(fang)便，節約以后(hou)(hou)的維修成本(ben)。
