法蘭式電(dian)(dian)加熱(re)管是采用U型管狀電(dian)(dian)熱(re)元(yuan)件(jian)，依(yi)據加熱(re)不同(tong)介(jie)(jie)質(zhi)設計規范，按照功(gong)率(lv)(lv)配(pei)(pei)置(zhi)要(yao)求(qiu)裝(zhuang)配(pei)(pei)在法蘭蓋上，插入需(xu)加熱(re)物料中，發(fa)(fa)(fa)熱(re)元(yuan)件(jian)工(gong)作時(shi)所發(fa)(fa)(fa)出的大量(liang)熱(re)量(liang)傳導給被加熱(re)介(jie)(jie)質(zhi)使介(jie)(jie)質(zhi)溫(wen)(wen)度升(sheng)高，達(da)到(dao)所需(xu)的工(gong)藝要(yao)求(qiu)。當(dang)介(jie)(jie)質(zhi)溫(wen)(wen)度達(da)到(dao)工(gong)藝要(yao)求(qiu)的設定(ding)值時(shi)控制系(xi)統根據溫(wen)(wen)度傳感器(qi)信號，經(jing)PID運(yun)算(suan)后(hou)調(diao)節電(dian)(dian)加熱(re)器(qi)輸(shu)出功(gong)率(lv)(lv)，對發(fa)(fa)(fa)熱(re)元(yuan)件(jian)的電(dian)(dian)阻性負載(zai)實現溫(wen)(wen)度控制。使介(jie)(jie)質(zhi)溫(wen)(wen)度均(jun)勻，達(da)到(dao)所需(xu)要(yao)求(qiu);當(dang)發(fa)(fa)(fa)熱(re)元(yuan)件(jian)超溫(wen)(wen)或低(di)液位時(shi)，發(fa)(fa)(fa)熱(re)元(yuan)件(jian)的聯鎖保護(hu)裝(zhuang)置(zhi)立即切斷加熱(re)電(dian)(dian)源避免發(fa)(fa)(fa)熱(re)元(yuan)件(jian)燒壞(huai)，延長(chang)使用壽命。

產品特點

法蘭(lan)式(shi)電(dian)加(jia)熱管(guan)(guan)表面(mian)(mian)功率大，是空氣(qi)加(jia)熱表面(mian)(mian)負荷的2~4倍高度密集(ji)式(shi)、結構緊(jin)湊。由(you)于(yu)整(zheng)體短而密集(ji)，故穩(wen)定(ding)性(xing)好，安裝無需(xu)支架組(zu)合(he)式(shi)大多采(cai)用氬(ya)弧焊(han)接方式(shi)使電(dian)熱管(guan)(guan)于(yu)法蘭(lan)連接，也可利用緊(jin)固(gu)裝置的形式(shi)，即每(mei)支電(dian)熱管(guan)(guan)上(shang)焊(han)由(you)緊(jin)固(gu)件(jian)。然后與法蘭(lan)蓋采(cai)用螺母鎖緊(jin)。管(guan)(guan)子于(yu)緊(jin)固(gu)件(jian)采(cai)用氬(ya)弧焊(han)接，緊(jin)固(gu)件(jian)密封處采(cai)用科學的工藝(yi)。單(dan)支更換(huan)方便，節約以后的維修(xiu)成本。
