法蘭式電(dian)(dian)(dian)加(jia)熱(re)(re)(re)管是采用U型管狀電(dian)(dian)(dian)熱(re)(re)(re)元(yuan)(yuan)件，依(yi)據加(jia)熱(re)(re)(re)不(bu)同(tong)介(jie)質(zhi)(zhi)(zhi)(zhi)設(she)計規(gui)范，按照(zhao)功率(lv)配置(zhi)要(yao)(yao)求(qiu)裝(zhuang)配在法蘭蓋上，插入需加(jia)熱(re)(re)(re)物料中(zhong)，發熱(re)(re)(re)元(yuan)(yuan)件工作時所發出(chu)(chu)的大量熱(re)(re)(re)量傳導給(gei)被加(jia)熱(re)(re)(re)介(jie)質(zhi)(zhi)(zhi)(zhi)使介(jie)質(zhi)(zhi)(zhi)(zhi)溫度(du)升高，達(da)(da)到(dao)所需的工藝要(yao)(yao)求(qiu)。當介(jie)質(zhi)(zhi)(zhi)(zhi)溫度(du)達(da)(da)到(dao)工藝要(yao)(yao)求(qiu)的設(she)定值(zhi)時控(kong)制系統(tong)根據溫度(du)傳感(gan)器(qi)信(xin)號(hao)，經(jing)PID運算(suan)后調(diao)節電(dian)(dian)(dian)加(jia)熱(re)(re)(re)器(qi)輸(shu)出(chu)(chu)功率(lv)，對發熱(re)(re)(re)元(yuan)(yuan)件的電(dian)(dian)(dian)阻性負(fu)載實現(xian)溫度(du)控(kong)制。使介(jie)質(zhi)(zhi)(zhi)(zhi)溫度(du)均勻，達(da)(da)到(dao)所需要(yao)(yao)求(qiu);當發熱(re)(re)(re)元(yuan)(yuan)件超溫或(huo)低液位時，發熱(re)(re)(re)元(yuan)(yuan)件的聯鎖保護(hu)裝(zhuang)置(zhi)立即(ji)切斷加(jia)熱(re)(re)(re)電(dian)(dian)(dian)源避免發熱(re)(re)(re)元(yuan)(yuan)件燒壞，延長使用壽命。

產品特點

法蘭式(shi)電加熱管(guan)(guan)表面(mian)功率大，是(shi)空(kong)氣(qi)加熱表面(mian)負荷的2~4倍高度密集式(shi)、結構(gou)緊(jin)湊。由(you)于(yu)整(zheng)體短而(er)密集，故(gu)穩定(ding)性好，安裝無需支(zhi)架(jia)組合(he)式(shi)大多采用(yong)(yong)氬弧焊接(jie)方式(shi)使(shi)電熱管(guan)(guan)于(yu)法蘭連接(jie)，也可利用(yong)(yong)緊(jin)固(gu)裝置的形式(shi)，即每支(zhi)電熱管(guan)(guan)上焊由(you)緊(jin)固(gu)件(jian)(jian)(jian)。然后與(yu)法蘭蓋采用(yong)(yong)螺母鎖(suo)緊(jin)。管(guan)(guan)子于(yu)緊(jin)固(gu)件(jian)(jian)(jian)采用(yong)(yong)氬弧焊接(jie)，緊(jin)固(gu)件(jian)(jian)(jian)密封處采用(yong)(yong)科學(xue)的工藝。單支(zhi)更(geng)換方便，節約(yue)以后的維(wei)修成本。
