法(fa)蘭式電(dian)加熱(re)(re)(re)(re)管是采用(yong)U型管狀(zhuang)電(dian)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)，依據(ju)加熱(re)(re)(re)(re)不同介(jie)質設(she)計規(gui)范，按照功(gong)率配置要(yao)(yao)求(qiu)裝配在法(fa)蘭蓋上，插入需加熱(re)(re)(re)(re)物料中，發熱(re)(re)(re)(re)元(yuan)件(jian)(jian)工(gong)作時所(suo)(suo)(suo)發出(chu)(chu)的大量(liang)熱(re)(re)(re)(re)量(liang)傳導給被加熱(re)(re)(re)(re)介(jie)質使(shi)介(jie)質溫(wen)度(du)升(sheng)高(gao)，達(da)到(dao)所(suo)(suo)(suo)需的工(gong)藝(yi)要(yao)(yao)求(qiu)。當(dang)介(jie)質溫(wen)度(du)達(da)到(dao)工(gong)藝(yi)要(yao)(yao)求(qiu)的設(she)定值時控制系統(tong)根據(ju)溫(wen)度(du)傳感(gan)器信號，經(jing)PID運(yun)算(suan)后調節電(dian)加熱(re)(re)(re)(re)器輸出(chu)(chu)功(gong)率，對(dui)發熱(re)(re)(re)(re)元(yuan)件(jian)(jian)的電(dian)阻性負載實(shi)現溫(wen)度(du)控制。使(shi)介(jie)質溫(wen)度(du)均勻(yun)，達(da)到(dao)所(suo)(suo)(suo)需要(yao)(yao)求(qiu);當(dang)發熱(re)(re)(re)(re)元(yuan)件(jian)(jian)超溫(wen)或(huo)低液(ye)位(wei)時，發熱(re)(re)(re)(re)元(yuan)件(jian)(jian)的聯鎖(suo)保護裝置立即切斷加熱(re)(re)(re)(re)電(dian)源避免發熱(re)(re)(re)(re)元(yuan)件(jian)(jian)燒(shao)壞，延長使(shi)用(yong)壽(shou)命。

產品特點

法蘭式(shi)電加熱管表面功率大(da)，是空氣加熱表面負荷的2~4倍高度密集(ji)式(shi)、結構緊(jin)湊。由于(yu)整體短(duan)而密集(ji)，故穩定性好，安裝無需支(zhi)架組合式(shi)大(da)多采用(yong)(yong)氬弧焊接(jie)方(fang)(fang)式(shi)使電熱管于(yu)法蘭連接(jie)，也可(ke)利用(yong)(yong)緊(jin)固裝置(zhi)的形式(shi)，即每支(zhi)電熱管上焊由緊(jin)固件(jian)。然(ran)后與法蘭蓋采用(yong)(yong)螺母鎖緊(jin)。管子于(yu)緊(jin)固件(jian)采用(yong)(yong)氬弧焊接(jie)，緊(jin)固件(jian)密封處采用(yong)(yong)科學的工(gong)藝。單支(zhi)更(geng)換方(fang)(fang)便，節約以后的維修成本。
