法蘭式電(dian)(dian)加熱(re)(re)管是(shi)采用U型(xing)管狀電(dian)(dian)熱(re)(re)元(yuan)件(jian)(jian)(jian)，依(yi)據(ju)加熱(re)(re)不同(tong)介(jie)質(zhi)設計規范(fan)，按照(zhao)功率(lv)(lv)配(pei)置要求(qiu)裝(zhuang)(zhuang)配(pei)在(zai)法蘭蓋(gai)上，插入需(xu)(xu)加熱(re)(re)物料中，發(fa)(fa)(fa)熱(re)(re)元(yuan)件(jian)(jian)(jian)工(gong)作時所(suo)發(fa)(fa)(fa)出的(de)大量(liang)熱(re)(re)量(liang)傳導給(gei)被加熱(re)(re)介(jie)質(zhi)使(shi)介(jie)質(zhi)溫(wen)(wen)度(du)(du)升高，達(da)到所(suo)需(xu)(xu)的(de)工(gong)藝要求(qiu)。當介(jie)質(zhi)溫(wen)(wen)度(du)(du)達(da)到工(gong)藝要求(qiu)的(de)設定值時控(kong)制(zhi)系統(tong)根據(ju)溫(wen)(wen)度(du)(du)傳感(gan)器信(xin)號，經PID運算后調節電(dian)(dian)加熱(re)(re)器輸出功率(lv)(lv)，對發(fa)(fa)(fa)熱(re)(re)元(yuan)件(jian)(jian)(jian)的(de)電(dian)(dian)阻性負載實現溫(wen)(wen)度(du)(du)控(kong)制(zhi)。使(shi)介(jie)質(zhi)溫(wen)(wen)度(du)(du)均勻，達(da)到所(suo)需(xu)(xu)要求(qiu);當發(fa)(fa)(fa)熱(re)(re)元(yuan)件(jian)(jian)(jian)超溫(wen)(wen)或低液(ye)位時，發(fa)(fa)(fa)熱(re)(re)元(yuan)件(jian)(jian)(jian)的(de)聯鎖(suo)保護裝(zhuang)(zhuang)置立即(ji)切斷加熱(re)(re)電(dian)(dian)源避免發(fa)(fa)(fa)熱(re)(re)元(yuan)件(jian)(jian)(jian)燒(shao)壞，延長使(shi)用壽命。

產品特點

法(fa)蘭(lan)式(shi)電加熱管(guan)表面功率大(da)，是空氣(qi)加熱表面負(fu)荷的2~4倍高度密集式(shi)、結構緊(jin)(jin)湊。由于(yu)(yu)整體(ti)短而密集，故穩(wen)定性(xing)好，安裝無(wu)需支架組合(he)式(shi)大(da)多(duo)采(cai)(cai)用氬弧焊接(jie)方式(shi)使(shi)電熱管(guan)于(yu)(yu)法(fa)蘭(lan)連接(jie)，也可利用緊(jin)(jin)固(gu)裝置的形式(shi)，即每支電熱管(guan)上焊由緊(jin)(jin)固(gu)件(jian)。然后與法(fa)蘭(lan)蓋采(cai)(cai)用螺母鎖緊(jin)(jin)。管(guan)子于(yu)(yu)緊(jin)(jin)固(gu)件(jian)采(cai)(cai)用氬弧焊接(jie)，緊(jin)(jin)固(gu)件(jian)密封(feng)處采(cai)(cai)用科學的工藝。單(dan)支更換方便(bian)，節(jie)約以后的維修成本(ben)。
