法蘭(lan)式電(dian)(dian)加(jia)(jia)熱(re)(re)(re)管(guan)(guan)是采用U型(xing)管(guan)(guan)狀電(dian)(dian)熱(re)(re)(re)元(yuan)件(jian)，依據(ju)加(jia)(jia)熱(re)(re)(re)不同(tong)介質設(she)計規范，按照功率配(pei)置要(yao)求(qiu)裝配(pei)在(zai)法蘭(lan)蓋上，插入需(xu)加(jia)(jia)熱(re)(re)(re)物料中，發(fa)(fa)熱(re)(re)(re)元(yuan)件(jian)工(gong)作時所發(fa)(fa)出的(de)(de)大量(liang)熱(re)(re)(re)量(liang)傳(chuan)導給被加(jia)(jia)熱(re)(re)(re)介質使介質溫度(du)升高，達到(dao)(dao)所需(xu)的(de)(de)工(gong)藝要(yao)求(qiu)。當(dang)介質溫度(du)達到(dao)(dao)工(gong)藝要(yao)求(qiu)的(de)(de)設(she)定值時控制系統根據(ju)溫度(du)傳(chuan)感器信號，經PID運(yun)算后調節電(dian)(dian)加(jia)(jia)熱(re)(re)(re)器輸出功率，對發(fa)(fa)熱(re)(re)(re)元(yuan)件(jian)的(de)(de)電(dian)(dian)阻性負(fu)載實現溫度(du)控制。使介質溫度(du)均勻，達到(dao)(dao)所需(xu)要(yao)求(qiu);當(dang)發(fa)(fa)熱(re)(re)(re)元(yuan)件(jian)超溫或低液位時，發(fa)(fa)熱(re)(re)(re)元(yuan)件(jian)的(de)(de)聯(lian)鎖保護裝置立即切(qie)斷加(jia)(jia)熱(re)(re)(re)電(dian)(dian)源避(bi)免發(fa)(fa)熱(re)(re)(re)元(yuan)件(jian)燒壞，延長使用壽命。

產品特點

法(fa)(fa)蘭(lan)式電加熱(re)(re)管(guan)表(biao)面(mian)功率大，是空氣(qi)加熱(re)(re)表(biao)面(mian)負荷的2~4倍高度密(mi)集式、結構緊(jin)湊。由于(yu)整體短而密(mi)集，故(gu)穩定性好，安裝無需(xu)支(zhi)(zhi)架組(zu)合(he)式大多采用(yong)(yong)(yong)氬(ya)弧焊(han)接(jie)方(fang)式使(shi)電熱(re)(re)管(guan)于(yu)法(fa)(fa)蘭(lan)連(lian)接(jie)，也可(ke)利用(yong)(yong)(yong)緊(jin)固(gu)裝置的形式，即每(mei)支(zhi)(zhi)電熱(re)(re)管(guan)上焊(han)由緊(jin)固(gu)件。然后與法(fa)(fa)蘭(lan)蓋采用(yong)(yong)(yong)螺母鎖緊(jin)。管(guan)子于(yu)緊(jin)固(gu)件采用(yong)(yong)(yong)氬(ya)弧焊(han)接(jie)，緊(jin)固(gu)件密(mi)封處采用(yong)(yong)(yong)科學的工藝。單支(zhi)(zhi)更換方(fang)便，節約以后的維修成(cheng)本。
