法蘭式電(dian)加(jia)熱(re)(re)管是采用U型管狀電(dian)熱(re)(re)元(yuan)(yuan)(yuan)件(jian)，依據(ju)加(jia)熱(re)(re)不同介質設計規范，按照(zhao)功率(lv)(lv)配置(zhi)要(yao)求(qiu)(qiu)裝配在法蘭蓋上(shang)，插(cha)入需(xu)(xu)加(jia)熱(re)(re)物料中(zhong)，發(fa)熱(re)(re)元(yuan)(yuan)(yuan)件(jian)工(gong)作時(shi)所發(fa)出的(de)(de)大量熱(re)(re)量傳導給被加(jia)熱(re)(re)介質使介質溫度(du)(du)升高，達(da)到(dao)所需(xu)(xu)的(de)(de)工(gong)藝(yi)要(yao)求(qiu)(qiu)。當介質溫度(du)(du)達(da)到(dao)工(gong)藝(yi)要(yao)求(qiu)(qiu)的(de)(de)設定值時(shi)控制系統根(gen)據(ju)溫度(du)(du)傳感(gan)器信號(hao)，經PID運算(suan)后調節(jie)電(dian)加(jia)熱(re)(re)器輸出功率(lv)(lv)，對發(fa)熱(re)(re)元(yuan)(yuan)(yuan)件(jian)的(de)(de)電(dian)阻(zu)性負載實現溫度(du)(du)控制。使介質溫度(du)(du)均勻，達(da)到(dao)所需(xu)(xu)要(yao)求(qiu)(qiu);當發(fa)熱(re)(re)元(yuan)(yuan)(yuan)件(jian)超溫或(huo)低液位時(shi)，發(fa)熱(re)(re)元(yuan)(yuan)(yuan)件(jian)的(de)(de)聯鎖保護裝置(zhi)立即切斷加(jia)熱(re)(re)電(dian)源避(bi)免(mian)發(fa)熱(re)(re)元(yuan)(yuan)(yuan)件(jian)燒壞，延長使用壽命。

產品特點

法(fa)(fa)蘭式電加(jia)熱管表(biao)面(mian)功率大，是空氣加(jia)熱表(biao)面(mian)負(fu)荷的2~4倍高度密(mi)集(ji)式、結(jie)構緊(jin)(jin)湊。由于整(zheng)體短而密(mi)集(ji)，故(gu)穩定性好，安裝無需支(zhi)(zhi)架(jia)組合式大多采(cai)用(yong)(yong)(yong)氬(ya)(ya)弧(hu)焊(han)接方式使電熱管于法(fa)(fa)蘭連(lian)接，也可(ke)利用(yong)(yong)(yong)緊(jin)(jin)固(gu)(gu)(gu)裝置的形式，即(ji)每支(zhi)(zhi)電熱管上焊(han)由緊(jin)(jin)固(gu)(gu)(gu)件(jian)(jian)。然后(hou)與法(fa)(fa)蘭蓋采(cai)用(yong)(yong)(yong)螺(luo)母鎖緊(jin)(jin)。管子于緊(jin)(jin)固(gu)(gu)(gu)件(jian)(jian)采(cai)用(yong)(yong)(yong)氬(ya)(ya)弧(hu)焊(han)接，緊(jin)(jin)固(gu)(gu)(gu)件(jian)(jian)密(mi)封處采(cai)用(yong)(yong)(yong)科學的工(gong)藝。單支(zhi)(zhi)更換方便，節(jie)約以后(hou)的維(wei)修成本。
