法蘭電加熱管也稱插入式電加熱器
法蘭電加熱管性能及使用
法(fa)(fa)蘭加(jia)(jia)熱(re)器是(shi)由多支加(jia)(jia)熱(re)管焊接在法(fa)(fa)蘭上集(ji)中加(jia)(jia)熱(re)。主(zhu)要(yao)用(yong)于敞(chang)開式(shi)、封閉式(shi)的溶(rong)液箱和循環系統中加(jia)(jia)熱(re)用(yong)。
法蘭電加熱管優(you)點
表面功(gong)率大(da),使(shi)空氣(qi)加(jia)(jia)熱表面負(fu)荷(he)的(de)(de)(de)2~4倍,高度(du)密集(ji)式(shi)(shi)、結(jie)構緊湊。由于(yu)整體短而密集(ji),法(fa)蘭(lan)電(dian)(dian)加(jia)(jia)熱管(guan)(guan)(guan)故穩定性好,安裝(zhuang)(zhuang)無需支架。 組(zu)合(he)式(shi)(shi)法(fa)蘭(lan)加(jia)(jia)熱器大(da)多采(cai)用(yong)(yong)氬弧焊(han)接方(fang)(fang)式(shi)(shi)使(shi)電(dian)(dian)熱管(guan)(guan)(guan)于(yu)法(fa)蘭(lan)連接,也(ye)可利用(yong)(yong)緊固裝(zhuang)(zhuang)置的(de)(de)(de)形式(shi)(shi),即每支電(dian)(dian)熱管(guan)(guan)(guan)上焊(han)由緊固件(jian)。然后與法(fa)蘭(lan)蓋采(cai)用(yong)(yong)螺母鎖緊。管(guan)(guan)(guan)子于(yu)緊固件(jian)采(cai)用(yong)(yong)氬弧焊(han)接,永不泄漏。緊固件(jian)密封處采(cai)用(yong)(yong)科(ke)學(xue)的(de)(de)(de)工藝。單支更(geng)換極為(wei)方(fang)(fang)便,大(da)大(da)節約(yue)以后的(de)(de)(de)維(wei)修成(cheng)本 選擇進口及國(guo)內優質材料。科(ke)學(xue)的(de)(de)(de)生產工藝,嚴格的(de)(de)(de)質量管(guan)(guan)(guan)理,保證電(dian)(dian)熱管(guan)(guan)(guan)優越的(de)(de)(de)電(dian)(dian)氣(qi)性能。
法蘭電(dian)加熱管概(gai)述及工(gong)作原理
法蘭加熱(re)(re)器(qi)(qi):是(shi)采用U型管(guan)狀電(dian)(dian)熱(re)(re)元(yuan)件(jian)(jian),依據(ju)(ju)加熱(re)(re)不同(tong)介(jie)(jie)質(zhi)設計規(gui)范,按(an)照(zhao)功率配置要(yao)求(qiu)裝配在法蘭蓋上,插入需加熱(re)(re)物料中,發(fa)熱(re)(re)元(yuan)件(jian)(jian)工作時(shi)所發(fa)出的(de)(de)大(da)量熱(re)(re)量傳導給被加熱(re)(re)介(jie)(jie)質(zhi)使(shi)介(jie)(jie)質(zhi)溫(wen)度(du)(du)(du)升高,達到(dao)所需的(de)(de)工藝要(yao)求(qiu)。當(dang)介(jie)(jie)質(zhi)溫(wen)度(du)(du)(du)達到(dao)工藝要(yao)求(qiu)的(de)(de)設定值時(shi),控制系統根(gen)據(ju)(ju)溫(wen)度(du)(du)(du)傳感器(qi)(qi)信號,經PID 運算后調節電(dian)(dian)加熱(re)(re)器(qi)(qi)輸(shu)出功率,對(dui)發(fa)熱(re)(re)元(yuan)件(jian)(jian)的(de)(de)電(dian)(dian)阻性(xing)負載實現溫(wen)度(du)(du)(du)控制。使(shi)介(jie)(jie)質(zhi)溫(wen)度(du)(du)(du)均(jun)勻,達到(dao)所需要(yao)求(qiu);當(dang)發(fa)熱(re)(re)元(yuan)件(jian)(jian)超溫(wen)或低(di)液位時(shi),發(fa)熱(re)(re)元(yuan)件(jian)(jian)的(de)(de)聯(lian)鎖保護裝置立即(ji)切斷加熱(re)(re)電(dian)(dian)源避(bi)免發(fa)熱(re)(re)元(yuan)件(jian)(jian)燒壞,延長使(shi)用壽命(ming)。
