防爆法蘭電熱器性能及使用
法蘭加(jia)熱器(qi)是由多支加(jia)熱管(guan)焊接在法蘭上集中(zhong)加(jia)熱。主要用(yong)于敞(chang)開式(shi)、封(feng)閉式(shi)的溶(rong)液箱和循環系(xi)統中(zhong)加(jia)熱用(yong)。
防爆法蘭電熱器優點
防爆法(fa)蘭電(dian)熱(re)(re)管(guan)(guan)表面(mian)功率大(da),使(shi)空氣加熱(re)(re)表面(mian)負荷的2~4倍,高度(du)密集式(shi)、結構緊湊。由于(yu)整(zheng)體短(duan)而密集,故穩定性(xing)好,安裝無需支(zhi)架。 組合(he)式(shi)法(fa)蘭加熱(re)(re)器大(da)多采用氬(ya)弧焊接方式(shi)使(shi)電(dian)熱(re)(re)管(guan)(guan)于(yu)法(fa)蘭連接,也可利用緊固(gu)(gu)裝置(zhi)的形式(shi),即每(mei)支(zhi)電(dian)熱(re)(re)管(guan)(guan)上焊由緊固(gu)(gu)件(jian)。然后與法(fa)蘭蓋(gai)采用螺(luo)母鎖緊。管(guan)(guan)子于(yu)緊固(gu)(gu)件(jian)采用氬(ya)弧焊接,永不(bu)泄漏。緊固(gu)(gu)件(jian)密封處采用科學的工(gong)藝。單(dan)支(zhi)更換(huan)極(ji)為方便,大(da)大(da)節約以后的維(wei)修(xiu)成本 選擇進口及國內(nei)優質材(cai)料(liao)。科學的生(sheng)產工(gong)藝,嚴格的質量管(guan)(guan)理,保證(zheng)電(dian)熱(re)(re)管(guan)(guan)優越的電(dian)氣性(xing)能。
防爆法蘭電熱器概述及工作原理
法蘭加(jia)熱(re)(re)(re)(re)(re)器:是采用U型管狀電(dian)熱(re)(re)(re)(re)(re)元(yuan)件(jian),依據(ju)加(jia)熱(re)(re)(re)(re)(re)不(bu)同介質(zhi)(zhi)設計規范(fan),按照(zhao)功(gong)(gong)率配(pei)置要(yao)(yao)求(qiu)裝配(pei)在法蘭蓋(gai)上(shang),插入(ru)需(xu)加(jia)熱(re)(re)(re)(re)(re)物料中,發(fa)熱(re)(re)(re)(re)(re)元(yuan)件(jian)工(gong)作時(shi)所(suo)發(fa)出(chu)(chu)的(de)大量熱(re)(re)(re)(re)(re)量傳導(dao)給被加(jia)熱(re)(re)(re)(re)(re)介質(zhi)(zhi)使介質(zhi)(zhi)溫(wen)度(du)升高,達到(dao)所(suo)需(xu)的(de)工(gong)藝要(yao)(yao)求(qiu)。當(dang)介質(zhi)(zhi)溫(wen)度(du)達到(dao)工(gong)藝要(yao)(yao)求(qiu)的(de)設定值時(shi),控制系(xi)統根據(ju)溫(wen)度(du)傳感器信號,經PID 運算(suan)后調節電(dian)加(jia)熱(re)(re)(re)(re)(re)器輸出(chu)(chu)功(gong)(gong)率,對發(fa)熱(re)(re)(re)(re)(re)元(yuan)件(jian)的(de)電(dian)阻性負(fu)載實現溫(wen)度(du)控制。使介質(zhi)(zhi)溫(wen)度(du)均勻,達到(dao)所(suo)需(xu)要(yao)(yao)求(qiu);當(dang)發(fa)熱(re)(re)(re)(re)(re)元(yuan)件(jian)超溫(wen)或低液(ye)位時(shi),發(fa)熱(re)(re)(re)(re)(re)元(yuan)件(jian)的(de)聯鎖保護(hu)裝置立(li)即切斷加(jia)熱(re)(re)(re)(re)(re)電(dian)源避(bi)免發(fa)熱(re)(re)(re)(re)(re)元(yuan)件(jian)燒壞,延長使用壽命。
