法蘭加熱器概況
法(fa)(fa)蘭(lan)電(dian)(dian)(dian)(dian)(dian)熱(re)(re)(re)(re)管(也稱插入式(shi)電(dian)(dian)(dian)(dian)(dian)加(jia)(jia)熱(re)(re)(re)(re)器),是(shi)采(cai)用(yong)U型管狀(zhuang)電(dian)(dian)(dian)(dian)(dian)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian),依據加(jia)(jia)熱(re)(re)(re)(re)不同介質(zhi)設計規(gui)范,按照功(gong)(gong)率配(pei)置要(yao)(yao)求(qiu)裝配(pei)在法(fa)(fa)蘭(lan)蓋上,插入需(xu)加(jia)(jia)熱(re)(re)(re)(re)物料(liao)中,發熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian)工(gong)作時(shi)所發出的(de)(de)大量熱(re)(re)(re)(re)量傳導(dao)給(gei)被加(jia)(jia)熱(re)(re)(re)(re)介質(zhi)使(shi)(shi)(shi)介質(zhi)溫(wen)度升高,達到所需(xu)的(de)(de)工(gong)藝(yi)要(yao)(yao)求(qiu)。當介質(zhi)溫(wen)度達到工(gong)藝(yi)要(yao)(yao)求(qiu)的(de)(de)設定(ding)值時(shi),控制系統根(gen)據溫(wen)度傳感器信號(hao),經PID運算后調(diao)節電(dian)(dian)(dian)(dian)(dian)加(jia)(jia)熱(re)(re)(re)(re)器輸出功(gong)(gong)率,對發熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian)的(de)(de)電(dian)(dian)(dian)(dian)(dian)阻性負載(zai)實現溫(wen)度控制。使(shi)(shi)(shi)介質(zhi)溫(wen)度均勻,達到所需(xu)要(yao)(yao)求(qiu);當發熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian)超溫(wen)或(huo)低液位(wei)時(shi),發熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian)的(de)(de)聯(lian)鎖保(bao)(bao)護(hu)裝置立即切斷加(jia)(jia)熱(re)(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)源避免發熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian)燒壞,延長使(shi)(shi)(shi)用(yong)壽(shou)命。 法(fa)(fa)蘭(lan)電(dian)(dian)(dian)(dian)(dian)熱(re)(re)(re)(re)管主要(yao)(yao)針對石(shi)油、化工(gong)、食品、機械等(deng)行業各類儲罐、容器、油箱內物料(liao)保(bao)(bao)溫(wen)和加(jia)(jia)熱(re)(re)(re)(re)。連接方式(shi)可采(cai)用(yong)法(fa)(fa)蘭(lan)式(shi)或(huo)螺紋(wen)端面密封。
法蘭加熱器性能及使用
法(fa)蘭加(jia)熱器是由多支加(jia)熱管(guan)焊(han)接在法(fa)蘭上集中加(jia)熱。主要用于(yu)敞開式(shi)(shi)、封閉式(shi)(shi)的溶(rong)液箱(xiang)和循環(huan)系(xi)統中加(jia)熱用。
法蘭加熱器優點
表面功率大,使空氣加熱表面負荷的2~4倍,高度密集式、結構緊湊。由于整體短而密集,法蘭電加熱管故穩定性好,安裝無需支架。 組合式法蘭加熱器大多采用氬弧焊接方式使電熱管于法蘭連接,也可利用緊固裝置的形式,即每支電熱管上焊由緊固件。然后與法蘭蓋采用螺母鎖緊。管子于緊固件采用氬弧焊接,永不泄漏。緊固件密封處采用科學的工藝。單支更換極為方便,大大節約以后的維修成本 選擇進口及國內優質材料。科學的生產工藝,嚴格的質量管理,保證電熱管優越的電氣性能。
