防爆法蘭電熱器性能及使用
法(fa)蘭加(jia)(jia)熱(re)器(qi)是由多支加(jia)(jia)熱(re)管(guan)焊接在法(fa)蘭上集中(zhong)加(jia)(jia)熱(re)。主要用(yong)于敞開式、封閉(bi)式的溶液箱和循環系統中(zhong)加(jia)(jia)熱(re)用(yong)。
防爆法蘭電熱器優點
防爆(bao)法(fa)蘭電(dian)(dian)熱(re)管(guan)表面功率大(da),使(shi)空氣(qi)加熱(re)表面負荷的2~4倍,高(gao)度密集(ji)式、結構(gou)緊湊。由于(yu)(yu)(yu)整體短(duan)而密集(ji),故穩定(ding)性好,安裝無需支(zhi)架。 組合式法(fa)蘭加熱(re)器大(da)多采(cai)用氬弧焊接(jie)方式使(shi)電(dian)(dian)熱(re)管(guan)于(yu)(yu)(yu)法(fa)蘭連接(jie),也可利用緊固裝置的形(xing)式,即每支(zhi)電(dian)(dian)熱(re)管(guan)上焊由緊固件。然后(hou)(hou)與法(fa)蘭蓋采(cai)用螺母鎖緊。管(guan)子于(yu)(yu)(yu)緊固件采(cai)用氬弧焊接(jie),永(yong)不泄漏(lou)。緊固件密封處采(cai)用科(ke)學(xue)的工(gong)(gong)藝。單支(zhi)更換極為方便,大(da)大(da)節約以(yi)后(hou)(hou)的維修成(cheng)本 選(xuan)擇進口及國內優質材料。科(ke)學(xue)的生產(chan)工(gong)(gong)藝,嚴(yan)格的質量管(guan)理,保證電(dian)(dian)熱(re)管(guan)優越(yue)的電(dian)(dian)氣(qi)性能。
防爆法蘭電熱器概述及工作原理
法蘭(lan)加(jia)熱(re)(re)(re)(re)(re)器:是采(cai)用U型管狀(zhuang)電熱(re)(re)(re)(re)(re)元(yuan)(yuan)(yuan)件(jian)(jian),依據加(jia)熱(re)(re)(re)(re)(re)不(bu)同介(jie)質設計(ji)規(gui)范,按照功率配置要(yao)求裝配在法蘭(lan)蓋上,插入需(xu)加(jia)熱(re)(re)(re)(re)(re)物料中,發(fa)熱(re)(re)(re)(re)(re)元(yuan)(yuan)(yuan)件(jian)(jian)工(gong)作時(shi)所發(fa)出(chu)(chu)的大量熱(re)(re)(re)(re)(re)量傳導給被(bei)加(jia)熱(re)(re)(re)(re)(re)介(jie)質使(shi)介(jie)質溫度升高,達(da)到(dao)所需(xu)的工(gong)藝要(yao)求。當介(jie)質溫度達(da)到(dao)工(gong)藝要(yao)求的設定值時(shi),控制(zhi)系統根據溫度傳感器信(xin)號,經PID 運算后調節電加(jia)熱(re)(re)(re)(re)(re)器輸出(chu)(chu)功率,對發(fa)熱(re)(re)(re)(re)(re)元(yuan)(yuan)(yuan)件(jian)(jian)的電阻(zu)性負載實現溫度控制(zhi)。使(shi)介(jie)質溫度均勻,達(da)到(dao)所需(xu)要(yao)求;當發(fa)熱(re)(re)(re)(re)(re)元(yuan)(yuan)(yuan)件(jian)(jian)超溫或低液位時(shi),發(fa)熱(re)(re)(re)(re)(re)元(yuan)(yuan)(yuan)件(jian)(jian)的聯鎖保護(hu)裝置立即切斷加(jia)熱(re)(re)(re)(re)(re)電源避免發(fa)熱(re)(re)(re)(re)(re)元(yuan)(yuan)(yuan)件(jian)(jian)燒(shao)壞,延長(chang)使(shi)用壽命。
