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)蘭(lan)加(jia)熱(re)(re)(re)器是(shi)由多支(zhi)加(jia)熱(re)(re)(re)管焊接在法(fa)蘭(lan)上集中加(jia)熱(re)(re)(re)。主要用于敞開式(shi)、封閉(bi)式(shi)的溶液箱和循(xun)環系(xi)統中加(jia)熱(re)(re)(re)用。
法蘭電加熱管優點
表面功率大,使(shi)空氣加(jia)熱(re)(re)(re)表面負荷的2~4倍,高度(du)密集式、結構緊(jin)(jin)(jin)湊。由于整體短而密集,法(fa)蘭電(dian)(dian)加(jia)熱(re)(re)(re)管故(gu)穩定(ding)性(xing)好,安裝無需支(zhi)(zhi)架。 組合式法(fa)蘭加(jia)熱(re)(re)(re)器大多(duo)采用(yong)(yong)(yong)氬(ya)(ya)弧(hu)焊接方式使(shi)電(dian)(dian)熱(re)(re)(re)管于法(fa)蘭連(lian)接,也可利(li)用(yong)(yong)(yong)緊(jin)(jin)(jin)固(gu)裝置的形式,即每支(zhi)(zhi)電(dian)(dian)熱(re)(re)(re)管上焊由緊(jin)(jin)(jin)固(gu)件。然后與法(fa)蘭蓋采用(yong)(yong)(yong)螺母(mu)鎖緊(jin)(jin)(jin)。管子于緊(jin)(jin)(jin)固(gu)件采用(yong)(yong)(yong)氬(ya)(ya)弧(hu)焊接,永不泄漏。緊(jin)(jin)(jin)固(gu)件密封處采用(yong)(yong)(yong)科(ke)學的工藝。單支(zhi)(zhi)更(geng)換極為方便,大大節約以(yi)后的維修(xiu)成本 選擇進口及國內優質材(cai)料。科(ke)學的生產(chan)工藝,嚴格的質量管理,保證電(dian)(dian)熱(re)(re)(re)管優越的電(dian)(dian)氣性(xing)能。
法蘭電(dian)加熱(re)管概(gai)述(shu)及工作原理
法(fa)蘭(lan)加(jia)(jia)熱(re)(re)(re)(re)器:是采用(yong)U型(xing)管(guan)狀電(dian)熱(re)(re)(re)(re)元(yuan)件,依據加(jia)(jia)熱(re)(re)(re)(re)不同(tong)介(jie)質(zhi)設(she)計(ji)規范(fan),按照功率配置要(yao)(yao)求(qiu)裝配在法(fa)蘭(lan)蓋上(shang),插入(ru)需(xu)加(jia)(jia)熱(re)(re)(re)(re)物料中,發(fa)(fa)熱(re)(re)(re)(re)元(yuan)件工(gong)作時所(suo)發(fa)(fa)出的大量熱(re)(re)(re)(re)量傳導(dao)給被加(jia)(jia)熱(re)(re)(re)(re)介(jie)質(zhi)使介(jie)質(zhi)溫(wen)度(du)(du)(du)升高(gao),達(da)到所(suo)需(xu)的工(gong)藝(yi)要(yao)(yao)求(qiu)。當介(jie)質(zhi)溫(wen)度(du)(du)(du)達(da)到工(gong)藝(yi)要(yao)(yao)求(qiu)的設(she)定值時,控制系(xi)統根據溫(wen)度(du)(du)(du)傳感器信號,經PID 運(yun)算后調節電(dian)加(jia)(jia)熱(re)(re)(re)(re)器輸出功率,對(dui)發(fa)(fa)熱(re)(re)(re)(re)元(yuan)件的電(dian)阻性負載(zai)實現(xian)溫(wen)度(du)(du)(du)控制。使介(jie)質(zhi)溫(wen)度(du)(du)(du)均勻,達(da)到所(suo)需(xu)要(yao)(yao)求(qiu);當發(fa)(fa)熱(re)(re)(re)(re)元(yuan)件超(chao)溫(wen)或低液位(wei)時,發(fa)(fa)熱(re)(re)(re)(re)元(yuan)件的聯鎖保(bao)護裝置立(li)即切斷加(jia)(jia)熱(re)(re)(re)(re)電(dian)源避(bi)免(mian)發(fa)(fa)熱(re)(re)(re)(re)元(yuan)件燒(shao)壞,延長使用(yong)壽命(ming)。
