防爆法蘭電熱器性能及使用
法蘭(lan)加(jia)熱器是由多支加(jia)熱管焊(han)接在法蘭(lan)上集中加(jia)熱。主要用于敞開式(shi)、封閉式(shi)的溶液(ye)箱和循環系統中加(jia)熱用。
防爆法蘭電熱器優點
防爆法蘭(lan)(lan)電(dian)熱(re)管表面(mian)(mian)功率大(da)(da),使(shi)空(kong)氣(qi)加(jia)熱(re)表面(mian)(mian)負荷的2~4倍,高度密集(ji)式、結構(gou)緊(jin)湊(cou)。由于整(zheng)體短(duan)而密集(ji),故穩定(ding)性好,安裝(zhuang)無(wu)需支架。 組合式法蘭(lan)(lan)加(jia)熱(re)器大(da)(da)多采用氬弧(hu)焊(han)接(jie)(jie)方式使(shi)電(dian)熱(re)管于法蘭(lan)(lan)連接(jie)(jie),也可利用緊(jin)固(gu)裝(zhuang)置(zhi)的形式,即每支電(dian)熱(re)管上焊(han)由緊(jin)固(gu)件(jian)。然后(hou)與法蘭(lan)(lan)蓋采用螺(luo)母鎖緊(jin)。管子于緊(jin)固(gu)件(jian)采用氬弧(hu)焊(han)接(jie)(jie),永不(bu)泄漏(lou)。緊(jin)固(gu)件(jian)密封處采用科學的工(gong)藝。單(dan)支更換極為方便,大(da)(da)大(da)(da)節(jie)約以(yi)后(hou)的維修(xiu)成本 選擇進口及(ji)國內(nei)優質(zhi)材料。科學的生產工(gong)藝,嚴格的質(zhi)量(liang)管理,保證(zheng)電(dian)熱(re)管優越的電(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)器:是(shi)采用(yong)U型(xing)管狀電(dian)(dian)(dian)熱(re)(re)(re)元(yuan)件(jian)(jian)(jian),依據加(jia)熱(re)(re)(re)不同介(jie)質(zhi)(zhi)設計規范(fan),按(an)照功率配置要(yao)求(qiu)裝配在法蘭(lan)蓋(gai)上,插入需加(jia)熱(re)(re)(re)物料中,發(fa)熱(re)(re)(re)元(yuan)件(jian)(jian)(jian)工(gong)(gong)作時所發(fa)出的(de)大(da)量熱(re)(re)(re)量傳導給(gei)被加(jia)熱(re)(re)(re)介(jie)質(zhi)(zhi)使(shi)(shi)介(jie)質(zhi)(zhi)溫(wen)(wen)度升高,達(da)到(dao)所需的(de)工(gong)(gong)藝要(yao)求(qiu)。當(dang)介(jie)質(zhi)(zhi)溫(wen)(wen)度達(da)到(dao)工(gong)(gong)藝要(yao)求(qiu)的(de)設定(ding)值時,控(kong)制(zhi)系統根據溫(wen)(wen)度傳感器信號,經(jing)PID 運算(suan)后調節(jie)電(dian)(dian)(dian)加(jia)熱(re)(re)(re)器輸出功率,對發(fa)熱(re)(re)(re)元(yuan)件(jian)(jian)(jian)的(de)電(dian)(dian)(dian)阻性負載實現溫(wen)(wen)度控(kong)制(zhi)。使(shi)(shi)介(jie)質(zhi)(zhi)溫(wen)(wen)度均勻,達(da)到(dao)所需要(yao)求(qiu);當(dang)發(fa)熱(re)(re)(re)元(yuan)件(jian)(jian)(jian)超溫(wen)(wen)或低液(ye)位(wei)時,發(fa)熱(re)(re)(re)元(yuan)件(jian)(jian)(jian)的(de)聯鎖保護裝置立即切斷(duan)加(jia)熱(re)(re)(re)電(dian)(dian)(dian)源避(bi)免發(fa)熱(re)(re)(re)元(yuan)件(jian)(jian)(jian)燒壞,延長使(shi)(shi)用(yong)壽命。
