防爆法蘭電熱器性能及使用
法蘭加熱器是(shi)由(you)多支加熱管焊接在法蘭上集(ji)中(zhong)(zhong)加熱。主(zhu)要(yao)用(yong)于敞(chang)開式、封閉式的(de)溶(rong)液箱和循環系統(tong)中(zhong)(zhong)加熱用(yong)。
防爆法蘭電熱器優點
防(fang)爆法蘭(lan)電(dian)(dian)熱(re)管表(biao)面功率大(da)(da),使(shi)空(kong)氣(qi)加熱(re)表(biao)面負荷的(de)2~4倍(bei),高度密集(ji)式(shi)(shi)、結構緊(jin)湊。由于整體短而(er)密集(ji),故穩定性好,安(an)裝無需(xu)支架。 組(zu)合式(shi)(shi)法蘭(lan)加熱(re)器大(da)(da)多(duo)采用(yong)(yong)(yong)氬弧(hu)焊接(jie)方(fang)式(shi)(shi)使(shi)電(dian)(dian)熱(re)管于法蘭(lan)連接(jie),也可利用(yong)(yong)(yong)緊(jin)固(gu)(gu)裝置的(de)形(xing)式(shi)(shi),即每支電(dian)(dian)熱(re)管上焊由緊(jin)固(gu)(gu)件(jian)。然后與法蘭(lan)蓋采用(yong)(yong)(yong)螺母(mu)鎖緊(jin)。管子于緊(jin)固(gu)(gu)件(jian)采用(yong)(yong)(yong)氬弧(hu)焊接(jie),永不泄(xie)漏。緊(jin)固(gu)(gu)件(jian)密封處采用(yong)(yong)(yong)科學的(de)工藝(yi)。單支更換極為方(fang)便,大(da)(da)大(da)(da)節約以后的(de)維(wei)修成本 選擇進口及國內優質(zhi)材料。科學的(de)生產(chan)工藝(yi),嚴格的(de)質(zhi)量(liang)管理,保證電(dian)(dian)熱(re)管優越的(de)電(dian)(dian)氣(qi)性能。
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(qi):是采用(yong)U型管狀電熱(re)(re)(re)(re)(re)元(yuan)(yuan)(yuan)件(jian),依據加(jia)熱(re)(re)(re)(re)(re)不同介(jie)質(zhi)(zhi)(zhi)(zhi)設(she)計規范,按(an)照功率(lv)配置要求(qiu)裝配在法蘭蓋上,插入需(xu)加(jia)熱(re)(re)(re)(re)(re)物料中,發(fa)(fa)熱(re)(re)(re)(re)(re)元(yuan)(yuan)(yuan)件(jian)工(gong)作時(shi)所(suo)(suo)發(fa)(fa)出(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(zhi)(zhi)(zhi)(zhi)使(shi)介(jie)質(zhi)(zhi)(zhi)(zhi)溫(wen)度升(sheng)高(gao),達到(dao)所(suo)(suo)需(xu)的工(gong)藝要求(qiu)。當介(jie)質(zhi)(zhi)(zhi)(zhi)溫(wen)度達到(dao)工(gong)藝要求(qiu)的設(she)定值時(shi),控制系統根據溫(wen)度傳感(gan)器(qi)信(xin)號,經PID 運算(suan)后調節電加(jia)熱(re)(re)(re)(re)(re)器(qi)輸出(chu)功率(lv),對發(fa)(fa)熱(re)(re)(re)(re)(re)元(yuan)(yuan)(yuan)件(jian)的電阻(zu)性負載實現(xian)溫(wen)度控制。使(shi)介(jie)質(zhi)(zhi)(zhi)(zhi)溫(wen)度均勻,達到(dao)所(suo)(suo)需(xu)要求(qiu);當發(fa)(fa)熱(re)(re)(re)(re)(re)元(yuan)(yuan)(yuan)件(jian)超溫(wen)或低液位時(shi),發(fa)(fa)熱(re)(re)(re)(re)(re)元(yuan)(yuan)(yuan)件(jian)的聯(lian)鎖保護裝置立即切斷加(jia)熱(re)(re)(re)(re)(re)電源避免發(fa)(fa)熱(re)(re)(re)(re)(re)元(yuan)(yuan)(yuan)件(jian)燒壞,延長使(shi)用(yong)壽命。
