防爆法蘭電熱器性能及使用
法蘭加熱(re)器(qi)是由多支(zhi)加熱(re)管焊接在法蘭上集中加熱(re)。主(zhu)要用(yong)于敞開式、封閉式的溶液箱和循(xun)環(huan)系統(tong)中加熱(re)用(yong)。
防爆法蘭電熱器優點
防(fang)爆(bao)法(fa)(fa)蘭(lan)電(dian)熱(re)管表面功率大(da),使(shi)空氣加(jia)熱(re)表面負(fu)荷的2~4倍,高度密集式(shi)(shi)、結構緊(jin)(jin)湊。由于整體短(duan)而(er)密集,故穩(wen)定性好,安裝無需支(zhi)架。 組合式(shi)(shi)法(fa)(fa)蘭(lan)加(jia)熱(re)器(qi)大(da)多采用(yong)(yong)(yong)氬弧焊接(jie)方式(shi)(shi)使(shi)電(dian)熱(re)管于法(fa)(fa)蘭(lan)連接(jie),也可(ke)利用(yong)(yong)(yong)緊(jin)(jin)固(gu)(gu)裝置的形(xing)式(shi)(shi),即每支(zhi)電(dian)熱(re)管上焊由緊(jin)(jin)固(gu)(gu)件。然后與法(fa)(fa)蘭(lan)蓋采用(yong)(yong)(yong)螺母鎖緊(jin)(jin)。管子(zi)于緊(jin)(jin)固(gu)(gu)件采用(yong)(yong)(yong)氬弧焊接(jie),永不(bu)泄(xie)漏。緊(jin)(jin)固(gu)(gu)件密封處采用(yong)(yong)(yong)科(ke)學的工(gong)藝。單支(zhi)更換極為(wei)方便,大(da)大(da)節約以后的維(wei)修(xiu)成本 選擇進口及國內優(you)質材(cai)料。科(ke)學的生產(chan)工(gong)藝,嚴格(ge)的質量管理,保證電(dian)熱(re)管優(you)越的電(dian)氣性能。
防爆法蘭電熱器概述及工作原理
法蘭(lan)加(jia)熱(re)(re)(re)器:是采用U型管狀電(dian)(dian)熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)件,依據加(jia)熱(re)(re)(re)不同(tong)介質(zhi)設(she)計規范,按照功率配置要(yao)求裝(zhuang)配在法蘭(lan)蓋上,插入需(xu)加(jia)熱(re)(re)(re)物料中(zhong),發熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)件工作時所(suo)發出的(de)大量熱(re)(re)(re)量傳導給(gei)被加(jia)熱(re)(re)(re)介質(zhi)使(shi)介質(zhi)溫(wen)度升(sheng)高(gao),達到所(suo)需(xu)的(de)工藝(yi)要(yao)求。當介質(zhi)溫(wen)度達到工藝(yi)要(yao)求的(de)設(she)定值時,控(kong)制(zhi)系(xi)統根據溫(wen)度傳感(gan)器信號(hao),經(jing)PID 運算后調節電(dian)(dian)加(jia)熱(re)(re)(re)器輸出功率,對(dui)發熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)件的(de)電(dian)(dian)阻性負載實現(xian)溫(wen)度控(kong)制(zhi)。使(shi)介質(zhi)溫(wen)度均勻,達到所(suo)需(xu)要(yao)求;當發熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)件超溫(wen)或低液位時,發熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)件的(de)聯鎖保護裝(zhuang)置立即切斷加(jia)熱(re)(re)(re)電(dian)(dian)源避免發熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)件燒壞,延長使(shi)用壽命。
