防爆法蘭電熱器性能及使用
法蘭(lan)加(jia)熱(re)器(qi)是由多支(zhi)加(jia)熱(re)管焊接在法蘭(lan)上集中加(jia)熱(re)。主要用于敞開式、封閉式的溶液箱和(he)循環(huan)系統中加(jia)熱(re)用。
防爆法蘭電熱器優點
防(fang)爆法(fa)蘭(lan)電(dian)(dian)(dian)熱(re)管(guan)(guan)表面(mian)功率大,使空氣(qi)加熱(re)表面(mian)負荷的(de)2~4倍(bei),高度密(mi)集(ji)式(shi)(shi)、結(jie)構緊(jin)湊(cou)。由(you)于整(zheng)體(ti)短而密(mi)集(ji),故穩定性(xing)(xing)好,安裝(zhuang)無需支(zhi)架。 組合式(shi)(shi)法(fa)蘭(lan)加熱(re)器大多采(cai)(cai)用(yong)(yong)氬弧焊(han)接方(fang)(fang)式(shi)(shi)使電(dian)(dian)(dian)熱(re)管(guan)(guan)于法(fa)蘭(lan)連接,也可利用(yong)(yong)緊(jin)固(gu)(gu)裝(zhuang)置的(de)形式(shi)(shi),即每支(zhi)電(dian)(dian)(dian)熱(re)管(guan)(guan)上焊(han)由(you)緊(jin)固(gu)(gu)件。然(ran)后(hou)與法(fa)蘭(lan)蓋采(cai)(cai)用(yong)(yong)螺母鎖緊(jin)。管(guan)(guan)子(zi)于緊(jin)固(gu)(gu)件采(cai)(cai)用(yong)(yong)氬弧焊(han)接,永不(bu)泄漏(lou)。緊(jin)固(gu)(gu)件密(mi)封處采(cai)(cai)用(yong)(yong)科學的(de)工(gong)藝(yi)。單支(zhi)更換(huan)極為方(fang)(fang)便,大大節約以后(hou)的(de)維修成本(ben) 選(xuan)擇進口及國內優(you)質材(cai)料。科學的(de)生產工(gong)藝(yi),嚴格的(de)質量管(guan)(guan)理,保證(zheng)電(dian)(dian)(dian)熱(re)管(guan)(guan)優(you)越的(de)電(dian)(dian)(dian)氣(qi)性(xing)(xing)能。
防爆法蘭電熱器概述及工作原理
法蘭加熱(re)(re)(re)器(qi)(qi):是采(cai)用U型管狀(zhuang)電(dian)熱(re)(re)(re)元(yuan)件,依(yi)據加熱(re)(re)(re)不同介(jie)質(zhi)(zhi)設(she)(she)計規范(fan),按照功率配置要(yao)求裝(zhuang)配在法蘭蓋上,插入需加熱(re)(re)(re)物料中(zhong),發(fa)熱(re)(re)(re)元(yuan)件工作(zuo)時所發(fa)出的大量熱(re)(re)(re)量傳(chuan)導給被(bei)加熱(re)(re)(re)介(jie)質(zhi)(zhi)使(shi)介(jie)質(zhi)(zhi)溫(wen)度(du)升高(gao),達到所需的工藝要(yao)求。當介(jie)質(zhi)(zhi)溫(wen)度(du)達到工藝要(yao)求的設(she)(she)定值時,控(kong)制(zhi)系統根據溫(wen)度(du)傳(chuan)感(gan)器(qi)(qi)信(xin)號,經PID 運算后調(diao)節電(dian)加熱(re)(re)(re)器(qi)(qi)輸(shu)出功率,對發(fa)熱(re)(re)(re)元(yuan)件的電(dian)阻性負載(zai)實(shi)現溫(wen)度(du)控(kong)制(zhi)。使(shi)介(jie)質(zhi)(zhi)溫(wen)度(du)均勻,達到所需要(yao)求;當發(fa)熱(re)(re)(re)元(yuan)件超溫(wen)或低液位時,發(fa)熱(re)(re)(re)元(yuan)件的聯鎖(suo)保護(hu)裝(zhuang)置立(li)即切(qie)斷加熱(re)(re)(re)電(dian)源避免發(fa)熱(re)(re)(re)元(yuan)件燒壞,延長使(shi)用壽(shou)命。
