防爆法蘭電熱器性能及使用
法(fa)蘭(lan)加熱器是由多支加熱管焊接在法(fa)蘭(lan)上(shang)集中(zhong)加熱。主要用于敞開式、封(feng)閉式的溶液箱(xiang)和循環系統中(zhong)加熱用。
防爆法蘭電熱器優點
防爆法(fa)蘭電(dian)(dian)(dian)熱(re)(re)管表面功率大(da),使空氣(qi)加熱(re)(re)表面負荷的(de)(de)(de)2~4倍,高(gao)度密(mi)集(ji)式(shi)(shi)(shi)、結構緊(jin)(jin)(jin)湊。由(you)于(yu)(yu)整體短而(er)密(mi)集(ji),故穩定(ding)性好,安(an)裝(zhuang)無需支(zhi)(zhi)架(jia)。 組合式(shi)(shi)(shi)法(fa)蘭加熱(re)(re)器大(da)多采用(yong)氬弧焊(han)接(jie)方式(shi)(shi)(shi)使電(dian)(dian)(dian)熱(re)(re)管于(yu)(yu)法(fa)蘭連接(jie),也可利用(yong)緊(jin)(jin)(jin)固(gu)裝(zhuang)置的(de)(de)(de)形式(shi)(shi)(shi),即每(mei)支(zhi)(zhi)電(dian)(dian)(dian)熱(re)(re)管上(shang)焊(han)由(you)緊(jin)(jin)(jin)固(gu)件(jian)。然后(hou)與(yu)法(fa)蘭蓋采用(yong)螺母鎖緊(jin)(jin)(jin)。管子于(yu)(yu)緊(jin)(jin)(jin)固(gu)件(jian)采用(yong)氬弧焊(han)接(jie),永不泄漏。緊(jin)(jin)(jin)固(gu)件(jian)密(mi)封處采用(yong)科學的(de)(de)(de)工(gong)藝(yi)。單(dan)支(zhi)(zhi)更換極為方便,大(da)大(da)節約以(yi)后(hou)的(de)(de)(de)維修成本 選(xuan)擇進口及國內優質(zhi)材料。科學的(de)(de)(de)生產(chan)工(gong)藝(yi),嚴格的(de)(de)(de)質(zhi)量管理,保證電(dian)(dian)(dian)熱(re)(re)管優越的(de)(de)(de)電(dian)(dian)(dian)氣(qi)性能。
防爆法蘭電熱器概述及工作原理
法(fa)蘭加(jia)熱(re)(re)(re)(re)(re)器(qi):是采用U型管狀電(dian)(dian)(dian)熱(re)(re)(re)(re)(re)元件(jian)(jian)(jian),依據加(jia)熱(re)(re)(re)(re)(re)不同介(jie)質設(she)計(ji)規范,按照(zhao)功率配(pei)置(zhi)要求裝(zhuang)配(pei)在法(fa)蘭蓋(gai)上,插入(ru)需(xu)(xu)加(jia)熱(re)(re)(re)(re)(re)物(wu)料中,發(fa)(fa)熱(re)(re)(re)(re)(re)元件(jian)(jian)(jian)工(gong)作時(shi)所發(fa)(fa)出的(de)大(da)量熱(re)(re)(re)(re)(re)量傳導給被加(jia)熱(re)(re)(re)(re)(re)介(jie)質使(shi)(shi)介(jie)質溫(wen)度升高,達到所需(xu)(xu)的(de)工(gong)藝要求。當介(jie)質溫(wen)度達到工(gong)藝要求的(de)設(she)定(ding)值時(shi),控制系(xi)統根據溫(wen)度傳感(gan)器(qi)信號,經(jing)PID 運算后(hou)調節(jie)電(dian)(dian)(dian)加(jia)熱(re)(re)(re)(re)(re)器(qi)輸出功率,對發(fa)(fa)熱(re)(re)(re)(re)(re)元件(jian)(jian)(jian)的(de)電(dian)(dian)(dian)阻性負載實現溫(wen)度控制。使(shi)(shi)介(jie)質溫(wen)度均勻(yun),達到所需(xu)(xu)要求;當發(fa)(fa)熱(re)(re)(re)(re)(re)元件(jian)(jian)(jian)超溫(wen)或低液位(wei)時(shi),發(fa)(fa)熱(re)(re)(re)(re)(re)元件(jian)(jian)(jian)的(de)聯(lian)鎖保護(hu)裝(zhuang)置(zhi)立即切斷加(jia)熱(re)(re)(re)(re)(re)電(dian)(dian)(dian)源避免發(fa)(fa)熱(re)(re)(re)(re)(re)元件(jian)(jian)(jian)燒(shao)壞(huai),延長使(shi)(shi)用壽命。
