防爆法蘭電熱器性能及使用
法(fa)蘭(lan)(lan)加(jia)熱器是由多支加(jia)熱管焊接在法(fa)蘭(lan)(lan)上(shang)集中(zhong)加(jia)熱。主要用于敞(chang)開式、封閉(bi)式的溶(rong)液箱和循環系(xi)統(tong)中(zhong)加(jia)熱用。
防爆法蘭電熱器優點
防爆法(fa)蘭(lan)電(dian)(dian)熱管(guan)(guan)(guan)(guan)表面功率大(da),使(shi)空氣(qi)加熱表面負荷的(de)2~4倍,高度密(mi)集式、結構緊(jin)湊。由(you)于(yu)整體短(duan)而密(mi)集,故穩定性(xing)好,安裝無需(xu)支架。 組合式法(fa)蘭(lan)加熱器大(da)多采用(yong)氬(ya)弧(hu)焊(han)接(jie)(jie)(jie)方(fang)式使(shi)電(dian)(dian)熱管(guan)(guan)(guan)(guan)于(yu)法(fa)蘭(lan)連接(jie)(jie)(jie),也可(ke)利用(yong)緊(jin)固(gu)(gu)裝置(zhi)的(de)形(xing)式,即每支電(dian)(dian)熱管(guan)(guan)(guan)(guan)上焊(han)由(you)緊(jin)固(gu)(gu)件(jian)。然(ran)后與法(fa)蘭(lan)蓋采用(yong)螺母(mu)鎖緊(jin)。管(guan)(guan)(guan)(guan)子于(yu)緊(jin)固(gu)(gu)件(jian)采用(yong)氬(ya)弧(hu)焊(han)接(jie)(jie)(jie),永不泄漏。緊(jin)固(gu)(gu)件(jian)密(mi)封(feng)處采用(yong)科(ke)學的(de)工藝。單支更換(huan)極為方(fang)便,大(da)大(da)節約(yue)以后的(de)維修(xiu)成(cheng)本 選擇進口及國(guo)內優質材料(liao)。科(ke)學的(de)生(sheng)產工藝,嚴格的(de)質量管(guan)(guan)(guan)(guan)理,保證電(dian)(dian)熱管(guan)(guan)(guan)(guan)優越(yue)的(de)電(dian)(dian)氣(qi)性(xing)能。
防爆法蘭電熱器概述及工作原理
法蘭(lan)加(jia)熱(re)器(qi):是(shi)采用(yong)(yong)U型管狀電(dian)(dian)熱(re)元件,依據加(jia)熱(re)不同介(jie)質(zhi)(zhi)設計規范,按照(zhao)功率(lv)配(pei)置要(yao)求(qiu)(qiu)裝配(pei)在法蘭(lan)蓋上,插(cha)入需加(jia)熱(re)物(wu)料中,發熱(re)元件工(gong)作時(shi)所(suo)發出(chu)的(de)(de)大量熱(re)量傳導給被加(jia)熱(re)介(jie)質(zhi)(zhi)使介(jie)質(zhi)(zhi)溫(wen)(wen)(wen)度(du)升高,達到(dao)所(suo)需的(de)(de)工(gong)藝要(yao)求(qiu)(qiu)。當介(jie)質(zhi)(zhi)溫(wen)(wen)(wen)度(du)達到(dao)工(gong)藝要(yao)求(qiu)(qiu)的(de)(de)設定值時(shi),控(kong)制(zhi)(zhi)系(xi)統根(gen)據溫(wen)(wen)(wen)度(du)傳感(gan)器(qi)信(xin)號,經(jing)PID 運(yun)算后調節電(dian)(dian)加(jia)熱(re)器(qi)輸出(chu)功率(lv),對(dui)發熱(re)元件的(de)(de)電(dian)(dian)阻性負(fu)載(zai)實現溫(wen)(wen)(wen)度(du)控(kong)制(zhi)(zhi)。使介(jie)質(zhi)(zhi)溫(wen)(wen)(wen)度(du)均勻,達到(dao)所(suo)需要(yao)求(qiu)(qiu);當發熱(re)元件超溫(wen)(wen)(wen)或低液位時(shi),發熱(re)元件的(de)(de)聯鎖(suo)保護裝置立即切斷加(jia)熱(re)電(dian)(dian)源避免發熱(re)元件燒壞,延長(chang)使用(yong)(yong)壽命。
