防爆法蘭電熱器性能及使用
法(fa)蘭加熱器是由(you)多支加熱管(guan)焊接在法(fa)蘭上集(ji)中(zhong)加熱。主要(yao)用于敞開式、封閉式的溶液箱(xiang)和循環(huan)系統中(zhong)加熱用。
防爆法蘭電熱器優點
防爆法(fa)蘭電(dian)(dian)熱管(guan)表面功率大(da)(da)(da),使空氣(qi)加熱表面負荷(he)的(de)(de)2~4倍,高度密集式、結構緊(jin)湊。由于(yu)整(zheng)體短而密集,故穩定性(xing)好,安裝(zhuang)無需支架。 組合式法(fa)蘭加熱器大(da)(da)(da)多采(cai)用(yong)(yong)氬(ya)弧焊(han)(han)接(jie)(jie)方(fang)式使電(dian)(dian)熱管(guan)于(yu)法(fa)蘭連接(jie)(jie),也可利(li)用(yong)(yong)緊(jin)固(gu)裝(zhuang)置的(de)(de)形(xing)式,即每支電(dian)(dian)熱管(guan)上(shang)焊(han)(han)由緊(jin)固(gu)件(jian)(jian)。然后與法(fa)蘭蓋(gai)采(cai)用(yong)(yong)螺(luo)母鎖緊(jin)。管(guan)子于(yu)緊(jin)固(gu)件(jian)(jian)采(cai)用(yong)(yong)氬(ya)弧焊(han)(han)接(jie)(jie),永不泄(xie)漏。緊(jin)固(gu)件(jian)(jian)密封處采(cai)用(yong)(yong)科學的(de)(de)工藝。單支更換極(ji)為方(fang)便,大(da)(da)(da)大(da)(da)(da)節(jie)約以(yi)后的(de)(de)維修成本 選(xuan)擇進口(kou)及(ji)國內優質(zhi)材料。科學的(de)(de)生產工藝,嚴格(ge)的(de)(de)質(zhi)量管(guan)理,保證電(dian)(dian)熱管(guan)優越的(de)(de)電(dian)(dian)氣(qi)性(xing)能。
防爆法蘭電熱器概述及工作原理
法(fa)(fa)蘭加(jia)(jia)熱(re)(re)(re)(re)器(qi):是采用U型管狀電(dian)熱(re)(re)(re)(re)元(yuan)件(jian)(jian),依據(ju)加(jia)(jia)熱(re)(re)(re)(re)不同介質(zhi)(zhi)設(she)計(ji)規(gui)范,按照(zhao)功率配置要(yao)求裝配在法(fa)(fa)蘭蓋上,插入(ru)需加(jia)(jia)熱(re)(re)(re)(re)物料(liao)中,發(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)工作(zuo)時所(suo)(suo)發(fa)出(chu)的大(da)量(liang)熱(re)(re)(re)(re)量(liang)傳(chuan)(chuan)導給(gei)被(bei)加(jia)(jia)熱(re)(re)(re)(re)介質(zhi)(zhi)使介質(zhi)(zhi)溫(wen)(wen)(wen)(wen)度(du)升高,達(da)到所(suo)(suo)需的工藝要(yao)求。當介質(zhi)(zhi)溫(wen)(wen)(wen)(wen)度(du)達(da)到工藝要(yao)求的設(she)定(ding)值(zhi)時,控制系統根據(ju)溫(wen)(wen)(wen)(wen)度(du)傳(chuan)(chuan)感器(qi)信號,經(jing)PID 運算后調(diao)節電(dian)加(jia)(jia)熱(re)(re)(re)(re)器(qi)輸出(chu)功率,對發(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)的電(dian)阻性負載實現溫(wen)(wen)(wen)(wen)度(du)控制。使介質(zhi)(zhi)溫(wen)(wen)(wen)(wen)度(du)均勻,達(da)到所(suo)(suo)需要(yao)求;當發(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)超溫(wen)(wen)(wen)(wen)或低液位時,發(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)的聯鎖(suo)保(bao)護裝置立(li)即切(qie)斷加(jia)(jia)熱(re)(re)(re)(re)電(dian)源(yuan)避免發(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)燒壞,延長(chang)使用壽命。
