防爆法蘭電熱器性能及使用
法蘭加熱器是由多支加熱管焊接在法蘭上集(ji)中(zhong)加熱。主要用(yong)于(yu)敞開式、封閉式的溶液箱(xiang)和循環系統中(zhong)加熱用(yong)。
防爆法蘭電熱器優點
防爆法蘭電(dian)熱(re)(re)(re)管表(biao)面(mian)功率大,使(shi)空氣加(jia)(jia)熱(re)(re)(re)表(biao)面(mian)負荷(he)的(de)2~4倍,高度密(mi)集式(shi)(shi)、結構緊(jin)(jin)湊。由于整體短而密(mi)集,故(gu)穩定性好,安裝無需支(zhi)架。 組合式(shi)(shi)法蘭加(jia)(jia)熱(re)(re)(re)器大多采用氬弧(hu)焊接(jie)方式(shi)(shi)使(shi)電(dian)熱(re)(re)(re)管于法蘭連接(jie),也可利用緊(jin)(jin)固裝置的(de)形式(shi)(shi),即每支(zhi)電(dian)熱(re)(re)(re)管上(shang)焊由緊(jin)(jin)固件。然后(hou)與法蘭蓋采用螺母(mu)鎖緊(jin)(jin)。管子于緊(jin)(jin)固件采用氬弧(hu)焊接(jie),永不泄(xie)漏(lou)。緊(jin)(jin)固件密(mi)封處采用科學的(de)工藝。單支(zhi)更(geng)換極為方便,大大節(jie)約以(yi)后(hou)的(de)維修成本 選擇進口及國(guo)內優(you)質材料。科學的(de)生產工藝,嚴(yan)格的(de)質量管理,保證電(dian)熱(re)(re)(re)管優(you)越的(de)電(dian)氣性能。
防爆法蘭電熱器概述及工作原理
法蘭加(jia)(jia)熱(re)(re)(re)(re)器:是(shi)采(cai)用(yong)(yong)U型管狀電(dian)熱(re)(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)件(jian)(jian),依據加(jia)(jia)熱(re)(re)(re)(re)不同介(jie)質(zhi)(zhi)設(she)計(ji)規范,按照(zhao)功率(lv)配置要(yao)(yao)求裝配在法蘭蓋上,插入需(xu)(xu)加(jia)(jia)熱(re)(re)(re)(re)物料中(zhong),發(fa)熱(re)(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)件(jian)(jian)工(gong)作時所(suo)發(fa)出的大量(liang)熱(re)(re)(re)(re)量(liang)傳導(dao)給(gei)被加(jia)(jia)熱(re)(re)(re)(re)介(jie)質(zhi)(zhi)使(shi)介(jie)質(zhi)(zhi)溫(wen)度升高,達到(dao)(dao)所(suo)需(xu)(xu)的工(gong)藝(yi)要(yao)(yao)求。當介(jie)質(zhi)(zhi)溫(wen)度達到(dao)(dao)工(gong)藝(yi)要(yao)(yao)求的設(she)定值時,控(kong)制系統根據溫(wen)度傳感器信號,經PID 運算(suan)后調節電(dian)加(jia)(jia)熱(re)(re)(re)(re)器輸(shu)出功率(lv),對發(fa)熱(re)(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)件(jian)(jian)的電(dian)阻性負載實現(xian)溫(wen)度控(kong)制。使(shi)介(jie)質(zhi)(zhi)溫(wen)度均勻,達到(dao)(dao)所(suo)需(xu)(xu)要(yao)(yao)求;當發(fa)熱(re)(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)件(jian)(jian)超溫(wen)或低(di)液(ye)位時,發(fa)熱(re)(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)件(jian)(jian)的聯鎖(suo)保護裝置立即(ji)切斷(duan)加(jia)(jia)熱(re)(re)(re)(re)電(dian)源避免(mian)發(fa)熱(re)(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)件(jian)(jian)燒(shao)壞(huai),延長使(shi)用(yong)(yong)壽命。
