法蘭電加熱管也稱插入式電加熱器
法蘭電加熱管性能及使用
法(fa)蘭加(jia)熱器是由多支加(jia)熱管焊接在法(fa)蘭上集中(zhong)加(jia)熱。主要用于敞開式、封閉式的(de)溶(rong)液箱(xiang)和循環系(xi)統中(zhong)加(jia)熱用。
法蘭電加熱管優點
表(biao)(biao)面功率(lv)大,使空氣加(jia)(jia)熱(re)(re)表(biao)(biao)面負荷的(de)(de)2~4倍(bei),高(gao)度(du)密集式(shi)(shi)、結構緊湊。由于整(zheng)體短而密集,法(fa)(fa)(fa)蘭電(dian)加(jia)(jia)熱(re)(re)管(guan)故穩(wen)定性好,安裝無需支(zhi)架。 組合式(shi)(shi)法(fa)(fa)(fa)蘭加(jia)(jia)熱(re)(re)器大多(duo)采用(yong)(yong)(yong)氬(ya)弧焊(han)接(jie)方式(shi)(shi)使電(dian)熱(re)(re)管(guan)于法(fa)(fa)(fa)蘭連接(jie),也可利用(yong)(yong)(yong)緊固裝置(zhi)的(de)(de)形式(shi)(shi),即(ji)每(mei)支(zhi)電(dian)熱(re)(re)管(guan)上焊(han)由緊固件(jian)。然后與(yu)法(fa)(fa)(fa)蘭蓋采用(yong)(yong)(yong)螺母(mu)鎖緊。管(guan)子于緊固件(jian)采用(yong)(yong)(yong)氬(ya)弧焊(han)接(jie),永(yong)不(bu)泄漏。緊固件(jian)密封處采用(yong)(yong)(yong)科學(xue)(xue)的(de)(de)工藝。單支(zhi)更換極為方便,大大節約以后的(de)(de)維(wei)修成本(ben) 選擇(ze)進口及國(guo)內(nei)優(you)質(zhi)材料。科學(xue)(xue)的(de)(de)生產工藝,嚴(yan)格(ge)的(de)(de)質(zhi)量管(guan)理,保證電(dian)熱(re)(re)管(guan)優(you)越的(de)(de)電(dian)氣性能。
法蘭電加熱管概述及工(gong)作原理
法(fa)蘭加(jia)(jia)熱(re)(re)(re)(re)器:是采(cai)用(yong)U型管狀電(dian)熱(re)(re)(re)(re)元(yuan)件(jian)(jian),依據加(jia)(jia)熱(re)(re)(re)(re)不同介(jie)(jie)質(zhi)(zhi)設計(ji)規范,按照功率配置要(yao)求裝(zhuang)配在法(fa)蘭蓋上,插入需(xu)加(jia)(jia)熱(re)(re)(re)(re)物料中,發(fa)(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)工(gong)(gong)作時所(suo)發(fa)(fa)出的大(da)量(liang)熱(re)(re)(re)(re)量(liang)傳導給被(bei)加(jia)(jia)熱(re)(re)(re)(re)介(jie)(jie)質(zhi)(zhi)使(shi)介(jie)(jie)質(zhi)(zhi)溫(wen)(wen)度(du)(du)升高,達(da)到所(suo)需(xu)的工(gong)(gong)藝要(yao)求。當(dang)介(jie)(jie)質(zhi)(zhi)溫(wen)(wen)度(du)(du)達(da)到工(gong)(gong)藝要(yao)求的設定值時,控(kong)制(zhi)系統(tong)根據溫(wen)(wen)度(du)(du)傳感器信號,經PID 運算后調(diao)節(jie)電(dian)加(jia)(jia)熱(re)(re)(re)(re)器輸(shu)出功率,對發(fa)(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)的電(dian)阻性(xing)負載實現(xian)溫(wen)(wen)度(du)(du)控(kong)制(zhi)。使(shi)介(jie)(jie)質(zhi)(zhi)溫(wen)(wen)度(du)(du)均勻,達(da)到所(suo)需(xu)要(yao)求;當(dang)發(fa)(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)超(chao)溫(wen)(wen)或低液位時,發(fa)(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)的聯(lian)鎖保護裝(zhuang)置立即(ji)切斷加(jia)(jia)熱(re)(re)(re)(re)電(dian)源(yuan)避免發(fa)(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)燒壞(huai),延(yan)長(chang)使(shi)用(yong)壽命(ming)。
