防爆法蘭電熱器性能及使用
法(fa)蘭(lan)加(jia)熱(re)器(qi)是由多支加(jia)熱(re)管焊接在法(fa)蘭(lan)上集中(zhong)加(jia)熱(re)。主(zhu)要用于敞開式(shi)、封閉式(shi)的溶液箱和循環系統(tong)中(zhong)加(jia)熱(re)用。
防爆法蘭電熱器優點
防爆法蘭(lan)(lan)電(dian)(dian)熱(re)(re)(re)(re)管(guan)表面(mian)功率大(da),使空氣(qi)加熱(re)(re)(re)(re)表面(mian)負荷的(de)2~4倍,高度密(mi)集式、結構緊(jin)(jin)湊。由(you)(you)于(yu)(yu)整體(ti)短而密(mi)集,故穩定性好,安裝(zhuang)無需支架(jia)。 組(zu)合(he)式法蘭(lan)(lan)加熱(re)(re)(re)(re)器(qi)大(da)多采(cai)(cai)用(yong)氬弧焊(han)(han)接(jie)方式使電(dian)(dian)熱(re)(re)(re)(re)管(guan)于(yu)(yu)法蘭(lan)(lan)連接(jie),也可利用(yong)緊(jin)(jin)固(gu)裝(zhuang)置的(de)形式,即每(mei)支電(dian)(dian)熱(re)(re)(re)(re)管(guan)上焊(han)(han)由(you)(you)緊(jin)(jin)固(gu)件。然后與(yu)法蘭(lan)(lan)蓋采(cai)(cai)用(yong)螺母鎖緊(jin)(jin)。管(guan)子于(yu)(yu)緊(jin)(jin)固(gu)件采(cai)(cai)用(yong)氬弧焊(han)(han)接(jie),永不(bu)泄漏。緊(jin)(jin)固(gu)件密(mi)封(feng)處采(cai)(cai)用(yong)科(ke)學的(de)工(gong)(gong)藝。單(dan)支更換極為(wei)方便,大(da)大(da)節約(yue)以后的(de)維(wei)修成本 選擇進(jin)口(kou)及國內優質材料。科(ke)學的(de)生產工(gong)(gong)藝,嚴格的(de)質量管(guan)理,保證(zheng)電(dian)(dian)熱(re)(re)(re)(re)管(guan)優越的(de)電(dian)(dian)氣(qi)性能。
防爆法蘭電熱器概述及工作原理
法蘭(lan)加(jia)(jia)(jia)(jia)熱器:是采用(yong)U型管狀電(dian)熱元件(jian),依據(ju)加(jia)(jia)(jia)(jia)熱不同介質設計規范,按照功率配置(zhi)要(yao)(yao)求裝配在(zai)法蘭(lan)蓋上,插入需加(jia)(jia)(jia)(jia)熱物料中,發(fa)熱元件(jian)工(gong)(gong)作時所(suo)發(fa)出(chu)的(de)(de)(de)大量(liang)熱量(liang)傳(chuan)(chuan)導(dao)給被加(jia)(jia)(jia)(jia)熱介質使介質溫(wen)度(du)(du)(du)升高,達到(dao)所(suo)需的(de)(de)(de)工(gong)(gong)藝(yi)要(yao)(yao)求。當介質溫(wen)度(du)(du)(du)達到(dao)工(gong)(gong)藝(yi)要(yao)(yao)求的(de)(de)(de)設定值(zhi)時,控制(zhi)系統(tong)根據(ju)溫(wen)度(du)(du)(du)傳(chuan)(chuan)感器信號,經PID 運算后調節電(dian)加(jia)(jia)(jia)(jia)熱器輸出(chu)功率,對發(fa)熱元件(jian)的(de)(de)(de)電(dian)阻性負載(zai)實現溫(wen)度(du)(du)(du)控制(zhi)。使介質溫(wen)度(du)(du)(du)均勻,達到(dao)所(suo)需要(yao)(yao)求;當發(fa)熱元件(jian)超溫(wen)或低液位時,發(fa)熱元件(jian)的(de)(de)(de)聯鎖保護裝置(zhi)立即切斷加(jia)(jia)(jia)(jia)熱電(dian)源(yuan)避免發(fa)熱元件(jian)燒(shao)壞,延長(chang)使用(yong)壽命。
