導熱油電加熱爐的(de)發熱(re)管(guan)是(shi)由(you)管(guan)狀電(dian)(dian)(dian)熱(re)組件用(yong)于空氣(qi)加熱(re)系(xi)統的(de)吹風管(guan)道中,作吹送熱(re)空氣(qi)用(yong),也可(ke)(ke)作為各種(zhong)烘箱,油(you)漆干燥,電(dian)(dian)(dian)爐(lu)的(de)發熱(re)組件。油(you)加熱(re)電(dian)(dian)(dian)熱(re)管(guan)是(shi)將多(duo)根電(dian)(dian)(dian)熱(re)管(guan)焊(han)接或擰裝到一(yi)個(ge)法(fa)蘭(lan)(lan)上,形成一(yi)個(ge)大功(gong)率的(de),可(ke)(ke)整(zheng)體(ti)折(zhe)裝的(de)加熱(re)器。可(ke)(ke)將溫控探頭焊(han)在法(fa)蘭(lan)(lan)上,做成溫度可(ke)(ke)控的(de)整(zheng)體(ti)加熱(re)器。防止(zhi)干燒,有效延(yan)長使用(yong)壽命(ming)。有兩種(zhong)連接方式,一(yi)是(shi)螺紋連接,二是(shi)法(fa)蘭(lan)(lan)連接。也就是(shi)俗稱的(de)平板法(fa)蘭(lan)(lan)連接。
油加熱(re)電熱(re)管的(de)操作注意
導熱油電加熱爐的電熱(re)(re)(re)管用(yong)于加(jia)熱(re)(re)(re)易(yi)融化(hua)金屬(shu)或固(gu)態的(de)硝鹽、石蠟、瀝(li)青(qing)等(deng)物(wu)質(zhi)時(shi),要(yao)先(xian)對加(jia)熱(re)(re)(re)物(wu)質(zhi)進行熔(rong)化(hua),這時(shi)可以降低電熱(re)(re)(re)管的(de)外接電壓(ya),當熔(rong)化(hua)完成后(hou)再恢復為(wei)額定(ding)電壓(ya)。另外,油加(jia)熱(re)(re)(re)電熱(re)(re)(re)管加(jia)熱(re)(re)(re)硝鹽等(deng)容易(yi)發生(sheng)爆(bao)炸事故(gu)的(de)物(wu)質(zhi)時(shi),要(yao)充分考慮(lv)安(an)全措(cuo)施。
油加熱電熱管用于空氣加熱時,要注意電熱管的均勻排列,這樣做的好處是保證電熱管有比較充分和均勻的散熱空間,并盡可能的保證了空氣的流動性,提高電熱管的加熱效率。導熱油電加熱爐電熱(re)管內部的(de)(de)間隙內填充有氧化鎂(mei)砂,在油加熱(re)電熱(re)管出(chu)線(xian)端的(de)(de)氧化鎂(mei)砂容易因(yin)為雜質和(he)水分的(de)(de)滲入而(er)受(shou)到(dao)污(wu)染,因(yin)此(ci)要在操作時注意電熱(re)管出(chu)線(xian)端的(de)(de)狀態,避(bi)免(mian)因(yin)此(ci)造(zao)成的(de)(de)漏電事故。
導熱油電加熱爐的電(dian)(dian)(dian)(dian)熱(re)(re)(re)管(guan)的(de)(de)存放(fang)位(wei)置(zhi)必(bi)須(xu)保(bao)持(chi)干燥和適(shi)(shi)當的(de)(de)絕緣電(dian)(dian)(dian)(dian)阻,如果使(shi)用時發現(xian)電(dian)(dian)(dian)(dian)熱(re)(re)(re)管(guan)的(de)(de)存放(fang)環境絕緣電(dian)(dian)(dian)(dian)阻過小,可以低電(dian)(dian)(dian)(dian)壓通電(dian)(dian)(dian)(dian)予以恢(hui)復后(hou)再(zai)行(xing)使(shi)用。油加熱(re)(re)(re)電(dian)(dian)(dian)(dian)熱(re)(re)(re)管(guan)在使(shi)用前(qian)應有適(shi)(shi)當固定,接線(xian)的(de)(de)部分要放(fang)在保(bao)溫層的(de)(de)外面(mian),并(bing)避(bi)(bi)免(mian)(mian)接觸腐蝕性(xing)、爆炸性(xing)介質和水(shui)。油加熱(re)(re)(re)電(dian)(dian)(dian)(dian)熱(re)(re)(re)管(guan)在用于液體或(huo)金(jin)(jin)屬固體加熱(re)(re)(re)時,要注意必(bi)須(xu)將(jiang)電(dian)(dian)(dian)(dian)熱(re)(re)(re)管(guan)完全(quan)置(zhi)入被(bei)加熱(re)(re)(re)物(wu)體內,不允許出現(xian)電(dian)(dian)(dian)(dian)熱(re)(re)(re)管(guan)空燒的(de)(de)情況。油加熱(re)(re)(re)電(dian)(dian)(dian)(dian)熱(re)(re)(re)管(guan)使(shi)用后(hou)如果外層金(jin)(jin)屬管(guan)殼上結有水(shui)垢或(huo)碳時,要對其進行(xing)及時的(de)(de)清除,以避(bi)(bi)免(mian)(mian)對電(dian)(dian)(dian)(dian)熱(re)(re)(re)管(guan)的(de)(de)散熱(re)(re)(re)性(xing)能和使(shi)用壽命造成影響(xiang)。
