電伴熱外保溫(wen)實際(ji)上是(shi)電伴熱(re)帶熱(re)產品(pin)的稱呼，通常(chang)是(shi)指能夠(gou)自動控制溫(wen)度的自限溫(wen)度電附(fu)帶熱(re)帶，根據維持溫(wen)度的高低可以分為(wei)低溫(wen)、中溫(wen)和高溫(wen)。

最近有客戶(hu)咨(zi)詢電伴熱外保溫層怎么(me)才能包(bao)裝好？

這(zhe)可能從來沒(mei)有接觸過電(dian)伴(ban)(ban)熱(re)(re)系統(tong)，但實際上電(dian)伴(ban)(ban)熱(re)(re)帶(自(zi)限溫(wen)(wen)伴(ban)(ban)熱(re)(re)帶)的(de)設置特別方便，不(bu)像串(chuan)聯恒定功率電(dian)伴(ban)(ban)熱(re)(re)帶和MI加(jia)熱(re)(re)電(dian)纜(lan)那(nei)樣(yang)斷裂，不(bu)能交叉，不(bu)是聯合熱(re)(re)帶，(自(zi)限溫(wen)(wen)伴(ban)(ban)熱(re)(re)帶)在可自(zi)由切(qie)割交叉卷(juan)的(de)同時，不(bu)使(shi)用溫(wen)(wen)度調節器，使(shi)用自(zi)限溫(wen)(wen)伴(ban)(ban)熱(re)(re)帶保溫(wen)(wen)時，只需(xu)直接鋪在設備表面或卷(juan)繞即可，安裝完畢后可通電(dian)對設備進行保溫(wen)(wen)。

對(dui)于口徑比較粗的管道或罐(guan)體來說(shuo)，電伴熱外保溫這樣安裝(zhuang)會更好些。

管(guan)(guan)道的(de)(de)(de)(de)管(guan)(guan)徑較粗，因(yin)此以1:2的(de)(de)(de)(de)比例選擇電(dian)(dian)熱(re)(re)帶(dai)，卷繞間(jian)距為(wei)10厘米左右進行卷繞安裝，直(zhi)接(jie)鋪(pu)設后(hou)只(zhi)要(yao)將(jiang)電(dian)(dian)伴(ban)熱(re)(re)帶(dai)沿著配(pei)管(guan)(guan)筆直(zhi)鋪(pu)設即可(ke)(ke)。用(yong)(yong)(yong)(yong)鋁帶(dai)或(huo)膠帶(dai)把電(dian)(dian)伴(ban)熱(re)(re)帶(dai)固(gu)定在(zai)(zai)(zai)管(guan)(guan)子上(shang)(shang)。自(zi)(zi)限溫(wen)伴(ban)熱(re)(re)帶(dai)的(de)(de)(de)(de)使用(yong)(yong)(yong)(yong)長度(du)為(wei)100米，超過使用(yong)(yong)(yong)(yong)長度(du)時，必(bi)須用(yong)(yong)(yong)(yong)防(fang)爆配(pei)電(dian)(dian)箱連(lian)接(jie)使用(yong)(yong)(yong)(yong)。電(dian)(dian)源(yuan)(yuan)(yuan)端(duan)子箱的(de)(de)(de)(de)安裝需(xu)要(yao)準備銅鼻(bi)、剪刀、老虎鉗等，電(dian)(dian)源(yuan)(yuan)(yuan)端(duan)子箱的(de)(de)(de)(de)內部有4個(ge)端(duan)子，底部有2個(ge)平坦的(de)(de)(de)(de)電(dian)(dian)熱(re)(re)帶(dai)進出口，側面有圓柱形的(de)(de)(de)(de)電(dian)(dian)纜，打開(kai)電(dian)(dian)源(yuan)(yuan)(yuan)端(duan)子箱后(hou)，可(ke)(ke)以自(zi)(zi)由連(lian)接(jie)2個(ge)電(dian)(dian)子端(duan)子。電(dian)(dian)熱(re)(re)防(fang)爆電(dian)(dian)源(yuan)(yuan)(yuan)端(duan)子箱的(de)(de)(de)(de)配(pei)線無需(xu)分為(wei)零線和活(huo)性(xing)線，因(yin)此直(zhi)接(jie)連(lian)接(jie)，完成配(pei)線的(de)(de)(de)(de)用(yong)(yong)(yong)(yong)電(dian)(dian)熱(re)(re)防(fang)爆電(dian)(dian)源(yuan)(yuan)(yuan)端(duan)子箱、緊固(gu)件(jian)和密(mi)封劑固(gu)定。使用(yong)(yong)(yong)(yong)恒定功率電(dian)(dian)熱(re)(re)帶(dai)時，需(xu)要(yao)設置溫(wen)度(du)調(diao)節(jie)器(qi)來控制溫(wen)度(du)。 此處(chu)為(wei)自(zi)(zi)限溫(wen)度(du)熱(re)(re)帶(dai)，因(yin)此無需(xu)使用(yong)(yong)(yong)(yong)溫(wen)度(du)調(diao)節(jie)器(qi)。 電(dian)(dian)熱(re)(re)帶(dai)的(de)(de)(de)(de)設置結束后(hou)，在(zai)(zai)(zai)外面包上(shang)(shang)保溫(wen)棉(mian)就(jiu)(jiu)可(ke)(ke)以了。 在(zai)(zai)(zai)需(xu)要(yao)保溫(wen)的(de)(de)(de)(de)時候打開(kai)電(dian)(dian)源(yuan)(yuan)(yuan)就(jiu)(jiu)可(ke)(ke)以了。
