天津自控溫電伴熱帶的用途和特點

電(dian)能對現代社會(hui)非(fei)常(chang)重要。電(dian)伴熱帶與恒功(gong)率電(dian)熱帶的(de)區別。在冬季鍋爐管道保溫防凍方(fang)面，現代社會(hui)考慮是(shi)否有蒸汽(qi)吹掃(sao)電(dian)能是(shi)非(fei)常(chang)重要的(de)。
電(dian)(dian)能對于現代社會(hui)非(fei)常(chang)重要，比如電(dian)(dian)腦、手機、電(dian)(dian)燈、網絡、空調，都離(li)不(bu)開電(dian)(dian)源(yuan)(yuan)。所以提(ti)供電(dian)(dian)源(yuan)(yuan)的(de)電(dian)(dian)廠(chang)很(hen)重要，電(dian)(dian)廠(chang)內的(de)消(xiao)防管道也是很(hen)重要的(de)一部分。電(dian)(dian)廠(chang)消(xiao)防管道中的(de)介質主要起到滅(mie)火(huo)和滅(mie)火(huo)的(de)作用(yong)，但冬季溫(wen)度低導致液體管道凍結(jie)堵塞，影響其使用(yong)。此時，我們需要使用(yong)電(dian)(dian)伴熱系(xi)統來確保(bao)管道中所需的(de)溫(wen)度，以便(bian)
電伴熱帶與恒功率(lv)電熱帶的區別(bie)。
電(dian)(dian)(dian)(dian)(dian)伴熱(re)(re)帶是將電(dian)(dian)(dian)(dian)(dian)能轉化為熱(re)(re)能用(yong)于(yu)設備防凍保(bao)溫的產品(pin)。分為自限(xian)電(dian)(dian)(dian)(dian)(dian)伴熱(re)(re)帶和恒(heng)功(gong)率(lv)電(dian)(dian)(dian)(dian)(dian)伴熱(re)(re)帶兩種。由(you)于(yu)使(shi)用(yong)場合(he)不同，選用(yong)的電(dian)(dian)(dian)(dian)(dian)伴熱(re)(re)帶也(ye)不同。但在不同的地方，選擇時要注意以下幾點區別:工作原(yuan)理自限(xian)電(dian)(dian)(dian)(dian)(dian)伴熱(re)(re)帶:接通(tong)電(dian)(dian)(dian)(dian)(dian)源后，電(dian)(dian)(dian)(dian)(dian)流由(you)其中一根(gen)導線通(tong)電(dian)(dian)(dian)(dian)(dian)，通(tong)過(guo)PTC芯(xin)帶至(zhi)另(ling)一根(gen)導線，形成一個有電(dian)(dian)(dian)(dian)(dian)阻值(zhi)的回路(lu)。恒(heng)功(gong)率(lv)電(dian)(dian)(dian)(dian)(dian)熱(re)(re)帶:絕緣(yuan)線通(tong)電(dian)(dian)(dian)(dian)(dian)時，電(dian)(dian)(dian)(dian)(dian)流通(tong)過(guo)電(dian)(dian)(dian)(dian)(dian)熱(re)(re)絲，電(dian)(dian)(dian)(dian)(dian)熱(re)(re)絲升溫傳熱(re)(re)。
冬季鍋爐管道保溫(wen)防凍需要考慮是否有蒸汽吹掃。
鍋爐(lu)是(shi)一種能量轉換器，利用(yong)燃料或其他熱(re)(re)(re)(re)能釋放的(de)(de)(de)(de)熱(re)(re)(re)(re)能將水或其他流體加(jia)熱(re)(re)(re)(re)到一定的(de)(de)(de)(de)參數(shu)。冬季(ji)外部環境溫(wen)度(du)(du)較低(di)，鍋爐(lu)管(guan)內介質容(rong)易凝結，影響生產。需要安裝伴熱(re)(re)(re)(re)保溫(wen)設施(shi)來維持溫(wen)度(du)(du)，此時(shi)電(dian)伴熱(re)(re)(re)(re)帶(dai)起到保溫(wen)作(zuo)(zuo)用(yong)。在(zai)冬季(ji)鍋爐(lu)管(guan)道保溫(wen)防凍方面(mian)，需要考慮是(shi)否(fou)有蒸(zheng)汽吹掃。蒸(zheng)汽吹掃的(de)(de)(de)(de)鍋爐(lu)管(guan)道溫(wen)度(du)(du)一般應(ying)高于100℃，甚至200度(du)(du)以(yi)上，普通(tong)電(dian)伴熱(re)(re)(re)(re)帶(dai)不(bu)能滿足其要求。例如自限電(dian)伴熱(re)(re)(re)(re)帶(dai)的(de)(de)(de)(de)工(gong)作(zuo)(zuo)溫(wen)度(du)(du)為105℃，恒功率電(dian)伴熱(re)(re)(re)(re)帶(dai)的(de)(de)(de)(de)工(gong)作(zuo)(zuo)溫(wen)度(du)(du)為150℃。同時(shi)，蒸(zheng)汽吹掃溫(wen)度(du)(du)高也(ye)可能導致電(dian)伴熱(re)(re)(re)(re)帶(dai)燒(shao)壞。那么應(ying)該(gai)選擇什(shen)么類型的(de)(de)(de)(de)電(dian)伴熱(re)(re)(re)(re)帶(dai)呢？
