旭誠電伴熱(re)帶規格(ge)齊全-屋頂除雪恒功(gong)率(lv)電伴熱(re)帶-恒功(gong)率(lv)電伴熱(re)帶

電(dian)伴(ban)熱(re)(re)系統組成部件(jian)(jian)有哪些？ 防(fang)爆(bao)溫度控(kong)(kong)制器，通用(yong)型號是(shi)BJW，它利用(yong)熱(re)(re)電(dian)偶(ou)溫控(kong)(kong)探頭測量電(dian)伴(ban)熱(re)(re)帶溫度，并手動控(kong)(kong)溫，PTC自(zi)限溫電(dian)伴(ban)熱(re)(re)帶可以(yi)(yi)不安裝(zhuang)這一(yi)部件(jian)(jian)。鋁(lv)箔膠帶是(shi)用(yong)來擴大電(dian)伴(ban)熱(re)(re)帶受熱(re)(re)面積，增加聚熱(re)(re)絕熱(re)(re)范圍，提高伴(ban)熱(re)(re)效(xiao)率的(de)部件(jian)(jian)。電(dian)伴(ban)熱(re)(re)廠家提供熱(re)(re)敏膠帶，它起到固定(ding)電(dian)伴(ban)熱(re)(re)系統的(de)作(zuo)用(yong)，通常是(shi)將電(dian)伴(ban)熱(re)(re)帶固定(ding)在(zai)被伴(ban)熱(re)(re)的(de)管(guan)道或設備上，也可以(yi)(yi)使用(yong)不銹鋼(gang)扎帶代替。警(jing)示標簽是(shi)在(zai)施工完成后，粘貼在(zai)伴(ban)熱(re)(re)管(guan)線外(wai)表面作(zuo)為示意和通電(dian)示警(jing)作(zuo)用(yong)的(de)部件(jian)(jian)。

電伴熱帶原理 (1)自限溫電伴熱帶 自限溫電伴熱帶又稱自控溫電伴熱帶，它是(shi)新一代帶狀恒(heng)溫(wen)(wen)電(dian)(dian)熱產品(pin)，由高(gao)分子導電(dian)(dian)碳(tan)粒和兩根平行母(mu)線外加絕緣(yuan)層構成，其(qi)PTC發(fa)熱元件(jian)的(de)(de)電(dian)(dian)阻率(lv)具有很(hen)高(gao)的(de)(de)正溫(wen)(wen)度系數且相互并(bing)聯。 自(zi)限溫(wen)(wen)電(dian)(dian)伴(ban)熱帶能夠自(zi)動限制發(fa)熱溫(wen)(wen)度，并(bing)隨被伴(ban)熱體溫(wen)(wen)度自(zi)動調節輸出(chu)功(gong)率(lv);可(ke)以任(ren)意剪(jian)切或在一定長度范(fan)圍(wei)內接(jie)長使用;允許多(duo)次交叉重疊(die)而無高(gao)溫(wen)(wen)過熱燒毀之慮;維護(hu)簡便且節約(yue)電(dian)(dian)能。 (2)恒(heng)功(gong)率(lv)電(dian)(dian)伴(ban)熱帶 恒(heng)功(gong)率(lv)電(dian)(dian)伴(ban)熱帶分為并(bing)聯電(dian)(dian)伴(ban)熱帶和串聯電(dian)(dian)伴(ban)熱帶，指(zhi)電(dian)(dian)伴(ban)熱帶通電(dian)(dian)后(hou)即以一恒(heng)定的(de)(de)功(gong)率(lv)發(fa)熱，并(bing)不隨環(huan)境溫(wen)(wen)度改變而變化。
