管(guan)道保(bao)(bao)溫(wen)使用電伴(ban)(ban)熱系(xi)統(tong)相對于傳(chuan)統(tong)伴(ban)(ban)熱方(fang)式來說,電伴(ban)(ban)熱的工作效率(lv)更(geng)高,溫(wen)度均勻,使用期(qi)間(jian)更(geng)加安全,且周期(qi)成(cheng)本低,節能環(huan)保(bao)(bao)。隨(sui)著電伴(ban)(ban)熱保(bao)(bao)溫(wen)技術的不斷成(cheng)熟(shu),被越來越多的應用在(zai)管(guan)道設備的防凍保(bao)(bao)溫(wen)中去。
電伴(ban)(ban)熱帶(dai)作為一(yi)種伴(ban)(ban)熱保溫產品已被用(yong)戶所認同,它(ta)適(shi)用(yong)于多個領域,無論是民(min)用(yong)管道還是工業石油(you)化工管道伴(ban)(ban)熱。起初電伴(ban)(ban)熱帶(dai)是專門(men)針(zhen)對液(ye)體管道而設計的,因此(ci)液(ye)體管道一(yi)旦發生電伴(ban)(ban)熱帶(dai)理所當然成為了伴(ban)(ban)熱產品。
在(zai)開(kai)采(cai)中(zhong),對井(jing)筒(tong)使用電(dian)伴(ban)(ban)熱(re)(re)帶,從(cong)經(jing)濟(ji)上(shang)考(kao)慮,提前(qian)對使用的(de)(de)(de)長度和伴(ban)(ban)熱(re)(re)的(de)(de)(de)強度,進行優化處理,在(zai)保證(zheng)溫度的(de)(de)(de)基礎上(shang),盡(jin)量是(shi)越小越好。電(dian)伴(ban)(ban)熱(re)(re)帶主(zhu)要(yao)是(shi)工(gong)作靈活(huo),自動化處理,管理上(shang)方(fang)便,工(gong)作中(zhong)也能避免(mian)危險的(de)(de)(de)發(fa)生。這一特點,主(zhu)要(yao)是(shi)因為在(zai)內部的(de)(de)(de)高分子加熱(re)(re)聚合(he)物(wu)具有記憶(yi)功(gong)(gong)能,它能夠感(gan)應周圍(wei)的(de)(de)(de)溫度,來(lai)調節(jie)輸出的(de)(de)(de)功(gong)(gong)率,溫度高時功(gong)(gong)率小,溫度低(di)時功(gong)(gong)率大。而它的(de)(de)(de)工(gong)作狀態則能通過溫度調節(jie)器來(lai)控(kong)制和預(yu)設,使用起(qi)來(lai)方(fang)便安全。另外,電(dian)伴(ban)(ban)熱(re)(re)帶由加熱(re)(re)聚合(he)物(wu),導電(dian)芯線還有絕(jue)緣保護層等(deng)組成,使用時幾乎不會發(fa)生大故障,放心使用。
