防爆電(dian)(dian)伴(ban)(ban)熱帶-防爆電(dian)(dian)伴(ban)(ban)熱帶價格-旭誠電(dian)(dian)伴(ban)(ban)熱帶型號(hao)齊(qi)全

電(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)帶(dai)(dai)(dai)安裝(zhuang)(zhuang)(zhuang)前的準備(bei)工作有(you)哪些？ 一.電(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)運輸到安裝(zhuang)(zhuang)(zhuang)現場,要(yao)對物(wu)料進行清點數(shu)量(liang),除(chu)了電(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)帶(dai)(dai)(dai)外,電(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)帶(dai)(dai)(dai)也有(you)相應的輔(fu)材,例(li)如鋁箔膠(jiao)帶(dai)(dai)(dai),熱(re)(re)(re)(re)(re)敏膠(jiao)帶(dai)(dai)(dai),不銹(xiu)鋼(gang)扎(zha)帶(dai)(dai)(dai)(用于(yu)(yu)固定溫控器,接(jie)線盒等),防爆膠(jiao),支架,配(pei)電(dian)箱,電(dian)氣電(dian)纜等.其中關于(yu)(yu)電(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)帶(dai)(dai)(dai)檢查表(biao)面(mian)要(yao)無損傷(shang),有(you)相應的產品合格證(zheng)等 二.管道(dao)罐體等表(biao)面(mian)去(qu)除(chu)毛刺(ci),確保平滑,以免(mian)(mian)造(zao)成電(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)帶(dai)(dai)(dai)在(zai)安裝(zhuang)(zhuang)(zhuang)破壞(huai)(huai)絕緣層(ceng) 三(san).電(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)帶(dai)(dai)(dai)放置時,應平直,不打(da)結(jie)或彎曲.在(zai)運輸中避免(mian)(mian)在(zai)地上拖拽.電(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)帶(dai)(dai)(dai)避免(mian)(mian)放置在(zai)管道(dao)的尖銳邊緣,禁(jin)止和保護 四.在(zai)安裝(zhuang)(zhuang)(zhuang)電(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)帶(dai)(dai)(dai)之(zhi)前,如果有(you)焊接(jie)和吊裝(zhuang)(zhuang)(zhuang)作業,應提前完(wan)成.避免(mian)(mian)在(zai)電(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)哎(ai)安裝(zhuang)(zhuang)(zhuang)防止焊渣濺到電(dian)熱(re)(re)(re)(re)(re)帶(dai)(dai)(dai)上并損壞(huai)(huai)絕緣層(ceng).

電(dian)伴(ban)熱帶(dai)的(de)(de)構(gou)成(cheng)：是在(zai)(zai)兩根(gen)平(ping)(ping)行(xing)(xing)母線之(zhi)間(jian)均勻的(de)(de)加上(shang)聚錄乙(yi)烯或塑質材料加工(gong)形成(cheng)的(de)(de)芯帶(dai)。是在(zai)(zai)高溫(wen)融化覆蓋，在(zai)(zai)進(jin)行(xing)(xing)冷卻定型之(zhi)后形成(cheng)。當它們跨(kua)接在(zai)(zai)兩根(gen)平(ping)(ping)行(xing)(xing)母線上(shang)時，就構(gou)成(cheng)芯帶(dai)的(de)(de)回路。電(dian)伴(ban)熱帶(dai)一(yi)端的(de)(de)兩根(gen)母線接通供電(dian)電(dian)源后，電(dian)流從(cong)一(yi)根(gen)母線流過到(dao)達(da)另一(yi)根(gen)母線形成(cheng)回路。這二根(gen)母線通過其(qi)的(de)(de)電(dian)阻值(zhi)進(jin)行(xing)(xing)發熱，將電(dian)能轉化成(cheng)熱能，在(zai)(zai)通過包裹層對管(guan)道等設備進(jin)行(xing)(xing)伴(ban)熱保溫(wen)。如果芯帶(dai)溫(wen)度(du)(du)升(sheng)到(dao)相應的(de)(de)極限溫(wen)度(du)(du)時，這時的(de)(de)電(dian)阻值(zhi)無法在(zai)(zai)提(ti)供較高的(de)(de)溫(wen)度(du)(du)，芯帶(dai)的(de)(de)溫(wen)度(du)(du)即已經達(da)到(dao)高額定值(zhi)，這時就是自(zi)動控制電(dian)伴(ban)熱帶(dai)的(de)(de)溫(wen)度(du)(du)不(bu)再(zai)升(sheng)高(自(zi)控溫(wen)度(du)(du))。

電(dian)(dian)伴(ban)熱(re)帶怎么(me)安(an)裝(zhuang)？ 1、直(zhi)(zhi)線纏(chan)繞：將(jiang)一(yi)(yi)根或多根電(dian)(dian)熱(re)帶沿管(guan)道(dao)(dao)一(yi)(yi)邊直(zhi)(zhi)線放置，用(yong)鋁(lv)(lv)箔膠(jiao)帶或安(an)裝(zhuang)鋁(lv)(lv)帶將(jiang)電(dian)(dian)伴(ban)熱(re)帶固(gu)定(ding)，在管(guan)道(dao)(dao)的下(xia)半端(duan)，固(gu)定(ding)間距不大于50CM。 2、波(bo)浪纏(chan)繞：將(jiang)電(dian)(dian)熱(re)帶以波(bo)浪式與管(guan)道(dao)(dao)符合在一(yi)(yi)起，按設計每米所需負荷確定(ding)每米管(guan)道(dao)(dao)所需電(dian)(dian)把(ba)那(nei)熱(re)帶長度，然(ran)后再確定(ding)波(bo)浪曲(qu)(qu)率半徑R，鋪設時應(ying)盡量使波(bo)幅均勻(yun)，以保(bao)證(zheng)電(dian)(dian)纜系統的均勻(yun)散(san)熱(re)，用(yong)鋁(lv)(lv)箔帶沿波(bo)浪曲(qu)(qu)線黏貼伴(ban)熱(re)帶，或用(yong)鋁(lv)(lv)膠(jiao)帶粘(zhan)貼彎(wan)曲(qu)(qu)處。 3、螺旋纏(chan)繞：將(jiang)電(dian)(dian)伴(ban)熱(re)按每米管(guan)道(dao)(dao)所需長度均勻(yun)地以螺旋狀纏(chan)繞在管(guan)道(dao)(dao)上(shang)，用(yong)鋁(lv)(lv)膠(jiao)帶沿螺旋方向(xiang)固(gu)定(ding)，或用(yong)鋁(lv)(lv)膠(jiao)帶固(gu)定(ding)電(dian)(dian)伴(ban)熱(re)帶與管(guan)子上(shang)端(duan)處。
