電取暖(nuan)器故障維(wei)修
(1)不發熱:
不發熱,說明石英電暖器的電路(lu)不通。應從電源(yuan)(yuan)保險(xian)絲開(kai)始逐(zhu)步仔細檢(jian)查,檢(jian)查電源(yuan)(yuan)保險(xian)絲是(shi)否(fou)熔斷(duan),檢(jian)查電暖(nuan)器的電源(yuan)(yuan)插頭是(shi)否(fou)接(jie)觸不良(liang)。檢(jian)查電暖(nuan)器的電源(yuan)(yuan)引(yin)線(xian)是(shi)否(fou)斷(duan)路(lu),檢(jian)查石英管兩端是(shi)否(fou)松脫或石英管斷(duan)路(lu),如有(you)溫控元件(jian)、過熱保護裝置(zhi)、防止(zhi)傾倒安(an)全開(kai)關,還應檢(jian)查這些(xie)部件(jian)是(shi)否(fou)斷(duan)路(lu)。
對于(yu)接(jie)觸不(bu)良(liang),可(ke)用細(xi)砂紙仔(zi)細(xi)打磨,使之接(jie)觸良(liang)好(hao)(hao)。對于(yu)斷路,浴(yu)霸十大品牌排(pai)名,可(ke)以(yi)重新接(jie)好(hao)(hao)或(huo)更換(huan)已損壞的(de)部件。值得往意的(de)是,當電暖器放置(zhi)不(bu)平時,有可(ke)能導致防止(zhi)傾倒安(an)全(quan)開關(guan)斷開,遇(yu)到這種(zhong)情況,只要把(ba)電映器放置(zhi)水(shui)平,即可(ke)使防止(zhi)傾倒安(an)全(quan)開關(guan)恢復正(zheng)常的(de)閉(bi)合狀(zhuang)態。
(2)電熱管亮度不均勻:
電(dian)(dian)(dian)(dian)熱(re)(re)管(guan)(guan)亮度(du)不均(jun)勻(yun)(yun)(yun)的(de)(de)問題(ti),在遠紅外電(dian)(dian)(dian)(dian)暖(nuan)器(qi)中出現(xian)較(jiao)多(duo),而且(qie)是對(dui)元件使(shi)(shi)用(yong)壽(shou)命極有(you)影響的(de)(de)一個問題(ti)。從(cong)使(shi)(shi)用(yong)的(de)(de)角度(du)講,若使(shi)(shi)用(yong)不當(dang)有(you)時(shi)會造(zao)(zao)成(cheng)亮度(du)不均(jun)勻(yun)(yun)(yun),比如臥式電(dian)(dian)(dian)(dian)暖(nuan)器(qi)當(dang)立式使(shi)(shi)用(yong),造(zao)(zao)成(cheng)電(dian)(dian)(dian)(dian)熱(re)(re)絲(si)下垂,或(huo)者立式電(dian)(dian)(dian)(dian)暖(nuan)器(qi)的(de)(de)電(dian)(dian)(dian)(dian)熱(re)(re)絲(si)處(chu)理(li)不當(dang)(比如把(ba)電(dian)(dian)(dian)(dian)熱(re)(re)絲(si)從(cong)管(guan)(guan)中拉出檢修后再放(fang)敏人時(shi)造(zao)(zao)成(cheng)疏密不均(jun)勻(yun)(yun)(yun)),電(dian)(dian)(dian)(dian)壓過高造(zao)(zao)成(cheng)溫(wen)度(du)過高導(dao)致(zhi)電(dian)(dian)(dian)(dian)熱(re)(re)絲(si)下垂等。電(dian)(dian)(dian)(dian)暖(nuan)器(qi)一旦(dan)出現(xian)亮度(du)不均(jun)勻(yun)(yun)(yun),則在較(jiao)亮的(de)(de)位置會因熱(re)(re)最集中而加(jia)速權(quan)化(hua),減(jian)短壽(shou)命。
克服的辦法:
①要按產(chan)品說明書(shu)要求正(zheng)確(que)使用,不能(neng)在超過預(yu)定電(dian)壓(ya)的(de)(de)條件下(xia)(xia)(xia)使用,因為超壓(ya)意(yi)味著超溫,而任何電(dian)熱合金(jin)絲在超高溫條件下(xia)(xia)(xia),其機(ji)械(xie)(xie)強度是要下(xia)(xia)(xia)降(jiang)的(de)(de)。對于立式電(dian)暖器(qi)(qi)來講,機(ji)械(xie)(xie)強度下(xia)(xia)(xia)降(jiang)會造成電(dian)熱絲下(xia)(xia)(xia)垂從而出現上硫(liu)(liu)下(xia)(xia)(xia)密。電(dian)暖器(qi)(qi)在通電(dian)發熱的(de)(de)情況下(xia)(xia)(xia),任意(yi)搬動,或受碰(peng)擊,也是造成硫(liu)(liu)密不均(jun)勻(yun)的(de)(de)原(yuan)因。
②修理(li)后一(yi)定(ding)要(yao)正確安裝,保證產品原來性能。
對于遠紅(hong)外(wai)石(shi)(shi)(shi)英(ying)(ying)(ying)電暇器,石(shi)(shi)(shi)英(ying)(ying)(ying)管(guan)(guan)若(ruo)出(chu)現亮度不(bu)均(jun)勻,即出(chu)現電熱絲硫(liu)疏密(mi)不(bu)均(jun)勻的(de)問(wen)題(ti)(ti),要想糾(jiu)正(zheng),一(yi)般是很(hen)困難的(de)。有(you)時,若(ruo)認為必須(xu)糾(jiu)正(zheng),可以將(jiang)電熱絲從(cong)石(shi)(shi)(shi)英(ying)(ying)(ying)管(guan)(guan)中抽出(chu),將(jiang)其(qi)螺距仔細撥均(jun)勻,或重(zhong)繞一(yi)遍,然后再穿進管(guan)(guan)中,可使疏密(mi)不(bu)均(jun)勻的(de)問(wen)題(ti)(ti)得到(dao)改善。
(3)熱度忽離忽低:
熱度(du)忽(hu)(hu)高(gao)忽(hu)(hu)低的(de)(de)根本(ben)原(yuan)因(yin)是電(dian)(dian)(dian)路(lu)中存在(zai)接(jie)(jie)觸不(bu)(bu)良(liang)的(de)(de)問(wen)硒,包括插座、開關(guan)松動(dong),電(dian)(dian)(dian)熱絲引線(xian)接(jie)(jie)頭松動(dong),浴霸電(dian)(dian)(dian)熱絲本(ben)身有忽(hu)(hu)接(jie)(jie)忽(hu)(hu)斷(duan)的(de)(de)熔斷(duan)點(dian)。對于新使(shi)用(yong)的(de)(de)電(dian)(dian)(dian)暖器(qi)若(ruo)出(chu)現(xian)熱度(du)忽(hu)(hu)高(gao)忽(hu)(hu)低的(de)(de)問(wen)題,多數情況下是因(yin)生(sheng)產(chan)安裝時某一(yi)(yi)個緊固螺絲未擰(ning)緊,若(ruo)將各緊固螺絲擰(ning)緊一(yi)(yi)遍,一(yi)(yi)般(ban)即可排除故(gu)障(zhang)點(dian)。當(dang)然在(zai)供電(dian)(dian)(dian)線(xian)路(lu)中,比如(ru)電(dian)(dian)(dian)源閘刀、保險絲等(deng)部(bu)位(wei)若(ruo)存在(zai)接(jie)(jie)觸不(bu)(bu)良(liang)問(wen)題,也是造成熱度(du)忽(hu)(hu)高(gao)忽(hu)(hu)低的(de)(de)原(yuan)因(yin)。碰到這種故(gu)障(zhang)時一(yi)(yi)定要積極查找故(gu)障(zhang)點(dian),不(bu)(bu)能勉(mian)強使(shi)用(yong)。因(yin)為電(dian)(dian)(dian)路(lu)中存在(zai)接(jie)(jie)觸不(bu)(bu)良(liang)時,將危及到安全問(wen)題。
(4)外殼過熱:
遠紅(hong)外電(dian)(dian)暖器(qi)(qi)都有(you)反射(she)(she)(she)罩(zhao),浴霸(ba)它將(jiang)遠紅(hong)外光(guang)有(you)效地反射(she)(she)(she)到被(bei)加(jia)熱空間(jian)中(zhong)去(qu),若反射(she)(she)(she)罩(zhao)不清(qing)潔將(jiang)使其反射(she)(she)(she)能力下降,使滯留(liu)在電(dian)(dian)暖器(qi)(qi)中(zhong)的熱量較多,從而使電(dian)(dian)暖器(qi)(qi)本(ben)身溫(wen)度升(sheng)高(gao)。因此保(bao)證(zheng)反射(she)(she)(she)罩(zhao)的光(guang)亮清(qing)沽,是降低電(dian)(dian)暖器(qi)(qi)本(ben)身溫(wen)升(sheng)的有(you)效方法。除此之(zhi)外,與反射(she)(she)(she)罩(zhao)的設(she)計、安裝合理與否也(ye)有(you)一定關系。
對于裝有風扇進行送風對流的石英電暖器,若送風電動機不轉,也會造成電暖器外殼過熱。
