燃氣熱水器打不著火怎么辦

燃氣熱水器打(da)(da)不著(zhu)火是燃氣(qi)熱(re)(re)水(shui)器(qi)故障(zhang)率最高的故障(zhang)現象(xiang)，現在(zai)以最普(pu)遍強排式或平(ping)衡式燃氣(qi)熱(re)(re)水(shui)器(qi)為例：具體現象(xiang)有(you)(you)排風機(ji)轉動正(zheng)常，沒有(you)(you)電(dian)火花打(da)(da)火的聲音；有(you)(you)電(dian)火花打(da)(da)火的聲音,但不能(neng)打(da)(da)著(zhu)火；有(you)(you)的是開啟燃氣(qi)熱(re)(re)水(shui)器(qi)時機(ji)內(nei)沒有(you)(you)任何反應，電(dian)源指示燈都(dou)不亮的情況(kuang)。

這些是通(tong)常熱(re)水(shui)器打不著火所表(biao)現的具體現象(xiang)。我們把燃氣熱(re)水(shui)器分四部分來具體分析維(wei)修熱(re)水(shui)器便可(ke)很(hen)容易的快速找到(dao)熱(re)水(shui)器打不著火的原因(yin)和故(gu)障點。

燃氣熱水器打不著火原因

1、燃氣(qi)(qi)通路（氣(qi)(qi)路）

無論是(shi)(shi)使用(yong)(yong)天然(ran)氣(qi)(qi)(qi)(qi)、液(ye)化石油氣(qi)(qi)(qi)(qi)、人工煤氣(qi)(qi)(qi)(qi)的(de)(de)用(yong)(yong)戶，燃(ran)(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)通(tong)(tong)(tong)路是(shi)(shi)首先要(yao)檢查的(de)(de)一(yi)步，這一(yi)部(bu)分(fen)(fen)包括進(jin)(jin)(jin)氣(qi)(qi)(qi)(qi)咀、電磁(ci)閥(fa)(fa)、水(shui)氣(qi)(qi)(qi)(qi)聯(lian)動密封閥(fa)(fa)、燃(ran)(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)分(fen)(fen)氣(qi)(qi)(qi)(qi)管(guan)、燃(ran)(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)噴咀、燃(ran)(ran)(ran)(ran)(ran)燒器(qi)或俗(su)稱火(huo)排(pai)，這些造(zao)(zao)成(cheng)燃(ran)(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)熱水(shui)器(qi)打不(bu)(bu)著(zhu)火(huo)主(zhu)(zhu)要(yao)是(shi)(shi)因(yin)(yin)為(wei)堵(du)(du)塞(sai)或不(bu)(bu)通(tong)(tong)(tong)暢(chang)，進(jin)(jin)(jin)氣(qi)(qi)(qi)(qi)咀處有(you)一(yi)過濾網(wang)，用(yong)(yong)于過濾燃(ran)(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)雜質和燃(ran)(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)異(yi)物進(jin)(jin)(jin)入燃(ran)(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)通(tong)(tong)(tong)道內部(bu)；電磁(ci)閥(fa)(fa)在不(bu)(bu)通(tong)(tong)(tong)電時的(de)(de)自然(ran)狀態(tai)下(xia)(xia)是(shi)(shi)將(jiang)燃(ran)(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)通(tong)(tong)(tong)路關閉的(de)(de)，它(ta)是(shi)(shi)靠(kao)熱水(shui)器(qi)脈沖控制器(qi)供電才將(jiang)閥(fa)(fa)門打開(kai)通(tong)(tong)(tong)氣(qi)(qi)(qi)(qi)后(hou)才能(neng)使熱水(shui)器(qi)點著(zhu)火(huo)，這個位置的(de)(de)故(gu)(gu)障(zhang)率極高(gao)，但通(tong)(tong)(tong)常不(bu)(bu)是(shi)(shi)電磁(ci)閥(fa)(fa)本身(shen)故(gu)(gu)障(zhang)造(zao)(zao)成(cheng)的(de)(de)，而(er)(er)多數是(shi)(shi)由(you)(you)于它(ta)未能(neng)得到供電電壓(ya)而(er)(er)導致(zhi)開(kai)不(bu)(bu)了閥(fa)(fa)，打不(bu)(bu)著(zhu)火(huo)的(de)(de)；水(shui)氣(qi)(qi)(qi)(qi)聯(lian)動密封閥(fa)(fa)處造(zao)(zao)成(cheng)打不(bu)(bu)著(zhu)火(huo)的(de)(de)故(gu)(gu)障(zhang)率極低(di);燃(ran)(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)分(fen)(fen)氣(qi)(qi)(qi)(qi)管(guan)也(ye)很(hen)少見出故(gu)(gu)障(zhang);燃(ran)(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)噴咀的(de)(de)孔徑(jing)很(hen)小(xiao)，個別品牌的(de)(de)特殊機型有(you)的(de)(de)比(bi)較(jiao)大(da),比(bi)如(ru)林內、能(neng)率、松下(xia)(xia)、萬(wan)和、萬(wan)家樂下(xia)(xia)鼓風等機型,主(zhu)(zhu)要(yao)由(you)(you)燃(ran)(ran)(ran)(ran)(ran)燒器(qi)的(de)(de)設計(ji)而(er)(er)定,因(yin)(yin)孔徑(jing)小(xiao),所以稍(shao)灰塵可能(neng)會造(zao)(zao)成(cheng)堵(du)(du)塞(sai)造(zao)(zao)成(cheng)火(huo)小(xiao)而(er)(er)打不(bu)(bu)著(zhu)火(huo);燃(ran)(ran)(ran)(ran)(ran)燒器(qi)也(ye)容易造(zao)(zao)成(cheng)堵(du)(du)塞(sai),堵(du)(du)塞(sai)物通(tong)(tong)(tong)常是(shi)(shi)蜘蛛網(wang)之類,這里的(de)(de)溫度和環境剛好適合做昆蟲(chong)的(de)(de)蝸居,如(ru)果熱水(shui)器(qi)間(jian)隔一(yi)段時間(jian)未使用(yong)(yong),很(hen)可能(neng)這里就(jiu)被(bei)它(ta)們占(zhan)領了,到你下(xia)(xia)次使用(yong)(yong)就(jiu)會發現火(huo)小(xiao)或打不(bu)(bu)燃(ran)(ran)(ran)(ran)(ran)火(huo)的(de)(de)原因(yin)(yin)就(jiu)在這里.

2、水路故障

燃氣熱水器水(shui)(shui)(shui)路故(gu)障主要有進水(shui)(shui)(shui)口(kou)過濾網堵(du)塞、水(shui)(shui)(shui)閥結(jie)垢、水(shui)(shui)(shui)箱銅(tong)管(guan)變(bian)形堵(du)塞、水(shui)(shui)(shui)壓(ya)低(di)等。它(ta)們造(zao)成(cheng)燃(ran)氣熱(re)水(shui)(shui)(shui)器(qi)打(da)不(bu)著火的共同點是熱(re)水(shui)(shui)(shui)器(qi)出(chu)水(shui)(shui)(shui)量會明顯減小,低(di)至(zhi)燃(ran)氣熱(re)水(shui)(shui)(shui)器(qi)的啟動(dong)壓(ya)力0.02MPa的水(shui)(shui)(shui)壓(ya)時就無法啟動(dong)熱(re)水(shui)(shui)(shui)器(qi)了，老式強制排氣式熱(re)水(shui)(shui)(shui)器(qi)這個現象(xiang)很明顯，所(suo)以(yi)排除(chu)是否因為水(shui)(shui)(shui)路故(gu)障造(zao)成(cheng)燃(ran)氣熱(re)水(shui)(shui)(shui)器(qi)打(da)不(bu)起火的原因只需(xu)要觀察出(chu)水(shui)(shui)(shui)量或水(shui)(shui)(shui)壓(ya)是否過低(di)即(ji)可，發現過低(di)按(an)前面講的步驟(zou)進行即(ji)可。

3、電路系統(tong)故障

這一部分涉及的配件較(jiao)多,是燃氣熱水(shui)器(qi)打不著火的原因查找之核(he)心部分,包(bao)括漏電(dian)保插頭、熱水(shui)器(qi)電(dian)源控制盒、脈沖(chong)點(dian)火器(qi)、電(dian)磁閥、風(feng)機啟動電(dian)容、風(feng)機、風(feng)壓檢測開關、微動開關或(huo)水(shui)流傳感器(qi)開關、點(dian)火針、感應針、冷熱水(shui)開關。

燃氣熱水器電(dian)(dian)(dian)路系統的(de)(de)(de)工(gong)(gong)(gong)(gong)作(zuo)(zuo)原(yuan)理和流程:首(shou)先微動(dong)(dong)開(kai)(kai)(kai)關被(bei)水閥頂桿推開(kai)(kai)(kai),微動(dong)(dong)開(kai)(kai)(kai)關閉合(he)使(shi)(shi)脈沖(chong)(chong)(chong)點(dian)(dian)(dian)火(huo)器(qi)工(gong)(gong)(gong)(gong)作(zuo)(zuo)（但不(bu)(bu)是(shi)在(zai)這個(ge)時候開(kai)(kai)(kai)始放電(dian)(dian)(dian)點(dian)(dian)(dian)火(huo)）,脈沖(chong)(chong)(chong)點(dian)(dian)(dian)火(huo)器(qi)發(fa)出(chu)工(gong)(gong)(gong)(gong)作(zuo)(zuo)信號傳送(song)至熱(re)(re)水器(qi)電(dian)(dian)(dian)源控(kong)制盒,進而使(shi)(shi)繼電(dian)(dian)(dian)器(qi)工(gong)(gong)(gong)(gong)作(zuo)(zuo)接通(tong)風(feng)機(ji)工(gong)(gong)(gong)(gong)作(zuo)(zuo)電(dian)(dian)(dian)壓(ya),在(zai)啟(qi)動(dong)(dong)電(dian)(dian)(dian)容(rong)的(de)(de)(de)作(zuo)(zuo)用壓(ya)風(feng)機(ji)開(kai)(kai)(kai)始轉動(dong)(dong),同(tong)時產(chan)生一(yi)個(ge)負(fu)風(feng)壓(ya)（有(you)(you)些熱(re)(re)水器(qi)設計時也(ye)有(you)(you)采用正風(feng)壓(ya)的(de)(de)(de)）,通(tong)過一(yi)條連接到(dao)風(feng)壓(ya)檢測(ce)開(kai)(kai)(kai)關的(de)(de)(de)負(fu)壓(ya)管(guan),使(shi)(shi)風(feng)壓(ya)檢測(ce)開(kai)(kai)(kai)關工(gong)(gong)(gong)(gong)作(zuo)(zuo),此返回到(dao)脈沖(chong)(chong)(chong)點(dian)(dian)(dian)火(huo)器(qi)開(kai)(kai)(kai)始連續(xu)放電(dian)(dian)(dian)和延時2秒吸開(kai)(kai)(kai)電(dian)(dian)(dian)磁閥通(tong)氣(qi)即可點(dian)(dian)(dian)著火(huo),感應針感應到(dao)火(huo)焰正常后即通(tong)過脈沖(chong)(chong)(chong)給出(chu)電(dian)(dian)(dian)磁閥持續(xu)的(de)(de)(de)維持電(dian)(dian)(dian)壓(ya),使(shi)(shi)電(dian)(dian)(dian)磁閥保持在(zai)開(kai)(kai)(kai)啟(qi)狀態,燃(ran)燒(shao)器(qi)便可持續(xu)正常工(gong)(gong)(gong)(gong)作(zuo)(zuo)。這是(shi)一(yi)條龍完(wan)美服(fu)務(wu)，任(ren)何一(yi)個(ge)環節若有(you)(you)服(fu)務(wu)不(bu)(bu)周(zhou)便會使(shi)(shi)燃(ran)氣(qi)熱(re)(re)水器(qi)點(dian)(dian)(dian)不(bu)(bu)著火(huo)。

4、機械故障

主要有(you)水(shui)氣(qi)(qi)聯動(dong)裝(zhuang)置(zhi)、風機.水(shui)氣(qi)(qi)聯動(dong)裝(zhuang)置(zhi)主要由水(shui)閥內部(bu)水(shui)壓(ya)提供(gong)動(dong)力,推動(dong)聯動(dong)桿,同時打(da)(da)開電路部(bu)分和其(qi)中一(yi)級燃氣(qi)(qi)密(mi)封通(tong)道(dao),若水(shui)氣(qi)(qi)聯動(dong)裝(zhuang)置(zhi)出現故障(zhang)整個電路部(bu)分都沒(mei)辦(ban)法工作,同樣不(bu)打(da)(da)火水(shui)不(bu)熱(re)的;風機部(bu)分若因風葉卡死或(huo)電機轉速慢達不(bu)到(dao)風壓(ya)檢(jian)測(ce)開關的啟動(dong)壓(ya)力,脈沖點火器(qi)無法得(de)風壓(ya)檢(jian)測(ce)開關的信號(hao),也會使燃氣(qi)(qi)熱(re)水(shui)器(qi)點不(bu)著火。

從以上四步我們不難看出，燃氣熱水器打不(bu)著火時按這四步(bu)檢查(cha)，其故障(zhang)原(yuan)因自然就明了(le)了(le)，以上維(wei)修(xiu)檢查(cha)步(bu)驟熱(re)水(shui)器維(wei)修(xiu)人(ren)員(yuan)可以參照進行操作，另(ling)外小編在此建(jian)議廣大(da)用戶：燃氣行業屬于危險(xian)行業，非(fei)熱(re)水(shui)器維(wei)修(xiu)人(ren)員(yuan)請勿自行維(wei)修(xiu)熱(re)水(shui)器，維(wei)修(xiu)時應(ying)報各品牌的專業售后維(wei)修(xiu)。
