燃氣熱水器打不著火怎么辦

燃氣熱水器打不著(zhu)火(huo)(huo)是(shi)燃氣(qi)熱(re)水器(qi)故(gu)障率(lv)最高(gao)的(de)(de)故(gu)障現象(xiang)，現在以最普(pu)遍強排(pai)式或平衡式燃氣(qi)熱(re)水器(qi)為例：具體(ti)現象(xiang)有(you)排(pai)風機轉動(dong)正(zheng)常，沒有(you)電(dian)火(huo)(huo)花(hua)打火(huo)(huo)的(de)(de)聲音；有(you)電(dian)火(huo)(huo)花(hua)打火(huo)(huo)的(de)(de)聲音,但不能打著(zhu)火(huo)(huo)；有(you)的(de)(de)是(shi)開啟燃氣(qi)熱(re)水器(qi)時機內沒有(you)任(ren)何反(fan)應(ying)，電(dian)源指示(shi)燈都不亮(liang)的(de)(de)情況。

這些是通(tong)常熱(re)水(shui)器(qi)打不(bu)著(zhu)火所(suo)表現(xian)的(de)(de)具體現(xian)象。我們把燃氣熱(re)水(shui)器(qi)分四(si)部分來具體分析維修熱(re)水(shui)器(qi)便可(ke)很容易的(de)(de)快速找到熱(re)水(shui)器(qi)打不(bu)著(zhu)火的(de)(de)原因和故(gu)障點。

燃氣熱水器打不著火原因

1、燃(ran)氣(qi)通路（氣(qi)路）

無論是(shi)(shi)使(shi)用(yong)(yong)天然氣(qi)(qi)、液(ye)化石油(you)氣(qi)(qi)、人工煤氣(qi)(qi)的(de)用(yong)(yong)戶，燃(ran)(ran)(ran)(ran)氣(qi)(qi)通(tong)(tong)路(lu)是(shi)(shi)首先要檢查的(de)一(yi)(yi)步，這(zhe)(zhe)一(yi)(yi)部分包括進(jin)氣(qi)(qi)咀(ju)(ju)、電磁(ci)閥(fa)(fa)、水(shui)氣(qi)(qi)聯(lian)動密封閥(fa)(fa)、燃(ran)(ran)(ran)(ran)氣(qi)(qi)分氣(qi)(qi)管、燃(ran)(ran)(ran)(ran)氣(qi)(qi)噴咀(ju)(ju)、燃(ran)(ran)(ran)(ran)燒器(qi)(qi)或(huo)俗稱火(huo)排，這(zhe)(zhe)些造(zao)(zao)成(cheng)燃(ran)(ran)(ran)(ran)氣(qi)(qi)熱(re)(re)水(shui)器(qi)(qi)打(da)(da)不(bu)著(zhu)火(huo)主(zhu)要是(shi)(shi)因(yin)為堵(du)塞(sai)或(huo)不(bu)通(tong)(tong)暢，進(jin)氣(qi)(qi)咀(ju)(ju)處有一(yi)(yi)過濾網(wang)，用(yong)(yong)于過濾燃(ran)(ran)(ran)(ran)氣(qi)(qi)雜質和燃(ran)(ran)(ran)(ran)氣(qi)(qi)異物進(jin)入(ru)燃(ran)(ran)(ran)(ran)氣(qi)(qi)通(tong)(tong)道(dao)內(nei)部；電磁(ci)閥(fa)(fa)在不(bu)通(tong)(tong)電時(shi)的(de)自然狀態下(xia)(xia)是(shi)(shi)將燃(ran)(ran)(ran)(ran)氣(qi)(qi)通(tong)(tong)路(lu)關閉的(de)，它是(shi)(shi)靠(kao)熱(re)(re)水(shui)器(qi)(qi)脈沖控制器(qi)(qi)供電才將閥(fa)(fa)門打(da)(da)開(kai)通(tong)(tong)氣(qi)(qi)后才能(neng)(neng)使(shi)熱(re)(re)水(shui)器(qi)(qi)點著(zhu)火(huo)，這(zhe)(zhe)個(ge)位(wei)置的(de)故(gu)障率極高，但通(tong)(tong)常不(bu)是(shi)(shi)電磁(ci)閥(fa)(fa)本(ben)身故(gu)障造(zao)(zao)成(cheng)的(de)，而(er)(er)(er)多數是(shi)(shi)由(you)于它未能(neng)(neng)得到供電電壓而(er)(er)(er)導(dao)致開(kai)不(bu)了閥(fa)(fa)，打(da)(da)不(bu)著(zhu)火(huo)的(de)；水(shui)氣(qi)(qi)聯(lian)動密封閥(fa)(fa)處造(zao)(zao)成(cheng)打(da)(da)不(bu)著(zhu)火(huo)的(de)故(gu)障率極低;燃(ran)(ran)(ran)(ran)氣(qi)(qi)分氣(qi)(qi)管也(ye)很(hen)少(shao)見出故(gu)障;燃(ran)(ran)(ran)(ran)氣(qi)(qi)噴咀(ju)(ju)的(de)孔徑(jing)很(hen)小(xiao)(xiao)，個(ge)別品牌的(de)特殊機型有的(de)比較大,比如林內(nei)、能(neng)(neng)率、松(song)下(xia)(xia)、萬和、萬家樂下(xia)(xia)鼓風等機型,主(zhu)要由(you)燃(ran)(ran)(ran)(ran)燒器(qi)(qi)的(de)設計而(er)(er)(er)定,因(yin)孔徑(jing)小(xiao)(xiao),所(suo)以稍灰塵可能(neng)(neng)會(hui)造(zao)(zao)成(cheng)堵(du)塞(sai)造(zao)(zao)成(cheng)火(huo)小(xiao)(xiao)而(er)(er)(er)打(da)(da)不(bu)著(zhu)火(huo);燃(ran)(ran)(ran)(ran)燒器(qi)(qi)也(ye)容易(yi)造(zao)(zao)成(cheng)堵(du)塞(sai),堵(du)塞(sai)物通(tong)(tong)常是(shi)(shi)蜘蛛網(wang)之類,這(zhe)(zhe)里(li)的(de)溫度(du)和環(huan)境剛(gang)好適(shi)合做昆(kun)蟲的(de)蝸居(ju),如果熱(re)(re)水(shui)器(qi)(qi)間隔一(yi)(yi)段時(shi)間未使(shi)用(yong)(yong),很(hen)可能(neng)(neng)這(zhe)(zhe)里(li)就(jiu)被它們(men)占領了,到你下(xia)(xia)次使(shi)用(yong)(yong)就(jiu)會(hui)發現(xian)火(huo)小(xiao)(xiao)或(huo)打(da)(da)不(bu)燃(ran)(ran)(ran)(ran)火(huo)的(de)原因(yin)就(jiu)在這(zhe)(zhe)里(li).

2、水路故障

燃氣熱水器水(shui)(shui)(shui)(shui)路故障(zhang)主要有進水(shui)(shui)(shui)(shui)口過濾網堵塞、水(shui)(shui)(shui)(shui)閥結垢、水(shui)(shui)(shui)(shui)箱(xiang)銅管變形堵塞、水(shui)(shui)(shui)(shui)壓低(di)等。它們造成(cheng)燃(ran)氣熱(re)水(shui)(shui)(shui)(shui)器(qi)(qi)打不(bu)著火的(de)共同點是熱(re)水(shui)(shui)(shui)(shui)器(qi)(qi)出(chu)水(shui)(shui)(shui)(shui)量會明(ming)顯(xian)減(jian)小(xiao),低(di)至(zhi)燃(ran)氣熱(re)水(shui)(shui)(shui)(shui)器(qi)(qi)的(de)啟動(dong)壓力(li)0.02MPa的(de)水(shui)(shui)(shui)(shui)壓時(shi)就無法(fa)啟動(dong)熱(re)水(shui)(shui)(shui)(shui)器(qi)(qi)了(le)，老式強制排氣式熱(re)水(shui)(shui)(shui)(shui)器(qi)(qi)這個現(xian)象很明(ming)顯(xian)，所以排除(chu)是否(fou)因為水(shui)(shui)(shui)(shui)路故障(zhang)造成(cheng)燃(ran)氣熱(re)水(shui)(shui)(shui)(shui)器(qi)(qi)打不(bu)起火的(de)原因只需要觀(guan)察出(chu)水(shui)(shui)(shui)(shui)量或水(shui)(shui)(shui)(shui)壓是否(fou)過低(di)即(ji)可(ke)，發現(xian)過低(di)按前面講的(de)步驟(zou)進行即(ji)可(ke)。

3、電路系統故(gu)障(zhang)

這一部(bu)分涉及的配件(jian)較(jiao)多(duo),是(shi)燃(ran)氣熱水器打(da)不著火的原因查找之核心部(bu)分,包括(kuo)漏(lou)電(dian)(dian)(dian)保插頭、熱水器電(dian)(dian)(dian)源控制(zhi)盒、脈沖點火器、電(dian)(dian)(dian)磁閥、風機啟動(dong)電(dian)(dian)(dian)容、風機、風壓檢測(ce)開(kai)關(guan)(guan)、微(wei)動(dong)開(kai)關(guan)(guan)或水流傳感器開(kai)關(guan)(guan)、點火針(zhen)、感應針(zhen)、冷熱水開(kai)關(guan)(guan)。

燃氣熱水器電(dian)(dian)(dian)路系統的工(gong)(gong)作(zuo)(zuo)(zuo)原理和流(liu)程:首先(xian)微動(dong)(dong)開(kai)關被水(shui)閥(fa)(fa)頂桿推開(kai),微動(dong)(dong)開(kai)關閉合使(shi)(shi)脈沖(chong)(chong)點(dian)火(huo)器(qi)(qi)工(gong)(gong)作(zuo)(zuo)(zuo)（但不是(shi)在(zai)這(zhe)個時候開(kai)始放電(dian)(dian)(dian)點(dian)火(huo)）,脈沖(chong)(chong)點(dian)火(huo)器(qi)(qi)發出工(gong)(gong)作(zuo)(zuo)(zuo)信號傳送至(zhi)熱(re)水(shui)器(qi)(qi)電(dian)(dian)(dian)源控制(zhi)盒,進而(er)使(shi)(shi)繼電(dian)(dian)(dian)器(qi)(qi)工(gong)(gong)作(zuo)(zuo)(zuo)接(jie)通風(feng)機工(gong)(gong)作(zuo)(zuo)(zuo)電(dian)(dian)(dian)壓(ya)(ya),在(zai)啟動(dong)(dong)電(dian)(dian)(dian)容的作(zuo)(zuo)(zuo)用(yong)(yong)壓(ya)(ya)風(feng)機開(kai)始轉動(dong)(dong),同時產生一(yi)個負風(feng)壓(ya)(ya)（有些熱(re)水(shui)器(qi)(qi)設計時也(ye)有采用(yong)(yong)正(zheng)風(feng)壓(ya)(ya)的）,通過(guo)一(yi)條連接(jie)到風(feng)壓(ya)(ya)檢(jian)(jian)測開(kai)關的負壓(ya)(ya)管,使(shi)(shi)風(feng)壓(ya)(ya)檢(jian)(jian)測開(kai)關工(gong)(gong)作(zuo)(zuo)(zuo),此返回到脈沖(chong)(chong)點(dian)火(huo)器(qi)(qi)開(kai)始連續(xu)放電(dian)(dian)(dian)和延時2秒吸開(kai)電(dian)(dian)(dian)磁閥(fa)(fa)通氣(qi)即(ji)(ji)可點(dian)著火(huo),感應(ying)針感應(ying)到火(huo)焰正(zheng)常后即(ji)(ji)通過(guo)脈沖(chong)(chong)給出電(dian)(dian)(dian)磁閥(fa)(fa)持(chi)續(xu)的維持(chi)電(dian)(dian)(dian)壓(ya)(ya),使(shi)(shi)電(dian)(dian)(dian)磁閥(fa)(fa)保持(chi)在(zai)開(kai)啟狀態,燃燒器(qi)(qi)便可持(chi)續(xu)正(zheng)常工(gong)(gong)作(zuo)(zuo)(zuo)。這(zhe)是(shi)一(yi)條龍完美服(fu)務，任(ren)何一(yi)個環節若有服(fu)務不周便會使(shi)(shi)燃氣(qi)熱(re)水(shui)器(qi)(qi)點(dian)不著火(huo)。

4、機械故障

主要有(you)水(shui)氣聯(lian)動(dong)裝置、風(feng)機(ji).水(shui)氣聯(lian)動(dong)裝置主要由(you)水(shui)閥內部(bu)(bu)水(shui)壓(ya)提供動(dong)力,推(tui)動(dong)聯(lian)動(dong)桿,同時打(da)開電(dian)路部(bu)(bu)分(fen)和其中(zhong)一(yi)級燃氣密封通(tong)道,若水(shui)氣聯(lian)動(dong)裝置出現故障整個電(dian)路部(bu)(bu)分(fen)都(dou)沒(mei)辦法工作(zuo),同樣不(bu)打(da)火水(shui)不(bu)熱(re)的;風(feng)機(ji)部(bu)(bu)分(fen)若因風(feng)葉(xie)卡(ka)死或電(dian)機(ji)轉速慢達不(bu)到風(feng)壓(ya)檢測(ce)開關的啟動(dong)壓(ya)力,脈沖點(dian)火器無法得風(feng)壓(ya)檢測(ce)開關的信號,也會使燃氣熱(re)水(shui)器點(dian)不(bu)著火。

從以上四步我們不難看出，燃氣熱水器打不著火時按這(zhe)四步檢查(cha)，其故(gu)障(zhang)原因自然就(jiu)明了了，以(yi)上(shang)維(wei)(wei)(wei)修(xiu)(xiu)(xiu)檢查(cha)步驟熱水器(qi)維(wei)(wei)(wei)修(xiu)(xiu)(xiu)人(ren)員可以(yi)參照(zhao)進(jin)行(xing)操作，另外小(xiao)編在此建議廣大用戶(hu)：燃氣行(xing)業屬于(yu)危險行(xing)業，非熱水器(qi)維(wei)(wei)(wei)修(xiu)(xiu)(xiu)人(ren)員請勿自行(xing)維(wei)(wei)(wei)修(xiu)(xiu)(xiu)熱水器(qi)，維(wei)(wei)(wei)修(xiu)(xiu)(xiu)時應報(bao)各品牌的專業售后(hou)維(wei)(wei)(wei)修(xiu)(xiu)(xiu)。
