燃氣熱水器打不著火怎么辦

燃氣熱水器打(da)(da)不著火是燃(ran)氣(qi)熱(re)水(shui)器(qi)故障率最高的(de)故障現(xian)象(xiang)，現(xian)在以最普遍(bian)強(qiang)排式(shi)或平衡式(shi)燃(ran)氣(qi)熱(re)水(shui)器(qi)為例(li)：具體(ti)現(xian)象(xiang)有排風機(ji)轉動正常(chang)，沒(mei)有電火花打(da)(da)火的(de)聲(sheng)音(yin)；有電火花打(da)(da)火的(de)聲(sheng)音(yin),但不能打(da)(da)著火；有的(de)是開啟燃(ran)氣(qi)熱(re)水(shui)器(qi)時機(ji)內(nei)沒(mei)有任何反(fan)應，電源指(zhi)示燈都不亮的(de)情(qing)況(kuang)。

這些是通(tong)常熱水器(qi)打不著(zhu)火(huo)(huo)所表現的(de)(de)具(ju)體(ti)現象。我們把燃氣熱水器(qi)分四部分來(lai)具(ju)體(ti)分析維修熱水器(qi)便可很容易的(de)(de)快速找到熱水器(qi)打不著(zhu)火(huo)(huo)的(de)(de)原因和故障點。

燃氣熱水器打不著火原因

1、燃氣(qi)(qi)通路（氣(qi)(qi)路）

無論(lun)是(shi)(shi)(shi)(shi)使用(yong)天然氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)、液(ye)化石油氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)、人工(gong)煤氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)的(de)用(yong)戶，燃(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)通(tong)(tong)(tong)路是(shi)(shi)(shi)(shi)首先(xian)要(yao)檢查的(de)一步，這(zhe)(zhe)一部分(fen)包括進(jin)(jin)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)咀(ju)(ju)、電(dian)(dian)磁(ci)(ci)閥、水氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)聯動密封閥、燃(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)分(fen)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)管(guan)、燃(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)噴咀(ju)(ju)、燃(ran)(ran)(ran)(ran)燒器(qi)或俗稱(cheng)火(huo)(huo)(huo)排，這(zhe)(zhe)些造(zao)(zao)成(cheng)(cheng)(cheng)燃(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)熱(re)水器(qi)打(da)不(bu)(bu)(bu)著火(huo)(huo)(huo)主要(yao)是(shi)(shi)(shi)(shi)因為(wei)堵塞(sai)或不(bu)(bu)(bu)通(tong)(tong)(tong)暢，進(jin)(jin)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)咀(ju)(ju)處(chu)有一過濾(lv)網，用(yong)于(yu)過濾(lv)燃(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)雜質和燃(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)異物進(jin)(jin)入燃(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)通(tong)(tong)(tong)道內(nei)部；電(dian)(dian)磁(ci)(ci)閥在不(bu)(bu)(bu)通(tong)(tong)(tong)電(dian)(dian)時的(de)自然狀態下是(shi)(shi)(shi)(shi)將燃(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)通(tong)(tong)(tong)路關閉的(de)，它是(shi)(shi)(shi)(shi)靠(kao)熱(re)水器(qi)脈(mo)沖控制器(qi)供電(dian)(dian)才將閥門(men)打(da)開(kai)通(tong)(tong)(tong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)后才能(neng)(neng)(neng)使熱(re)水器(qi)點著火(huo)(huo)(huo)，這(zhe)(zhe)個(ge)位置的(de)故(gu)(gu)障率極(ji)高，但通(tong)(tong)(tong)常不(bu)(bu)(bu)是(shi)(shi)(shi)(shi)電(dian)(dian)磁(ci)(ci)閥本身故(gu)(gu)障造(zao)(zao)成(cheng)(cheng)(cheng)的(de)，而(er)多數(shu)是(shi)(shi)(shi)(shi)由(you)于(yu)它未(wei)能(neng)(neng)(neng)得到(dao)(dao)供電(dian)(dian)電(dian)(dian)壓而(er)導致開(kai)不(bu)(bu)(bu)了閥，打(da)不(bu)(bu)(bu)著火(huo)(huo)(huo)的(de)；水氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)聯動密封閥處(chu)造(zao)(zao)成(cheng)(cheng)(cheng)打(da)不(bu)(bu)(bu)著火(huo)(huo)(huo)的(de)故(gu)(gu)障率極(ji)低;燃(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)分(fen)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)管(guan)也(ye)很(hen)少見出故(gu)(gu)障;燃(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)噴咀(ju)(ju)的(de)孔徑很(hen)小(xiao)，個(ge)別品牌(pai)的(de)特殊機型(xing)有的(de)比較大,比如(ru)林內(nei)、能(neng)(neng)(neng)率、松(song)下、萬和、萬家樂下鼓風等(deng)機型(xing),主要(yao)由(you)燃(ran)(ran)(ran)(ran)燒器(qi)的(de)設計而(er)定,因孔徑小(xiao),所以(yi)稍灰塵(chen)可能(neng)(neng)(neng)會造(zao)(zao)成(cheng)(cheng)(cheng)堵塞(sai)造(zao)(zao)成(cheng)(cheng)(cheng)火(huo)(huo)(huo)小(xiao)而(er)打(da)不(bu)(bu)(bu)著火(huo)(huo)(huo);燃(ran)(ran)(ran)(ran)燒器(qi)也(ye)容易造(zao)(zao)成(cheng)(cheng)(cheng)堵塞(sai),堵塞(sai)物通(tong)(tong)(tong)常是(shi)(shi)(shi)(shi)蜘蛛網之類,這(zhe)(zhe)里(li)的(de)溫度和環境剛好適合做(zuo)昆蟲的(de)蝸居,如(ru)果熱(re)水器(qi)間隔一段時間未(wei)使用(yong),很(hen)可能(neng)(neng)(neng)這(zhe)(zhe)里(li)就被它們占(zhan)領了,到(dao)(dao)你下次使用(yong)就會發現火(huo)(huo)(huo)小(xiao)或打(da)不(bu)(bu)(bu)燃(ran)(ran)(ran)(ran)火(huo)(huo)(huo)的(de)原(yuan)因就在這(zhe)(zhe)里(li).

2、水路故障

燃氣熱水器水(shui)(shui)(shui)路(lu)(lu)故障主要有進水(shui)(shui)(shui)口過(guo)濾(lv)網(wang)堵(du)塞、水(shui)(shui)(shui)閥結(jie)垢、水(shui)(shui)(shui)箱銅管變形堵(du)塞、水(shui)(shui)(shui)壓(ya)(ya)低等(deng)。它們造成(cheng)燃(ran)氣(qi)熱水(shui)(shui)(shui)器(qi)打不著(zhu)火(huo)的(de)共(gong)同點是熱水(shui)(shui)(shui)器(qi)出水(shui)(shui)(shui)量會明顯減小,低至燃(ran)氣(qi)熱水(shui)(shui)(shui)器(qi)的(de)啟(qi)動壓(ya)(ya)力(li)0.02MPa的(de)水(shui)(shui)(shui)壓(ya)(ya)時(shi)就無法啟(qi)動熱水(shui)(shui)(shui)器(qi)了，老式強制排氣(qi)式熱水(shui)(shui)(shui)器(qi)這個(ge)現象很(hen)明顯，所以排除是否因為水(shui)(shui)(shui)路(lu)(lu)故障造成(cheng)燃(ran)氣(qi)熱水(shui)(shui)(shui)器(qi)打不起火(huo)的(de)原因只需要觀察出水(shui)(shui)(shui)量或水(shui)(shui)(shui)壓(ya)(ya)是否過(guo)低即(ji)可，發(fa)現過(guo)低按前面(mian)講(jiang)的(de)步驟(zou)進行(xing)即(ji)可。

3、電路系統故障

這一部分(fen)涉及的(de)(de)配件較多,是燃(ran)氣熱(re)(re)水器(qi)(qi)(qi)打不著火的(de)(de)原因查(cha)找之核心(xin)部分(fen),包括漏電(dian)(dian)保插頭、熱(re)(re)水器(qi)(qi)(qi)電(dian)(dian)源(yuan)控制盒、脈沖點火器(qi)(qi)(qi)、電(dian)(dian)磁(ci)閥、風(feng)機啟動電(dian)(dian)容(rong)、風(feng)機、風(feng)壓檢測開(kai)(kai)關(guan)、微動開(kai)(kai)關(guan)或水流傳感(gan)器(qi)(qi)(qi)開(kai)(kai)關(guan)、點火針(zhen)、感(gan)應針(zhen)、冷熱(re)(re)水開(kai)(kai)關(guan)。

燃氣熱水器電(dian)(dian)(dian)(dian)(dian)路(lu)系統的(de)(de)工(gong)作(zuo)(zuo)原理和流程:首(shou)先微動開(kai)(kai)關(guan)(guan)被水閥(fa)頂(ding)桿推開(kai)(kai),微動開(kai)(kai)關(guan)(guan)閉(bi)合使脈沖點(dian)(dian)(dian)火(huo)器(qi)(qi)工(gong)作(zuo)(zuo)（但不(bu)是在這個時(shi)(shi)候(hou)開(kai)(kai)始放電(dian)(dian)(dian)(dian)(dian)點(dian)(dian)(dian)火(huo)）,脈沖點(dian)(dian)(dian)火(huo)器(qi)(qi)發出工(gong)作(zuo)(zuo)信號傳送至熱水器(qi)(qi)電(dian)(dian)(dian)(dian)(dian)源控(kong)制(zhi)盒,進而使繼(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)工(gong)作(zuo)(zuo)接通風機工(gong)作(zuo)(zuo)電(dian)(dian)(dian)(dian)(dian)壓(ya),在啟(qi)動電(dian)(dian)(dian)(dian)(dian)容(rong)的(de)(de)作(zuo)(zuo)用(yong)壓(ya)風機開(kai)(kai)始轉動,同(tong)時(shi)(shi)產生一個負(fu)(fu)風壓(ya)（有(you)些(xie)熱水器(qi)(qi)設(she)計(ji)時(shi)(shi)也有(you)采用(yong)正(zheng)風壓(ya)的(de)(de)）,通過(guo)一條(tiao)(tiao)連接到風壓(ya)檢測開(kai)(kai)關(guan)(guan)的(de)(de)負(fu)(fu)壓(ya)管,使風壓(ya)檢測開(kai)(kai)關(guan)(guan)工(gong)作(zuo)(zuo),此返回(hui)到脈沖點(dian)(dian)(dian)火(huo)器(qi)(qi)開(kai)(kai)始連續放電(dian)(dian)(dian)(dian)(dian)和延(yan)時(shi)(shi)2秒吸開(kai)(kai)電(dian)(dian)(dian)(dian)(dian)磁閥(fa)通氣(qi)即(ji)可點(dian)(dian)(dian)著(zhu)火(huo),感應(ying)針感應(ying)到火(huo)焰(yan)正(zheng)常(chang)后即(ji)通過(guo)脈沖給出電(dian)(dian)(dian)(dian)(dian)磁閥(fa)持(chi)續的(de)(de)維持(chi)電(dian)(dian)(dian)(dian)(dian)壓(ya),使電(dian)(dian)(dian)(dian)(dian)磁閥(fa)保(bao)持(chi)在開(kai)(kai)啟(qi)狀態(tai),燃燒器(qi)(qi)便可持(chi)續正(zheng)常(chang)工(gong)作(zuo)(zuo)。這是一條(tiao)(tiao)龍完美(mei)服務，任何一個環節(jie)若有(you)服務不(bu)周(zhou)便會使燃氣(qi)熱水器(qi)(qi)點(dian)(dian)(dian)不(bu)著(zhu)火(huo)。

4、機械故障

主(zhu)要(yao)有(you)水氣(qi)聯動(dong)(dong)(dong)(dong)裝置(zhi)(zhi)、風機(ji).水氣(qi)聯動(dong)(dong)(dong)(dong)裝置(zhi)(zhi)主(zhu)要(yao)由水閥內部水壓提(ti)供動(dong)(dong)(dong)(dong)力,推動(dong)(dong)(dong)(dong)聯動(dong)(dong)(dong)(dong)桿,同時打開電路部分(fen)和其中一級燃(ran)氣(qi)密封通道,若水氣(qi)聯動(dong)(dong)(dong)(dong)裝置(zhi)(zhi)出現(xian)故障整(zheng)個電路部分(fen)都(dou)沒辦法工作,同樣不打火(huo)水不熱(re)的;風機(ji)部分(fen)若因風葉卡死或(huo)電機(ji)轉速慢(man)達(da)不到風壓檢(jian)測(ce)開關的啟動(dong)(dong)(dong)(dong)壓力,脈沖(chong)點(dian)火(huo)器無法得風壓檢(jian)測(ce)開關的信號(hao),也會使燃(ran)氣(qi)熱(re)水器點(dian)不著火(huo)。

從以上四步我們不難看出，燃氣熱水器打不著火(huo)時(shi)按這(zhe)四步檢查(cha)，其故障原因自然就(jiu)明了了，以上維修檢查(cha)步驟熱(re)水(shui)器維修人員可以參照(zhao)進行操(cao)作，另(ling)外小(xiao)編在此建議廣大用(yong)戶：燃氣(qi)行業(ye)屬(shu)于(yu)危險行業(ye)，非(fei)熱(re)水(shui)器維修人員請勿自行維修熱(re)水(shui)器，維修時(shi)應報各品牌的專業(ye)售后維修。
