燃氣熱水器打不著火怎么辦

燃氣熱水器打不(bu)(bu)著(zhu)火是(shi)(shi)燃(ran)氣熱水器(qi)故(gu)障率最高的故(gu)障現(xian)象，現(xian)在以最普(pu)遍強(qiang)排(pai)式或平衡(heng)式燃(ran)氣熱水器(qi)為例：具體現(xian)象有(you)排(pai)風(feng)機(ji)轉動正常，沒有(you)電(dian)火花(hua)(hua)打火的聲音；有(you)電(dian)火花(hua)(hua)打火的聲音,但(dan)不(bu)(bu)能打著(zhu)火；有(you)的是(shi)(shi)開啟燃(ran)氣熱水器(qi)時(shi)機(ji)內沒有(you)任(ren)何反應，電(dian)源指示(shi)燈都(dou)不(bu)(bu)亮的情況。

這些是通(tong)常(chang)熱(re)水(shui)器打(da)不(bu)著(zhu)(zhu)火所表現(xian)的具體現(xian)象(xiang)。我(wo)們(men)把(ba)燃(ran)氣熱(re)水(shui)器分(fen)(fen)四部分(fen)(fen)來具體分(fen)(fen)析維修熱(re)水(shui)器便可很容易的快速找到熱(re)水(shui)器打(da)不(bu)著(zhu)(zhu)火的原(yuan)因和故障點。

燃氣熱水器打不著火原因

1、燃氣通路(lu)（氣路(lu)）

無(wu)論是(shi)(shi)(shi)(shi)使(shi)用(yong)天然氣(qi)(qi)(qi)(qi)(qi)(qi)、液化石油氣(qi)(qi)(qi)(qi)(qi)(qi)、人工煤(mei)氣(qi)(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)用(yong)戶，燃(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)(qi)(qi)通路是(shi)(shi)(shi)(shi)首(shou)先要(yao)檢查的(de)(de)(de)一步，這(zhe)一部(bu)分(fen)包(bao)括進(jin)氣(qi)(qi)(qi)(qi)(qi)(qi)咀、電磁(ci)(ci)閥(fa)、水氣(qi)(qi)(qi)(qi)(qi)(qi)聯動(dong)密封閥(fa)、燃(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)(qi)(qi)分(fen)氣(qi)(qi)(qi)(qi)(qi)(qi)管、燃(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)(qi)(qi)噴咀、燃(ran)(ran)(ran)(ran)燒器(qi)(qi)(qi)或俗稱火(huo)(huo)排，這(zhe)些(xie)造(zao)(zao)(zao)(zao)成(cheng)(cheng)燃(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)(qi)(qi)熱(re)水器(qi)(qi)(qi)打不(bu)著(zhu)(zhu)火(huo)(huo)主(zhu)要(yao)是(shi)(shi)(shi)(shi)因(yin)為堵塞(sai)或不(bu)通暢，進(jin)氣(qi)(qi)(qi)(qi)(qi)(qi)咀處有一過濾網，用(yong)于(yu)過濾燃(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)(qi)(qi)雜質和(he)燃(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)(qi)(qi)異(yi)物進(jin)入(ru)燃(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)(qi)(qi)通道內(nei)部(bu)；電磁(ci)(ci)閥(fa)在不(bu)通電時的(de)(de)(de)自然狀(zhuang)態下(xia)(xia)(xia)(xia)是(shi)(shi)(shi)(shi)將燃(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)(qi)(qi)通路關閉的(de)(de)(de)，它是(shi)(shi)(shi)(shi)靠熱(re)水器(qi)(qi)(qi)脈沖控制器(qi)(qi)(qi)供電才(cai)將閥(fa)門打開通氣(qi)(qi)(qi)(qi)(qi)(qi)后才(cai)能(neng)使(shi)熱(re)水器(qi)(qi)(qi)點著(zhu)(zhu)火(huo)(huo)，這(zhe)個位置(zhi)的(de)(de)(de)故障(zhang)率(lv)極(ji)高(gao)，但通常不(bu)是(shi)(shi)(shi)(shi)電磁(ci)(ci)閥(fa)本(ben)身故障(zhang)造(zao)(zao)(zao)(zao)成(cheng)(cheng)的(de)(de)(de)，而(er)多數是(shi)(shi)(shi)(shi)由于(yu)它未能(neng)得到供電電壓而(er)導致開不(bu)了(le)閥(fa)，打不(bu)著(zhu)(zhu)火(huo)(huo)的(de)(de)(de)；水氣(qi)(qi)(qi)(qi)(qi)(qi)聯動(dong)密封閥(fa)處造(zao)(zao)(zao)(zao)成(cheng)(cheng)打不(bu)著(zhu)(zhu)火(huo)(huo)的(de)(de)(de)故障(zhang)率(lv)極(ji)低;燃(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)(qi)(qi)分(fen)氣(qi)(qi)(qi)(qi)(qi)(qi)管也很少見出故障(zhang);燃(ran)(ran)(ran)(ran)氣(qi)(qi)(qi)(qi)(qi)(qi)噴咀的(de)(de)(de)孔(kong)徑很小，個別品牌的(de)(de)(de)特殊(shu)機型(xing)有的(de)(de)(de)比(bi)較大,比(bi)如(ru)林內(nei)、能(neng)率(lv)、松(song)下(xia)(xia)(xia)(xia)、萬和(he)、萬家樂下(xia)(xia)(xia)(xia)鼓(gu)風(feng)等機型(xing),主(zhu)要(yao)由燃(ran)(ran)(ran)(ran)燒器(qi)(qi)(qi)的(de)(de)(de)設(she)計而(er)定,因(yin)孔(kong)徑小,所以稍灰塵可(ke)(ke)能(neng)會造(zao)(zao)(zao)(zao)成(cheng)(cheng)堵塞(sai)造(zao)(zao)(zao)(zao)成(cheng)(cheng)火(huo)(huo)小而(er)打不(bu)著(zhu)(zhu)火(huo)(huo);燃(ran)(ran)(ran)(ran)燒器(qi)(qi)(qi)也容易造(zao)(zao)(zao)(zao)成(cheng)(cheng)堵塞(sai),堵塞(sai)物通常是(shi)(shi)(shi)(shi)蜘蛛網之類(lei),這(zhe)里的(de)(de)(de)溫度和(he)環境剛好(hao)適合做昆蟲的(de)(de)(de)蝸居,如(ru)果熱(re)水器(qi)(qi)(qi)間隔(ge)一段時間未使(shi)用(yong),很可(ke)(ke)能(neng)這(zhe)里就(jiu)(jiu)被它們占領了(le),到你下(xia)(xia)(xia)(xia)次使(shi)用(yong)就(jiu)(jiu)會發現火(huo)(huo)小或打不(bu)燃(ran)(ran)(ran)(ran)火(huo)(huo)的(de)(de)(de)原因(yin)就(jiu)(jiu)在這(zhe)里.

2、水路故障

燃氣熱水器水(shui)(shui)(shui)(shui)路(lu)故障主(zhu)要(yao)有(you)進水(shui)(shui)(shui)(shui)口過(guo)濾網堵塞、水(shui)(shui)(shui)(shui)閥結垢、水(shui)(shui)(shui)(shui)箱(xiang)銅管(guan)變形堵塞、水(shui)(shui)(shui)(shui)壓(ya)低等。它們造(zao)成(cheng)燃氣(qi)熱(re)水(shui)(shui)(shui)(shui)器打不著火(huo)的(de)共同點是熱(re)水(shui)(shui)(shui)(shui)器出(chu)(chu)水(shui)(shui)(shui)(shui)量會明顯減(jian)小,低至(zhi)燃氣(qi)熱(re)水(shui)(shui)(shui)(shui)器的(de)啟動壓(ya)力0.02MPa的(de)水(shui)(shui)(shui)(shui)壓(ya)時就無法啟動熱(re)水(shui)(shui)(shui)(shui)器了，老式(shi)強制(zhi)排氣(qi)式(shi)熱(re)水(shui)(shui)(shui)(shui)器這(zhe)個現象(xiang)很明顯，所以排除是否因(yin)為(wei)水(shui)(shui)(shui)(shui)路(lu)故障造(zao)成(cheng)燃氣(qi)熱(re)水(shui)(shui)(shui)(shui)器打不起火(huo)的(de)原因(yin)只需要(yao)觀察出(chu)(chu)水(shui)(shui)(shui)(shui)量或水(shui)(shui)(shui)(shui)壓(ya)是否過(guo)低即(ji)可(ke)，發現過(guo)低按前面講的(de)步驟進行(xing)即(ji)可(ke)。

3、電路系統故障(zhang)

這一部(bu)分涉(she)及的配(pei)件較多,是燃氣熱水(shui)器打(da)不著火的原因查找之核心部(bu)分,包括漏(lou)電(dian)保插頭、熱水(shui)器電(dian)源控制盒、脈沖點火器、電(dian)磁(ci)閥、風機啟動(dong)電(dian)容、風機、風壓檢測開(kai)關、微動(dong)開(kai)關或水(shui)流(liu)傳感(gan)器開(kai)關、點火針、感(gan)應針、冷熱水(shui)開(kai)關。

燃氣熱水器電(dian)(dian)路系(xi)統的工作(zuo)原理和流程:首先微(wei)動開(kai)關被水(shui)(shui)(shui)閥(fa)頂(ding)桿推(tui)開(kai),微(wei)動開(kai)關閉合使(shi)脈沖(chong)(chong)點火(huo)器(qi)(qi)(qi)工作(zuo)（但(dan)不(bu)(bu)是(shi)在(zai)這個時候開(kai)始(shi)放(fang)(fang)電(dian)(dian)點火(huo)）,脈沖(chong)(chong)點火(huo)器(qi)(qi)(qi)發出工作(zuo)信號傳送至熱(re)(re)水(shui)(shui)(shui)器(qi)(qi)(qi)電(dian)(dian)源(yuan)控制盒,進而使(shi)繼電(dian)(dian)器(qi)(qi)(qi)工作(zuo)接通(tong)(tong)風(feng)機(ji)工作(zuo)電(dian)(dian)壓,在(zai)啟(qi)動電(dian)(dian)容(rong)的作(zuo)用(yong)壓風(feng)機(ji)開(kai)始(shi)轉(zhuan)動,同時產生一(yi)個負風(feng)壓（有些熱(re)(re)水(shui)(shui)(shui)器(qi)(qi)(qi)設計時也有采用(yong)正(zheng)風(feng)壓的）,通(tong)(tong)過一(yi)條(tiao)(tiao)連(lian)接到(dao)風(feng)壓檢測開(kai)關的負壓管,使(shi)風(feng)壓檢測開(kai)關工作(zuo),此返回到(dao)脈沖(chong)(chong)點火(huo)器(qi)(qi)(qi)開(kai)始(shi)連(lian)續(xu)放(fang)(fang)電(dian)(dian)和延(yan)時2秒吸開(kai)電(dian)(dian)磁閥(fa)通(tong)(tong)氣即可點著火(huo),感應針感應到(dao)火(huo)焰正(zheng)常(chang)后即通(tong)(tong)過脈沖(chong)(chong)給出電(dian)(dian)磁閥(fa)持續(xu)的維持電(dian)(dian)壓,使(shi)電(dian)(dian)磁閥(fa)保持在(zai)開(kai)啟(qi)狀態(tai),燃燒器(qi)(qi)(qi)便可持續(xu)正(zheng)常(chang)工作(zuo)。這是(shi)一(yi)條(tiao)(tiao)龍(long)完美服務(wu)，任(ren)何一(yi)個環(huan)節(jie)若有服務(wu)不(bu)(bu)周便會使(shi)燃氣熱(re)(re)水(shui)(shui)(shui)器(qi)(qi)(qi)點不(bu)(bu)著火(huo)。

4、機械故障

主(zhu)要有水(shui)氣(qi)(qi)聯動(dong)(dong)(dong)(dong)裝(zhuang)置(zhi)、風機.水(shui)氣(qi)(qi)聯動(dong)(dong)(dong)(dong)裝(zhuang)置(zhi)主(zhu)要由(you)水(shui)閥內部水(shui)壓(ya)提供動(dong)(dong)(dong)(dong)力,推動(dong)(dong)(dong)(dong)聯動(dong)(dong)(dong)(dong)桿,同時打(da)(da)開(kai)電路(lu)部分和其中一級(ji)燃氣(qi)(qi)密封通道,若(ruo)(ruo)水(shui)氣(qi)(qi)聯動(dong)(dong)(dong)(dong)裝(zhuang)置(zhi)出(chu)現故障整個電路(lu)部分都沒辦法工作(zuo),同樣不打(da)(da)火水(shui)不熱的(de);風機部分若(ruo)(ruo)因(yin)風葉卡死或電機轉速慢達(da)不到(dao)風壓(ya)檢(jian)測開(kai)關(guan)的(de)啟(qi)動(dong)(dong)(dong)(dong)壓(ya)力,脈(mo)沖點火器無法得風壓(ya)檢(jian)測開(kai)關(guan)的(de)信號,也會使燃氣(qi)(qi)熱水(shui)器點不著(zhu)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(zhe)四(si)步檢(jian)查，其故障(zhang)原(yuan)因自然就明了了，以上維(wei)(wei)(wei)修(xiu)檢(jian)查步驟熱水(shui)器(qi)維(wei)(wei)(wei)修(xiu)人(ren)員可(ke)以參照進(jin)行操(cao)作，另(ling)外(wai)小編在此建(jian)議(yi)廣大用戶：燃氣行業屬于危險行業，非熱水(shui)器(qi)維(wei)(wei)(wei)修(xiu)人(ren)員請勿自行維(wei)(wei)(wei)修(xiu)熱水(shui)器(qi)，維(wei)(wei)(wei)修(xiu)時應(ying)報(bao)各品牌的專業售后維(wei)(wei)(wei)修(xiu)。
