燃氣熱水器打不著火怎么辦

燃氣熱水器打(da)不著火(huo)是(shi)燃(ran)氣熱水(shui)器(qi)(qi)(qi)故(gu)障(zhang)(zhang)率(lv)最高的(de)故(gu)障(zhang)(zhang)現(xian)象，現(xian)在(zai)以最普遍強排(pai)式或平衡式燃(ran)氣熱水(shui)器(qi)(qi)(qi)為例：具體(ti)現(xian)象有(you)(you)排(pai)風(feng)機(ji)轉動正(zheng)常，沒有(you)(you)電火(huo)花(hua)打(da)火(huo)的(de)聲音(yin)；有(you)(you)電火(huo)花(hua)打(da)火(huo)的(de)聲音(yin),但不能(neng)打(da)著火(huo)；有(you)(you)的(de)是(shi)開啟燃(ran)氣熱水(shui)器(qi)(qi)(qi)時機(ji)內沒有(you)(you)任何(he)反應(ying)，電源指(zhi)示燈都不亮的(de)情(qing)況(kuang)。

這些是通常熱水器打不(bu)著火所表現的具(ju)體現象(xiang)。我們把燃氣熱水器分(fen)四部(bu)分(fen)來具(ju)體分(fen)析維修(xiu)熱水器便可很容(rong)易的快速(su)找(zhao)到(dao)熱水器打不(bu)著火的原因和(he)故(gu)障點。

燃氣熱水器打不著火原因

1、燃氣通路（氣路）

無論是(shi)(shi)(shi)使(shi)(shi)用(yong)(yong)天(tian)然氣(qi)(qi)(qi)(qi)、液化石(shi)油氣(qi)(qi)(qi)(qi)、人工煤氣(qi)(qi)(qi)(qi)的(de)(de)用(yong)(yong)戶，燃(ran)氣(qi)(qi)(qi)(qi)通路(lu)(lu)是(shi)(shi)(shi)首先要(yao)檢查(cha)的(de)(de)一(yi)步，這一(yi)部(bu)分(fen)包括進(jin)(jin)氣(qi)(qi)(qi)(qi)咀、電(dian)(dian)磁(ci)閥(fa)、水(shui)氣(qi)(qi)(qi)(qi)聯動(dong)密封閥(fa)、燃(ran)氣(qi)(qi)(qi)(qi)分(fen)氣(qi)(qi)(qi)(qi)管、燃(ran)氣(qi)(qi)(qi)(qi)噴(pen)咀、燃(ran)燒(shao)器(qi)或(huo)(huo)(huo)俗稱火排，這些造(zao)(zao)成燃(ran)氣(qi)(qi)(qi)(qi)熱(re)(re)(re)水(shui)器(qi)打(da)(da)不著(zhu)(zhu)火主要(yao)是(shi)(shi)(shi)因為堵(du)塞(sai)(sai)或(huo)(huo)(huo)不通暢，進(jin)(jin)氣(qi)(qi)(qi)(qi)咀處有一(yi)過濾網，用(yong)(yong)于過濾燃(ran)氣(qi)(qi)(qi)(qi)雜質(zhi)和燃(ran)氣(qi)(qi)(qi)(qi)異物(wu)進(jin)(jin)入燃(ran)氣(qi)(qi)(qi)(qi)通道內部(bu)；電(dian)(dian)磁(ci)閥(fa)在不通電(dian)(dian)時的(de)(de)自然狀態下是(shi)(shi)(shi)將(jiang)(jiang)燃(ran)氣(qi)(qi)(qi)(qi)通路(lu)(lu)關(guan)閉的(de)(de)，它是(shi)(shi)(shi)靠(kao)熱(re)(re)(re)水(shui)器(qi)脈(mo)沖控(kong)制(zhi)器(qi)供(gong)電(dian)(dian)才(cai)將(jiang)(jiang)閥(fa)門打(da)(da)開(kai)通氣(qi)(qi)(qi)(qi)后才(cai)能使(shi)(shi)熱(re)(re)(re)水(shui)器(qi)點著(zhu)(zhu)火，這個位置的(de)(de)故(gu)障率極高，但通常不是(shi)(shi)(shi)電(dian)(dian)磁(ci)閥(fa)本身(shen)故(gu)障造(zao)(zao)成的(de)(de)，而多數(shu)是(shi)(shi)(shi)由(you)于它未(wei)能得到供(gong)電(dian)(dian)電(dian)(dian)壓而導致開(kai)不了閥(fa)，打(da)(da)不著(zhu)(zhu)火的(de)(de)；水(shui)氣(qi)(qi)(qi)(qi)聯動(dong)密封閥(fa)處造(zao)(zao)成打(da)(da)不著(zhu)(zhu)火的(de)(de)故(gu)障率極低;燃(ran)氣(qi)(qi)(qi)(qi)分(fen)氣(qi)(qi)(qi)(qi)管也(ye)很(hen)(hen)少(shao)見出(chu)故(gu)障;燃(ran)氣(qi)(qi)(qi)(qi)噴(pen)咀的(de)(de)孔徑很(hen)(hen)小(xiao)(xiao)，個別品(pin)牌的(de)(de)特殊機(ji)型有的(de)(de)比較大,比如(ru)林(lin)內、能率、松下、萬和、萬家(jia)樂下鼓風等機(ji)型,主要(yao)由(you)燃(ran)燒(shao)器(qi)的(de)(de)設計而定,因孔徑小(xiao)(xiao),所以稍灰塵可(ke)能會造(zao)(zao)成堵(du)塞(sai)(sai)造(zao)(zao)成火小(xiao)(xiao)而打(da)(da)不著(zhu)(zhu)火;燃(ran)燒(shao)器(qi)也(ye)容易造(zao)(zao)成堵(du)塞(sai)(sai),堵(du)塞(sai)(sai)物(wu)通常是(shi)(shi)(shi)蜘蛛網之類,這里的(de)(de)溫度和環境剛好適合做昆蟲的(de)(de)蝸居,如(ru)果熱(re)(re)(re)水(shui)器(qi)間(jian)隔一(yi)段時間(jian)未(wei)使(shi)(shi)用(yong)(yong),很(hen)(hen)可(ke)能這里就(jiu)(jiu)被它們占領了,到你(ni)下次使(shi)(shi)用(yong)(yong)就(jiu)(jiu)會發現(xian)火小(xiao)(xiao)或(huo)(huo)(huo)打(da)(da)不燃(ran)火的(de)(de)原因就(jiu)(jiu)在這里.

2、水路故障

燃氣熱水器水(shui)(shui)(shui)路故障主(zhu)要(yao)有進水(shui)(shui)(shui)口過(guo)濾網堵塞、水(shui)(shui)(shui)閥結(jie)垢(gou)、水(shui)(shui)(shui)箱銅(tong)管變形堵塞、水(shui)(shui)(shui)壓(ya)(ya)低等。它們造成燃(ran)氣熱(re)水(shui)(shui)(shui)器打不(bu)(bu)著火的共同點是熱(re)水(shui)(shui)(shui)器出(chu)水(shui)(shui)(shui)量(liang)會明顯(xian)減(jian)小,低至燃(ran)氣熱(re)水(shui)(shui)(shui)器的啟動(dong)壓(ya)(ya)力0.02MPa的水(shui)(shui)(shui)壓(ya)(ya)時就無法(fa)啟動(dong)熱(re)水(shui)(shui)(shui)器了(le)，老式(shi)(shi)強制(zhi)排氣式(shi)(shi)熱(re)水(shui)(shui)(shui)器這個現象很(hen)明顯(xian)，所以排除(chu)是否(fou)因(yin)(yin)為(wei)水(shui)(shui)(shui)路故障造成燃(ran)氣熱(re)水(shui)(shui)(shui)器打不(bu)(bu)起(qi)火的原因(yin)(yin)只需要(yao)觀察(cha)出(chu)水(shui)(shui)(shui)量(liang)或(huo)水(shui)(shui)(shui)壓(ya)(ya)是否(fou)過(guo)低即(ji)可(ke)，發現過(guo)低按前面(mian)講(jiang)的步驟進行(xing)即(ji)可(ke)。

3、電路系統故障

這一部(bu)分涉及的(de)配件較多,是(shi)燃氣熱水(shui)器(qi)打(da)不著火(huo)的(de)原因查找(zhao)之核心部(bu)分,包括漏電保插頭、熱水(shui)器(qi)電源(yuan)控制盒、脈沖點火(huo)器(qi)、電磁(ci)閥、風機啟動(dong)電容、風機、風壓檢測開(kai)關、微動(dong)開(kai)關或(huo)水(shui)流傳感器(qi)開(kai)關、點火(huo)針、感應針、冷熱水(shui)開(kai)關。

燃氣熱水器電(dian)(dian)路系統的(de)工(gong)作(zuo)原理和流程:首先微(wei)動(dong)開(kai)關(guan)(guan)(guan)被水閥頂桿推開(kai),微(wei)動(dong)開(kai)關(guan)(guan)(guan)閉合使(shi)(shi)脈沖(chong)點(dian)(dian)火(huo)(huo)器(qi)工(gong)作(zuo)（但不是在這個(ge)時(shi)(shi)候開(kai)始(shi)放(fang)(fang)電(dian)(dian)點(dian)(dian)火(huo)(huo)）,脈沖(chong)點(dian)(dian)火(huo)(huo)器(qi)發出(chu)(chu)工(gong)作(zuo)信號傳(chuan)送(song)至(zhi)熱水器(qi)電(dian)(dian)源(yuan)控制盒,進而(er)使(shi)(shi)繼電(dian)(dian)器(qi)工(gong)作(zuo)接(jie)通(tong)風(feng)(feng)機工(gong)作(zuo)電(dian)(dian)壓(ya),在啟動(dong)電(dian)(dian)容的(de)作(zuo)用(yong)壓(ya)風(feng)(feng)機開(kai)始(shi)轉動(dong),同時(shi)(shi)產生一(yi)個(ge)負風(feng)(feng)壓(ya)（有些熱水器(qi)設計時(shi)(shi)也有采用(yong)正風(feng)(feng)壓(ya)的(de)）,通(tong)過一(yi)條(tiao)連接(jie)到風(feng)(feng)壓(ya)檢(jian)測開(kai)關(guan)(guan)(guan)的(de)負壓(ya)管,使(shi)(shi)風(feng)(feng)壓(ya)檢(jian)測開(kai)關(guan)(guan)(guan)工(gong)作(zuo),此返回到脈沖(chong)點(dian)(dian)火(huo)(huo)器(qi)開(kai)始(shi)連續放(fang)(fang)電(dian)(dian)和延(yan)時(shi)(shi)2秒吸開(kai)電(dian)(dian)磁閥通(tong)氣(qi)即可點(dian)(dian)著(zhu)(zhu)火(huo)(huo),感(gan)應(ying)針感(gan)應(ying)到火(huo)(huo)焰正常后即通(tong)過脈沖(chong)給出(chu)(chu)電(dian)(dian)磁閥持續的(de)維持電(dian)(dian)壓(ya),使(shi)(shi)電(dian)(dian)磁閥保持在開(kai)啟狀(zhuang)態,燃(ran)燒器(qi)便可持續正常工(gong)作(zuo)。這是一(yi)條(tiao)龍完美服務(wu)，任何一(yi)個(ge)環節(jie)若有服務(wu)不周便會使(shi)(shi)燃(ran)氣(qi)熱水器(qi)點(dian)(dian)不著(zhu)(zhu)火(huo)(huo)。

4、機械故障

主要有水(shui)氣聯動(dong)(dong)(dong)裝置、風(feng)(feng)機.水(shui)氣聯動(dong)(dong)(dong)裝置主要由(you)水(shui)閥內部(bu)水(shui)壓提供動(dong)(dong)(dong)力(li),推動(dong)(dong)(dong)聯動(dong)(dong)(dong)桿,同(tong)時(shi)打開電(dian)路部(bu)分(fen)和其中一(yi)級燃氣密封通道(dao),若(ruo)水(shui)氣聯動(dong)(dong)(dong)裝置出(chu)現(xian)故障(zhang)整個電(dian)路部(bu)分(fen)都(dou)沒辦法工(gong)作,同(tong)樣不(bu)打火(huo)水(shui)不(bu)熱的;風(feng)(feng)機部(bu)分(fen)若(ruo)因風(feng)(feng)葉卡死或電(dian)機轉速(su)慢(man)達不(bu)到風(feng)(feng)壓檢測開關的啟動(dong)(dong)(dong)壓力(li),脈沖點火(huo)器無法得風(feng)(feng)壓檢測開關的信號,也會使燃氣熱水(shui)器點不(bu)著火(huo)。

從以上四步我們不難看出，燃氣熱水器打不著火時按這四步檢查，其故障(zhang)原因自(zi)然(ran)就明了了，以上(shang)維(wei)(wei)(wei)修(xiu)檢查步驟熱(re)水(shui)器維(wei)(wei)(wei)修(xiu)人(ren)員可以參照進(jin)行(xing)操作，另外小編在此建(jian)議廣大(da)用戶：燃氣(qi)行(xing)業(ye)(ye)屬于危險行(xing)業(ye)(ye)，非熱(re)水(shui)器維(wei)(wei)(wei)修(xiu)人(ren)員請勿自(zi)行(xing)維(wei)(wei)(wei)修(xiu)熱(re)水(shui)器，維(wei)(wei)(wei)修(xiu)時應報各品牌的專(zhuan)業(ye)(ye)售后維(wei)(wei)(wei)修(xiu)。
