燃(ran)油燃(ran)氣(qi)燃(ran)燒(shao)(shao)機故(gu)(gu)障(zhang)排除(chu)方(fang)法(fa)及重點(dian),點(dian)火(huo)故(gu)(gu)障(zhang)正(zheng)常(chang)(chang)條(tiao)件下,連(lian)續啟動(dong)三(san)次燃(ran)燒(shao)(shao)器(qi),沒有點(dian)燃(ran)燃(ran)燒(shao)(shao)應(ying)(ying)判斷為(wei)點(dian)火(huo)故(gu)(gu)障(zhang),需(xu)要(yao)進(jin)行相應(ying)(ying)檢(jian)(jian)查來(lai)排除(chu)故(gu)(gu)障(zhang)。正(zheng)常(chang)(chang)條(tiao)件下,連(lian)續啟動(dong)三(san)次燃(ran)燒(shao)(shao)器(qi),沒有點(dian)燃(ran)燃(ran)燒(shao)(shao)應(ying)(ying)判斷為(wei)點(dian)火(huo)故(gu)(gu)障(zhang),需(xu)要(yao)進(jin)行相應(ying)(ying)檢(jian)(jian)查來(lai)排除(chu)故(gu)(gu)障(zhang)。檢(jian)(jian)查天然(ran)氣(qi)的壓力是否正(zheng)常(chang)(chang)保(bao)持在3-5kpa,過(guo)高或過(guo)低(di)均會出現(xian)(xian)點(dian)不著火(huo)現(xian)(xian)象。處理方(fang)法(fa);調(diao)節天然(ran)氣(qi)調(diao)壓閥,進(jin)行壓力設定。
檢查風門(men)大小(xiao)(xiao),風門(men)在偏大時(shi)(shi)(shi)(shi)容易出現(xian)(xian)多(duo)次點火(huo)(huo)(huo)(huo)不著的(de)現(xian)(xian)象,處理方法(fa);將(jiang)風門(men)適當的(de)調(diao)(diao)(diao)小(xiao)(xiao),但不可以完全關閉。點火(huo)(huo)(huo)(huo)變壓器不打(da)火(huo)(huo)(huo)(huo),或點火(huo)(huo)(huo)(huo)電(dian)(dian)極(ji)太臟位置不對時(shi)(shi)(shi)(shi),均會(hui)出現(xian)(xian)點火(huo)(huo)(huo)(huo)故(gu)障(zhang)。處理方法(fa);測試點火(huo)(huo)(huo)(huo)變壓器是(shi)否點火(huo)(huo)(huo)(huo),清理點火(huo)(huo)(huo)(huo)電(dian)(dian)極(ji),調(diao)(diao)(diao)整點火(huo)(huo)(huo)(huo)間(jian)隙保持2-3mm。正(zheng)常點火(huo)(huo)(huo)(huo)時(shi)(shi)(shi)(shi)閥(fa)組會(hui)及時(shi)(shi)(shi)(shi)地開(kai)啟,并能聽(ting)到開(kai)啟的(de)聲音,打(da)不開(kai)時(shi)(shi)(shi)(shi)不會(hui)建立(li)火(huo)(huo)(huo)(huo)焰,處理方法(fa);檢查閥(fa)組線(xian)圈(quan),調(diao)(diao)(diao)節閥(fa)的(de)開(kai)啟度。
所有點(dian)火(huo)程序由(you)控(kong)(kong)制(zhi)器(qi)(qi)發出(chu),控(kong)(kong)制(zhi)器(qi)(qi)損(sun)壞,不(bu)能正常點(dian)火(huo)。處(chu)(chu)理方法(fa);更換控(kong)(kong)制(zhi)器(qi)(qi)。燃燒(shao)器(qi)(qi)正常運行(xing)燃燒(shao)時,突(tu)然滅火(huo),為熄火(huo)故障。氣源(yuan)不(bu)穩造成火(huo)焰(yan)波動后,滅火(huo),處(chu)(chu)理方法(fa);調整(zheng)壓力(li),重新啟動。運行(xing)時火(huo)焰(yan)檢測探針(zhen)接(jie)地(di),或太臟時測不(bu)到正常的火(huo)焰(yan),出(chu)現熄火(huo)。處(chu)(chu)理方法(fa);調整(zheng)探針(zhen)位置,清理探針(zhen)表面。重新啟動。
燃(ran)氣(qi)燃(ran)燒機(ji)故障(zhang)排除方(fang)法(fa)及重點,電源(yuan)不穩(wen)或(huo)缺相,造成(cheng)過程中熄火。處(chu)理方(fang)法(fa);聯系(xi)電工(gong)檢查電源(yuan)及接線。按下(xia)啟動(dong)按鈕長時(shi)間燃(ran)燒器(qi)不啟動(dong)。外接溫度或(huo)壓力控(kong)制沒有(you)到(dao)(dao)達啟動(dong)下(xia)限(xian);檢查溫度或(huo)壓力設定值。氣(qi)壓過高或(huo)過低(di)時(shi),風(feng)壓開關常閉(bi)沒有(you)閉(bi)合時(shi),風(feng)門機(ji)構沒到(dao)(dao)位時(shi),均(jun)會出現,逐步進行檢查。
