一、蒸汽發生器常見故障及處理
蒸汽發生器主要由兩大(da)部(bu)分組成,即加(jia)熱(re)(re)(re)部(bu)分,注(zhu)(zhu)水(shui)部(bu)分。按(an)其控(kong)制(zhi)(zhi)來分,加(jia)熱(re)(re)(re)部(bu)分又分電接點壓力表控(kong)制(zhi)(zhi)加(jia)熱(re)(re)(re)(這(zhe)種蒸汽發生(sheng)器都(dou)裝有(you)控(kong)制(zhi)(zhi)線(xian)路板)和壓力控(kong)制(zhi)(zhi)器控(kong)制(zhi)(zhi)加(jia)熱(re)(re)(re)。注(zhu)(zhu)水(shui)部(bu)分又分人工注(zhu)(zhu)水(shui)和水(shui)泵注(zhu)(zhu)水(shui)兩種。
1、注水部分的故障
(1)檢查水泵電機有無電源或缺相,令其正常。
(2)檢查水泵繼(ji)(ji)電(dian)器有無電(dian)源,令其正常。線(xian)路板無輸出電(dian)源給繼(ji)(ji)電(dian)器線(xian)圈,更換(huan)線(xian)路板。
(3)檢查高水位電(dian)和外殼是否(fou)接好(hao),端點是否(fou)銹(xiu)蝕,令其正常。
(4)檢查水(shui)泵(beng)壓力(li)和電機轉速,修(xiu)理水(shui)泵(beng)或更換電機(水(shui)泵(beng)電機功率不小于(yu)550W)。
(5)凡是使用浮(fu)(fu)漂液(ye)位控(kong)(kong)制器注(zhu)水的蒸汽發生器,除檢查電源外(wai),要檢查浮(fu)(fu)漂液(ye)位控(kong)(kong)制器低水位觸點是否(fou)銹蝕(shi)或接反,修(xiu)復(fu)后(hou)正常(chang)。
2、加熱部分常見故障
采用(yong)壓力(li)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)器(qi)(qi)(qi)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)的(de)蒸(zheng)汽發(fa)生器(qi)(qi)(qi),因為沒(mei)有水(shui)位(wei)顯示,沒(mei)有線(xian)路板控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi),它的(de)加熱(re)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)主要是(shi)通(tong)過浮(fu)(fu)漂(piao)(piao)液位(wei)器(qi)(qi)(qi)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)。當水(shui)位(wei)適量時,浮(fu)(fu)漂(piao)(piao)漂(piao)(piao)浮(fu)(fu)點(dian)接通(tong)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)電(dian)壓,使(shi)交流(liu)接觸器(qi)(qi)(qi)工作,開始加熱(re)。這(zhe)種蒸(zheng)汽發(fa)生器(qi)(qi)(qi)結構簡單,目(mu)前市(shi)場使(shi)用(yong)流(liu)通(tong)較多。這(zhe)種蒸(zheng)汽發(fa)生器(qi)(qi)(qi)常見的(de)不加熱(re)故障,大都是(shi)出現在浮(fu)(fu)漂(piao)(piao)液位(wei)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)器(qi)(qi)(qi)上(shang)。檢(jian)(jian)查(cha)浮(fu)(fu)漂(piao)(piao)液位(wei)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)器(qi)(qi)(qi)外部接線(xian),上(shang)下點(dian)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)線(xian)是(shi)否接對(dui),然后拆出浮(fu)(fu)漂(piao)(piao)液位(wei)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)器(qi)(qi)(qi),看其(qi)漂(piao)(piao)浮(fu)(fu)是(shi)否靈活。這(zhe)時可(ke)以(yi)用(yong)手動(dong),用(yong)表量其(qi)上(shang)下控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)點(dian)是(shi)否能接通(tong)。檢(jian)(jian)查(cha)后都正常,再檢(jian)(jian)查(cha)浮(fu)(fu)漂(piao)(piao)罐(guan)有沒(mei)有進(jin)(jin)水(shui)。浮(fu)(fu)漂(piao)(piao)罐(guan)進(jin)(jin)水(shui),換浮(fu)(fu)漂(piao)(piao)罐(guan),故障就排除了。
二、蒸汽發生器怎么保養
1、使用前要需要檢查是否有打開進水閥,以免蒸汽發生器發生干燒狀況。
2、每天(tian)工作完成后(hou),要對蒸汽發生器進(jin)行排污。
3、排污完(wan)后開啟所(suo)有(you)的(de)閥(fa)門,并且關閉電(dian)源。
4、按時間加入除垢劑(ji)和中和劑(ji),進(jin)行爐內的(de)除垢。
5、要定時檢查蒸汽發(fa)生的線(xian)路,以(yi)免發(fa)生線(xian)路老化(hua),如有老化(hua)現象需進行(xing)更換。
6、定期(qi)徹底清理一次蒸汽發生器爐內的(de)水(shui)垢,以免(mian)水(shui)垢的(de)積累。
