电热蒸馏水器常见故障有:

(1)保(bao)险丝烧断

这种故障发生较多,肯(ken)定(ding)有(you)短路处。断(duan)电(dian)(dian)(dian)(dian)(dian)后可(ke)用万用电(dian)(dian)(dian)(dian)(dian)表电(dian)(dian)(dian)(dian)(dian)阻档测量各电(dian)(dian)(dian)(dian)(dian)热(re)(re)(re)管(guan)的电(dian)(dian)(dian)(dian)(dian)热(re)(re)(re)丝(si)是否接地(di),如(ru)(ru)接地(di),可(ke)把(ba)它的二头除去,这样可(ke)作为(wei)应急(ji)措施，蒸(zheng)(zheng)馏(liu)器仍然可(ke)用,只是功率减小。出水里相应减少。或者把(ba)它更换(huan)掉。如(ru)(ru)20升/时电(dian)(dian)(dian)(dian)(dian)热(re)(re)(re)蒸(zheng)(zheng)馏(liu)水器为(wei)6支3组,是二支并(bing)联使(shi)用的。有(you)时是断(duan)电(dian)(dian)(dian)(dian)(dian)时里电(dian)(dian)(dian)(dian)(dian)热(re)(re)(re)丝(si)不接地(di)。通(tong)电(dian)(dian)(dian)(dian)(dian)一段时间(jian)则接地(di)烧保(bao)险。这时可(ke)查一查水垢是否厚,如(ru)(ru)厚可(ke)**;**则可(ke)能是某(mou)支电(dian)(dian)(dian)(dian)(dian)热(re)(re)(re)管(guan)的电(dian)(dian)(dian)(dian)(dian)热(re)(re)(re)丝(si)通(tong)电(dian)(dian)(dian)(dian)(dian)后热(re)(re)(re)膨(peng)胀接地(di)所(suo)致(zhi)。

(2)合(he)上电源开关有响声及火(huo)花(hua)

合上电(dian)(dian)(dian)源开关有响(xiang)声及(ji)火花(hua)说明(ming)电(dian)(dian)(dian)气线路有短(duan)路或(huo)接(jie)触不，致(zhi)使电(dian)(dian)(dian)流(liu)太(tai)大。引起(qi)电(dian)(dian)(dian)流(liu)过(guo)大的(de)原因除了电(dian)(dian)(dian)热(re)管中电(dian)(dian)(dian)热(re)丝(si)接(jie)地外,还有可能(neng)是(shi)电(dian)(dian)(dian)热(re)管和蒸发锅之间(jian)漏(lou)水使电(dian)(dian)(dian)源接(jie)头(tou)处(chu)引起(qi)短(duan)路,或(huo)因潮湿(shi)造成电(dian)(dian)(dian)源接(jie)头(tou)处(chu)打火,导致(zhi)接(jie)线*缘板的(de)电(dian)(dian)(dian)阻变小。

(3)蒸馏水里减少

   随着使(shi)用(yong)时(shi)间的增加,电(dian)热管的水(shui)垢(gou)(gou)也(ye)慢慢增加,电(dian)热管的热里不(bu)易传出,蒸馏水(shui)出水(shui)里慢慢减少(shao),这时(shi)可(ke)用(yong)物理或(huo)化学(xue)方法**水(shui)垢(gou)(gou)。如出水(shui)里明(ming)显减少(shao)。肯定有(you)电(dian)热丝烧断,引起功率(lv)减少(shao),出水(shui)里减少(shao)，可(ke)用(yong)万(wan)用(yong)表(biao)查出烧断的电(dian)热管并(bing)更换。更换后(hou)应放水(shui)观察是否漏水(shui)或(huo)渗(shen)(shen)水(shui)，只有(you)无渗(shen)(shen)水(shui)后(hou)方可(ke)通电(dian)使(shi)用(yong)。
