一、太陽能熱水器電磁閥工作原理

太陽能電磁閥控制熱水器加水的原理用通俗的工程語言來說就是，一個自動上水的控制電路很簡單，可以在太陽能加個液位電極（用鍍鋅圓鋼或不銹鋼都可以），在兩根電極上串接上24VDC電源正極，外接一個24VDC繼電器，用繼電器控制電磁閥。

兩根電(dian)(dian)(dian)(dian)(dian)極(ji)一長(chang)（下(xia)限(xian)）一短（上(shang)(shang)限(xian)），當水(shui)位(wei)(wei)在(zai)下(xia)限(xian)時，也就是水(shui)沒(mei)有漫(man)過(guo)(guo)長(chang)電(dian)(dian)(dian)(dian)(dian)極(ji)，繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)不得(de)電(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)磁(ci)閥打開(kai)(kai)(kai)(kai)上(shang)(shang)水(shui)。當水(shui)位(wei)(wei)上(shang)(shang)升到上(shang)(shang)限(xian)兩根電(dian)(dian)(dian)(dian)(dian)極(ji)通(tong)過(guo)(guo)水(shui)導(dao)通(tong)，繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)得(de)電(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)磁(ci)閥關閉，停(ting)止上(shang)(shang)水(shui)。還有你(ni)可以用浮(fu)子開(kai)(kai)(kai)(kai)關控(kong)制自(zi)動(dong)上(shang)(shang)水(shui)，這樣電(dian)(dian)(dian)(dian)(dian)路(lu)簡便，只要將電(dian)(dian)(dian)(dian)(dian)源串在(zai)浮(fu)子開(kai)(kai)(kai)(kai)關上(shang)(shang)，通(tong)過(guo)(guo)開(kai)(kai)(kai)(kai)關控(kong)制繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)，再(zai)由繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)控(kong)制電(dian)(dian)(dian)(dian)(dian)磁(ci)閥。原理水(shui)面達(da)到上(shang)(shang)限(xian)浮(fu)子開(kai)(kai)(kai)(kai)關斷開(kai)(kai)(kai)(kai)，繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)失電(dian)(dian)(dian)(dian)(dian)斷開(kai)(kai)(kai)(kai)電(dian)(dian)(dian)(dian)(dian)磁(ci)閥，下(xia)限(xian)浮(fu)子開(kai)(kai)(kai)(kai)關接通(tong)繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)得(de)電(dian)(dian)(dian)(dian)(dian)接通(tong)電(dian)(dian)(dian)(dian)(dian)磁(ci)閥。

二、太陽能熱水器電磁閥怎么安裝

1、安(an)裝前先沖洗管路，將雜質沖洗干凈。

2、若是水塔供(gong)水，請選(xuan)擇(ze)與(yu)水壓相適配電磁(ci)閥(fa)。以免(mian)電磁(ci)閥(fa)不(bu)能(neng)上水或流量過(guo)小。

3、檢查電(dian)磁閥標識電(dian)壓是否(fou)與控制電(dian)源輸出(chu)電(dian)壓一致，檢查過濾網是否(fou)完整、閥體(ti)各部位(wei)是否(fou)無破損。

4、將(jiang)測控儀配套的電磁(ci)閥(fa)(fa)(fa)安裝在冷(leng)熱水管相通的管路上。電磁(ci)閥(fa)(fa)(fa)有濾網端為(wei)進水口(kou)，閥(fa)(fa)(fa)體(ti)上箭頭與(yu)上水水流(liu)方向相同，不(bu)可接反(fan)，電磁(ci)閥(fa)(fa)(fa)閥(fa)(fa)(fa)體(ti)朝上并處(chu)于水平位置安裝。

5、安裝好(hao)后(hou)，通電(dian)檢(jian)測。

三、太陽能熱水器電磁閥安裝注意事項

電磁閥的(de)(de)作(zuo)用(yong)是使(shi)(shi)管(guan)道中的(de)(de)止回或定向流動(dong)，電(dian)磁(ci)(ci)閥(fa)(fa)在給太(tai)陽(yang)能(neng)(neng)熱水(shui)(shui)(shui)(shui)器上(shang)水(shui)(shui)(shui)(shui)的(de)(de)時(shi)候它(ta)就打開，讓(rang)冷(leng)(leng)水(shui)(shui)(shui)(shui)進(jin)入水(shui)(shui)(shui)(shui)箱(xiang)當中，當停止上(shang)水(shui)(shui)(shui)(shui)的(de)(de)時(shi)候電(dian)磁(ci)(ci)閥(fa)(fa)就關閉(bi)了，那么太(tai)陽(yang)能(neng)(neng)水(shui)(shui)(shui)(shui)箱(xiang)中水(shui)(shui)(shui)(shui)就不(bu)能(neng)(neng)通(tong)過電(dian)磁(ci)(ci)閥(fa)(fa)倒流回冷(leng)(leng)水(shui)(shui)(shui)(shui)管(guan)里。如果(guo)當使(shi)(shi)用(yong)熱水(shui)(shui)(shui)(shui)器里的(de)(de)水(shui)(shui)(shui)(shui)的(de)(de)時(shi)候，電(dian)磁(ci)(ci)閥(fa)(fa)依(yi)然是關閉(bi)的(de)(de)，那么水(shui)(shui)(shui)(shui)就只能(neng)(neng)流到(dao)放(fang)熱水(shui)(shui)(shui)(shui)的(de)(de)管(guan)道里而不(bu)能(neng)(neng)流到(dao)冷(leng)(leng)水(shui)(shui)(shui)(shui)管(guan)里。通(tong)常(chang)來說(shuo)電(dian)磁(ci)(ci)閥(fa)(fa)和(he)太(tai)陽(yang)能(neng)(neng)儀(yi)表(biao)是搭配使(shi)(shi)用(yong)的(de)(de)，應(ying)該是全自動(dong)控制的(de)(de)，所以(yi)在試用(yong)太(tai)陽(yang)能(neng)(neng)熱水(shui)(shui)(shui)(shui)器的(de)(de)時(shi)候是不(bu)需要去單獨(du)控制電(dian)磁(ci)(ci)閥(fa)(fa)的(de)(de)。

太陽能(neng)(neng)電(dian)磁閥(fa)分(fen)為有壓和無(wu)壓兩種(zhong)，如(ru)果冷(leng)水(shui)(shui)水(shui)(shui)壓比較小的話最(zui)好是選擇無(wu)壓閥(fa)，否(fou)則(ze)電(dian)磁閥(fa)可(ke)能(neng)(neng)打不(bu)開，就(jiu)不(bu)能(neng)(neng)正(zheng)常上水(shui)(shui)；如(ru)果水(shui)(shui)水(shui)(shui)壓較大的話，就(jiu)選擇有壓閥(fa)，否(fou)則(ze)電(dian)磁閥(fa)可(ke)能(neng)(neng)不(bu)能(neng)(neng)止回，也就(jiu)是說熱水(shui)(shui)器(qi)(qi)里的水(shui)(shui)可(ke)能(neng)(neng)會倒流(liu)到冷(leng)水(shui)(shui)管當中或者電(dian)磁閥(fa)無(wu)法關(guan)閉(bi)，造成熱水(shui)(shui)器(qi)(qi)溫度升(sheng)不(bu)上去。

四、太陽能熱水器電磁閥故障維修方法

1、故障表現：在通電了的情況下不運作

原因分(fen)析：出(chu)現這(zhe)種情況(kuang)的可能(neng)性比(bi)較多，有可能(neng)是(shi)電源(yuan)處的接線(xian)接觸不(bu)良所導(dao)致，可能(neng)是(shi)在(zai)電源(yuan)電壓的變(bian)動幅度過大(da)導(dao)致電線(xian)燒壞(huai)或者是(shi)短(duan)路。解決方(fang)法(fa)：注意檢(jian)查排除，將電源(yuan)線(xian)接好，并且調(diao)整電壓，使其(qi)保持在(zai)一個穩定(ding)的范圍內。可以(yi)更換線(xian)圈(quan)。

2、故障表現：在開閥的時候，流體不能夠通過

原因分(fen)析(xi)及(ji)對應方法(fa)：出現這(zhe)種故障的(de)情(qing)況也是(shi)非常(chang)(chang)的(de)多，一是(shi)流體的(de)壓(ya)力(li)或(huo)(huo)者是(shi)其(qi)工(gong)作的(de)壓(ya)力(li)差不(bu)符合正常(chang)(chang)的(de)運作范(fan)圍(wei)，這(zhe)時就需要(yao)調整(zheng)壓(ya)力(li)或(huo)(huo)者工(gong)作壓(ya)差;二是(shi)在閥芯或(huo)(huo)者是(shi)在動鐵芯的(de)地方混入了大量的(de)污(wu)垢雜質，這(zhe)時需要(yao)將其(qi)內(nei)部清(qing)理干凈即可(ke);三是(shi)閥前過濾(lv)器堵塞了，這(zhe)時將過濾(lv)器清(qing)洗(xi)干凈即可(ke)。

3、故障表現：在開機運轉的時候，太陽能熱水器電磁閥出現了外漏情況

原因分(fen)析及對應方法(fa)：一(yi)種(zhong)(zhong)是(shi)管道的(de)連接(jie)處沒有(you)安裝牢固，出(chu)現了松動情況，這時將螺栓擰緊(jin)即可。一(yi)種(zhong)(zhong)是(shi)管道的(de)連接(jie)外密封件(jian)出(chu)現了損壞，這種(zhong)(zhong)情況只能(neng)重新更(geng)換一(yi)個密封件(jian)。

4、故障表現：在通電運轉的時候，噪音特別的大

原因分(fen)析及對(dui)應方(fang)法：一是緊固件(jian)的(de)地方(fang)出(chu)現(xian)了松動(dong)，擰(ning)緊即(ji)可。二是電壓(ya)的(de)波動(dong)幅度太大(da)，超過了允許的(de)范圍，這時調整電壓(ya)到正(zheng)常(chang)運(yun)轉的(de)范圍即(ji)可。
