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(gen)電(dian)(dian)(dian)(dian)(dian)極一長（下(xia)限(xian)）一短（上(shang)(shang)(shang)限(xian)），當水(shui)(shui)(shui)(shui)位在(zai)下(xia)限(xian)時，也(ye)就是水(shui)(shui)(shui)(shui)沒有漫過長電(dian)(dian)(dian)(dian)(dian)極，繼電(dian)(dian)(dian)(dian)(dian)器(qi)不得(de)電(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)磁(ci)閥打開上(shang)(shang)(shang)水(shui)(shui)(shui)(shui)。當水(shui)(shui)(shui)(shui)位上(shang)(shang)(shang)升到上(shang)(shang)(shang)限(xian)兩根(gen)電(dian)(dian)(dian)(dian)(dian)極通(tong)(tong)過水(shui)(shui)(shui)(shui)導通(tong)(tong)，繼電(dian)(dian)(dian)(dian)(dian)器(qi)得(de)電(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)磁(ci)閥關(guan)閉，停止上(shang)(shang)(shang)水(shui)(shui)(shui)(shui)。還(huan)有你可以用浮(fu)(fu)子(zi)開關(guan)控制自動上(shang)(shang)(shang)水(shui)(shui)(shui)(shui)，這(zhe)樣電(dian)(dian)(dian)(dian)(dian)路簡便，只要將(jiang)電(dian)(dian)(dian)(dian)(dian)源串在(zai)浮(fu)(fu)子(zi)開關(guan)上(shang)(shang)(shang)，通(tong)(tong)過開關(guan)控制繼電(dian)(dian)(dian)(dian)(dian)器(qi)，再由繼電(dian)(dian)(dian)(dian)(dian)器(qi)控制電(dian)(dian)(dian)(dian)(dian)磁(ci)閥。原理水(shui)(shui)(shui)(shui)面(mian)達到上(shang)(shang)(shang)限(xian)浮(fu)(fu)子(zi)開關(guan)斷(duan)開，繼電(dian)(dian)(dian)(dian)(dian)器(qi)失(shi)電(dian)(dian)(dian)(dian)(dian)斷(duan)開電(dian)(dian)(dian)(dian)(dian)磁(ci)閥，下(xia)限(xian)浮(fu)(fu)子(zi)開關(guan)接通(tong)(tong)繼電(dian)(dian)(dian)(dian)(dian)器(qi)得(de)電(dian)(dian)(dian)(dian)(dian)接通(tong)(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(xian)沖洗管路(lu)，將(jiang)雜質沖洗干凈。

2、若(ruo)是(shi)水塔供水，請選(xuan)擇與(yu)水壓(ya)相適配電磁(ci)閥。以免電磁(ci)閥不(bu)能(neng)上(shang)水或流量過小。

3、檢查電磁閥標識電壓是否(fou)(fou)與控制電源輸出電壓一致，檢查過(guo)濾網(wang)是否(fou)(fou)完整、閥體各(ge)部位(wei)是否(fou)(fou)無破損。

4、將測控儀配(pei)套的電磁(ci)閥(fa)(fa)安裝(zhuang)在冷熱水管(guan)相通的管(guan)路上(shang)。電磁(ci)閥(fa)(fa)有濾網端為進水口，閥(fa)(fa)體上(shang)箭頭(tou)與上(shang)水水流(liu)方向相同(tong)，不(bu)可(ke)接反，電磁(ci)閥(fa)(fa)閥(fa)(fa)體朝(chao)上(shang)并處于水平位置安裝(zhuang)。

5、安(an)裝好后，通電檢測。

三、太陽能熱水器電磁閥安裝注意事項

電磁閥的(de)作用是(shi)使管(guan)道中的(de)止回(hui)或定向(xiang)流(liu)動，電(dian)磁(ci)(ci)閥(fa)(fa)(fa)在給(gei)太陽(yang)能(neng)(neng)熱水(shui)(shui)(shui)(shui)器(qi)(qi)上水(shui)(shui)(shui)(shui)的(de)時(shi)候它就打開(kai)，讓冷水(shui)(shui)(shui)(shui)進(jin)入(ru)水(shui)(shui)(shui)(shui)箱當中，當停止上水(shui)(shui)(shui)(shui)的(de)時(shi)候電(dian)磁(ci)(ci)閥(fa)(fa)(fa)就關閉了，那(nei)么太陽(yang)能(neng)(neng)水(shui)(shui)(shui)(shui)箱中水(shui)(shui)(shui)(shui)就不(bu)(bu)能(neng)(neng)通過電(dian)磁(ci)(ci)閥(fa)(fa)(fa)倒(dao)流(liu)回(hui)冷水(shui)(shui)(shui)(shui)管(guan)里(li)。如(ru)果當使用熱水(shui)(shui)(shui)(shui)器(qi)(qi)里(li)的(de)水(shui)(shui)(shui)(shui)的(de)時(shi)候，電(dian)磁(ci)(ci)閥(fa)(fa)(fa)依然是(shi)關閉的(de)，那(nei)么水(shui)(shui)(shui)(shui)就只能(neng)(neng)流(liu)到放熱水(shui)(shui)(shui)(shui)的(de)管(guan)道里(li)而不(bu)(bu)能(neng)(neng)流(liu)到冷水(shui)(shui)(shui)(shui)管(guan)里(li)。通常來說電(dian)磁(ci)(ci)閥(fa)(fa)(fa)和太陽(yang)能(neng)(neng)儀表是(shi)搭(da)配使用的(de)，應該是(shi)全自動控制(zhi)(zhi)的(de)，所以在試用太陽(yang)能(neng)(neng)熱水(shui)(shui)(shui)(shui)器(qi)(qi)的(de)時(shi)候是(shi)不(bu)(bu)需要(yao)去單獨控制(zhi)(zhi)電(dian)磁(ci)(ci)閥(fa)(fa)(fa)的(de)。

太(tai)陽能(neng)(neng)電磁閥(fa)分為有(you)壓(ya)和無(wu)(wu)壓(ya)兩種，如(ru)果(guo)冷水(shui)(shui)(shui)水(shui)(shui)(shui)壓(ya)比較小的(de)話最好是選(xuan)擇無(wu)(wu)壓(ya)閥(fa)，否則電磁閥(fa)可能(neng)(neng)打不(bu)(bu)開，就不(bu)(bu)能(neng)(neng)正常上水(shui)(shui)(shui)；如(ru)果(guo)水(shui)(shui)(shui)水(shui)(shui)(shui)壓(ya)較大的(de)話，就選(xuan)擇有(you)壓(ya)閥(fa)，否則電磁閥(fa)可能(neng)(neng)不(bu)(bu)能(neng)(neng)止回，也就是說熱(re)水(shui)(shui)(shui)器(qi)里的(de)水(shui)(shui)(shui)可能(neng)(neng)會(hui)倒流到冷水(shui)(shui)(shui)管當中(zhong)或者(zhe)電磁閥(fa)無(wu)(wu)法關閉，造成熱(re)水(shui)(shui)(shui)器(qi)溫(wen)度(du)升(sheng)不(bu)(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

原因分析：出現這種情況的(de)可(ke)能性比較多，有可(ke)能是電(dian)源處(chu)的(de)接(jie)(jie)線接(jie)(jie)觸不良所導(dao)致，可(ke)能是在電(dian)源電(dian)壓的(de)變動幅度過大導(dao)致電(dian)線燒(shao)壞或者(zhe)是短路。解決方法：注意檢查排除(chu)，將電(dian)源線接(jie)(jie)好，并(bing)且調整電(dian)壓，使其保(bao)持在一個穩定的(de)范(fan)圍(wei)內。可(ke)以(yi)更換(huan)線圈。

2、故障表現：在開閥的時候，流體不能夠通過

原因(yin)分析及對應(ying)方(fang)法：出現(xian)這種故障(zhang)的(de)(de)情況(kuang)也是(shi)(shi)非常(chang)的(de)(de)多，一是(shi)(shi)流體的(de)(de)壓(ya)力或(huo)者(zhe)是(shi)(shi)其工作(zuo)的(de)(de)壓(ya)力差不符合正常(chang)的(de)(de)運作(zuo)范(fan)圍，這時(shi)就需要調整壓(ya)力或(huo)者(zhe)工作(zuo)壓(ya)差;二是(shi)(shi)在(zai)閥芯(xin)或(huo)者(zhe)是(shi)(shi)在(zai)動(dong)鐵芯(xin)的(de)(de)地方(fang)混入了(le)大(da)量(liang)的(de)(de)污垢雜(za)質，這時(shi)需要將其內部(bu)清理干凈(jing)即可(ke);三是(shi)(shi)閥前(qian)過(guo)濾(lv)器堵塞了(le)，這時(shi)將過(guo)濾(lv)器清洗干凈(jing)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(yin)分析及對應方(fang)法(fa)：一(yi)種(zhong)是管(guan)道的(de)連接(jie)處(chu)沒有安裝牢固，出現了松動情況(kuang)，這時將螺栓擰(ning)緊(jin)即(ji)可。一(yi)種(zhong)是管(guan)道的(de)連接(jie)外密封件出現了損(sun)壞，這種(zhong)情況(kuang)只能重新(xin)更(geng)換(huan)一(yi)個密封件。

4、故障表現：在通電運轉的時候，噪音特別的大

原因(yin)分析及對應方法：一是(shi)緊(jin)固(gu)件的地方出現了松動(dong)，擰緊(jin)即可。二是(shi)電(dian)壓的波動(dong)幅度太大(da)，超過了允(yun)許的范圍，這(zhe)時(shi)調整電(dian)壓到正常(chang)運(yun)轉的范圍即可。
