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(liang)根電(dian)(dian)(dian)極一長(chang)（下(xia)限(xian)(xian)(xian)）一短（上限(xian)(xian)(xian)），當水(shui)(shui)(shui)位在下(xia)限(xian)(xian)(xian)時(shi)，也就是水(shui)(shui)(shui)沒有漫(man)過(guo)長(chang)電(dian)(dian)(dian)極，繼(ji)電(dian)(dian)(dian)器(qi)(qi)不得(de)電(dian)(dian)(dian)，電(dian)(dian)(dian)磁閥(fa)打開(kai)(kai)上水(shui)(shui)(shui)。當水(shui)(shui)(shui)位上升到上限(xian)(xian)(xian)兩(liang)根電(dian)(dian)(dian)極通(tong)(tong)過(guo)水(shui)(shui)(shui)導通(tong)(tong)，繼(ji)電(dian)(dian)(dian)器(qi)(qi)得(de)電(dian)(dian)(dian)，電(dian)(dian)(dian)磁閥(fa)關(guan)閉，停止(zhi)上水(shui)(shui)(shui)。還(huan)有你可以用浮(fu)子開(kai)(kai)關(guan)控(kong)制(zhi)自動上水(shui)(shui)(shui)，這(zhe)樣電(dian)(dian)(dian)路簡便，只要將(jiang)電(dian)(dian)(dian)源(yuan)串在浮(fu)子開(kai)(kai)關(guan)上，通(tong)(tong)過(guo)開(kai)(kai)關(guan)控(kong)制(zhi)繼(ji)電(dian)(dian)(dian)器(qi)(qi)，再(zai)由繼(ji)電(dian)(dian)(dian)器(qi)(qi)控(kong)制(zhi)電(dian)(dian)(dian)磁閥(fa)。原理(li)水(shui)(shui)(shui)面達到上限(xian)(xian)(xian)浮(fu)子開(kai)(kai)關(guan)斷開(kai)(kai)，繼(ji)電(dian)(dian)(dian)器(qi)(qi)失電(dian)(dian)(dian)斷開(kai)(kai)電(dian)(dian)(dian)磁閥(fa)，下(xia)限(xian)(xian)(xian)浮(fu)子開(kai)(kai)關(guan)接通(tong)(tong)繼(ji)電(dian)(dian)(dian)器(qi)(qi)得(de)電(dian)(dian)(dian)接通(tong)(tong)電(dian)(dian)(dian)磁閥(fa)。

二、太陽能熱水器電磁閥怎么安裝

1、安裝前先沖洗管(guan)路(lu)，將(jiang)雜質沖洗干凈。

2、若(ruo)是水(shui)(shui)塔(ta)供水(shui)(shui)，請選(xuan)擇與(yu)水(shui)(shui)壓相(xiang)適配電磁閥。以免電磁閥不能上水(shui)(shui)或(huo)流量過小。

3、檢(jian)查電(dian)(dian)(dian)磁閥(fa)標識電(dian)(dian)(dian)壓是否與控制電(dian)(dian)(dian)源輸出(chu)電(dian)(dian)(dian)壓一致，檢(jian)查過(guo)濾網是否完整、閥(fa)體各(ge)部(bu)位(wei)是否無破損。

4、將(jiang)測控(kong)儀配套的(de)(de)電(dian)磁閥(fa)安(an)(an)裝(zhuang)在冷熱水(shui)(shui)管相通的(de)(de)管路上(shang)(shang)(shang)。電(dian)磁閥(fa)有濾網端為進水(shui)(shui)口，閥(fa)體上(shang)(shang)(shang)箭(jian)頭(tou)與上(shang)(shang)(shang)水(shui)(shui)水(shui)(shui)流(liu)方向相同，不(bu)可接反，電(dian)磁閥(fa)閥(fa)體朝(chao)上(shang)(shang)(shang)并處于水(shui)(shui)平位置安(an)(an)裝(zhuang)。

5、安裝好后(hou)，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)(de)作用(yong)是(shi)(shi)(shi)(shi)使(shi)管道中的(de)(de)止(zhi)回或定向流(liu)(liu)動，電(dian)(dian)(dian)磁(ci)閥在給太(tai)陽(yang)(yang)能(neng)熱水器上水的(de)(de)時(shi)候(hou)它(ta)就打開，讓冷水進(jin)入(ru)水箱(xiang)當中，當停(ting)止(zhi)上水的(de)(de)時(shi)候(hou)電(dian)(dian)(dian)磁(ci)閥就關閉了，那(nei)么太(tai)陽(yang)(yang)能(neng)水箱(xiang)中水就不能(neng)通(tong)過電(dian)(dian)(dian)磁(ci)閥倒流(liu)(liu)回冷水管里(li)。如果當使(shi)用(yong)熱水器里(li)的(de)(de)水的(de)(de)時(shi)候(hou)，電(dian)(dian)(dian)磁(ci)閥依然是(shi)(shi)(shi)(shi)關閉的(de)(de)，那(nei)么水就只能(neng)流(liu)(liu)到放熱水的(de)(de)管道里(li)而不能(neng)流(liu)(liu)到冷水管里(li)。通(tong)常(chang)來說電(dian)(dian)(dian)磁(ci)閥和(he)太(tai)陽(yang)(yang)能(neng)儀表是(shi)(shi)(shi)(shi)搭(da)配使(shi)用(yong)的(de)(de)，應該是(shi)(shi)(shi)(shi)全自動控(kong)制的(de)(de)，所以在試用(yong)太(tai)陽(yang)(yang)能(neng)熱水器的(de)(de)時(shi)候(hou)是(shi)(shi)(shi)(shi)不需要去(qu)單獨(du)控(kong)制電(dian)(dian)(dian)磁(ci)閥的(de)(de)。

太(tai)陽能(neng)(neng)電(dian)(dian)磁(ci)(ci)閥分為有壓(ya)(ya)(ya)和無(wu)壓(ya)(ya)(ya)兩種，如果(guo)冷水水壓(ya)(ya)(ya)比(bi)較小的話最好是(shi)選(xuan)擇(ze)無(wu)壓(ya)(ya)(ya)閥，否(fou)則電(dian)(dian)磁(ci)(ci)閥可能(neng)(neng)打不(bu)開，就不(bu)能(neng)(neng)正常上(shang)水；如果(guo)水水壓(ya)(ya)(ya)較大的話，就選(xuan)擇(ze)有壓(ya)(ya)(ya)閥，否(fou)則電(dian)(dian)磁(ci)(ci)閥可能(neng)(neng)不(bu)能(neng)(neng)止回，也就是(shi)說熱水器里的水可能(neng)(neng)會倒流到冷水管當中(zhong)或者電(dian)(dian)磁(ci)(ci)閥無(wu)法關閉(bi)，造成熱水器溫度升不(bu)上(shang)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(yuan)因(yin)分析：出現這種情況的可能性比較多(duo)，有可能是電(dian)(dian)(dian)源處(chu)的接線接觸(chu)不(bu)良(liang)所導(dao)致，可能是在電(dian)(dian)(dian)源電(dian)(dian)(dian)壓的變動幅度(du)過大導(dao)致電(dian)(dian)(dian)線燒壞或者是短路。解決(jue)方法：注(zhu)意檢查(cha)排除，將電(dian)(dian)(dian)源線接好，并且調整電(dian)(dian)(dian)壓，使其保持(chi)在一個穩(wen)定的范圍內。可以更換線圈。

2、故障表現：在開閥的時候，流體不能夠通過

原(yuan)因分(fen)析及對應(ying)方(fang)法：出(chu)現(xian)這種故障的(de)情況也是(shi)非常的(de)多，一是(shi)流體(ti)的(de)壓(ya)(ya)力或(huo)者(zhe)是(shi)其(qi)工(gong)作(zuo)的(de)壓(ya)(ya)力差不符合正常的(de)運作(zuo)范(fan)圍，這時就需要調(diao)整(zheng)壓(ya)(ya)力或(huo)者(zhe)工(gong)作(zuo)壓(ya)(ya)差;二是(shi)在閥芯或(huo)者(zhe)是(shi)在動鐵芯的(de)地(di)方(fang)混入(ru)了大量的(de)污垢雜質，這時需要將其(qi)內(nei)部清(qing)(qing)理(li)干凈(jing)(jing)即可;三是(shi)閥前過濾器堵塞(sai)了，這時將過濾器清(qing)(qing)洗干凈(jing)(jing)即可。

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

原因分析及對應方法：一種是管(guan)道的連接(jie)處沒有安裝牢固，出(chu)(chu)現了松動(dong)情(qing)況(kuang)(kuang)，這(zhe)時將螺栓擰緊(jin)即可。一種是管(guan)道的連接(jie)外(wai)密封件出(chu)(chu)現了損(sun)壞(huai)，這(zhe)種情(qing)況(kuang)(kuang)只能重(zhong)新更換一個密封件。

4、故障表現：在通電運轉的時候，噪音特別的大

原因(yin)分析(xi)及對應方法：一是緊固件的(de)(de)(de)地方出現(xian)了松動(dong)，擰緊即可。二(er)是電壓的(de)(de)(de)波(bo)動(dong)幅度(du)太(tai)大，超過了允許的(de)(de)(de)范圍，這時調整(zheng)電壓到正常運(yun)轉的(de)(de)(de)范圍即可。
