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)極一長(chang)（下限(xian)(xian)）一短（上(shang)限(xian)(xian)），當水(shui)(shui)位(wei)在(zai)下限(xian)(xian)時，也(ye)就是水(shui)(shui)沒有漫(man)過(guo)長(chang)電(dian)(dian)(dian)(dian)極，繼電(dian)(dian)(dian)(dian)器(qi)(qi)不得(de)電(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)磁閥(fa)打開(kai)(kai)(kai)上(shang)水(shui)(shui)。當水(shui)(shui)位(wei)上(shang)升到上(shang)限(xian)(xian)兩根電(dian)(dian)(dian)(dian)極通(tong)過(guo)水(shui)(shui)導通(tong)，繼電(dian)(dian)(dian)(dian)器(qi)(qi)得(de)電(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)磁閥(fa)關(guan)閉，停(ting)止上(shang)水(shui)(shui)。還(huan)有你可以用浮(fu)子開(kai)(kai)(kai)關(guan)控制自(zi)動上(shang)水(shui)(shui)，這(zhe)樣電(dian)(dian)(dian)(dian)路簡便，只要將電(dian)(dian)(dian)(dian)源串(chuan)在(zai)浮(fu)子開(kai)(kai)(kai)關(guan)上(shang)，通(tong)過(guo)開(kai)(kai)(kai)關(guan)控制繼電(dian)(dian)(dian)(dian)器(qi)(qi)，再(zai)由繼電(dian)(dian)(dian)(dian)器(qi)(qi)控制電(dian)(dian)(dian)(dian)磁閥(fa)。原(yuan)理水(shui)(shui)面達到上(shang)限(xian)(xian)浮(fu)子開(kai)(kai)(kai)關(guan)斷(duan)(duan)開(kai)(kai)(kai)，繼電(dian)(dian)(dian)(dian)器(qi)(qi)失電(dian)(dian)(dian)(dian)斷(duan)(duan)開(kai)(kai)(kai)電(dian)(dian)(dian)(dian)磁閥(fa)，下限(xian)(xian)浮(fu)子開(kai)(kai)(kai)關(guan)接(jie)通(tong)繼電(dian)(dian)(dian)(dian)器(qi)(qi)得(de)電(dian)(dian)(dian)(dian)接(jie)通(tong)電(dian)(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(xi)管路(lu)，將(jiang)雜質沖洗(xi)干凈。

2、若是水塔(ta)供(gong)水，請選擇與水壓相適配電磁閥。以免(mian)電磁閥不能上水或流量過小。

3、檢(jian)查電磁閥(fa)(fa)標識電壓(ya)是否(fou)與控制電源輸出(chu)電壓(ya)一致(zhi)，檢(jian)查過濾網是否(fou)完整、閥(fa)(fa)體各(ge)部位(wei)是否(fou)無破損。

4、將測(ce)控儀配套(tao)的電磁閥安裝在冷(leng)熱(re)水(shui)管相通的管路上(shang)。電磁閥有濾網(wang)端(duan)為進水(shui)口，閥體上(shang)箭頭與上(shang)水(shui)水(shui)流方向相同(tong)，不可接反(fan)，電磁閥閥體朝上(shang)并(bing)處于水(shui)平位置安裝。

5、安裝(zhuang)好后，通電(dian)檢測。

三、太陽能熱水器電磁閥安裝注意事項

電磁閥的(de)作用是使(shi)管(guan)道中(zhong)的(de)止回(hui)或定向流動(dong)，電(dian)(dian)磁(ci)閥(fa)在(zai)給太陽(yang)能(neng)熱(re)水(shui)(shui)器(qi)上水(shui)(shui)的(de)時(shi)(shi)候它就(jiu)(jiu)打開(kai)，讓冷(leng)水(shui)(shui)進入水(shui)(shui)箱當中(zhong)，當停止上水(shui)(shui)的(de)時(shi)(shi)候電(dian)(dian)磁(ci)閥(fa)就(jiu)(jiu)關閉(bi)了，那(nei)(nei)么太陽(yang)能(neng)水(shui)(shui)箱中(zhong)水(shui)(shui)就(jiu)(jiu)不(bu)能(neng)通過電(dian)(dian)磁(ci)閥(fa)倒流回(hui)冷(leng)水(shui)(shui)管(guan)里(li)。如(ru)果當使(shi)用熱(re)水(shui)(shui)器(qi)里(li)的(de)水(shui)(shui)的(de)時(shi)(shi)候，電(dian)(dian)磁(ci)閥(fa)依(yi)然是關閉(bi)的(de)，那(nei)(nei)么水(shui)(shui)就(jiu)(jiu)只能(neng)流到放熱(re)水(shui)(shui)的(de)管(guan)道里(li)而(er)不(bu)能(neng)流到冷(leng)水(shui)(shui)管(guan)里(li)。通常來說(shuo)電(dian)(dian)磁(ci)閥(fa)和(he)太陽(yang)能(neng)儀表是搭配使(shi)用的(de)，應(ying)該是全(quan)自動(dong)控制的(de)，所(suo)以在(zai)試用太陽(yang)能(neng)熱(re)水(shui)(shui)器(qi)的(de)時(shi)(shi)候是不(bu)需要去單獨控制電(dian)(dian)磁(ci)閥(fa)的(de)。

太陽能電(dian)(dian)磁(ci)閥分為有壓(ya)和無(wu)(wu)壓(ya)兩(liang)種，如(ru)果冷水(shui)(shui)(shui)(shui)(shui)水(shui)(shui)(shui)(shui)(shui)壓(ya)比(bi)較小的(de)話(hua)最好是選擇(ze)無(wu)(wu)壓(ya)閥，否(fou)則電(dian)(dian)磁(ci)閥可(ke)能打(da)不(bu)(bu)開，就不(bu)(bu)能正常上(shang)水(shui)(shui)(shui)(shui)(shui)；如(ru)果水(shui)(shui)(shui)(shui)(shui)水(shui)(shui)(shui)(shui)(shui)壓(ya)較大的(de)話(hua)，就選擇(ze)有壓(ya)閥，否(fou)則電(dian)(dian)磁(ci)閥可(ke)能不(bu)(bu)能止回，也就是說熱(re)水(shui)(shui)(shui)(shui)(shui)器里的(de)水(shui)(shui)(shui)(shui)(shui)可(ke)能會倒流到冷水(shui)(shui)(shui)(shui)(shui)管(guan)當中或者電(dian)(dian)磁(ci)閥無(wu)(wu)法關閉，造成熱(re)水(shui)(shui)(shui)(shui)(shui)器溫度升不(bu)(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

原因分析(xi)：出現這種情(qing)況(kuang)的(de)可能性比較多，有可能是電(dian)源(yuan)(yuan)處的(de)接線接觸不(bu)良所導(dao)致(zhi)，可能是在電(dian)源(yuan)(yuan)電(dian)壓的(de)變(bian)動幅(fu)度(du)過大導(dao)致(zhi)電(dian)線燒壞或(huo)者是短路(lu)。解(jie)決方(fang)法：注意(yi)檢查排除，將電(dian)源(yuan)(yuan)線接好，并且調(diao)整電(dian)壓，使(shi)其(qi)保持在一個穩定的(de)范圍內(nei)。可以更換線圈。

2、故障表現：在開閥的時候，流體不能夠通過

原因分(fen)析及對應方法：出現這(zhe)種(zhong)故障的情況(kuang)也(ye)是非常的多(duo)，一是流(liu)體的壓(ya)力或(huo)者是其工(gong)作的壓(ya)力差不符合正常的運作范(fan)圍，這(zhe)時就需要(yao)調(diao)整(zheng)壓(ya)力或(huo)者工(gong)作壓(ya)差;二是在閥(fa)芯或(huo)者是在動鐵芯的地方混入了大量(liang)的污(wu)垢雜(za)質(zhi)，這(zhe)時需要(yao)將其內部(bu)清理干凈(jing)(jing)即可;三是閥(fa)前過濾器堵塞(sai)了，這(zhe)時將過濾器清洗干凈(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(yin)分析及對(dui)應方法：一種(zhong)是管(guan)道的連接處沒(mei)有(you)安(an)裝牢固，出(chu)(chu)現(xian)了松(song)動(dong)情(qing)況，這(zhe)時將螺栓(shuan)擰緊(jin)即可。一種(zhong)是管(guan)道的連接外(wai)密(mi)封件(jian)出(chu)(chu)現(xian)了損壞，這(zhe)種(zhong)情(qing)況只能重新更換(huan)一個(ge)密(mi)封件(jian)。

4、故障表現：在通電運轉的時候，噪音特別的大

原因分析及對應方法：一(yi)是(shi)緊(jin)(jin)固件的(de)地方出現了松(song)動(dong)，擰緊(jin)(jin)即(ji)可。二是(shi)電壓(ya)(ya)的(de)波動(dong)幅(fu)度太大(da)，超過(guo)了允許的(de)范圍，這時調整電壓(ya)(ya)到正(zheng)常(chang)運轉(zhuan)的(de)范圍即(ji)可。
