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(yi)(yi)長(chang)(chang)（下限(xian)(xian)）一(yi)(yi)短(duan)（上(shang)限(xian)(xian)），當(dang)水(shui)(shui)位在(zai)下限(xian)(xian)時，也就(jiu)是水(shui)(shui)沒有(you)漫過長(chang)(chang)電(dian)(dian)(dian)(dian)(dian)極(ji)，繼(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)不得電(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)磁(ci)閥打(da)開(kai)(kai)上(shang)水(shui)(shui)。當(dang)水(shui)(shui)位上(shang)升(sheng)到(dao)上(shang)限(xian)(xian)兩根電(dian)(dian)(dian)(dian)(dian)極(ji)通(tong)(tong)(tong)過水(shui)(shui)導(dao)通(tong)(tong)(tong)，繼(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)得電(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)磁(ci)閥關閉，停(ting)止上(shang)水(shui)(shui)。還有(you)你可以用(yong)浮(fu)子(zi)開(kai)(kai)關控(kong)制(zhi)自(zi)動(dong)上(shang)水(shui)(shui)，這樣電(dian)(dian)(dian)(dian)(dian)路簡便，只(zhi)要將電(dian)(dian)(dian)(dian)(dian)源串在(zai)浮(fu)子(zi)開(kai)(kai)關上(shang)，通(tong)(tong)(tong)過開(kai)(kai)關控(kong)制(zhi)繼(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)，再由繼(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)控(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)磁(ci)閥。原理水(shui)(shui)面達到(dao)上(shang)限(xian)(xian)浮(fu)子(zi)開(kai)(kai)關斷(duan)開(kai)(kai)，繼(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)失電(dian)(dian)(dian)(dian)(dian)斷(duan)開(kai)(kai)電(dian)(dian)(dian)(dian)(dian)磁(ci)閥，下限(xian)(xian)浮(fu)子(zi)開(kai)(kai)關接(jie)(jie)通(tong)(tong)(tong)繼(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)得電(dian)(dian)(dian)(dian)(dian)接(jie)(jie)通(tong)(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(qian)先沖洗管路(lu)，將雜質沖洗干(gan)凈。

2、若(ruo)是水(shui)(shui)(shui)塔供水(shui)(shui)(shui)，請選擇與水(shui)(shui)(shui)壓相適配電磁(ci)閥。以免電磁(ci)閥不(bu)能(neng)上水(shui)(shui)(shui)或流量過小。

3、檢(jian)查(cha)電(dian)磁閥(fa)(fa)標識電(dian)壓是(shi)否(fou)與(yu)控制(zhi)電(dian)源輸(shu)出電(dian)壓一致，檢(jian)查(cha)過濾網是(shi)否(fou)完整(zheng)、閥(fa)(fa)體各部位(wei)是(shi)否(fou)無破損。

4、將測控儀配套(tao)的電磁閥(fa)安裝在冷熱水(shui)管相通的管路上(shang)。電磁閥(fa)有(you)濾網端為進(jin)水(shui)口，閥(fa)體(ti)上(shang)箭頭與(yu)上(shang)水(shui)水(shui)流(liu)方(fang)向相同(tong)，不可(ke)接反(fan)，電磁閥(fa)閥(fa)體(ti)朝上(shang)并處(chu)于水(shui)平位置安裝。

5、安裝(zhuang)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)作用是(shi)(shi)使管(guan)道中的(de)止回或定(ding)向流動(dong)，電磁(ci)閥(fa)(fa)(fa)在(zai)給太陽能(neng)熱水(shui)(shui)(shui)器上水(shui)(shui)(shui)的(de)時(shi)候它就(jiu)打(da)開，讓冷(leng)水(shui)(shui)(shui)進(jin)入水(shui)(shui)(shui)箱當(dang)(dang)中，當(dang)(dang)停止上水(shui)(shui)(shui)的(de)時(shi)候電磁(ci)閥(fa)(fa)(fa)就(jiu)關閉了，那(nei)么(me)太陽能(neng)水(shui)(shui)(shui)箱中水(shui)(shui)(shui)就(jiu)不(bu)能(neng)通(tong)過電磁(ci)閥(fa)(fa)(fa)倒流回冷(leng)水(shui)(shui)(shui)管(guan)里。如果當(dang)(dang)使用熱水(shui)(shui)(shui)器里的(de)水(shui)(shui)(shui)的(de)時(shi)候，電磁(ci)閥(fa)(fa)(fa)依然是(shi)(shi)關閉的(de)，那(nei)么(me)水(shui)(shui)(shui)就(jiu)只能(neng)流到放熱水(shui)(shui)(shui)的(de)管(guan)道里而不(bu)能(neng)流到冷(leng)水(shui)(shui)(shui)管(guan)里。通(tong)常(chang)來說電磁(ci)閥(fa)(fa)(fa)和太陽能(neng)儀(yi)表是(shi)(shi)搭配(pei)使用的(de)，應該是(shi)(shi)全自動(dong)控制的(de)，所以在(zai)試用太陽能(neng)熱水(shui)(shui)(shui)器的(de)時(shi)候是(shi)(shi)不(bu)需要去(qu)單(dan)獨控制電磁(ci)閥(fa)(fa)(fa)的(de)。

太(tai)陽能(neng)(neng)電磁閥(fa)分為有(you)壓(ya)(ya)和(he)無(wu)壓(ya)(ya)兩種，如果冷水(shui)(shui)水(shui)(shui)壓(ya)(ya)比(bi)較小的(de)話(hua)最好是(shi)選擇無(wu)壓(ya)(ya)閥(fa)，否則(ze)電磁閥(fa)可(ke)能(neng)(neng)打(da)不(bu)開，就不(bu)能(neng)(neng)正常上(shang)水(shui)(shui)；如果水(shui)(shui)水(shui)(shui)壓(ya)(ya)較大的(de)話(hua)，就選擇有(you)壓(ya)(ya)閥(fa)，否則(ze)電磁閥(fa)可(ke)能(neng)(neng)不(bu)能(neng)(neng)止回(hui)，也就是(shi)說熱水(shui)(shui)器里的(de)水(shui)(shui)可(ke)能(neng)(neng)會倒流到冷水(shui)(shui)管當中或(huo)者(zhe)電磁閥(fa)無(wu)法關閉，造成熱水(shui)(shui)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

原因分(fen)析：出現這種(zhong)情況的可(ke)能性比較多，有可(ke)能是(shi)電(dian)(dian)(dian)(dian)源(yuan)(yuan)處的接(jie)(jie)線接(jie)(jie)觸(chu)不良所導致，可(ke)能是(shi)在(zai)電(dian)(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)(dian)壓(ya)的變動幅度過大導致電(dian)(dian)(dian)(dian)線燒壞或者是(shi)短路。解(jie)決方法：注意(yi)檢查排除，將電(dian)(dian)(dian)(dian)源(yuan)(yuan)線接(jie)(jie)好，并(bing)且調整電(dian)(dian)(dian)(dian)壓(ya)，使(shi)其保持在(zai)一個(ge)穩(wen)定(ding)的范(fan)圍內。可(ke)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(xi)及對應方(fang)法：出現這(zhe)種故障的(de)(de)(de)情(qing)況(kuang)也是(shi)(shi)非常的(de)(de)(de)多，一是(shi)(shi)流體的(de)(de)(de)壓(ya)力(li)或(huo)(huo)者(zhe)是(shi)(shi)其工作(zuo)的(de)(de)(de)壓(ya)力(li)差(cha)不(bu)符(fu)合正常的(de)(de)(de)運作(zuo)范(fan)圍(wei)，這(zhe)時就需(xu)要(yao)調(diao)整壓(ya)力(li)或(huo)(huo)者(zhe)工作(zuo)壓(ya)差(cha);二是(shi)(shi)在閥芯(xin)或(huo)(huo)者(zhe)是(shi)(shi)在動鐵芯(xin)的(de)(de)(de)地方(fang)混入了(le)大量的(de)(de)(de)污垢(gou)雜(za)質，這(zhe)時需(xu)要(yao)將其內部清(qing)理干凈即可(ke);三是(shi)(shi)閥前過濾器堵塞了(le)，這(zhe)時將過濾器清(qing)洗干凈即可(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

原因分析及對應(ying)方法：一種(zhong)(zhong)是管道的(de)連接處沒(mei)有安裝(zhuang)牢固，出現(xian)了松動情況，這時將(jiang)螺栓(shuan)擰緊(jin)即可。一種(zhong)(zhong)是管道的(de)連接外密(mi)封(feng)件出現(xian)了損壞，這種(zhong)(zhong)情況只能重新更(geng)換(huan)一個密(mi)封(feng)件。

4、故障表現：在通電運轉的時候，噪音特別的大

原(yuan)因分(fen)析及對(dui)應方法：一是緊固件(jian)的(de)地方出現了松(song)動(dong)，擰(ning)緊即可。二是電壓(ya)(ya)的(de)波動(dong)幅度(du)太大(da)，超(chao)過了允(yun)許的(de)范圍(wei)(wei)，這(zhe)時(shi)調整電壓(ya)(ya)到正常(chang)運轉(zhuan)的(de)范圍(wei)(wei)即可。
