熱水器已成為生活中重要的一部分，給人們的生活帶來(lái)極大的方便。但由于元器件自然老化、操作者的熟練程度、工作環(huán)境和工作強(qiáng)度等諸多因素常引發(fā)各類(lèi)故障。接下來(lái)就為大家介紹如何維修熱水器的問(wèn)題。

電熱水器

工作原理

電熱水器具有結(jié)構(gòu)簡(jiǎn)單、價(jià)格低、熱效率高、無(wú)污染、使用方便等優(yōu)點(diǎn)，使用壽命一般為15年左右，主要有貯水式和速熱式兩種。由于速熱式電熱水器功率高達(dá)3kW以上，且易漏電，很少有人問(wèn)津；貯水式一般功率在1~2kW之間，安全方便，受到消費(fèi)者喜愛(ài)。

一、貯水式電熱水器

貯水式電熱水器一般由箱體系統(tǒng)、制熱系統(tǒng)、控制系統(tǒng)和進(jìn)出水系統(tǒng)四大部分組成。下面為部分國(guó)產(chǎn)名牌電熱水器的結(jié)構(gòu)示意圖。

1、箱體系統(tǒng)

箱體系統(tǒng)由外殼、內(nèi)膽、保溫層等構(gòu)成，起到貯水保溫的作用。

（1）外殼

外殼是電熱水器的基本骨架，大部分部件都安裝或固定在上面，所用材料有塑料、彩板、冷軋板、噴粉等幾種。

（2）內(nèi)膽

內(nèi)膽既是盛水的容器，又是對(duì)外加熱的場(chǎng)所，其壽命決定于內(nèi)膽的材料和制造工藝。常見(jiàn)內(nèi)膽材料有鍍鋅鐵板、不銹鋼板和鋼板內(nèi)涂搪瓷三種。

（3）陽(yáng)級(jí)棒

貯水式電熱水器中的陽(yáng)極棒是一根金屬鎂棒，主要用來(lái)保護(hù)金屬水箱不被腐蝕和阻止水垢的形成。

（4）保溫層

外殼與內(nèi)膽之間的保溫層，起減少熱損失的作用，一般采用聚氨酯發(fā)泡、玻璃棉、石棉、纖維、氈和軟木等。為增強(qiáng)保溫效果，現(xiàn)多采用高密度聚氨酯發(fā)泡材料充填的新工藝，充填扎實(shí)，密封保溫性好，即使12h不通電，水溫也僅下降2℃左右。

（5）爐膛

爐膛用于安裝加熱體和限溫器，是由爐膛底盤(pán)、爐膛管、爐膛帽、溫控管、螺孔柱焊接而成。螺孔柱經(jīng)鉆孔攻螺紋，用于安裝鎂棒。

2、制熱系統(tǒng)

電熱水器采用的電熱元件多采用管狀結(jié)構(gòu)，為提高熱效率，直接放在水中加熱，形狀可根據(jù)內(nèi)膽結(jié)構(gòu)彎成U形或其他形狀，金屬護(hù)套管常見(jiàn)為不銹鋼管或銅管。電加熱管在通電后，其內(nèi)部高電阻電熱合金絲發(fā)熱，通過(guò)金屬管內(nèi)的絕緣填充料導(dǎo)熱至金屬套管，起加熱作用。

電加熱管使用時(shí)間一長(zhǎng)，在電加熱管表面容易結(jié)污垢，不僅影響發(fā)熱效果，而且會(huì)產(chǎn)生漏電現(xiàn)象。為此海爾、小鴨、東寶等廠家，將熱水器部分產(chǎn)品的電熱元件改為高壓耐熱的陶瓷發(fā)熱器，如圖所示。間接加熱內(nèi)膽中的水（通電后，首先預(yù)熱周?chē)目諝猓缓笸ㄟ^(guò)鋼板對(duì)水加熱），使水電分離，不僅無(wú)漏電之憂，且可超快速加熱。

3、控制系統(tǒng)

電熱水器的控制系統(tǒng)主要包括溫控器和漏電保護(hù)器。

（1）溫控器

電熱水器中使用的溫控器主要有雙金屬片溫控器、蒸氣壓力式溫控器和電子溫控器。

（2）漏電保護(hù)器

在電熱水器的漏電保護(hù)器中、將15mA確定為危險(xiǎn)電流，超過(guò)這一數(shù)值時(shí)漏電保護(hù)器動(dòng)作，正常的動(dòng)作范圍為15~30mA。

海爾電熱水器選用的是進(jìn)口漏電保護(hù)器，動(dòng)作值為15mA，動(dòng)作時(shí)間為0.1s。小鴨等品牌電熱水器電源線帶有先進(jìn)的電子控制漏電保護(hù)插頭，其技術(shù)參數(shù)為：額定電壓220V（5OHz），額定電流10A，漏電動(dòng)作范圍5~10mA，漏電動(dòng)作時(shí)間≤50ms，最大分?jǐn)嗄芰?00A，最大負(fù)載功率2200W。

4、進(jìn)、出水系統(tǒng)

進(jìn)、出水系統(tǒng)由進(jìn)、出水管，混合閥、安全閥和淋浴噴頭等組成。

（1）混合閥

混合閥的結(jié)構(gòu)如圖所示。由圖可知，熱水器內(nèi)膽出水管、混合閥、噴頭和大氣相通，不受混合閥冷、熱閥門(mén)控制膽內(nèi)壓力，故稱(chēng)為出口敞開(kāi)式。

單獨(dú)打開(kāi)右側(cè)紅點(diǎn)熱水旋閥，自來(lái)水經(jīng)出水管、混合閥、噴頭流出，出熱水，出水壓力由熱水閥控制；單獨(dú)打開(kāi)左側(cè)藍(lán)點(diǎn)冷水旋閥，自來(lái)水直接經(jīng)混合閥由噴頭流出冷水，出水壓力由冷水閥控制。當(dāng)同時(shí)打開(kāi)冷熱水閥門(mén)時(shí)，冷水和熱水在混合閥出水口混合，適當(dāng)調(diào)節(jié)冷熱水閥門(mén)大小，可得到所需水溫。

（2）安全閥

在自來(lái)水壓力突然增高或加熱水溫過(guò)熱，造成內(nèi)膽壓力超過(guò)規(guī)定耐壓值時(shí)，安全閥會(huì)自動(dòng)排壓，以保護(hù)內(nèi)膽。在加熱過(guò)程中，安全閥會(huì)有緩慢的滴水現(xiàn)象，不是故障，是一種正常現(xiàn)象。

5、工作原理

貯水式電熱水器的加熱分單加熱器加熱和雙加熱器加熱兩種。前者，--般用在容積不太大的熱水器中；后者、往往用于容積較大的熱水器中。

二、速熱式電熱水器

快速熱水器一般在接通電源、開(kāi)啟水閥后，僅需十幾秒就會(huì)有充足的熱水源源流出，因此也稱(chēng)流動(dòng)式或即熱式電熱水器。

1、基本結(jié)構(gòu)

快速熱水器主要由外殼、內(nèi)腔、電熱元件、壓力開(kāi)關(guān)和溫度控制等部分組成。

2、工作原理

（1）腔體式

打開(kāi)進(jìn)水閥門(mén)，水流入腔體。當(dāng)水充滿腔體后，在水壓和重力作用下，使橡皮膜下凹，從而帶動(dòng)通過(guò)膜片中心的通水管子上端，使觸點(diǎn)閉合接通電源，這樣電阻絲通電發(fā)熱，被加熱的水沿通水管上開(kāi)有的小孔流入管內(nèi)，再經(jīng)過(guò)蓮蓬頭噴射出來(lái)，供人們使用。當(dāng)停止進(jìn)水時(shí)，靠橡皮膜彈力恢復(fù)使觸頭斷開(kāi)，從而切斷電源。

（2）水槽式

在未接通水源時(shí)，壓力開(kāi)關(guān)處于常態(tài)（觸點(diǎn)斷開(kāi)），微動(dòng)開(kāi)關(guān)s不動(dòng)作，從而繼電器線圈不通電，這時(shí)整機(jī)不工作。接通水源后，因水壓升高，這時(shí)壓力開(kāi)關(guān)觸點(diǎn)動(dòng)作，繼電器KA吸合，主電路觸點(diǎn)閉合，指示燈HL點(diǎn)亮，這時(shí)只要將轉(zhuǎn)換開(kāi)關(guān)（功率調(diào)節(jié)器）根據(jù)需要調(diào)節(jié)在適當(dāng)位置，電熱元件即可工作，就會(huì)有熱水從蓮蓬頭中源源不斷流出。

常見(jiàn)故障分析

一、電熱水器檢修工藝

下面以海爾電熱水器為例，對(duì)電熱水器的檢修工藝過(guò)程介紹如下：

1、電源檢查

用萬(wàn)用表交流電壓檔（~500V檔）測(cè)量插座零線和火線，零線和地線是否接通，若不通為正常；反之，則電源不能使用，應(yīng)修復(fù)。

（萬(wàn)用表使用方法圖解）

2、故障檢修程序

接通電源，可能出現(xiàn)兩種情況：指示燈亮或指示燈不亮。

（1）指示燈亮：待半小時(shí)左右，水溫升高10℃左右，說(shuō)明熱水器正常；若水溫不升高，由燈亮可知，漏電保護(hù)器、超溫管均正常，故障在加熱器。斷電后，檢測(cè)加熱元件，若電阻為無(wú)窮大，應(yīng)更換。

（2）指示燈不亮：若燈壞應(yīng)更換；燈好時(shí)，應(yīng)檢查溫控器、超溫管、加熱器和漏電保護(hù)器以確定故障所在。

①對(duì)可調(diào)溫型溫控器，用萬(wàn)用表R×1檔測(cè)量，在關(guān)斷位置電阻為無(wú)窮大；在不同溫度控制點(diǎn)應(yīng)有不同電阻值與之對(duì)應(yīng)；溫控器在未動(dòng)作時(shí)，觸點(diǎn)為閉合狀態(tài)，電阻近似為0，否則說(shuō)明溫控器損壞，應(yīng)更換。

（萬(wàn)用表測(cè)量溫控器圖解）

②超溫管在正常狀態(tài)下，電阻為0，否則已損壞，應(yīng)更換。

③用萬(wàn)用表檢測(cè)加熱器，電阻約24~48Ω，若為無(wú)窮大時(shí)，應(yīng)更換加熱元件。

④檢查漏電保護(hù)器，應(yīng)將漏電保護(hù)器打到合閘位置，燈亮，水溫升高為正常；有時(shí)漏電保護(hù)器誤動(dòng)作，應(yīng)注意觀察，找出誤動(dòng)作原因。

（漏電保護(hù)器“合閘”狀態(tài)）

若漏電保護(hù)器合不上閘，應(yīng)用萬(wàn)用表R×100檔依次檢測(cè)超溫管、溫控器和加熱器的對(duì)地電阻，表針指向∞位置為正常，表針指向0為漏電，找出漏電元件進(jìn)行更換，若無(wú)漏電元件，說(shuō)明漏電保護(hù)器已損壞，更換新的。

（漏電保護(hù)器“跳閘”狀態(tài)）

3、安全性能測(cè)試

（1）漏電測(cè)試：重新合閘，按“試驗(yàn)”按鈕應(yīng)跳閘，漏電保護(hù)器為正常，再“合閘”燈亮。若熱水器無(wú)漏電保護(hù)器，用萬(wàn)用表電阻檔測(cè)量插頭的火線與地線、零線和地線，若指示為無(wú)窮大，說(shuō)明無(wú)漏電現(xiàn)象。

（2）泄漏電流測(cè)試：泄漏電流不應(yīng)超過(guò)規(guī)定的數(shù)值，海爾小海象為0.5mA/kW，大海象、金海象為0.3mA/kW，

（3）絕緣電阻用兆歐表測(cè)量應(yīng)大于50MΩ。

（4）電源的接地端與電熱水器易觸及金屬部件之間的接地電阻應(yīng)小于0.1Ω。

安全性能測(cè)試合格后，才能按工藝要求將電熱水器重新安裝好，投入使用。

二、電熱水器常見(jiàn)故障分析

1、出水不熱

（1）冷熱水調(diào)節(jié)不當(dāng)：這是由于熱水閥開(kāi)得太小，冷水閥開(kāi)得太大造成的。應(yīng)適當(dāng)調(diào)節(jié)冷熱水閥的開(kāi)度，使出水溫度適合使用。

（2）電源未接通：調(diào)整電源插頭或開(kāi)關(guān)，使其接觸良好。若采用的是漏電保護(hù)插頭，應(yīng)將其“復(fù)位按鈕”按下，排除以上故障若仍不能接通電源，應(yīng)拆開(kāi)電熱水器仔細(xì)檢查回路是否有導(dǎo)線脫落、斷開(kāi)等情況，若有，應(yīng)及時(shí)排除。

（3）電加熱器損壞：用萬(wàn)用表電阻檔測(cè)量電熱元件電阻值，正常情況下，1kW電熱水器，電阻為49Ω左右；3kW，16Ω左右。功率不同的電熱水器，其電熱元件的阻值不同。若電阻為無(wú)窮大，說(shuō)明電熱元件損壞，應(yīng)予更換。

（4）溫控器損壞：當(dāng)溫控器觸頭接觸不良或感溫體內(nèi)感溫劑泄漏時(shí)，可引起溫控器不能正常工作。對(duì)于前者可拆開(kāi)壓力式溫控器進(jìn)行修復(fù)；對(duì)于后者只好更換新的壓力式溫控器。

2、出水溫度太高

（1）冷熱水調(diào)節(jié)不當(dāng)：適當(dāng)調(diào)節(jié)冷熱水閥的開(kāi)度。

（2）溫控器旋鈕調(diào)節(jié)不當(dāng)或觸點(diǎn)粘連：將溫控器旋鈕調(diào)至溫度較低處；對(duì)觸點(diǎn)粘連的，可將溫控器拆開(kāi)，將粘連觸點(diǎn)分開(kāi)，并對(duì)觸點(diǎn)進(jìn)行研修、調(diào)整，經(jīng)調(diào)整后，一般即可使用，必要時(shí)可進(jìn)行更換。

（3）限溫器失靈：檢修限溫器。

3、漏水

（1）管道連接處漏水：對(duì)接口密封不好造成的漏水，應(yīng)重新安裝接口；若屬自來(lái)水壓太高，應(yīng)在自來(lái)水道上設(shè)置減壓閥。

（2）安全閥接口漏水：是由于安全閥松扣或密封不好造成的，應(yīng)重新擰緊和密封。

4、出水帶電

（1）出水口接地失效：重新接好接地線，保證接地電阻小于0.1Ω。

（2）水中分布電流大：用細(xì)鋼絲編織成網(wǎng)，包在出水口上，并與接地線良好接觸。

（3）電熱元件絕緣損壞或失效：更換電熱元件，更換時(shí)要保持電氣接觸良好，有關(guān)密封部分不漏水。

（4）內(nèi)部導(dǎo)線絕緣層損壞，搭接在外殼或內(nèi)膽上：拆開(kāi)電熱水器，檢查出導(dǎo)線絕緣層損壞的部分，進(jìn)行更換。

5、進(jìn)水困難

（1）臟堵：主要是由于自來(lái)水水質(zhì)不好，雜質(zhì)超量，堵住進(jìn)水口的逆止閥。設(shè)有進(jìn)水濾網(wǎng)的熱水器大都是濾網(wǎng)孔被堵。在確定水壓正常后，關(guān)閉自來(lái)水供水總閥，清理管路，沖出勝物或清洗濾網(wǎng)。

（2）汽堵：常見(jiàn)于密閉水箱貯水式電熱水器中。其特征是：熱水閥打開(kāi)后，噴出大量水蒸氣，此時(shí)應(yīng)將調(diào)溫器調(diào)到最小位置或切斷電源，先將蒸汽從熱水閥排出，然后打開(kāi)冷水進(jìn)水閥，使熱水器排水，降低水溫，再檢修溫控器；若熱水閥打開(kāi)后，熱汽斷續(xù)流出，量很小，一般是臟堵造成的。此時(shí)應(yīng)開(kāi)大熱水閥和冷水進(jìn)水閥，以降低水溫，待水溫降低后，檢查熱水閥是否臟堵，洗凈后冷水便會(huì)從熱水閥流出。

（3）供水壓力不正常：當(dāng)供水管路因水壓下降，供水壓力低于貯水壓力，逆止閥不能被頂開(kāi)，會(huì)造成進(jìn)水困難。這種故障，待水壓正常后，故障即自行消失。

保養(yǎng)

使用一段時(shí)間后，應(yīng)取下噴頭，按安裝方法進(jìn)行沖洗。長(zhǎng)期使用后，若升溫慢，應(yīng)檢查電熱元件是否結(jié)垢，若結(jié)垢，可用去垢劑清除水垢。

若漏水，應(yīng)更換相應(yīng)的橡膠密封圈。

若加熱時(shí)蒸汽冒出，則表明恒溫器失效。或感溫頭脫出，應(yīng)關(guān)閉電路，經(jīng)檢查修復(fù)后再用。

加熱時(shí)因水的膨脹,噴頭有時(shí)會(huì)有少量熱水溢出，這屬正?，F(xiàn)象,不必過(guò)分用力擰緊熱水閥,以免加速損壞密封圈。

自來(lái)水閥可使用不帶手輪的閥門(mén)或者安裝好后取下手輪，以防誤關(guān)此閥,導(dǎo)致水箱缺水而燒毀電熱絲。

燃?xì)鉄崴?

結(jié)構(gòu)

目前，家用快速燃?xì)鉄崴鞒Ｒ?jiàn)為壁掛式，適合淋浴使用，主要由水路系統(tǒng)、燃?xì)庀到y(tǒng)、熱交換系統(tǒng)、排煙系統(tǒng)和安全裝置五大部分組成。其結(jié)構(gòu)示意圖如下所示。

（1）水路系統(tǒng)主要包括進(jìn)水閥、水膜閥等，其中水膜閥是關(guān)鍵部件，起控制水氣聯(lián)動(dòng)裝置的作用，當(dāng)水源切斷后立即切斷燃?xì)猓凰y是控制冷水進(jìn)入熱水器流量大小的裝置，水閥燃燒器在同樣工作狀態(tài)下，流量大的，輸出熱水溫較低，反之則水溫升高。

（2）燃?xì)庀到y(tǒng)主要包括燃?xì)庹{(diào)節(jié)閥、水氣聯(lián)動(dòng)閥、常明火、主燃燒器。其中主燃燒器是熱水器供熱的主要部件；水氣聯(lián)動(dòng)閥是由水流的壓力差控制氣閥的開(kāi)啟以防止空燒。燃?xì)庹{(diào)節(jié)閥可調(diào)節(jié)進(jìn)入主燃燒器氣量，以達(dá)到調(diào)節(jié)水溫的目的。

（3）熱交換系統(tǒng)主要包括腔體、集熱片和彎管。

（4）排煙系統(tǒng)包括熱水器外殼、排氣煙管和排煙口等。燃燒后的煙氣，須經(jīng)過(guò)排煙系統(tǒng)排出。

（5）安全裝置主要包括由熱電偶和電磁閥組成的熄火保護(hù)、缺氧保護(hù)、水氣聯(lián)動(dòng)閥防止空燒、排水閥防止過(guò)水壓和凍裂。

下面重點(diǎn)介紹燃?xì)鉄崴髦饕考Y(jié)構(gòu)原理。

一、點(diǎn)火裝置

點(diǎn)火裝置的作用是點(diǎn)燃小火（常明火）并保持其燃燒。當(dāng)按下點(diǎn)火按鈕時(shí)，小火管有燃?xì)饬鞒?，此時(shí)點(diǎn)火器工作，點(diǎn)燃旁邊的小火。燃?xì)鉄崴鞯狞c(diǎn)火方式主要有壓電陶瓷點(diǎn)火和電脈沖點(diǎn)火兩種。

二、水氣聯(lián)動(dòng)閥

水氣聯(lián)動(dòng)閥是保證燃?xì)鉄崴靼踩褂玫闹匾考渲饕饔檬牵寒?dāng)水壓足夠，水在熱交換器中流動(dòng)時(shí)，燃?xì)獠拍苓M(jìn)入主燃燒器進(jìn)行燃燒；而當(dāng)水流停止或壓力不足時(shí)，自動(dòng)切斷燃?xì)夤┙o，以防因缺水面燃?jí)臒崴鳌?

三、燃燒器

1、常明火為點(diǎn)燃主燃燒器作準(zhǔn)備，常明火有單獨(dú)的燃?xì)馔?。同時(shí)常明火加熱熄火保護(hù)裝置中的熱電偶，使電磁閥開(kāi)閉燃?xì)忾y門(mén)。當(dāng)由熱電偶或雙金屬片構(gòu)成的熄火保護(hù)裝置一旦檢測(cè)到常明小火熄滅，熄火保護(hù)裝置將自動(dòng)切斷氣源。

常明火點(diǎn)火管一般用銅管或不銹鋼制成，為保證燃燒的穩(wěn)定，大多采用大氣式燃燒方式，即燃燒前預(yù)混一部分空氣，由于這種燃燒方式火焰短而穩(wěn)定，用它加熱熱電偶或熱雙金屬片時(shí)，熱量集中，不易產(chǎn)生誤動(dòng)作。

2、主燃燒器是燃?xì)鉄崴魈峁嵩吹闹饕考瑹嶝?fù)荷較大，火力強(qiáng)而且集中，火焰高度實(shí)短不宜長(zhǎng)，一般采用大氣式燃燒器來(lái)滿足要求，而且大多不設(shè)一次調(diào)節(jié)裝置。

四、熱交換器

燃?xì)鉄崴鞯臒峤粨Q器主要有兩種類(lèi)型，板管式和翅片管式。由不銹鋼或?qū)嵝粤己玫淖香~片、紫銅管制成。

五、熄火保護(hù)裝置

熄火保護(hù)裝置的主要功能，是在燃?xì)鉄崴鞯狞c(diǎn)火燃燒器（又稱(chēng)常明火）因故熄火后，在數(shù)密封秒鐘后能自動(dòng)動(dòng)作，關(guān)閉燃?xì)忾y門(mén)。有機(jī)械和電磁兩種結(jié)構(gòu)形式，分別稱(chēng)為雙金屬片和熱電偶熄火保護(hù)裝置。

六、缺氧保護(hù)裝置

此裝置上有兩只熱電偶，正向熱電偶與熄火安全裝置熱電偶基本相同（參數(shù)為：25℃內(nèi)阻為（8.8±2）MΩ，700℃熱電勢(shì)20mV）；反向熱電偶由兩根裸露電偶絲組成，材質(zhì)與正向熱電偶相同，但它的工作溫度較低，氧化作用不很明顯，它的安裝位置是保證熱電偶正常工作的重要條件（參數(shù)為：25℃內(nèi)阻18±2MΩ，700℃熱電勢(shì)6mV）。

在使用過(guò)程中，周?chē)h(huán)境氧氣含量不足或換熱器柵板阻塞時(shí)，會(huì)造成燃燒器不完全燃燒，這時(shí)燃燒器火焰拉長(zhǎng)，火焰溫度降低，兩只熱電偶產(chǎn)生的電勢(shì)差較少，當(dāng)環(huán)境氧氣含量低于18%時(shí)，此裝置動(dòng)作，關(guān)閉燃?xì)鈿饴?，避免造成二氧化碳中毒事故，此裝置使用壽命大于6000h，使用次數(shù)大于100000次。

七、防空燒（過(guò)熱）安全裝置

此裝置所用傳感器為正溫度系數(shù)的熱敏電阻。當(dāng)燃?xì)鉄崴鞒霈F(xiàn)空燒時(shí)，因熱敏電阻此時(shí)已呈“高阻”狀態(tài)，使通過(guò)電磁閥電流很小，在彈簧力作用下，鐵心與銜鐵分離，關(guān)閉燃?xì)鈿饴贰?

八、電磁閥

在燃?xì)鉄崴靼踩b置中，燃?xì)鈿饴返耐ā嗍怯呻姶砰y控制的。

九、水溫調(diào)節(jié)裝置

調(diào)溫軸（水閥芯）的控制原理是通過(guò)調(diào)節(jié)水量增減，來(lái)達(dá)到調(diào)節(jié)水溫目的。例如，欲提高淋浴水溫時(shí)，將調(diào)溫軸調(diào)向“高溫”位置，實(shí)際上是關(guān)小水閥芯的開(kāi)啟度，使進(jìn)水量減少，則出口的溫度則會(huì)增加。

十、燃?xì)庑孤﹫?bào)警裝置

當(dāng)燃?xì)鉄崴骰蚺涮自O(shè)備發(fā)生燃?xì)庑孤r(shí)，通過(guò)氣敏傳感器檢測(cè)出一定濃度的燃?xì)猓l(fā)出聲光報(bào)警信號(hào)，提醒用戶排除故障或停止使用，避免造成火災(zāi)或中毒事故。先進(jìn)的泄漏報(bào)警裝置，在報(bào)警的同時(shí)自動(dòng)開(kāi)啟風(fēng)機(jī)通風(fēng)換氣，迅速排除室內(nèi)燃?xì)?，防止事故的發(fā)生和擴(kuò)大。

工作原理

打開(kāi)燃?xì)鈿忾y，燃?xì)膺M(jìn)人閥門(mén)內(nèi)，按動(dòng)點(diǎn)火按鍵，點(diǎn)火微動(dòng)開(kāi)關(guān)、快速微動(dòng)開(kāi)關(guān)啟動(dòng)，點(diǎn)火頭產(chǎn)生連續(xù)電火花，電磁閥線圈強(qiáng)行通人吸合電流，由氣閥桿推動(dòng)，電磁閥被吸住，氣路打開(kāi)，燃?xì)鈴狞c(diǎn)火燃燒器和長(zhǎng)明火燃燒器流出，被點(diǎn)火器的連續(xù)火花點(diǎn)燃，經(jīng)常明火火焰加熱的熄火保護(hù)裝置的熱電偶產(chǎn)生熱電勢(shì)，在強(qiáng)制吸合電流斷開(kāi)時(shí)，保持電磁閥處于吸合狀態(tài)。點(diǎn)火鍵復(fù)位，并關(guān)閉與點(diǎn)火鍵連動(dòng)的點(diǎn)火器閥門(mén)，此時(shí)點(diǎn)火器的火焰熄滅，僅保留常明火焰，這樣，燃?xì)獾竭_(dá)水氣連動(dòng)閥的氣閥前面。

打開(kāi)水龍頭，冷水進(jìn)入水氣連動(dòng)閥的水閥內(nèi)，經(jīng)調(diào)溫旋鈕進(jìn)入熱交換器，同時(shí)有一部分水從調(diào)溫旋鈕分流，進(jìn)人混合管，因水氣連動(dòng)閥內(nèi)的膜片受水壓作用，推開(kāi)水氣連動(dòng)閥的氣閥。燃?xì)饨?jīng)燃?xì)庹{(diào)節(jié)閥、燃燒器調(diào)節(jié)旋鈕，從主燃燒器流出，被常明火點(diǎn)燃。流向熱交換器的水，被主燃燒器的火焰加熱成熱水，經(jīng)混合水管的冷水混合，就可從供熱水龍頭流出適合使用的熱水。

當(dāng)關(guān)閉出水口時(shí)，水氣連動(dòng)閥內(nèi)的壓差消失，從而關(guān)閉了水氣連動(dòng)閥的氣閥，主燃燒器的火焰熄滅，熱水停止流出，按下熄火鍵，點(diǎn)火鍵復(fù)位，關(guān)閉主氣閥，常明火熄滅。此時(shí)熄火安全裝置的熱電偶的熱電勢(shì)下降，電磁閥關(guān)閉。

故障檢修

一、常見(jiàn)故障分析

1、打不著火或打火困難

（1）剛打開(kāi)氣源時(shí)，由于氣管內(nèi)空氣尚未排空，短時(shí)間內(nèi)難以打火，只要多打幾次，讓氣管內(nèi)的空氣排空后，便能成功點(diǎn)火。

（2）噴嘴堵塞：在打火時(shí)有火星，而無(wú)法點(diǎn)燃火種，表明噴嘴有堵塞，此時(shí)只要將噴嘴進(jìn)行清理即可。

（3）點(diǎn)火針破裂或松動(dòng)：多數(shù)熱水器點(diǎn)火針絕緣體是用陶瓷制作的，若陶瓷破裂或點(diǎn)火針?biāo)蓜?dòng)，就會(huì)造成沒(méi)有對(duì)著火種進(jìn)行點(diǎn)火，打不著火。此時(shí)應(yīng)更換點(diǎn)火針或?qū)c(diǎn)火針進(jìn)行調(diào)整位置。

（4）壓電陶瓷失效手動(dòng)式熱水器一般是采用壓電陶瓷點(diǎn)火，若點(diǎn)火時(shí)無(wú)點(diǎn)火火花，通常是壓電陶瓷損壞造成的，應(yīng)及時(shí)進(jìn)行更換。

（5）水動(dòng)式熱水器電磁閥損壞，點(diǎn)火時(shí)，有火星而點(diǎn)不著火，此時(shí)先檢查電磁閥接線是否良好，若未發(fā)現(xiàn)接線不良，應(yīng)更換電磁閥。

（6）水動(dòng)式熱水器點(diǎn)火時(shí)無(wú)火星此時(shí)按順序檢查電池是否有電或裝反，電池盒是否有接觸不良，微動(dòng)開(kāi)關(guān)是否損壞，電脈沖發(fā)生器和接線是否有故障。排除故障后即可點(diǎn)火。

2、中途燎火

（1）熱電偶與電磁閥接觸不良或失效：若在熱水器使用過(guò)程中，偶然中途熄火，說(shuō)明熱電偶與電磁閥接觸不良，此時(shí)應(yīng)緊固兩者的聯(lián)接螺母；當(dāng)熱水器打火后，中途熄火的時(shí)間都較接近時(shí)，表明熱電偶已開(kāi)始失效，應(yīng)盡早更換。當(dāng)熱水器每次中途熄火的時(shí)間不規(guī)則時(shí)，表明火種與熱電偶的位置不太準(zhǔn)確，應(yīng)調(diào)整。

（2）燃?xì)鈿鈮翰环€(wěn)定：適當(dāng)調(diào)整氣源壓力或清洗火種噴嘴。

（3〉保護(hù)裝置動(dòng)作：當(dāng)直排式熱水器使用時(shí)間過(guò)長(zhǎng)，且室內(nèi)換氣較差時(shí)，或熱交換器（水箱）長(zhǎng)期沒(méi)有清洗而造成嚴(yán)重積炭，保護(hù)裝置便會(huì)自動(dòng)關(guān)閉氣源，導(dǎo)致熄火。對(duì)于前者，需打開(kāi)門(mén)窗，使室內(nèi)空氣流通，對(duì)于后者需定期（每年1~2次）清洗熱交換器。

（4）水動(dòng)式熱水器離子感應(yīng)針被污染：若每次使用時(shí)，都要打2~3次火，應(yīng)對(duì)感應(yīng)針進(jìn)行清洗，若經(jīng)清洗，還有同樣的問(wèn)題出現(xiàn)，說(shuō)明感應(yīng)針的材質(zhì)或電子點(diǎn)火器質(zhì)量不良，應(yīng)及時(shí)更換。

3、漏氣

漏氣主要是由于密封用的密封圈破損老化或配合不嚴(yán)造成的。

（1）進(jìn)水接頭安裝不良而漏氣：重新安裝平面膠圈，上緊并緊固氣接頭。

（2）氣閥體上聯(lián)接面漏氣：更換密封膠圈。

（3）氣閥芯上的潤(rùn)滑脂干而漏氣：清洗氣閥芯，重新均勻涂上潤(rùn)滑脂（二硫化鉬），以確保氣閥芯不再漏氣。

4、漏水

（1）防凍排水閥經(jīng)多次拆裝，密封膠圈裂損造成的漏水，應(yīng)更換膠圈，并注意平日裝拆不應(yīng)用力過(guò)大。

（2）水閥芯膠圈因長(zhǎng)期使用磨損嚴(yán)重造成的漏水，只要更換膠圈便可正常使用。

（3）水閥頂軸膠圈處比較容易漏水，若是水動(dòng)式熱水器，水會(huì)直接流到微動(dòng)開(kāi)關(guān)處造成打不著火，因此膠圈磨損，應(yīng)及時(shí)更換。

（4）連接熱水器的冷、熱水軟管和淋浴器的漏水，較易發(fā)現(xiàn)，經(jīng)簡(jiǎn)單維修或更換便能使用。

（5）供水壓力過(guò)高，可更換高壓熱水器或在進(jìn)水閥前加裝節(jié)流閥。

（6）熱水器“空燒”造成漏水。這時(shí)，關(guān)閉熱水器水閥時(shí)，主燃燒器不熄滅，造成“空燒”或回火，易燒化焊錫，嚴(yán)重時(shí)燒穿紫銅管，造成漏水，此故障應(yīng)更換熱盤(pán)管。

5、產(chǎn)生紅火或冒黑煙

（1）燃燒器內(nèi)存污物：將細(xì)鐵絲尖部彎曲，從引射口處插入燃燒器內(nèi)，反復(fù)旋轉(zhuǎn)，進(jìn)行清理。也可將燃燒器拆下來(lái)，用水沖澆。

（2）燃?xì)鈮毫Σ蛔悖簯?yīng)設(shè)法提高其供氣壓力。另外，有時(shí)因天氣潮濕，也會(huì)產(chǎn)生紅火，待天氣好轉(zhuǎn)時(shí)又恢復(fù)正常。

（3）氣路不暢造成缺氧：清理氣路中的異物，并開(kāi)機(jī)（換氣扇、排風(fēng)扇、開(kāi)窗等）通風(fēng)。

6、出水溫度過(guò)低

（1）供氣壓力不足：這是造成出水溫度過(guò)低的主要原因，應(yīng)調(diào)整減壓閥。若是管道燃?xì)?，可通知供氣部門(mén)調(diào)整；若是熱水器流量大，使供氣管或煤氣表負(fù)荷滿足不了熱水器的耗氣量，應(yīng)更換較大的煤氣表或更換流量較小的熱水器。

（2）噴嘴堵塞造成火焰變?。呵謇韲娮?。

（3）水閥橡膠膜有小的破裂：使水氣聯(lián)動(dòng)閥門(mén)開(kāi)度不足，造成燃燒火力不強(qiáng)，出水溫度過(guò)低。應(yīng)更換橡膠膜。

（4）部分地區(qū)水壓較大，使水流經(jīng)熱交換器時(shí)間較短，出水溫度過(guò)低，應(yīng)適當(dāng)調(diào)小水量。

7、火種留不住

（1）火種供氣管堵塞：當(dāng)點(diǎn)燃火種時(shí)，手松開(kāi)也不見(jiàn)火種，爾后能聽(tīng)到電磁閥釋放聲，說(shuō)明火種供氣管堵塞，對(duì)此可進(jìn)行疏通。

（2）熱電偶或電磁閥損壞：檢查時(shí)，按下點(diǎn)火按鈕，不見(jiàn)火種，也聽(tīng)不到電磁閥動(dòng)作聲，說(shuō)明熱電偶或電磁閥損壞。電磁閥的損壞一般是線圈斷路，可用萬(wàn)用表檢查。若電阻為無(wú)窮大，對(duì)此可進(jìn)行更換；對(duì)熱電偶應(yīng)檢查連接導(dǎo)線有無(wú)斷路，再檢查熱電偶是否移位，并擦凈表面氧化物；最后檢查熱電偶是否失效，方法是：將熱電偶從固定夾中卸出懸空，用萬(wàn)用表pA檔串入，用打火機(jī)給熱電偶加熱，15s后若電流很小（接近為0），說(shuō)明熱電偶失效，應(yīng)更換。

（3）熱電偶性能變差：點(diǎn)火按鈕松開(kāi)后有火種，但不久會(huì)自動(dòng)熄滅，是因熱電偶性能變差引起的，這時(shí)可將熱電偶調(diào)到最佳受熱位置，一般就可排除，必要時(shí)，更換熱電偶。

8、主燃燒器不能點(diǎn)燃

（1）水壓不足：引起水壓不足的原因，一是當(dāng)?shù)厮畨翰蛔?，二是雜物堵塞水道。對(duì)于后者可清理過(guò)濾網(wǎng)內(nèi)的雜質(zhì)。

（2）主燃燒器的燃?xì)夤艿辣欢氯哼M(jìn)行疏通。

（3）水氣聯(lián)動(dòng)閥的隔膜室隔膜穿孔：隔膜穿孔后，無(wú)法推動(dòng)頂桿打開(kāi)主燃燒器的燃?xì)忾y塞。修理時(shí)，拆開(kāi)閥體，拆下膜片上的銅螺栓和墊片，更換同規(guī)格的新隔膜。

（4）水氣聯(lián)動(dòng)閥的銅頂桿長(zhǎng)期與水、燃?xì)饨佑|，造成氧化折斷：更換新配件，也可用不銹鋼材料按同樣規(guī)格制成頂桿進(jìn)行更換。

（5）隔膜室螺釘松動(dòng)：松動(dòng)后，造成隔膜室漏水，水壓下降，頂桿無(wú)法打開(kāi)燃?xì)忾y塞，對(duì)此可緊固隔膜室螺釘。效果不好時(shí)，可拆開(kāi)隔膜室，在接合面周?chē)可弦粚诱逞a(bǔ)膠，然后再緊固螺釘，干燥固化后即可使用。

（6）隔膜室中的壓差平衡彈簧折斷：更換新配件。

9、隨著“叭”的一聲響，全機(jī)熄滅

（1）點(diǎn)燃正常10s后出現(xiàn)聲響和熄滅﹑這多是熱電偶損壞造成的。檢查時(shí)，用氣體打火機(jī)燃燒熱電偶尖端，用萬(wàn)用mV檔測(cè)量?jī)啥穗妷海?0mV左右，若為0，說(shuō)明熱電偶損壞，應(yīng)更換。

（2）正常使用10min后，出現(xiàn)聲響和熄滅，這多是缺氧造成的，應(yīng)及時(shí)補(bǔ)充新鮮空氣。

10、關(guān)閉熱水閥后，主燃燒器熄火

（1）燃?xì)忾y塞被水氣連動(dòng)閥頂桿卡住，打開(kāi)水氣連動(dòng)閥，清理閥內(nèi)頂桿表面的水銹，涂上潤(rùn)滑油，重新裝好。

（2）壓差平衡器的眼孔被管道內(nèi)異物堵塞拆開(kāi)閥殼，疏通眼孔。

11、熱水水流不暢、水溫偏高

（1）水溫調(diào)節(jié)旋鈕使用不當(dāng)：檢查水溫旋鈕是否置于需要的位置上，位置有誤時(shí)，應(yīng)予糾正（溫度“最高”為水流最小，溫度“最低”為水流最大）。

（2）水溫調(diào)節(jié)失控：若是旋鈕錯(cuò)位引起閥芯開(kāi)度和指示溫度不一致，應(yīng)及時(shí)調(diào)整，必要時(shí)更換滑牙的旋鈕；水溫控制閥閥桿和閥芯密封件老化損壞時(shí)，會(huì)引起水流不暢，應(yīng)更換密封件。

12、炮火保護(hù)裝置失靈

（1）熱電偶的探頭和點(diǎn)火燃燒器的位置不當(dāng)：調(diào)整時(shí)，可稍松一下固定熱電偶探頭的螺釘，將探頭移至點(diǎn)火燃燒溫度較高的位置，進(jìn)行反復(fù)點(diǎn)火試驗(yàn)，直至電磁閥吸合，再將緊固螺釘擰緊。

（2）熱電偶與電磁閥之間的連接螺母松動(dòng)：將松動(dòng)的螺母擰緊即可。

（3）熱電偶損壞：若熱電偶斷線或發(fā)生在熱點(diǎn)上的短路，一般是無(wú)法修復(fù)的，應(yīng)進(jìn)行更換。方法是：擰開(kāi)與電磁閥連接的螺母，并松開(kāi)探頭在點(diǎn)火燃燒器旁的螺釘，拆下熱電偶。更換新熱電偶時(shí)，先將它與電磁閥連接的螺母擰緊，再將偶線彎成需要的形狀．將探頭固定在點(diǎn)火燃燒器附近溫度較高的位置，裝好后進(jìn)行點(diǎn)火試驗(yàn)，確認(rèn)電磁閥動(dòng)作后，再進(jìn)一步擰緊螺釘、螺母。

（4）電磁閥吸合電流變大：這多是由于銜鐵極面被氣源腐蝕和污染造成的。電磁閥吸合時(shí)間，剛出廠時(shí)，5s即可吸合。使用中的燃?xì)鉄崴?，電磁閥若在點(diǎn)火后30s還不吸合，就應(yīng)進(jìn)行去污或更換處理。

（5）電磁閥線圈斷、短路或銜鐵移位：這類(lèi)故障，一般很難修復(fù)，應(yīng)更換同型號(hào)電磁閥，更換方法見(jiàn)前。

13、調(diào)節(jié)水溫的方法

（1）調(diào)節(jié)進(jìn)氣閥控制燃?xì)膺M(jìn)量，可調(diào)節(jié)水溫。

（2）調(diào)節(jié)水溫調(diào)節(jié)器，可控制出水溫度。

（3）調(diào)節(jié)自來(lái)水閥控制最大水流量，可調(diào)節(jié)最低溫度。

（4）水氣連動(dòng)閥還有自動(dòng)控溫的作用。

14、水垢的清除方法

水垢產(chǎn)生后，會(huì)使熱水器熱效率降低，同時(shí)還會(huì)使熱水器管徑變小，熱水產(chǎn)率下降，水溫過(guò)高，甚至?xí)a(chǎn)生局部堵塞。為此應(yīng)一年左右清洗一次，清洗的方法很多，下面僅介紹一種簡(jiǎn)單實(shí)用的方法。

（1）買(mǎi)一袋鋁壺―次清除水垢劑，將其倒人約1.2L飲料瓶中，并加人約1L溫水，攪拌均勻。

（2〉按圖所示連接好。打開(kāi)水溫開(kāi)關(guān)，用手?jǐn)D壓飲料瓶，待除垢液進(jìn)入熱水器，并從進(jìn)水管流出時(shí)，關(guān)閉水溫開(kāi)關(guān)。

（3）點(diǎn)燃熱水器常明小火，對(duì)除垢液加溫，待10~15min后，關(guān)閉常明小火，打開(kāi)水溫開(kāi)關(guān)，將飲料瓶中剩下的除垢液全部流入熱水器并從進(jìn)水口排出（可重復(fù)幾次）。

（4）卸下飲料瓶，接好進(jìn)水管，打開(kāi)冷水閥門(mén)，用清水將熱水器管道內(nèi)殘余的水垢及除垢液沖洗干凈即可。

15、水動(dòng)式熱水器有水流出，但不點(diǎn)火

水動(dòng)式熱水器是在打開(kāi)進(jìn)水閥門(mén)或熱水閥門(mén)時(shí)，熱水器便會(huì)自動(dòng)點(diǎn)火，數(shù)秒鐘后便有熱水產(chǎn)生。當(dāng)有水流而不點(diǎn)火時(shí)，其故障原因是多種多樣的，可以按以下步驟進(jìn)行檢查并排除故障。

（1）打開(kāi)水源開(kāi)關(guān)，查看指示燈是否有亮，如果紅色亮，表明電池已達(dá)到無(wú)電狀態(tài)，需更換電池；如果綠色亮，但無(wú)“嗒，嗒，嗒”響聲及點(diǎn)火火花，表明點(diǎn)火器高壓包燒毀或高壓線脫落，應(yīng)重新連接高壓線或更換點(diǎn)火器；如果指示燈不亮又無(wú)點(diǎn)火火花出現(xiàn)、應(yīng)檢查有沒(méi)有安裝電池或電池是否裝反，如果電池安裝正常，則需檢查電源連線是否可靠，發(fā)現(xiàn)情況應(yīng)及時(shí)排除。

（2）當(dāng)所有電導(dǎo)線未發(fā)現(xiàn)異常時(shí)，先檢查微動(dòng)開(kāi)關(guān)〈有的熱水器用水動(dòng)磁控開(kāi)關(guān)），用手按動(dòng)微動(dòng)開(kāi)關(guān)或直接用導(dǎo)線（或旋具）進(jìn)行短路連接，此時(shí)如果有點(diǎn)火動(dòng)作，則證明是微動(dòng)開(kāi)關(guān)故障或開(kāi)關(guān)撥片位置不對(duì)，應(yīng)予以更換或調(diào)整。如果按動(dòng)或短路微動(dòng)開(kāi)關(guān)，均無(wú)點(diǎn)火動(dòng)作，則是點(diǎn)火器的故障，需更換點(diǎn)火器。

（3）當(dāng)打開(kāi)水源開(kāi)關(guān)后有點(diǎn)火火花而沒(méi)有著火時(shí)，應(yīng)先檢查點(diǎn)火針位置是否對(duì)準(zhǔn)燃燒器，然后再檢查電磁閥的連線連接是否良好，同時(shí)可根據(jù)該熱水器的用電池情況，對(duì)電磁閥接入3V（或1.5V）的直流電壓，查看燃燒器是否著火，如有著火，則表明點(diǎn)火器輸出電流不足，需更換；如未有著火，則表明電磁閥有故障，也需更換。

（4）如果上述幾種方法都無(wú)法查出原因時(shí)，就要檢查其他的安全保護(hù)裝置，例如，過(guò)熱保護(hù)裝置是否熔斷或開(kāi)路；防止不完全燃燒裝置的熱電偶是否反接或開(kāi)路；水氣聯(lián)動(dòng)裝置是否活動(dòng)自如（反復(fù)開(kāi)、關(guān)水源、微動(dòng)開(kāi)關(guān)撥片應(yīng)左右移動(dòng)，如果不動(dòng)作則是水閥膜片穿孔或聯(lián)動(dòng)桿卡死等）。

（5）在各項(xiàng)檢查前應(yīng)先檢查氣源是否開(kāi)啟，連接氣源的氣管是否折疊或太長(zhǎng)，如果氣管太長(zhǎng)，應(yīng)先多點(diǎn)火幾次，讓氣管內(nèi)的空氣排空后，方可點(diǎn)火成功。

16、開(kāi)水不著火或低溫時(shí)熄火

二、故障代碼與解決方案

現(xiàn)在很多產(chǎn)品都自帶有自檢功能，會(huì)根據(jù)提示告訴你產(chǎn)品出現(xiàn)了什么問(wèn)題，讓用戶能快速找到問(wèn)題，并且解決問(wèn)題，相當(dāng)?shù)闹悄芑诵曰?

保養(yǎng)

一、使用時(shí)應(yīng)經(jīng)常檢查常明火是否正常工作，有無(wú)阻塞；如火焰微弱，應(yīng)立即關(guān)閉燃?xì)鈿庠撮_(kāi)關(guān)，待清除垢物后，再行點(diǎn)燃。

二、熱水器使用一段時(shí)間（一般為半年左右）后，應(yīng)對(duì)水管、燃?xì)夤?、容積式熱水器的水箱等進(jìn)行除垢，以防過(guò)濾網(wǎng)（見(jiàn)下圖）被堵。水箱有沉積物，會(huì)影響熱水器的正常使用。

三、每隔數(shù)月，應(yīng)清除熱水器排氣口、進(jìn)氣排氣筒、熱交換器及周?chē)e炭和灰垢。如果發(fā)現(xiàn)大量積炭或有許多阻塞物時(shí)，可將熱水器卸下，倒過(guò)來(lái)輕輕清除，也可用自來(lái)水沖洗，沖洗時(shí)嚴(yán)禁將水濺到燃燒器噴嘴和常明火上，待干燥后再安裝使用。

四、一般情況下，熱水器使用一年后，應(yīng)對(duì)其做一次全面檢查，查清供氣和供水系統(tǒng)的各個(gè)裝置是否完好、正常，有無(wú)漏氣、漏水等異?，F(xiàn)象。

五、如使用的水質(zhì)較硬，應(yīng)在熱水器的前端裝配一水質(zhì)軟化裝置，并及時(shí)清除熱交換盤(pán)管(即蛇形管）或水箱的水垢。

六、經(jīng)常擦試外殼。

太陽(yáng)能熱水器

結(jié)構(gòu)原理

太陽(yáng)能熱水器一般由集熱器、貯熱裝置、循環(huán)管路、輔助裝置及淋浴噴頭等部分組成。

一、集熱器

集熱器是太陽(yáng)能熱水器的關(guān)鍵部件，其性能好壞，對(duì)熱水器的性能起著決定性的作用。按收集太陽(yáng)能的不同原理，可分為平板型集熱器和聚光型集熱器兩種。聚光型集熱器只能聚集太陽(yáng)的直射輻射能，需要對(duì)太陽(yáng)進(jìn)行跟蹤，增加了裝置成本，只有在需要附到較高溫度等特殊場(chǎng)合使用；平板型集熱器是目前應(yīng)用較廣泛的一種，它不僅能吸收太陽(yáng)的直射輻射，還可以收集太剛的散射輻射。

二、貯熱裝置

貯熱裝置通常作為短期貯存熱水、減少熱損失的容器，貯熱效果主要取決于裝置保溫性能的好壞。

三、循環(huán)管路

循環(huán)管路的作用是連通集熱器、貯熱水箱，形成一個(gè)完整的循環(huán)加熱系統(tǒng)。

四、輔助裝置

輔助裝置的作用是使整個(gè)熱水器裝置能正常工作，并通過(guò)儀表加以顯示。輔助裝置包括水位顯示裝置、溫度顯示裝置、循環(huán)泵、控制系統(tǒng)及輔助熱源等。

故障檢修

一、太陽(yáng)能熱水器的常見(jiàn)故障及排除方法見(jiàn)下表。

二、故障代碼與解決方案

保養(yǎng)

必須經(jīng)常保持集熱器上蓋的清潔；要防止空曬；使用一定時(shí)間后，應(yīng)進(jìn)行清潔處理，排除沉積的污垢；冬季停用時(shí)，必須將集熱器及管道中的水排凈，以防凍裂。

以上就是對(duì)熱水器如何維修問(wèn)題的介紹，希望能對(duì)您有所幫助！
