5. 手表上的CA是什么意思
Ca有四個不同釋義,具體如下:
1、CA:美國《化學文摘》
《化學文摘》簡稱CA,是世界最大的化學文摘庫。也是目前世界上應(yīng)用最廣泛,最為重要的化學、化工及相關(guān)學科的檢索工具。創(chuàng)刊于1907年,由美國化學學會化學文摘社(Chemical Abstracts Service,CAS)編輯出版,.CA報道的內(nèi)容幾乎涉及了化學家感興趣的所有領(lǐng)域。
其中除包括無機化學、有機化學、分析化學、物理化學、高分子化學外,還包括冶金學、地球化學、藥物學、毒物學、環(huán)境化學、生物學以及物理學等諸多學科領(lǐng)域。CA特點:收藏信息量大、收錄范圍廣。
2、CA:化學元素符號
CA(化學元素符號)指鈣,鈣是一種金屬元素,符號Ca,在化學元素周期表中位于第4周期、第IIA族,常溫下呈銀白色晶體。動物的骨骼、蛤殼、蛋殼都含有碳酸鈣??捎糜诤辖鸬拿撗鮿?、油類的脫水劑、冶金的還原劑、鐵和鐵合金的脫硫與脫碳劑以及電子管中的吸氣劑等。
3、CA:產(chǎn)生和確定數(shù)字證書的第三方可信機構(gòu)
CA指CA證書,網(wǎng)上的公眾用戶通過驗證 CA 的簽字從而信任 CA ,任何人都可以得到 CA 的證書(含公鑰),用以驗證它所簽發(fā)的證書。
如果用戶想得到一份屬于自己的證書,他應(yīng)先向 CA 提出申請。在 CA 判明申請者的身份后,便為他分配一個公鑰,并且 CA 將該公鑰與申請者的身份信息綁在一起,并為之簽字后,便形成證書發(fā)給申請者。
如果一個用戶想鑒別另一個證書的真?zhèn)危陀?CA 的公鑰對那個證書上的簽字進行驗證,一旦驗證通過,該證書就被認為是有效的。證書實際是由證書簽證機關(guān)(CA)簽發(fā)的對用戶的公鑰的認證。
4、CA:醫(yī)學術(shù)語簡寫
CA是癌癥cancer的簡寫,即惡性腫瘤,醫(yī)院里經(jīng)常用該詞代替癌癥。如,肝Ca,肺Ca,轉(zhuǎn)移性胃Ca等。為了避諱,畢竟有些人還是很害怕“癌”這個字的。
雖然患者具有知情權(quán),國內(nèi)的醫(yī)生還是盡量照顧患者及其家屬,一般不書寫癌癥(在患者可以看到的資料上,如影像報告,床頭卡,檢驗報告等)

熱水器已成為生活中重要的一部分,給人們的生活帶來極大的方便。但由于元器件自然老化、操作者的熟練程度、工作環(huán)境和工作強度等諸多因素常引發(fā)各類故障。接下來就為大家介紹如何維修熱水器的問題。
電熱水器
工作原理
電熱水器具有結(jié)構(gòu)簡單、價格低、熱效率高、無污染、使用方便等優(yōu)點,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3kW以上,且易漏電,很少有人問津;貯水式一般功率在1~2kW之間,安全方便,受到消費者喜愛。
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)和進出水系統(tǒng)四大部分組成。下面為部分國產(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,又是對外加熱的場所,其壽命決定于內(nèi)膽的材料和制造工藝。常見內(nèi)膽材料有鍍鋅鐵板、不銹鋼板和鋼板內(nèi)涂搪瓷三種。
(3)陽級棒
貯水式電熱水器中的陽極棒是一根金屬鎂棒,主要用來保護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,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、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,金屬護套管常見為不銹鋼管或銅管。電加熱管在通電后,其內(nèi)部高電阻電熱合金絲發(fā)熱,通過金屬管內(nèi)的絕緣填充料導熱至金屬套管,起加熱作用。
電加熱管使用時間一長,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)熱周圍的空氣,然后通過鋼板對水加熱),使水電分離,不僅無漏電之憂,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)漏電保護器
在電熱水器的漏電保護器中、將15mA確定為危險電流,超過這一數(shù)值時漏電保護器動作,正常的動作范圍為15~30mA。
海爾電熱水器選用的是進口漏電保護器,動作值為15mA,動作時間為0.1s。小鴨等品牌電熱水器電源線帶有先進的電子控制漏電保護插頭,其技術(shù)參數(shù)為:額定電壓220V(5OHz),額定電流10A,漏電動作范圍5~10mA,漏電動作時間≤50ms,最大分斷能力300A,最大負載功率2200W。
4、進、出水系統(tǒng)
進、出水系統(tǒng)由進、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、熱閥門控制膽內(nèi)壓力,故稱為出口敞開式。
單獨打開右側(cè)紅點熱水旋閥,自來水經(jīng)出水管、混合閥、噴頭流出,出熱水,出水壓力由熱水閥控制;單獨打開左側(cè)藍點冷水旋閥,自來水直接經(jīng)混合閥由噴頭流出冷水,出水壓力由冷水閥控制。當同時打開冷熱水閥門時,冷水和熱水在混合閥出水口混合,適當調(diào)節(jié)冷熱水閥門大小,可得到所需水溫。
(2)安全閥
在自來水壓力突然增高或加熱水溫過熱,造成內(nèi)膽壓力超過規(guī)定耐壓值時,安全閥會自動排壓,以保護內(nèi)膽。在加熱過程中,安全閥會有緩慢的滴水現(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、開啟水閥后,僅需十幾秒就會有充足的熱水源源流出,因此也稱流動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、壓力開關(guān)和溫度控制等部分組成。
2、工作原理
(1)腔體式
打開進水閥門,水流入腔體。當水充滿腔體后,在水壓和重力作用下,使橡皮膜下凹,從而帶動通過膜片中心的通水管子上端,使觸點閉合接通電源,這樣電阻絲通電發(fā)熱,被加熱的水沿通水管上開有的小孔流入管內(nèi),再經(jīng)過蓮蓬頭噴射出來,供人們使用。當停止進水時,靠橡皮膜彈力恢復使觸頭斷開,從而切斷電源。
(2)水槽式
在未接通水源時,壓力開關(guān)處于常態(tài)(觸點斷開),微動開關(guān)s不動作,從而繼電器線圈不通電,這時整機不工作。接通水源后,因水壓升高,這時壓力開關(guān)觸點動作,繼電器KA吸合,主電路觸點閉合,指示燈HL點亮,這時只要將轉(zhuǎn)換開關(guān)(功率調(diào)節(jié)器)根據(jù)需要調(diào)節(jié)在適當位置,電熱元件即可工作,就會有熱水從蓮蓬頭中源源不斷流出。
常見故障分析
一、電熱水器檢修工藝
下面以海爾電熱水器為例,對電熱水器的檢修工藝過程介紹如下:
1、電源檢查
用萬用表交流電壓檔(~500V檔)測量插座零線和火線,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。
(萬用表使用方法圖解)
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:待半小時左右,水溫升高10℃左右,說明熱水器正常;若水溫不升高,由燈亮可知,漏電保護器、超溫管均正常,故障在加熱器。斷電后,檢測加熱元件,若電阻為無窮大,應(yīng)更換。
(2)指示燈不亮:若燈壞應(yīng)更換;燈好時,應(yīng)檢查溫控器、超溫管、加熱器和漏電保護器以確定故障所在。
①對可調(diào)溫型溫控器,用萬用表R×1檔測量,在關(guān)斷位置電阻為無窮大;在不同溫度控制點應(yīng)有不同電阻值與之對應(yīng);溫控器在未動作時,觸點為閉合狀態(tài),電阻近似為0,否則說明溫控器損壞,應(yīng)更換。
(萬用表測量溫控器圖解)
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用萬用表檢測加熱器,電阻約24~48Ω,若為無窮大時,應(yīng)更換加熱元件。
④檢查漏電保護器,應(yīng)將漏電保護器打到合閘位置,燈亮,水溫升高為正常;有時漏電保護器誤動作,應(yīng)注意觀察,找出誤動作原因。
(漏電保護器“合閘”狀態(tài))
若漏電保護器合不上閘,應(yīng)用萬用表R×100檔依次檢測超溫管、溫控器和加熱器的對地電阻,表針指向∞位置為正常,表針指向0為漏電,找出漏電元件進行更換,若無漏電元件,說明漏電保護器已損壞,更換新的。
(漏電保護器“跳閘”狀態(tài))
3、安全性能測試
(1)漏電測試:重新合閘,按“試驗”按鈕應(yīng)跳閘,漏電保護器為正常,再“合閘”燈亮。若熱水器無漏電保護器,用萬用表電阻檔測量插頭的火線與地線、零線和地線,若指示為無窮大,說明無漏電現(xiàn)象。
(2)泄漏電流測試:泄漏電流不應(yīng)超過規(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、電熱水器常見故障分析
1、出水不熱
(1)冷熱水調(diào)節(jié)不當:這是由于熱水閥開得太小,冷水閥開得太大造成的。應(yīng)適當調(diào)節(jié)冷熱水閥的開度,使出水溫度適合使用。
(2)電源未接通:調(diào)整電源插頭或開關(guān),使其接觸良好。若采用的是漏電保護插頭,應(yīng)將其“復位按鈕”按下,排除以上故障若仍不能接通電源,應(yīng)拆開電熱水器仔細檢查回路是否有導線脫落、斷開等情況,若有,應(yīng)及時排除。
(3)電加熱器損壞:用萬用表電阻檔測量電熱元件電阻值,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。若電阻為無窮大,說明電熱元件損壞,應(yīng)予更換。
(4)溫控器損壞:當溫控器觸頭接觸不良或感溫體內(nèi)感溫劑泄漏時,可引起溫控器不能正常工作。對于前者可拆開壓力式溫控器進行修復;對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:適當調(diào)節(jié)冷熱水閥的開度。
(2)溫控器旋鈕調(diào)節(jié)不當或觸點粘連:將溫控器旋鈕調(diào)至溫度較低處;對觸點粘連的,可將溫控器拆開,將粘連觸點分開,并對觸點進行研修、調(diào)整,經(jīng)調(diào)整后,一般即可使用,必要時可進行更換。
(3)限溫器失靈:檢修限溫器。
3、漏水
(1)管道連接處漏水:對接口密封不好造成的漏水,應(yīng)重新安裝接口;若屬自來水壓太高,應(yīng)在自來水道上設(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,更換時要保持電氣接觸良好,有關(guān)密封部分不漏水。
(4)內(nèi)部導線絕緣層損壞,搭接在外殼或內(nèi)膽上:拆開電熱水器,檢查出導線絕緣層損壞的部分,進行更換。
5、進水困難
(1)臟堵:主要是由于自來水水質(zhì)不好,雜質(zhì)超量,堵住進水口的逆止閥。設(shè)有進水濾網(wǎng)的熱水器大都是濾網(wǎng)孔被堵。在確定水壓正常后,關(guān)閉自來水供水總閥,清理管路,沖出勝物或清洗濾網(wǎng)。
(2)汽堵:常見于密閉水箱貯水式電熱水器中。其特征是:熱水閥打開后,噴出大量水蒸氣,此時應(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,然后打開冷水進水閥,使熱水器排水,降低水溫,再檢修溫控器;若熱水閥打開后,熱汽斷續(xù)流出,量很小,一般是臟堵造成的。此時應(yīng)開大熱水閥和冷水進水閥,以降低水溫,待水溫降低后,檢查熱水閥是否臟堵,洗凈后冷水便會從熱水閥流出。
(3)供水壓力不正常:當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,會造成進水困難。這種故障,待水壓正常后,故障即自行消失。
保養(yǎng)
使用一段時間后,應(yīng)取下噴頭,按安裝方法進行沖洗。長期使用后,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)檢查修復后再用。
加熱時因水的膨脹,噴頭有時會有少量熱水溢出,這屬正常現(xiàn)象,不必過分用力擰緊熱水閥,以免加速損壞密封圈。
自來水閥可使用不帶手輪的閥門或者安裝好后取下手輪,以防誤關(guān)此閥,導致水箱缺水而燒毀電熱絲。
燃氣熱水器
結(jié)構(gòu)
目前,家用快速燃氣熱水器常見為壁掛式,適合淋浴使用,主要由水路系統(tǒng)、燃氣系統(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)動裝置的作用,當水源切斷后立即切斷燃氣;水閥是控制冷水進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)燃氣系統(tǒng)主要包括燃氣調(diào)節(jié)閥、水氣聯(lián)動閥、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)動閥是由水流的壓力差控制氣閥的開啟以防止空燒。燃氣調(diào)節(jié)閥可調(diào)節(jié)進入主燃燒器氣量,以達到調(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、缺氧保護、水氣聯(lián)動閥防止空燒、排水閥防止過水壓和凍裂。
下面重點介紹燃氣熱水器主要部件結(jié)構(gòu)原理。
一、點火裝置
點火裝置的作用是點燃小火(常明火)并保持其燃燒。當按下點火按鈕時,小火管有燃氣流出,此時點火器工作,點燃旁邊的小火。燃氣熱水器的點火方式主要有壓電陶瓷點火和電脈沖點火兩種。
二、水氣聯(lián)動閥
水氣聯(lián)動閥是保證燃氣熱水器安全使用的重要部件,其主要作用是:當水壓足夠,水在熱交換器中流動時,燃氣才能進入主燃燒器進行燃燒;而當水流停止或壓力不足時,自動切斷燃氣供給,以防因缺水面燃壞熱水器。
三、燃燒器
1、常明火為點燃主燃燒器作準備,常明火有單獨的燃氣通路。同時常明火加熱熄火保護裝置中的熱電偶,使電磁閥開閉燃氣閥門。當由熱電偶或雙金屬片構(gòu)成的熄火保護裝置一旦檢測到常明小火熄滅,熄火保護裝置將自動切斷氣源。
常明火點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,熱量集中,不易產(chǎn)生誤動作。
2、主燃燒器是燃氣熱水器提供熱源的主要部件,熱負荷較大,火力強而且集中,火焰高度實短不宜長,一般采用大氣式燃燒器來滿足要求,而且大多不設(shè)一次調(diào)節(jié)裝置。
四、熱交換器
燃氣熱水器的熱交換器主要有兩種類型,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、熄火保護裝置
熄火保護裝置的主要功能,是在燃氣熱水器的點火燃燒器(又稱常明火)因故熄火后,在數(shù)密封秒鐘后能自動動作,關(guān)閉燃氣閥門。有機械和電磁兩種結(jié)構(gòu)形式,分別稱為雙金屬片和熱電偶熄火保護裝置。
六、缺氧保護裝置
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6mV)。
在使用過程中,周圍環(huán)境氧氣含量不足或換熱器柵板阻塞時,會造成燃燒器不完全燃燒,這時燃燒器火焰拉長,火焰溫度降低,兩只熱電偶產(chǎn)生的電勢差較少,當環(huán)境氧氣含量低于18%時,此裝置動作,關(guān)閉燃氣氣路,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。當燃氣熱水器出現(xiàn)空燒時,因熱敏電阻此時已呈“高阻”狀態(tài),使通過電磁閥電流很小,在彈簧力作用下,鐵心與銜鐵分離,關(guān)閉燃氣氣路。
八、電磁閥
在燃氣熱水器安全裝置中,燃氣氣路的通、斷是由電磁閥控制的。
九、水溫調(diào)節(jié)裝置
調(diào)溫軸(水閥芯)的控制原理是通過調(diào)節(jié)水量增減,來達到調(diào)節(jié)水溫目的。例如,欲提高淋浴水溫時,將調(diào)溫軸調(diào)向“高溫”位置,實際上是關(guān)小水閥芯的開啟度,使進水量減少,則出口的溫度則會增加。
十、燃氣泄漏報警裝置
當燃氣熱水器或配套設(shè)備發(fā)生燃氣泄漏時,通過氣敏傳感器檢測出一定濃度的燃氣,發(fā)出聲光報警信號,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。先進的泄漏報警裝置,在報警的同時自動開啟風機通風換氣,迅速排除室內(nèi)燃氣,防止事故的發(fā)生和擴大。
工作原理
打開燃氣氣閥,燃氣進人閥門內(nèi),按動點火按鍵,點火微動開關(guān)、快速微動開關(guān)啟動,點火頭產(chǎn)生連續(xù)電火花,電磁閥線圈強行通人吸合電流,由氣閥桿推動,電磁閥被吸住,氣路打開,燃氣從點火燃燒器和長明火燃燒器流出,被點火器的連續(xù)火花點燃,經(jīng)常明火火焰加熱的熄火保護裝置的熱電偶產(chǎn)生熱電勢,在強制吸合電流斷開時,保持電磁閥處于吸合狀態(tài)。點火鍵復位,并關(guān)閉與點火鍵連動的點火器閥門,此時點火器的火焰熄滅,僅保留常明火焰,這樣,燃氣到達水氣連動閥的氣閥前面。
打開水龍頭,冷水進入水氣連動閥的水閥內(nèi),經(jīng)調(diào)溫旋鈕進入熱交換器,同時有一部分水從調(diào)溫旋鈕分流,進人混合管,因水氣連動閥內(nèi)的膜片受水壓作用,推開水氣連動閥的氣閥。燃氣經(jīng)燃氣調(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。
當關(guān)閉出水口時,水氣連動閥內(nèi)的壓差消失,從而關(guān)閉了水氣連動閥的氣閥,主燃燒器的火焰熄滅,熱水停止流出,按下熄火鍵,點火鍵復位,關(guān)閉主氣閥,常明火熄滅。此時熄火安全裝置的熱電偶的熱電勢下降,電磁閥關(guān)閉。

故障檢修
一、常見故障分析
1、打不著火或打火困難
(1)剛打開氣源時,由于氣管內(nèi)空氣尚未排空,短時間內(nèi)難以打火,只要多打幾次,讓氣管內(nèi)的空氣排空后,便能成功點火。
(2)噴嘴堵塞:在打火時有火星,而無法點燃火種,表明噴嘴有堵塞,此時只要將噴嘴進行清理即可。
(3)點火針破裂或松動:多數(shù)熱水器點火針絕緣體是用陶瓷制作的,若陶瓷破裂或點火針松動,就會造成沒有對著火種進行點火,打不著火。此時應(yīng)更換點火針或?qū)c火針進行調(diào)整位置。
(4)壓電陶瓷失效手動式熱水器一般是采用壓電陶瓷點火,若點火時無點火火花,通常是壓電陶瓷損壞造成的,應(yīng)及時進行更換。
(5)水動式熱水器電磁閥損壞,點火時,有火星而點不著火,此時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)水動式熱水器點火時無火星此時按順序檢查電池是否有電或裝反,電池盒是否有接觸不良,微動開關(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:若在熱水器使用過程中,偶然中途熄火,說明熱電偶與電磁閥接觸不良,此時應(yīng)緊固兩者的聯(lián)接螺母;當熱水器打火后,中途熄火的時間都較接近時,表明熱電偶已開始失效,應(yīng)盡早更換。當熱水器每次中途熄火的時間不規(guī)則時,表明火種與熱電偶的位置不太準確,應(yīng)調(diào)整。
(2)燃氣氣壓不穩(wěn)定:適當調(diào)整氣源壓力或清洗火種噴嘴。
(3〉保護裝置動作:當直排式熱水器使用時間過長,且室內(nèi)換氣較差時,或熱交換器(水箱)長期沒有清洗而造成嚴重積炭,保護裝置便會自動關(guān)閉氣源,導致熄火。對于前者,需打開門窗,使室內(nèi)空氣流通,對于后者需定期(每年1~2次)清洗熱交換器。
(4)水動式熱水器離子感應(yīng)針被污染:若每次使用時,都要打2~3次火,應(yīng)對感應(yīng)針進行清洗,若經(jīng)清洗,還有同樣的問題出現(xiàn),說明感應(yīng)針的材質(zhì)或電子點火器質(zhì)量不良,應(yīng)及時更換。
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造成的。
(1)進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)氣閥芯上的潤滑脂干而漏氣:清洗氣閥芯,重新均勻涂上潤滑脂(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)用力過大。
(2)水閥芯膠圈因長期使用磨損嚴重造成的漏水,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,若是水動式熱水器,水會直接流到微動開關(guān)處造成打不著火,因此膠圈磨損,應(yīng)及時更換。
(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)簡單維修或更換便能使用。
(5)供水壓力過高,可更換高壓熱水器或在進水閥前加裝節(jié)流閥。
(6)熱水器“空燒”造成漏水。這時,關(guān)閉熱水器水閥時,主燃燒器不熄滅,造成“空燒”或回火,易燒化焊錫,嚴重時燒穿紫銅管,造成漏水,此故障應(yīng)更換熱盤管。
5、產(chǎn)生紅火或冒黑煙
(1)燃燒器內(nèi)存污物:將細鐵絲尖部彎曲,從引射口處插入燃燒器內(nèi),反復旋轉(zhuǎn),進行清理。也可將燃燒器拆下來,用水沖澆。
(2)燃氣壓力不足:應(yīng)設(shè)法提高其供氣壓力。另外,有時因天氣潮濕,也會產(chǎn)生紅火,待天氣好轉(zhuǎn)時又恢復正常。
(3)氣路不暢造成缺氧:清理氣路中的異物,并開機(換氣扇、排風扇、開窗等)通風。
6、出水溫度過低
(1)供氣壓力不足:這是造成出水溫度過低的主要原因,應(yīng)調(diào)整減壓閥。若是管道燃氣,可通知供氣部門調(diào)整;若是熱水器流量大,使供氣管或煤氣表負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)動閥門開度不足,造成燃燒火力不強,出水溫度過低。應(yīng)更換橡膠膜。
(4)部分地區(qū)水壓較大,使水流經(jīng)熱交換器時間較短,出水溫度過低,應(yīng)適當調(diào)小水量。
7、火種留不住
(1)火種供氣管堵塞:當點燃火種時,手松開也不見火種,爾后能聽到電磁閥釋放聲,說明火種供氣管堵塞,對此可進行疏通。
(2)熱電偶或電磁閥損壞:檢查時,按下點火按鈕,不見火種,也聽不到電磁閥動作聲,說明熱電偶或電磁閥損壞。電磁閥的損壞一般是線圈斷路,可用萬用表檢查。若電阻為無窮大,對此可進行更換;對熱電偶應(yīng)檢查連接導線有無斷路,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,用萬用表pA檔串入,用打火機給熱電偶加熱,15s后若電流很?。ń咏鼮?),說明熱電偶失效,應(yīng)更換。
(3)熱電偶性能變差:點火按鈕松開后有火種,但不久會自動熄滅,是因熱電偶性能變差引起的,這時可將熱電偶調(diào)到最佳受熱位置,一般就可排除,必要時,更換熱電偶。
8、主燃燒器不能點燃
(1)水壓不足:引起水壓不足的原因,一是當?shù)厮畨翰蛔悖请s物堵塞水道。對于后者可清理過濾網(wǎng)內(nèi)的雜質(zhì)。
(2)主燃燒器的燃氣管道被堵塞:進行疏通。
(3)水氣聯(lián)動閥的隔膜室隔膜穿孔:隔膜穿孔后,無法推動頂桿打開主燃燒器的燃氣閥塞。修理時,拆開閥體,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)動閥的銅頂桿長期與水、燃氣接觸,造成氧化折斷:更換新配件,也可用不銹鋼材料按同樣規(guī)格制成頂桿進行更換。
(5)隔膜室螺釘松動:松動后,造成隔膜室漏水,水壓下降,頂桿無法打開燃氣閥塞,對此可緊固隔膜室螺釘。效果不好時,可拆開隔膜室,在接合面周圍涂上一層粘補膠,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,全機熄滅
(1)點燃正常10s后出現(xiàn)聲響和熄滅﹑這多是熱電偶損壞造成的。檢查時,用氣體打火機燃燒熱電偶尖端,用萬用mV檔測量兩端電壓,正常為20mV左右,若為0,說明熱電偶損壞,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)及時補充新鮮空氣。
10、關(guān)閉熱水閥后,主燃燒器熄火
(1)燃氣閥塞被水氣連動閥頂桿卡住,打開水氣連動閥,清理閥內(nèi)頂桿表面的水銹,涂上潤滑油,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:檢查水溫旋鈕是否置于需要的位置上,位置有誤時,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:若是旋鈕錯位引起閥芯開度和指示溫度不一致,應(yīng)及時調(diào)整,必要時更換滑牙的旋鈕;水溫控制閥閥桿和閥芯密封件老化損壞時,會引起水流不暢,應(yīng)更換密封件。
12、炮火保護裝置失靈
(1)熱電偶的探頭和點火燃燒器的位置不當:調(diào)整時,可稍松一下固定熱電偶探頭的螺釘,將探頭移至點火燃燒溫度較高的位置,進行反復點火試驗,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:將松動的螺母擰緊即可。
(3)熱電偶損壞:若熱電偶斷線或發(fā)生在熱點上的短路,一般是無法修復的,應(yīng)進行更換。方法是:擰開與電磁閥連接的螺母,并松開探頭在點火燃燒器旁的螺釘,拆下熱電偶。更換新熱電偶時,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.將探頭固定在點火燃燒器附近溫度較高的位置,裝好后進行點火試驗,確認電磁閥動作后,再進一步擰緊螺釘、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。電磁閥吸合時間,剛出廠時,5s即可吸合。使用中的燃氣熱水器,電磁閥若在點火后30s還不吸合,就應(yīng)進行去污或更換處理。
(5)電磁閥線圈斷、短路或銜鐵移位:這類故障,一般很難修復,應(yīng)更換同型號電磁閥,更換方法見前。
13、調(diào)節(jié)水溫的方法
(1)調(diào)節(jié)進氣閥控制燃氣進量,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)自來水閥控制最大水流量,可調(diào)節(jié)最低溫度。
(4)水氣連動閥還有自動控溫的作用。
14、水垢的清除方法
水垢產(chǎn)生后,會使熱水器熱效率降低,同時還會使熱水器管徑變小,熱水產(chǎn)率下降,水溫過高,甚至會產(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,下面僅介紹一種簡單實用的方法。
(1)買一袋鋁壺―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。打開水溫開關(guān),用手擠壓飲料瓶,待除垢液進入熱水器,并從進水管流出時,關(guān)閉水溫開關(guān)。
(3)點燃熱水器常明小火,對除垢液加溫,待10~15min后,關(guān)閉常明小火,打開水溫開關(guān),將飲料瓶中剩下的除垢液全部流入熱水器并從進水口排出(可重復幾次)。
(4)卸下飲料瓶,接好進水管,打開冷水閥門,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、水動式熱水器有水流出,但不點火
水動式熱水器是在打開進水閥門或熱水閥門時,熱水器便會自動點火,數(shù)秒鐘后便有熱水產(chǎn)生。當有水流而不點火時,其故障原因是多種多樣的,可以按以下步驟進行檢查并排除故障。
(1)打開水源開關(guān),查看指示燈是否有亮,如果紅色亮,表明電池已達到無電狀態(tài),需更換電池;如果綠色亮,但無“嗒,嗒,嗒”響聲及點火火花,表明點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火器;如果指示燈不亮又無點火火花出現(xiàn)、應(yīng)檢查有沒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)及時排除。
(2)當所有電導線未發(fā)現(xiàn)異常時,先檢查微動開關(guān)〈有的熱水器用水動磁控開關(guān)),用手按動微動開關(guān)或直接用導線(或旋具)進行短路連接,此時如果有點火動作,則證明是微動開關(guān)故障或開關(guān)撥片位置不對,應(yīng)予以更換或調(diào)整。如果按動或短路微動開關(guān),均無點火動作,則是點火器的故障,需更換點火器。
(3)當打開水源開關(guān)后有點火火花而沒有著火時,應(yīng)先檢查點火針位置是否對準燃燒器,然后再檢查電磁閥的連線連接是否良好,同時可根據(jù)該熱水器的用電池情況,對電磁閥接入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法查出原因時,就要檢查其他的安全保護裝置,例如,過熱保護裝置是否熔斷或開路;防止不完全燃燒裝置的熱電偶是否反接或開路;水氣聯(lián)動裝置是否活動自如(反復開、關(guān)水源、微動開關(guān)撥片應(yīng)左右移動,如果不動作則是水閥膜片穿孔或聯(lián)動桿卡死等)。
(5)在各項檢查前應(yīng)先檢查氣源是否開啟,連接氣源的氣管是否折疊或太長,如果氣管太長,應(yīng)先多點火幾次,讓氣管內(nèi)的空氣排空后,方可點火成功。
16、開水不著火或低溫時熄火
(1)水壓偏低因水壓低,而無法打開水氣聯(lián)動閥,燃氣就無法出來被點燃。
(2)水閥的橡膠薄膜破損、變形或偏心更換橡膠薄膜。
(3)進水管濾網(wǎng)堵塞、淋浴噴頭堵塞以及水閥內(nèi)的文氏管松動︰平時必須經(jīng)常清理。使熱水器保持較佳使用狀態(tài)。
17、開水熄火或未開水著火
(1)冷熱水閥門漏水或關(guān)閉不嚴,使熱水器內(nèi)有一定水壓,打開水氣聯(lián)動閥而造成此故障更換或關(guān)嚴冷、熱水閥門。
(2)水氣聯(lián)動閥內(nèi)頂桿被卡死,或長期停用頂桿被粘著,膠圈變形造成頂桿運動緩慢而不熄火拆下頂桿清洗,并加潤滑油。
(3)水氣聯(lián)動閥的氣閥門彈簧器日久彈力不足更換彈簧。
(4)水閥進水管因無濾網(wǎng),造成雜質(zhì)卡死水閥頂軸而不炮火﹑先清洗干凈水閥內(nèi)部,再在進水管補加濾網(wǎng),以保證水質(zhì)干凈。
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,會根據(jù)提示告訴你產(chǎn)品出現(xiàn)了什么問題,讓用戶能快速找到問題,并且解決問題,相當?shù)闹悄芑诵曰?
保養(yǎng)
一、使用時應(yīng)經(jīng)常檢查常明火是否正常工作,有無阻塞;如火焰微弱,應(yīng)立即關(guān)閉燃氣氣源開關(guān),待清除垢物后,再行點燃。
二、熱水器使用一段時間(一般為半年左右)后,應(yīng)對水管、燃氣管、容積式熱水器的水箱等進行除垢,以防過濾網(wǎng)(見下圖)被堵。水箱有沉積物,會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、進氣排氣筒、熱交換器及周圍積炭和灰垢。如果發(fā)現(xiàn)大量積炭或有許多阻塞物時,可將熱水器卸下,倒過來輕輕清除,也可用自來水沖洗,沖洗時嚴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)對其做一次全面檢查,查清供氣和供水系統(tǒng)的各個裝置是否完好、正常,有無漏氣、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,并及時清除熱交換盤管(即蛇形管)或水箱的水垢。
六、經(jīng)常擦試外殼。
太陽能熱水器
結(jié)構(gòu)原理
太陽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
集熱器是太陽能熱水器的關(guān)鍵部件,其性能好壞,對熱水器的性能起著決定性的作用。按收集太陽能的不同原理,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的直射輻射能,需要對太陽進行跟蹤,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熱水器裝置能正常工作,并通過儀表加以顯示。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、太陽能熱水器的常見故障及排除方法見下表。
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;使用一定時間后,應(yīng)進行清潔處理,排除沉積的污垢;冬季停用時,必須將集熱器及管道中的水排凈,以防凍裂。
以上就是對熱水器如何維修問題的介紹,希望能對您有所幫助!
