style="font-size:16px;">這時用燈泡代替行供電電阻。在開機后發(fā)現(xiàn)彩行有打火的現(xiàn)象，但如果不開機就無法知道，因為用肉眼還無法看到打火燒毀的痕跡。但此時有了燈泡的限流和降壓，使行管工作在較低的電壓環(huán)境下，對行管的安全也有了一些保障。所以，在確定了打火的時候，并沒有引起故障的擴大。在燈泡功率的選取上，也要根據(jù)電源的功率大小做一些靈活的掌握。一般在40~100W之間選擇，對于一些特大屏幕的可用150w以上的。隨著人們生活水平的不斷提高，越來越多的家用電器開始進入到人們的生活中去現(xiàn)在每個家庭里都有很多家用電器，沒壞的時候自然很好，可一旦壞了那就麻煩了。那么面對這么多的電器，我們該如何維修呢?在維修家電前，首先要詢問產(chǎn)生故障的前后經(jīng)過以及故障現(xiàn)象，根據(jù)用戶提供的情況和線索，再認真地對</span><span style="font-size:16px;">電路進行分析研究，弄通弄懂其電路原理和元器件的作用，做到心中有數(shù)，有的放矢。</span> </p><p> <span style="font-size:16px;">如果是初次接觸，有些修理工會故意給你一些甜頭。比如，向你展現(xiàn)熱情的服務態(tài)度，初次上門先是收取較低的費用，但其實這都是"障眼法"。這樣的維修工會在維修的過程中，趁你放松警惕不注意時"暗渡陳倉"，故意在你送去維修的家電上"預留"故障，讓家電在不久后又出新的問題。一般的家電維修門店同時也回收舊家電，把幾十塊錢回收來的舊家電進行拆解后，將舊的零部件掃掃灰，用新的包裝袋密封后就可以當新的賣了。按照回收價的比例，一個舊彩電的電路集成塊也就1塊錢，但是充當新的賣就可以賣到200元。而所謂"偷梁換柱"，就是在維修時偷偷把客戶電器上價格昂貴、質(zhì)量很好、沒有損壞的零件換下來，換上廉價的或從舊電器上拆下來的零件，不知情的消費者只能被蒙在鼓里。</span> 電源插座比較好不要放在桌面上，而是安裝在工作桌對面的墻上或直立在木板上。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="蘭州技術好的家電維修歡迎咨詢,家電維修"

style="font-size:16px;">當壁掛爐的使用超過8年、維修頻率較高或維修金額較大時，建議客戶更換新的壁掛爐。壁掛爐使用過程中的問題原因分析如果用戶購買的是小品牌壁掛爐，使用上頻繁出現(xiàn)問題，我們就建議客戶更換成品質(zhì)和售后都有更保障的大品牌壁掛爐產(chǎn)品。目前鍋爐的“零整比”過大——主要部件的更換費用高。更換主要配件時再重復維修，意義已經(jīng)不大了。壁掛爐如果使用5年以上且維修費用超過2000元，就可以考慮換新的了。如果壁掛爐是否要更換還取決于日常運行中燃氣的消耗情況——鍋爐越老，熱效率越低，燃氣運行費用越高。如果使用年限達到8年，采暖和洗浴</span><span style="font-size:16px;">能正常使用，但運行費用過高時，也應考慮更換壁掛爐了，更換時建議選購熱效率和環(huán)保指標更高的冷凝式壁掛爐。</span> 如果烘烤到受損元件時，故障現(xiàn)象就會立即被檢測人員發(fā)現(xiàn)，就可以立即判斷是該元件熱穩(wěn)定性不良引起的故障。蘭州技術好的家電維修歡迎咨詢</p><p

style="font-size:16px;">維修中經(jīng)常用到硅橡膠、絕緣膠、密封膠、導熱膠等，你知道他們的特點嗎？部分維修人員，把704膠當成導熱膠來用，甚至有人使用AB膠或502膠粘貼散熱片，導熱散熱效果很差，雖然不至于出什么大問題，但是只能說你不懂各種膠的使用方法，不建議這樣用。703膠：.......................耐冷水性好，耐溫稍低，粘結力好，光照后易發(fā)黃。1、水下儀器防潮密封，2、海底電纜灌封，3、小型電機磁瓦粘結，4、高壓包灌封前表涂，5、汽車底盤。6、冷凍冷藏設備，7、塑料紐扣粘結。常見在家電中固定中周、電位器等可調(diào)部位。704膠：耐高溫好，不耐水泡，粘牢度小，易折修，固化后不發(fā)黃。電加熱器、儀表儀器、分析電極、電熱插頭。在家電線路中固定導線、電容等高壓硅脂：不固化，適用于電子元器件的高壓部位絕緣滅弧，防潮，防銹。適用彩色電視機高壓帽的滅弧，密封防潮。防止放電打火。還適用于潤滑，阻尼等場合。本品呈半透明狀態(tài)，無毒，無氣味，無腐蝕，無刺激，不固化，不揮發(fā)。</span>
