恒溫水浴振蕩器常見故障及處理

1、故(gu)障現象(xiang)：恒溫水(shui)浴(yu)振蕩(dang)器(qi)加(jia)熱(re)正常，振蕩(dang)無法工作。

解決方法：① 打開控制柜側板(ban)，接通電(dian)(dian)(dian)(dian)源，將溫控設定為0度（即不加熱狀態），打開振蕩開關，將速度調至(zhi)(zhi)最(zui)高(gao)；② 用萬用表(biao)（交流250檔(dang)）測(ce)量變(bian)壓(ya)(ya)(ya)(ya)器(qi)有(you)(you)(you)無(wu)(wu)220V電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)輸(shu)入，若無(wu)(wu)則開關壞(huai)，反(fan)之，測(ce)量變(bian)壓(ya)(ya)(ya)(ya)器(qi)有(you)(you)(you)無(wu)(wu)12V電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)輸(shu)出(chu)(chu)（用交流50V檔(dang)），無(wu)(wu)則變(bian)壓(ya)(ya)(ya)(ya)器(qi)壞(huai)；③ 此時切勿輕易更換(huan)變(bian)壓(ya)(ya)(ya)(ya)器(qi)，該(gai)情況(kuang)多(duo)為線路(lu)板(ban)中(zhong)整(zheng)流部分或電(dian)(dian)(dian)(dian)機(ji)出(chu)(chu)現(xian)短路(lu)故(gu)障(zhang)（出(chu)(chu)現(xian)此種現(xian)象，變(bian)壓(ya)(ya)(ya)(ya)器(qi)外觀(guan)有(you)(you)(you)燒焦現(xian)象），在排除以(yi)上情況(kuang)，更換(huan)即可；④ 12V電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)正常，檢(jian)查(cha)有(you)(you)(you)無(wu)(wu)直(zhi)(zhi)流12電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)（直(zhi)(zhi)流50V檔(dang)），沒(mei)(mei)有(you)(you)(you)則整(zheng)流橋斷(duan)路(lu)，更換(huan)；⑤ 有(you)(you)(you)則檢(jian)查(cha)有(you)(you)(you)無(wu)(wu)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)輸(shu)出(chu)(chu)至(zhi)(zhi)電(dian)(dian)(dian)(dian)機(ji)（5-8V左(zuo)右(you)），有(you)(you)(you)則電(dian)(dian)(dian)(dian)機(ji)壞(huai)或由于儀器(qi)長時間(jian)沒(mei)(mei)有(you)(you)(you)使(shi)用，機(ji)械部分銹死，沒(mei)(mei)有(you)(you)(you)則控制板(ban)中(zhong)大功率管(guan)壞(huai)。

2、故(gu)障(zhang)現(xian)象：加(jia)熱正常，振蕩速(su)度變(bian)慢。

解決方法：打(da)開控制柜側板，接通電(dian)源，將(jiang)溫控設(she)定為0度(du)(du)（即不加熱狀態），打(da)開振蕩(dang)開關，將(jiang)速度(du)(du)調(diao)至最高，找到(dao)速度(du)(du)控制板上的兩個可調(diao)電(dian)阻，逆時(shi)針(zhen)調(diao)整右邊的即可解決。

3、故障現象(xiang)：恒溫水浴(yu)振蕩器不加(jia)熱(re)，振蕩正常。

1）顯示(shi)正(zheng)常，設定正(zheng)常，無法(fa)加熱(re)。該故障解決方法(fa)：接通(tong)電(dian)(dian)(dian)源，打(da)開電(dian)(dian)(dian)源開關，調整設定溫(wen)度高于實際測量溫(wen)度，檢查溫(wen)控儀有(you)無輸(shu)出指示(shi)，有(you)則測量加熱(re)管是否(fou)有(you)電(dian)(dian)(dian)壓輸(shu)入，有(you)則加熱(re)管壞，更換即可，沒有(you)電(dian)(dian)(dian)壓輸(shu)入加熱(re)管，多為繼電(dian)(dian)(dian)器發生故障。若(ruo)溫(wen)控儀沒有(you)電(dian)(dian)(dian)壓輸(shu)出指示(shi)，建議更換溫(wen)控儀。

2）溫控(kong)儀顯示LLL或999（根據廠家不同，參數有所不同）該故障為溫度傳感器斷(duan)路或短路，更(geng)換傳感器即(ji)可。

3）溫度(du)不受控制(zhi)繼電器壞(huai)或(huo)傳感器受潮。
