恒溫水浴振蕩器常見故障及處理

1、故障現象：恒溫水浴(yu)振(zhen)蕩器加熱(re)正常，振(zhen)蕩無法工作。

解(jie)決方法：① 打開(kai)(kai)控制柜側(ce)板，接(jie)通電(dian)(dian)(dian)(dian)(dian)源，將溫控設定為(wei)0度(du)(du)（即不加熱狀態(tai)），打開(kai)(kai)振蕩開(kai)(kai)關，將速度(du)(du)調至最(zui)高；② 用(yong)(yong)(yong)萬用(yong)(yong)(yong)表（交(jiao)(jiao)流250檔）測(ce)量(liang)變(bian)(bian)壓(ya)(ya)器(qi)有(you)(you)(you)無220V電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)輸(shu)入(ru)，若無則(ze)開(kai)(kai)關壞，反之(zhi)，測(ce)量(liang)變(bian)(bian)壓(ya)(ya)器(qi)有(you)(you)(you)無12V電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)輸(shu)出(chu)（用(yong)(yong)(yong)交(jiao)(jiao)流50V檔），無則(ze)變(bian)(bian)壓(ya)(ya)器(qi)壞；③ 此時切勿輕易更(geng)換(huan)變(bian)(bian)壓(ya)(ya)器(qi)，該情(qing)況(kuang)多(duo)為(wei)線(xian)路板中整(zheng)流部分(fen)或電(dian)(dian)(dian)(dian)(dian)機出(chu)現(xian)短路故障（出(chu)現(xian)此種現(xian)象，變(bian)(bian)壓(ya)(ya)器(qi)外(wai)觀有(you)(you)(you)燒焦現(xian)象），在排(pai)除以(yi)上情(qing)況(kuang)，更(geng)換(huan)即可；④ 12V電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)正(zheng)常，檢(jian)查有(you)(you)(you)無直流12電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)（直流50V檔），沒有(you)(you)(you)則(ze)整(zheng)流橋(qiao)斷(duan)路，更(geng)換(huan)；⑤ 有(you)(you)(you)則(ze)檢(jian)查有(you)(you)(you)無電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)輸(shu)出(chu)至電(dian)(dian)(dian)(dian)(dian)機（5-8V左(zuo)右），有(you)(you)(you)則(ze)電(dian)(dian)(dian)(dian)(dian)機壞或由于(yu)儀器(qi)長時間沒有(you)(you)(you)使用(yong)(yong)(yong)，機械部分(fen)銹(xiu)死，沒有(you)(you)(you)則(ze)控制板中大功率管(guan)壞。

2、故障現象：加熱正常，振蕩速度(du)變慢。

解決方法：打開控制柜側板(ban)(ban)，接通(tong)電源，將(jiang)溫(wen)控設定為0度（即不(bu)加熱狀態），打開振(zhen)蕩開關，將(jiang)速度調至最高，找到速度控制板(ban)(ban)上(shang)的兩個(ge)可調電阻，逆時針調整右邊(bian)的即可解決。

3、故障現象：恒溫水浴振蕩(dang)器不加熱，振蕩(dang)正常(chang)。

1）顯示正常(chang)，設(she)(she)定正常(chang)，無法(fa)加熱(re)(re)。該故(gu)障解決(jue)方法(fa)：接通電(dian)(dian)源(yuan)，打開電(dian)(dian)源(yuan)開關(guan)，調整(zheng)設(she)(she)定溫(wen)(wen)(wen)度高于實際測量溫(wen)(wen)(wen)度，檢(jian)查溫(wen)(wen)(wen)控(kong)(kong)儀(yi)有(you)無輸(shu)出指示，有(you)則(ze)測量加熱(re)(re)管是否(fou)有(you)電(dian)(dian)壓輸(shu)入，有(you)則(ze)加熱(re)(re)管壞(huai)，更換即可(ke)，沒有(you)電(dian)(dian)壓輸(shu)入加熱(re)(re)管，多(duo)為繼電(dian)(dian)器發生故(gu)障。若溫(wen)(wen)(wen)控(kong)(kong)儀(yi)沒有(you)電(dian)(dian)壓輸(shu)出指示，建議更換溫(wen)(wen)(wen)控(kong)(kong)儀(yi)。

2）溫控儀顯示LLL或(huo)999（根據廠(chang)家不同，參數有所不同）該故障為溫度(du)傳感(gan)器(qi)斷路(lu)或(huo)短路(lu)，更換傳感(gan)器(qi)即可。

3）溫度不受(shou)控制繼電器壞或傳感器受(shou)潮。
