高低溫試驗箱常見故(gu)(gu)障(zhang)(zhang)及排(pai)除方(fang)(fang)法,常見的(de)(de)(de)故(gu)(gu)障(zhang)(zhang)及排(pai)除方(fang)(fang)法,一(yi)(yi)(yi)般來說,出現故(gu)(gu)障(zhang)(zhang)是多(duo)方(fang)(fang)面(mian)的(de)(de)(de),有(you)人為(wei)因素,也(ye)有(you)環(huan)(huan)境因素等,如(ru)電壓(ya)過(guo)高,超出額定范圍(wei)就(jiu)會使(shi)一(yi)(yi)(yi)些電器(qi)部(bu)件損壞。簡(jian)單介紹(shao)有(you)在電器(qi)控(kong)(kong)制(zhi)(zhi)系(xi)統(tong)方(fang)(fang)面(mian),主要(yao)有(you)儀表、風(feng)(feng)機等。在高溫(wen)(wen)試(shi)(shi)(shi)驗(yan)中,如(ru)溫(wen)(wen)度(du)(du)(du)變化(hua)達(da)不(bu)(bu)到(dao)試(shi)(shi)(shi)驗(yan)溫(wen)(wen)度(du)(du)(du)值時(shi),可以(yi)檢查電器(qi)系(xi)統(tong),逐一(yi)(yi)(yi)排(pai)除故(gu)(gu)障(zhang)(zhang)。如(ru)溫(wen)(wen)度(du)(du)(du)升得很慢(man),就(jiu)要(yao)查看(kan)風(feng)(feng)循環(huan)(huan)系(xi)統(tong),檢查風(feng)(feng)道循環(huan)(huan)的(de)(de)(de)電機運(yun)(yun)轉(zhuan)是否(fou)正常。如(ru)果溫(wen)(wen)度(du)(du)(du)直接上(shang)升,過(guo)溫(wen)(wen)保護,那么(me),控(kong)(kong)制(zhi)(zhi)器(qi)出故(gu)(gu)障(zhang)(zhang),須更換控(kong)(kong)制(zhi)(zhi)儀表低(di)溫(wen)(wen)達(da)不(bu)(bu)到(dao)試(shi)(shi)(shi)驗(yan)的(de)(de)(de)指標,那你就(jiu)要(yao)觀(guan)察溫(wen)(wen)度(du)(du)(du)的(de)(de)(de)變化(hua),是溫(wen)(wen)度(du)(du)(du)降的(de)(de)(de)很慢(man),還是溫(wen)(wen)度(du)(du)(du)到(dao)一(yi)(yi)(yi)定值后溫(wen)(wen)度(du)(du)(du)有(you)回升的(de)(de)(de)趨勢,前者就(jiu)要(yao)檢查一(yi)(yi)(yi)下,做(zuo)低(di)溫(wen)(wen)試(shi)(shi)(shi)驗(yan)前是否(fou)將工作(zuo)室(shi)(shi)烘(hong)干,使(shi)工作(zuo)室(shi)(shi)保持干燥后再(zai)將試(shi)(shi)(shi)驗(yan)樣(yang)品放(fang)入工作(zuo)室(shi)(shi)內再(zai)做(zuo)試(shi)(shi)(shi)驗(yan),工作(zuo)室(shi)(shi)內的(de)(de)(de)試(shi)(shi)(shi)驗(yan)樣(yang)品是否(fou)放(fang)置的(de)(de)(de)過(guo)多(duo),使(shi)工作(zuo)室(shi)(shi)內的(de)(de)(de)風(feng)(feng)不(bu)(bu)能充分循環(huan)(huan),在排(pai)除上(shang)述原因后,就(jiu)要(yao)考慮是否(fou)是制(zhi)(zhi)冷系(xi)統(tong)中的(de)(de)(de)故(gu)(gu)障(zhang)(zhang)了,這(zhe)樣(yang)就(jiu)要(yao)請廠家(jia)的(de)(de)(de)專業(ye)人員進行檢修為(wei)了試(shi)(shi)(shi)驗(yan)箱的(de)(de)(de)能正常長期使(shi)用,在對設(she)備的(de)(de)(de)操作(zuo)過(guo)程中,我們都應嚴(yan)格(ge)遵守相關指導(dao)說明書(shu)來操作(zuo),這(zhe)樣(yang)設(she)備的(de)(de)(de)運(yun)(yun)行周期才會更加長久,使(shi)用起來也(ye)更得心(xin)應手
