步入式溫控箱|步入式溫控試驗室常見故障排除
1.在高溫(wen)控制(zhi)試驗(yan)中(zhong)，如(ru)溫(wen)度(du)(du)(du)變化達(da)不到(dao)試驗(yan)溫(wen)度(du)(du)(du)值時(shi)，可以(yi)檢查電器(qi)(qi)系統，逐一排除(chu)故障。如(ru)溫(wen)度(du)(du)(du)升得很慢，就要查看風循環系統，看一下風循環的(de)調節擋板是否開(kai)啟正(zheng)常，反(fan)之，就檢查風循環的(de)電機運(yun)轉是否正(zheng)常。如(ru)溫(wen)度(du)(du)(du)過(guo)(guo)沖厲害那么就需要整定PID 的(de)設置參數。如(ru)果(guo)溫(wen)度(du)(du)(du)直接上(shang)升，過(guo)(guo)溫(wen)保護(hu)，那么，控制(zhi)器(qi)(qi)出故障，須更換(huan)控制(zhi)儀表。
2.低溫控制(zhi)達(da)不(bu)到(dao)試驗(yan)(yan)(yan)的(de)(de)(de)(de)指標，那你就(jiu)要觀(guan)察溫度(du)的(de)(de)(de)(de)變(bian)化(hua)，是(shi)(shi)(shi)溫度(du)降的(de)(de)(de)(de)很慢，還是(shi)(shi)(shi)溫度(du)到(dao)一定值后(hou)溫度(du)有(you)回(hui)升的(de)(de)(de)(de)趨勢，前(qian)者就(jiu)要檢(jian)查一下，做(zuo)低溫試驗(yan)(yan)(yan)前(qian)是(shi)(shi)(shi)否將工(gong)作室烘干，使(shi)(shi)工(gong)作室保持干燥(zao)后(hou)再將試驗(yan)(yan)(yan)樣品放入工(gong)作室內再做(zuo)試驗(yan)(yan)(yan)，工(gong)作室內的(de)(de)(de)(de)試驗(yan)(yan)(yan)樣品是(shi)(shi)(shi)否放置(zhi)(zhi)的(de)(de)(de)(de)過多(duo)，使(shi)(shi)工(gong)作室內的(de)(de)(de)(de)風不(bu)能充分循環(huan)，在排除上述原因(yin)后(hou)，就(jiu)要考慮是(shi)(shi)(shi)否是(shi)(shi)(shi)制(zhi)冷系統中的(de)(de)(de)(de)故障了(le)，這樣就(jiu)要請廠家的(de)(de)(de)(de)專業人員進(jin)行(xing)檢(jian)修。后(hou)者的(de)(de)(de)(de)現象是(shi)(shi)(shi)設備(bei)的(de)(de)(de)(de)使(shi)(shi)用(yong)環(huan)境不(bu)好所致(zhi)，設備(bei)放置(zhi)(zhi)的(de)(de)(de)(de)環(huan)境溫度(du)，放置(zhi)(zhi)的(de)(de)(de)(de)位置(zhi)(zhi)（箱體(ti)后(hou)與墻(qiang)的(de)(de)(de)(de)距離）要滿足要求（在設備(bei)操(cao)作使(shi)(shi)用(yong)說明(ming)中都有(you)規定）。
3.步(bu)(bu)入式溫控(kong)(kong)箱|步(bu)(bu)入式溫控(kong)(kong)試驗室在(zai)試驗運行(xing)過(guo)程中(zhong)(zhong)突然(ran)出現故(gu)障(zhang)時，控(kong)(kong)制儀表上(shang)出現對應(ying)的(de)故(gu)障(zhang)顯示(shi)提示(shi)并有聲訊報警提示(shi)。操作人員(yuan)可以對照設備的(de)操作使(shi)用中(zhong)(zhong)的(de)故(gu)障(zhang)排除一(yi)章中(zhong)(zhong)快速檢查(cha)出屬于哪一(yi)類(lei)故(gu)障(zhang)，即可請(qing)專(zhuan)業人員(yuan)快速排除故(gu)障(zhang)，以確保試驗的(de)正常(chang)進行(xing)。
