小(xiao)型恒(heng)溫恒(heng)濕箱運行時出現故障異常怎(zen)么辦

        小(xiao)型恒溫恒濕(shi)(shi)(shi)箱(xiang)(xiang)又稱桌上(shang)型恒溫恒濕(shi)(shi)(shi)試驗箱(xiang)(xiang)或迷你型恒溫恒濕(shi)(shi)(shi)箱(xiang)(xiang)，除了使用(yong)(yong)人(ren)員正確(que)的(de)按操作(zuo)(zuo)流(liu)程操作(zuo)(zuo)外，還應(ying)該要(yao)對結(jie)(jie)構(gou)有(you)(you)所了解(jie)。小(xiao)型恒溫恒濕(shi)(shi)(shi)試驗箱(xiang)(xiang)的(de)結(jie)(jie)構(gou)是由風(feng)循(xun)環(huan)系(xi)(xi)統、制(zhi)冷系(xi)(xi)統、加(jia)(jia)(jia)溫系(xi)(xi)統及控(kong)濕(shi)(shi)(shi)系(xi)(xi)統所組成(cheng)的(de)。而這些系(xi)(xi)統的(de)存在直接(jie)與試驗箱(xiang)(xiang)價格(ge)的(de)高低有(you)(you)著密切的(de)關系(xi)(xi)。風(feng)循(xun)環(huan)系(xi)(xi)統一般采(cai)用(yong)(yong)的(de)是可調節送風(feng)方(fang)(fang)向(xiang)的(de)結(jie)(jie)構(gou)，加(jia)(jia)(jia)濕(shi)(shi)(shi)系(xi)(xi)統有(you)(you)采(cai)用(yong)(yong)鍋(guo)爐(lu)加(jia)(jia)(jia)濕(shi)(shi)(shi)的(de)和(he)表面(mian)蒸(zheng)發兩種。降溫、去濕(shi)(shi)(shi)系(xi)(xi)統采(cai)用(yong)(yong)的(de)是空調工況制(zhi)冷結(jie)(jie)構(gou)。加(jia)(jia)(jia)熱(re)系(xi)(xi)統采(cai)用(yong)(yong)的(de)是電熱(re)鰭片加(jia)(jia)(jia)熱(re)和(he)電爐(lu)絲直接(jie)加(jia)(jia)(jia)熱(re)二種結(jie)(jie)構(gou)，溫濕(shi)(shi)(shi)度(du)測試方(fang)(fang)法采(cai)用(yong)(yong)干濕(shi)(shi)(shi)球測試方(fang)(fang)法，也有(you)(you)用(yong)(yong)濕(shi)(shi)(shi)度(du)傳感器直接(jie)測量方(fang)(fang)法。控(kong)制(zhi)和(he)顯示(shi)操作(zuo)(zuo)界面(mian)采(cai)用(yong)(yong)溫濕(shi)(shi)(shi)度(du)分開獨(du)立和(he)溫濕(shi)(shi)(shi)度(du)組合控(kong)制(zhi)器等方(fang)(fang)式(shi)。

　　 KOWIN小型恒(heng)溫(wen)(wen)(wen)(wen)恒(heng)濕(shi)箱在(zai)做高溫(wen)(wen)(wen)(wen)試(shi)驗中，如果溫(wen)(wen)(wen)(wen)度(du)變化達不到試(shi)驗溫(wen)(wen)(wen)(wen)度(du)值(zhi)時(shi)，可(ke)以(yi)檢查(cha)(cha)電器(qi)系統，逐漸(jian)一(yi)排除故障(zhang)。如溫(wen)(wen)(wen)(wen)度(du)升得很(hen)慢(man)，那(nei)(nei)就要查(cha)(cha)看(kan)風循(xun)環系統，看(kan)一(yi)下風循(xun)環的調節檔板是否開啟正常(chang)，反之(zhi)，就檢查(cha)(cha)風循(xun)環的電機運(yun)轉是否正常(chang)。如溫(wen)(wen)(wen)(wen)度(du)過沖厲害那(nei)(nei)么就需要整(zheng)定PID的設(she)置(zhi)參(can)數。如果溫(wen)(wen)(wen)(wen)度(du)直接上升，過溫(wen)(wen)(wen)(wen)保護，那(nei)(nei)么，控制(zhi)器(qi)出(chu)故障(zhang)，須更換控制(zhi)儀表。

　　  低溫達不到試(shi)驗的(de)指(zhi)標，那就(jiu)(jiu)要觀察(cha)溫度(du)的(de)變化，是(shi)溫度(du)降的(de)很(hen)慢，還是(shi)溫度(du)到一定值后(hou)溫度(du)有回升的(de)趨勢，前者就(jiu)(jiu)要檢查(cha)一下，做(zuo)低溫試(shi)驗前是(shi)否將(jiang)工(gong)作(zuo)室(shi)烘干，使(shi)工(gong)作(zuo)室(shi)保(bao)持干燥后(hou)再將(jiang)試(shi)驗樣(yang)(yang)品放入工(gong)作(zuo)室(shi)內(nei)再做(zuo)試(shi)驗，工(gong)作(zuo)室(shi)內(nei)的(de)試(shi)驗樣(yang)(yang)品是(shi)否放置的(de)過多，使(shi)工(gong)作(zuo)室(shi)內(nei)的(de)風不能充分循環，在(zai)排除上述(shu)原因后(hou)，就(jiu)(jiu)要考慮是(shi)否是(shi)制冷系(xi)統(tong)中的(de)故障了(le)，如果是(shi)這(zhe)樣(yang)(yang)的(de)話(hua)那么就(jiu)(jiu)要請廠家專業(ye)人(ren)員(yuan)進行檢修了(le)。
