小型(xing)恒溫恒濕箱(xiang)運(yun)行時出現故障異常怎(zen)么辦

        小型(xing)恒(heng)溫恒(heng)濕(shi)箱(xiang)(xiang)又稱(cheng)桌上(shang)型(xing)恒(heng)溫恒(heng)濕(shi)試(shi)驗箱(xiang)(xiang)或迷(mi)你型(xing)恒(heng)溫恒(heng)濕(shi)箱(xiang)(xiang)，除了使(shi)用(yong)(yong)(yong)人(ren)員正確的(de)按操(cao)作流程(cheng)操(cao)作外，還(huan)應(ying)該要對結(jie)構有所(suo)了解(jie)。小型(xing)恒(heng)溫恒(heng)濕(shi)試(shi)驗箱(xiang)(xiang)的(de)結(jie)構是由(you)風(feng)循(xun)環(huan)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)、制(zhi)冷系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)、加(jia)溫系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)及控(kong)濕(shi)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)所(suo)組(zu)成的(de)。而(er)這些(xie)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)的(de)存在直(zhi)接(jie)與(yu)試(shi)驗箱(xiang)(xiang)價格的(de)高低有著密(mi)切(qie)的(de)關(guan)系(xi)(xi)(xi)。風(feng)循(xun)環(huan)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)一(yi)般采(cai)(cai)(cai)(cai)用(yong)(yong)(yong)的(de)是可調(diao)節(jie)送風(feng)方向(xiang)的(de)結(jie)構，加(jia)濕(shi)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)有采(cai)(cai)(cai)(cai)用(yong)(yong)(yong)鍋爐(lu)加(jia)濕(shi)的(de)和(he)表(biao)面蒸發兩(liang)種(zhong)。降溫、去濕(shi)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)采(cai)(cai)(cai)(cai)用(yong)(yong)(yong)的(de)是空(kong)調(diao)工況制(zhi)冷結(jie)構。加(jia)熱(re)(re)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)采(cai)(cai)(cai)(cai)用(yong)(yong)(yong)的(de)是電(dian)熱(re)(re)鰭片(pian)加(jia)熱(re)(re)和(he)電(dian)爐(lu)絲(si)直(zhi)接(jie)加(jia)熱(re)(re)二種(zhong)結(jie)構，溫濕(shi)度(du)測試(shi)方法(fa)(fa)采(cai)(cai)(cai)(cai)用(yong)(yong)(yong)干濕(shi)球測試(shi)方法(fa)(fa)，也有用(yong)(yong)(yong)濕(shi)度(du)傳感器(qi)直(zhi)接(jie)測量方法(fa)(fa)。控(kong)制(zhi)和(he)顯示操(cao)作界面采(cai)(cai)(cai)(cai)用(yong)(yong)(yong)溫濕(shi)度(du)分(fen)開獨立和(he)溫濕(shi)度(du)組(zu)合控(kong)制(zhi)器(qi)等方式。

　　 KOWIN小型恒(heng)溫(wen)(wen)恒(heng)濕箱在做高(gao)溫(wen)(wen)試驗中，如果(guo)溫(wen)(wen)度變(bian)化達不到試驗溫(wen)(wen)度值時，可以(yi)檢查(cha)電(dian)(dian)器系統(tong)，逐(zhu)漸一排除(chu)故障(zhang)。如溫(wen)(wen)度升(sheng)得(de)很慢，那就(jiu)要查(cha)看風(feng)循(xun)(xun)環(huan)(huan)系統(tong)，看一下(xia)風(feng)循(xun)(xun)環(huan)(huan)的調(diao)節檔板是否開啟正(zheng)常，反之，就(jiu)檢查(cha)風(feng)循(xun)(xun)環(huan)(huan)的電(dian)(dian)機運轉是否正(zheng)常。如溫(wen)(wen)度過沖厲害那么就(jiu)需要整定(ding)PID的設置參數(shu)。如果(guo)溫(wen)(wen)度直接上升(sheng)，過溫(wen)(wen)保護(hu)，那么，控制器出故障(zhang)，須更換控制儀表(biao)。

　　  低溫(wen)達(da)不到(dao)(dao)試(shi)驗(yan)的(de)(de)(de)指標，那(nei)就要(yao)觀(guan)察(cha)溫(wen)度的(de)(de)(de)變化，是溫(wen)度降的(de)(de)(de)很慢，還是溫(wen)度到(dao)(dao)一定值后(hou)(hou)溫(wen)度有回升(sheng)的(de)(de)(de)趨(qu)勢，前(qian)者就要(yao)檢查一下，做低溫(wen)試(shi)驗(yan)前(qian)是否(fou)將工作(zuo)室烘干，使(shi)(shi)工作(zuo)室保持干燥后(hou)(hou)再將試(shi)驗(yan)樣(yang)品(pin)放入工作(zuo)室內(nei)(nei)(nei)再做試(shi)驗(yan)，工作(zuo)室內(nei)(nei)(nei)的(de)(de)(de)試(shi)驗(yan)樣(yang)品(pin)是否(fou)放置的(de)(de)(de)過多，使(shi)(shi)工作(zuo)室內(nei)(nei)(nei)的(de)(de)(de)風(feng)不能充分循環，在排除上述(shu)原因后(hou)(hou)，就要(yao)考慮是否(fou)是制冷系統中(zhong)的(de)(de)(de)故(gu)障了(le)，如果是這樣(yang)的(de)(de)(de)話那(nei)么就要(yao)請廠家(jia)專業人(ren)員進行檢修了(le)。
