[恒溫恒濕試驗箱]為(wei)什么恒(heng)溫恒(heng)濕試(shi)驗箱溫度達不到設定值？

　　恒溫(wen)恒濕試驗(yan)箱在(zai)運用一段時間后常常會發現溫(wen)度達不到(dao)設(she)(she)定(ding)值，那(nei)么(me)究竟是什么(me)原(yuan)因致使溫(wen)度達不到(dao)設(she)(she)定(ding)值呢(ni)?

　　一、最常見(jian)的因為(wei)運用時(shi)代過(guo)久，缺(que)乏(fa)保(bao)養，致使恒(heng)溫恒(heng)濕(shi)試驗(yan)箱不(bu)(bu)制(zhi)冷(leng)(leng)(leng)，首要調查(cha)制(zhi)冷(leng)(leng)(leng)壓(ya)縮(suo)機(ji)(ji)(ji)在實(shi)驗(yan)箱運轉(zhuan)過(guo)程中是不(bu)(bu)是能夠(gou)發(fa)(fa)動(dong)，壓(ya)縮(suo)機(ji)(ji)(ji)在環境實(shi)驗(yan)設備運轉(zhuan)過(guo)程中都能夠(gou)發(fa)(fa)動(dong)，說(shuo)明從主電源(yuan)到各(ge)壓(ya)縮(suo)機(ji)(ji)(ji)的電器線路(lu)正常，。其次若恒(heng)溫恒(heng)濕(shi)試驗(yan)箱電氣系(xi)統沒有問題，持續檢查(cha)制(zhi)冷(leng)(leng)(leng)系(xi)統。首要檢查(cha)兩組(zu)制(zhi)冷(leng)(leng)(leng)機(ji)(ji)(ji)組(zu)的低(di)溫(R23)級壓(ya)縮(suo)機(ji)(ji)(ji)的排氣和(he)吸(xi)(xi)氣壓(ya)力都較正常值偏低(di)，并且吸(xi)(xi)氣壓(ya)力呈抽(chou)暇狀(zhuang)態，說(shuo)明主制(zhi)冷(leng)(leng)(leng)機(ji)(ji)(ji)組(zu)的制(zhi)冷(leng)(leng)(leng)劑(ji)(ji)量缺(que)少。最終用手摸主機(ji)(ji)(ji)組(zu)R23壓(ya)縮(suo)機(ji)(ji)(ji)的排氣和(he)吸(xi)(xi)氣管路(lu)，發(fa)(fa)現排氣管路(lu)的溫度不(bu)(bu)高，吸(xi)(xi)氣管路(lu)的溫度也不(bu)(bu)低(di)(未結(jie)霜(shuang))，這也說(shuo)明晰主機(ji)(ji)(ji)組(zu)的R23制(zhi)冷(leng)(leng)(leng)劑(ji)(ji)缺(que)少。

　　二、假如不(bu)是(shi)年久(jiu)失修的問題(ti)那么先要調查溫(wen)(wen)度的改變，是(shi)溫(wen)(wen)度降的很慢，還是(shi)溫(wen)(wen)度到一定值后(hou)溫(wen)(wen)度有上(shang)(shang)升的趨(qu)勢，前者就(jiu)要檢(jian)查一下，做(zuo)低溫(wen)(wen)實(shi)驗前是(shi)不(bu)是(shi)將作業室(shi)烘干，使作業室(shi)堅持枯燥(zao)后(hou)再將實(shi)驗樣(yang)(yang)品(pin)放入作業室(shi)內(nei)(nei)做(zuo)實(shi)驗，作業室(shi)內(nei)(nei)的實(shi)驗樣(yang)(yang)品(pin)是(shi)不(bu)是(shi)放置的過多，使作業室(shi)內(nei)(nei)的風不(bu)能充沛循環，在掃除上(shang)(shang)述原因后(hou)，就(jiu)要考慮是(shi)不(bu)是(shi)是(shi)制冷系統(tong)中的故障(zhang)了，這樣(yang)(yang)就(jiu)要請咱們的專業技術人員進行(xing)維修。

　　三、能夠檢查(cha)電(dian)器系統，逐(zhu)個掃除故(gu)障。如(ru)溫度(du)升得很慢(man)，就(jiu)要檢查(cha)風(feng)循環(huan)(huan)系統，看一下(xia)風(feng)循環(huan)(huan)的(de)調理擋板是(shi)(shi)(shi)不是(shi)(shi)(shi)敞開正常(chang)，反之，就(jiu)檢查(cha)風(feng)循環(huan)(huan)的(de)電(dian)機運轉(zhuan)是(shi)(shi)(shi)不是(shi)(shi)(shi)正常(chang)。如(ru)溫度(du)過(guo)沖兇猛(meng)那么就(jiu)需要整定PID的(de)設置參(can)數。假如(ru)溫度(du)直接上升，過(guo)溫維護，那么，操控(kong)器出故(gu)障，須替換操控(kong)儀(yi)。
