恒溫恒濕試驗箱

時間：2019-01-18 08:42:40 點擊：次

恒溫(wen)恒濕(shi)試(shi)(shi)驗箱(xiang)：主要(yao)是用于做(zuo)高(gao)溫(wen)，低溫(wen)，濕(shi)度(du)試(shi)(shi)驗，測試(shi)(shi)電(dian)(dian)子電(dian)(dian)工(gong)(gong)，LED光電(dian)(dian)，化工(gong)(gong)，塑膠等產(chan)品的可靠性能(neng)，提高(gao)產(chan)品質(zhi)量。但是在(zai)運(yun)(yun)行(xing)(xing)過(guo)程中(zhong)，如果遇(yu)到恒溫(wen)恒濕(shi)試(shi)(shi)驗箱(xiang)溫(wen)度(du)達不到溫(wen)度(du)指標、低溫(wen)降溫(wen)慢、濕(shi)度(du)不能(neng)按照(zhao)預定運(yun)(yun)行(xing)(xing)三大(da)故障，我司結合(he)多年研發生(sheng)產(chan)實踐經(jing)驗，對此作出以下詳細(xi)分析(xi)，以供恒溫(wen)恒濕(shi)試(shi)(shi)驗箱(xiang)用戶參考借鑒(jian)。希(xi)望(wang)能(neng)有效幫助(zhu)大(da)家維護保養！
故障一：當恒溫恒濕試驗箱低溫達不到試驗的指標改如何解決？
恒(heng)(heng)(heng)溫(wen)(wen)(wen)(wen)恒(heng)(heng)(heng)濕(shi)試(shi)驗(yan)(yan)箱(xiang)低(di)溫(wen)(wen)(wen)(wen)達不(bu)到指標，降溫(wen)(wen)(wen)(wen)很(hen)慢(man)(man)那你就要(yao)觀察溫(wen)(wen)(wen)(wen)度(du)(du)的(de)(de)變化，是(shi)(shi)(shi)溫(wen)(wen)(wen)(wen)度(du)(du)降的(de)(de)很(hen)慢(man)(man)，還是(shi)(shi)(shi)溫(wen)(wen)(wen)(wen)度(du)(du)到一定(ding)值后(hou)(hou)溫(wen)(wen)(wen)(wen)度(du)(du)有回升的(de)(de)趨勢，前者就要(yao)檢(jian)查一下，做(zuo)低(di)溫(wen)(wen)(wen)(wen)試(shi)驗(yan)(yan)前是(shi)(shi)(shi)否將(jiang)工作(zuo)室(shi)烘(hong)干，使工作(zuo)室(shi)保持干燥后(hou)(hou)再將(jiang)試(shi)驗(yan)(yan)樣品放入工作(zuo)室(shi)內(nei)再做(zuo)試(shi)驗(yan)(yan)，工作(zuo)室(shi)內(nei)的(de)(de)試(shi)驗(yan)(yan)樣品是(shi)(shi)(shi)否放置的(de)(de)過多，使工作(zuo)室(shi)內(nei)的(de)(de)風不(bu)能充(chong)分循(xun)環，在(zai)排除上述原因后(hou)(hou)，就要(yao)考慮是(shi)(shi)(shi)否是(shi)(shi)(shi)制(zhi)冷系統(tong)中(zhong)的(de)(de)故(gu)障了，這樣就要(yao)請廠家(jia)的(de)(de)專(zhuan)業人(ren)員(yuan)進行檢(jian)修。后(hou)(hou)者的(de)(de)現象是(shi)(shi)(shi)恒(heng)(heng)(heng)溫(wen)(wen)(wen)(wen)恒(heng)(heng)(heng)濕(shi)試(shi)驗(yan)(yan)箱(xiang)設備的(de)(de)使用(yong)環境(jing)(jing)不(bu)好所致，設備放置的(de)(de)環境(jing)(jing)溫(wen)(wen)(wen)(wen)度(du)(du)，放置的(de)(de)位置(箱(xiang)體后(hou)(hou)與(yu)墻(qiang)的(de)(de)距離)要(yao)滿足要(yao)求(在(zai)設備操作(zuo)使用(yong)說明中(zhong)都(dou)有規定(ding))。
故障二：恒溫恒濕試驗箱在運行過程中，溫度變化達不到試驗溫度值，如何解決?
在高溫(wen)(wen)(wen)試(shi)(shi)驗(yan)中，如溫(wen)(wen)(wen)度變化達(da)不到試(shi)(shi)驗(yan)溫(wen)(wen)(wen)度值(zhi)時，可以檢查電(dian)器系(xi)統，逐一排除(chu)故障。如恒(heng)溫(wen)(wen)(wen)恒(heng)濕試(shi)(shi)驗(yan)箱(xiang)溫(wen)(wen)(wen)度升得很慢，就(jiu)要查看風循(xun)環系(xi)統，看一下風循(xun)環的(de)(de)調節擋板是否開(kai)啟正常，反之，就(jiu)檢查風循(xun)環的(de)(de)電(dian)機運轉是否正常。如溫(wen)(wen)(wen)度過(guo)沖(chong)厲害(hai)那么就(jiu)需要整定(ding)PID的(de)(de)設置參數。如果溫(wen)(wen)(wen)度直接上升，過(guo)溫(wen)(wen)(wen)保(bao)護，那么控制(zhi)器出故障，須更換(huan)控制(zhi)儀表(biao)。
故障三：恒溫恒濕試驗箱在濕熱試驗過程中，濕度達不到指定要求，是哪里出現問題?
恒(heng)(heng)溫恒(heng)(heng)濕(shi)試(shi)驗(yan)箱在做(zuo)濕(shi)熱(re)試(shi)驗(yan)中，出(chu)現實際濕(shi)度(du)會達到(dao)100%或者實際濕(shi)度(du)與目標濕(shi)度(du)相(xiang)差很大，數值低得很多(duo)，前者的(de)(de)(de)現象(xiang)：可能是(shi)(shi)(shi)(shi)濕(shi)球傳感(gan)(gan)器(qi)(qi)上(shang)的(de)(de)(de)紗布(bu)(bu)干燥引起，那(nei)(nei)就要(yao)檢查(cha)濕(shi)球傳感(gan)(gan)器(qi)(qi)的(de)(de)(de)水(shui)(shui)(shui)(shui)槽中是(shi)(shi)(shi)(shi)否(fou)(fou)缺(que)水(shui)(shui)(shui)(shui)，水(shui)(shui)(shui)(shui)槽中的(de)(de)(de)水(shui)(shui)(shui)(shui)位(wei)(wei)是(shi)(shi)(shi)(shi)由一(yi)水(shui)(shui)(shui)(shui)位(wei)(wei)控(kong)(kong)(kong)制(zhi)器(qi)(qi)自動控(kong)(kong)(kong)制(zhi)的(de)(de)(de)，查(cha)水(shui)(shui)(shui)(shui)位(wei)(wei)控(kong)(kong)(kong)制(zhi)器(qi)(qi)供(gong)(gong)水(shui)(shui)(shui)(shui)系(xi)(xi)統(tong)(tong)(tong)是(shi)(shi)(shi)(shi)否(fou)(fou)供(gong)(gong)水(shui)(shui)(shui)(shui)正(zheng)(zheng)(zheng)常，水(shui)(shui)(shui)(shui)位(wei)(wei)控(kong)(kong)(kong)制(zhi)器(qi)(qi)工(gong)作是(shi)(shi)(shi)(shi)否(fou)(fou)正(zheng)(zheng)(zheng)常。另一(yi)種可能就是(shi)(shi)(shi)(shi)濕(shi)球紗布(bu)(bu)因(yin)使用時間長，或供(gong)(gong)水(shui)(shui)(shui)(shui)水(shui)(shui)(shui)(shui)質純凈度(du)的(de)(de)(de)原因(yin)，會使紗布(bu)(bu)變硬，使紗布(bu)(bu)無法吸收水(shui)(shui)(shui)(shui)份(fen)而(er)干燥，只要(yao)更(geng)換或清洗紗布(bu)(bu)即可排除以(yi)上(shang)現象(xiang)。后者的(de)(de)(de)現象(xiang)主要(yao)是(shi)(shi)(shi)(shi)恒(heng)(heng)溫恒(heng)(heng)濕(shi)試(shi)驗(yan)箱的(de)(de)(de)加(jia)濕(shi)系(xi)(xi)統(tong)(tong)(tong)不工(gong)作，查(cha)看加(jia)濕(shi)系(xi)(xi)統(tong)(tong)(tong)的(de)(de)(de)供(gong)(gong)水(shui)(shui)(shui)(shui)系(xi)(xi)統(tong)(tong)(tong)，供(gong)(gong)水(shui)(shui)(shui)(shui)系(xi)(xi)統(tong)(tong)(tong)內(nei)是(shi)(shi)(shi)(shi)否(fou)(fou)有(you)一(yi)定(ding)的(de)(de)(de)水(shui)(shui)(shui)(shui)量，控(kong)(kong)(kong)制(zhi)加(jia)濕(shi)鍋爐水(shui)(shui)(shui)(shui)位(wei)(wei)的(de)(de)(de)水(shui)(shui)(shui)(shui)位(wei)(wei)控(kong)(kong)(kong)制(zhi)是(shi)(shi)(shi)(shi)否(fou)(fou)正(zheng)(zheng)(zheng)常，加(jia)濕(shi)鍋爐內(nei)的(de)(de)(de)水(shui)(shui)(shui)(shui)位(wei)(wei)是(shi)(shi)(shi)(shi)否(fou)(fou)正(zheng)(zheng)(zheng)常。如以(yi)上(shang)一(yi)切都正(zheng)(zheng)(zheng)常，那(nei)(nei)就要(yao)檢查(cha)電器(qi)(qi)控(kong)(kong)(kong)制(zhi)系(xi)(xi)統(tong)(tong)(tong)，請專業維修人員進行檢修。
恒溫恒濕試驗箱，因為有使用時限，所(suo)以(yi)運(yun)行(xing)時間(jian)超長(chang)的(de)恒溫恒濕試驗箱，難(nan)免會出(chu)現一些各(ge)種各(ge)樣的(de)小故障，平時注意定期(qi)保(bao)養(yang)和維(wei)護，一般(ban)都可(ke)以(yi)大部分避免。如(ru)果遇到較大技(ji)術難(nan)題，可(ke)以(yi)及時聯(lian)系我司，尋(xun)求解決。
