深圳/東莞/惠州/中山/珠海/佛山高低溫試驗箱維修，高低溫測試箱維修，高低溫箱維修，請東莞市科文試驗設備有限公司：////szyqk.cn

一、高低溫試驗設備.在高溫試驗中，如溫度變化達不到試驗溫度值時，可以檢查電器系統，逐一排除故障。如溫度升得很慢，就要查看風循環系統，看一下風循環的調節擋板是否開啟正常，反之，就檢查風循環的電機運轉是否正常。如溫度過沖厲害那么就需要整定PID的設置參數。如果溫度直接上升，過溫保護，那么，控制器出故障，須更換控制儀表。
　

二、.高低溫(wen)試驗(yan)箱在(zai)(zai)試驗(yan)運行過程(cheng)中(zhong)突(tu)然(ran)出現(xian)(xian)故障(zhang)(zhang)時，控制(zhi)儀表上出現(xian)(xian)對(dui)應的故障(zhang)(zhang)顯示(shi)提示(shi)并有(you)聲訊(xun)報警提示(shi)。操(cao)(cao)作(zuo)人員可以對(dui)照設(she)(she)備(bei)(bei)的操(cao)(cao)作(zuo)使(shi)用(yong)中(zhong)的故障(zhang)(zhang)排(pai)(pai)(pai)除一章中(zhong)快速(su)檢查出屬于(yu)哪(na)一類故障(zhang)(zhang)，即可請專業人員快速(su)排(pai)(pai)(pai)除故障(zhang)(zhang)，以確保(bao)試驗(yan)的正常進行。其它環(huan)境試驗(yan)設(she)(she)備(bei)(bei)在(zai)(zai)使(shi)用(yong)中(zhong)還(huan)會有(you)其它的現(xian)(xian)象，那就要具體現(xian)(xian)象，具體分析和排(pai)(pai)(pai)除。環(huan)境試驗(yan)設(she)(she)備(bei)(bei)還(huan)要定(ding)期(qi)進行維護保(bao)養(yang)，制(zhi)冷系統的冷凝器定(ding)期(qi)清理(li)，對(dui)于(yu)活動(dong)部(bu)件(jian)應按說明(ming)書加油潤滑(hua)，電(dian)器控制(zhi)系統定(ding)期(qi)維護檢查等等，這些(xie)工(gong)作(zuo)是*的。　

三、高低(di)溫測試(shi)箱低溫達不到試驗的指標，那你就要觀察溫度的變化，是溫度降的很慢，還是溫度到一定值后溫度有回升的趨勢，前者就要檢查一下，做低溫試驗前是否將工作室烘干，使工作室保持干燥后再將試驗樣品放入工作室內再做試驗，工作室內的試驗樣品是否放置的過多，使工作室內的風不能充分循環，在排除上述原因后，就要考慮是否是制冷系統中的故障了，這樣就要請廠家的專業人員進行檢修。后者的現象是設備的使用環境不好所致，設備放置的環境溫度，放置的位置（箱體后與墻的距離）要滿足要求（在設備操作使用說明中都有規定）。
　

四、高低(di)溫箱在做濕(shi)(shi)(shi)熱試驗中(zhong)(zhong)，出現實(shi)際濕(shi)(shi)(shi)度會達到100%或(huo)(huo)者(zhe)(zhe)實(shi)際濕(shi)(shi)(shi)度與目標濕(shi)(shi)(shi)度相差很大，數(shu)值(zhi)低(di)得很多，前(qian)者(zhe)(zhe)的(de)(de)現象(xiang)：可(ke)能是(shi)(shi)濕(shi)(shi)(shi)球(qiu)傳(chuan)感器(qi)上(shang)的(de)(de)紗布(bu)(bu)干(gan)燥引起，那(nei)就(jiu)要(yao)(yao)檢(jian)(jian)查(cha)(cha)濕(shi)(shi)(shi)球(qiu)傳(chuan)感器(qi)的(de)(de)水(shui)槽中(zhong)(zhong)是(shi)(shi)否(fou)(fou)(fou)缺水(shui)，水(shui)槽中(zhong)(zhong)的(de)(de)水(shui)位(wei)(wei)(wei)(wei)是(shi)(shi)由一水(shui)位(wei)(wei)(wei)(wei)控(kong)(kong)(kong)制(zhi)(zhi)器(qi)自動控(kong)(kong)(kong)制(zhi)(zhi)的(de)(de)，查(cha)(cha)水(shui)位(wei)(wei)(wei)(wei)控(kong)(kong)(kong)制(zhi)(zhi)器(qi)供水(shui)系統(tong)是(shi)(shi)否(fou)(fou)(fou)供水(shui)正(zheng)常，水(shui)位(wei)(wei)(wei)(wei)控(kong)(kong)(kong)制(zhi)(zhi)器(qi)工(gong)(gong)作(zuo)是(shi)(shi)否(fou)(fou)(fou)正(zheng)常。另一種(zhong)可(ke)能就(jiu)是(shi)(shi)濕(shi)(shi)(shi)球(qiu)紗布(bu)(bu)因(yin)(yin)使(shi)用時間長，或(huo)(huo)供水(shui)水(shui)質純凈度的(de)(de)原因(yin)(yin)，會使(shi)紗布(bu)(bu)變硬，使(shi)紗布(bu)(bu)無法吸(xi)收水(shui)份而干(gan)燥，只要(yao)(yao)更換或(huo)(huo)清洗紗布(bu)(bu)即可(ke)排除(chu)以上(shang)現象(xiang)。后者(zhe)(zhe)的(de)(de)現象(xiang)主要(yao)(yao)是(shi)(shi)加(jia)濕(shi)(shi)(shi)系統(tong)不工(gong)(gong)作(zuo)，查(cha)(cha)看加(jia)濕(shi)(shi)(shi)系統(tong)的(de)(de)供水(shui)系統(tong)，供水(shui)系統(tong)內是(shi)(shi)否(fou)(fou)(fou)有一定的(de)(de)水(shui)量(liang)，控(kong)(kong)(kong)制(zhi)(zhi)加(jia)濕(shi)(shi)(shi)鍋(guo)爐水(shui)位(wei)(wei)(wei)(wei)的(de)(de)水(shui)位(wei)(wei)(wei)(wei)控(kong)(kong)(kong)制(zhi)(zhi)是(shi)(shi)否(fou)(fou)(fou)正(zheng)常，加(jia)濕(shi)(shi)(shi)鍋(guo)爐內的(de)(de)水(shui)位(wei)(wei)(wei)(wei)是(shi)(shi)否(fou)(fou)(fou)正(zheng)常。如以上(shang)一切都正(zheng)常，那(nei)就(jiu)要(yao)(yao)檢(jian)(jian)查(cha)(cha)電器(qi)控(kong)(kong)(kong)制(zhi)(zhi)系統(tong)，這要(yao)(yao)請專(zhuan)業維(wei)修人員進行檢(jian)(jian)修。
