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：////xiaoneiwangcode.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(gao)低溫試驗(yan)(yan)(yan)箱在試驗(yan)(yan)(yan)運行過程中突(tu)然出現(xian)(xian)(xian)故(gu)障(zhang)時，控制儀表(biao)上出現(xian)(xian)(xian)對應(ying)的(de)故(gu)障(zhang)顯示(shi)(shi)提(ti)示(shi)(shi)并有聲訊報警(jing)提(ti)示(shi)(shi)。操作人(ren)員可以對照設備的(de)操作使(shi)用(yong)中的(de)故(gu)障(zhang)排(pai)除一(yi)章(zhang)中快(kuai)速檢(jian)查出屬于(yu)哪一(yi)類(lei)故(gu)障(zhang)，即可請專(zhuan)業(ye)人(ren)員快(kuai)速排(pai)除故(gu)障(zhang)，以確保(bao)試驗(yan)(yan)(yan)的(de)正常進(jin)行。其(qi)它環(huan)境(jing)試驗(yan)(yan)(yan)設備在使(shi)用(yong)中還會有其(qi)它的(de)現(xian)(xian)(xian)象(xiang)，那就要具(ju)(ju)體(ti)(ti)現(xian)(xian)(xian)象(xiang)，具(ju)(ju)體(ti)(ti)分析和排(pai)除。環(huan)境(jing)試驗(yan)(yan)(yan)設備還要定(ding)期(qi)進(jin)行維護保(bao)養，制冷系統(tong)的(de)冷凝(ning)器(qi)定(ding)期(qi)清理，對于(yu)活(huo)動部(bu)件(jian)應(ying)按說(shuo)明書加油(you)潤滑，電器(qi)控制系統(tong)定(ding)期(qi)維護檢(jian)查等等，這(zhe)些工作是*的(de)。　

三、高低溫測試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、高低溫箱在做濕(shi)(shi)(shi)熱試驗中(zhong)，出現(xian)實際濕(shi)(shi)(shi)度(du)會(hui)達到100%或者實際濕(shi)(shi)(shi)度(du)與目標濕(shi)(shi)(shi)度(du)相差很(hen)大，數值低得很(hen)多，前(qian)者的(de)(de)(de)現(xian)象(xiang)：可能(neng)是(shi)(shi)濕(shi)(shi)(shi)球(qiu)傳感器(qi)上(shang)的(de)(de)(de)紗布干燥(zao)(zao)引起，那(nei)就(jiu)要(yao)(yao)(yao)檢(jian)查(cha)(cha)濕(shi)(shi)(shi)球(qiu)傳感器(qi)的(de)(de)(de)水(shui)(shui)(shui)(shui)(shui)(shui)槽中(zhong)是(shi)(shi)否缺水(shui)(shui)(shui)(shui)(shui)(shui)，水(shui)(shui)(shui)(shui)(shui)(shui)槽中(zhong)的(de)(de)(de)水(shui)(shui)(shui)(shui)(shui)(shui)位是(shi)(shi)由(you)一水(shui)(shui)(shui)(shui)(shui)(shui)位控(kong)制(zhi)(zhi)(zhi)(zhi)器(qi)自動(dong)控(kong)制(zhi)(zhi)(zhi)(zhi)的(de)(de)(de)，查(cha)(cha)水(shui)(shui)(shui)(shui)(shui)(shui)位控(kong)制(zhi)(zhi)(zhi)(zhi)器(qi)供(gong)水(shui)(shui)(shui)(shui)(shui)(shui)系(xi)統是(shi)(shi)否供(gong)水(shui)(shui)(shui)(shui)(shui)(shui)正(zheng)(zheng)常(chang)(chang)，水(shui)(shui)(shui)(shui)(shui)(shui)位控(kong)制(zhi)(zhi)(zhi)(zhi)器(qi)工(gong)作(zuo)是(shi)(shi)否正(zheng)(zheng)常(chang)(chang)。另一種可能(neng)就(jiu)是(shi)(shi)濕(shi)(shi)(shi)球(qiu)紗布因(yin)使用時(shi)間(jian)長，或供(gong)水(shui)(shui)(shui)(shui)(shui)(shui)水(shui)(shui)(shui)(shui)(shui)(shui)質純凈(jing)度(du)的(de)(de)(de)原因(yin)，會(hui)使紗布變硬，使紗布無法吸收水(shui)(shui)(shui)(shui)(shui)(shui)份而(er)干燥(zao)(zao)，只要(yao)(yao)(yao)更換或清洗紗布即可排除(chu)以(yi)上(shang)現(xian)象(xiang)。后者的(de)(de)(de)現(xian)象(xiang)主(zhu)要(yao)(yao)(yao)是(shi)(shi)加(jia)濕(shi)(shi)(shi)系(xi)統不(bu)工(gong)作(zuo)，查(cha)(cha)看加(jia)濕(shi)(shi)(shi)系(xi)統的(de)(de)(de)供(gong)水(shui)(shui)(shui)(shui)(shui)(shui)系(xi)統，供(gong)水(shui)(shui)(shui)(shui)(shui)(shui)系(xi)統內(nei)是(shi)(shi)否有一定(ding)的(de)(de)(de)水(shui)(shui)(shui)(shui)(shui)(shui)量，控(kong)制(zhi)(zhi)(zhi)(zhi)加(jia)濕(shi)(shi)(shi)鍋(guo)(guo)爐水(shui)(shui)(shui)(shui)(shui)(shui)位的(de)(de)(de)水(shui)(shui)(shui)(shui)(shui)(shui)位控(kong)制(zhi)(zhi)(zhi)(zhi)是(shi)(shi)否正(zheng)(zheng)常(chang)(chang)，加(jia)濕(shi)(shi)(shi)鍋(guo)(guo)爐內(nei)的(de)(de)(de)水(shui)(shui)(shui)(shui)(shui)(shui)位是(shi)(shi)否正(zheng)(zheng)常(chang)(chang)。如以(yi)上(shang)一切(qie)都正(zheng)(zheng)常(chang)(chang)，那(nei)就(jiu)要(yao)(yao)(yao)檢(jian)查(cha)(cha)電(dian)器(qi)控(kong)制(zhi)(zhi)(zhi)(zhi)系(xi)統，這要(yao)(yao)(yao)請專業維修(xiu)人員(yuan)進(jin)行檢(jian)修(xiu)。
