高低溫測試儀或恒溫恒濕測試機不降溫的原因分析
高低(di)(di)(di)溫測(ce)(ce)(ce)試(shi)(shi)(shi)儀(yi)或恒(heng)溫恒(heng)濕測(ce)(ce)(ce)試(shi)(shi)(shi)機不降溫的(de)(de)(de)原(yuan)因分析首先觀察高低(di)(di)(di)溫測(ce)(ce)(ce)試(shi)(shi)(shi)儀(yi)制冷(leng)壓(ya)(ya)縮(suo)機在做低(di)(di)(di)溫運行(xing)過程中(zhong)(zhong)是否能夠啟動,如果(guo)高低(di)(di)(di)溫測(ce)(ce)(ce)試(shi)(shi)(shi)儀(yi)的(de)(de)(de)壓(ya)(ya)縮(suo)機在運行(xing)過程中(zhong)(zhong)都能夠啟動,說(shuo)明從主電源到各高低(di)(di)(di)溫測(ce)(ce)(ce)試(shi)(shi)(shi)儀(yi)壓(ya)(ya)縮(suo)機的(de)(de)(de)電器(qi)(qi)線路(lu)都正(zheng)常(chang),電器(qi)(qi)系統方面也就沒有問題(ti)。當高低(di)(di)(di)溫測(ce)(ce)(ce)試(shi)(shi)(shi)箱的(de)(de)(de)電氣(qi)系統都沒有問題(ti)時(shi),則(ze)繼續檢(jian)查制冷(leng)系統。首先檢(jian)查高低(di)(di)(di)溫測(ce)(ce)(ce)試(shi)(shi)(shi)箱的(de)(de)(de)兩組制冷(leng)壓(ya)(ya)縮(suo)機組,如果(guo)低(di)(di)(di)溫級壓(ya)(ya)縮(suo)機的(de)(de)(de)排氣(qi)和吸氣(qi)壓(ya)(ya)力都較正(zheng)常(chang)值偏低(di)(di)(di),而且(qie)吸氣(qi)壓(ya)(ya)力呈抽空(kong)狀態
