[恒溫恒濕試驗箱]恒溫恒濕試驗箱不制冷的根本原因及(ji)該怎么做？

　　恒(heng)溫恒(heng)濕試(shi)驗(yan)箱用于檢測材料在(zai)各(ge)種環境下(xia)性(xing)能的設備及試(shi)驗(yan)各(ge)種材料耐(nai)熱、耐(nai)寒、耐(nai)干、耐(nai)濕性(xing)能。

　　由于使用年代過久，缺發保養，導致(zhi)恒溫(wen)恒濕(shi)試(shi)驗箱(xiang)不制冷，遇到這種情況，我(wo)們應該做如下(xia)行動：

　　1.由于恒(heng)溫(wen)恒(heng)濕試驗箱(xiang)是溫(wen)度保持(chi)不住，觀察制冷壓(ya)縮機在(zai)試驗箱(xiang)運行過程中是否能(neng)夠啟(qi)動?壓(ya)縮機在(zai)環境試驗設備運行過程中都能(neng)夠啟(qi)動，說明從主電(dian)源到各壓(ya)縮機的電(dian)器(qi)線路正常，電(dian)器(qi)系統方(fang)面也沒有問題。

　　2、若恒溫(wen)恒濕試驗箱電氣(qi)(qi)系統沒有問題，繼(ji)續檢(jian)查制(zhi)冷(leng)(leng)(leng)系統。首先檢(jian)查兩組(zu)制(zhi)冷(leng)(leng)(leng)機組(zu)的低溫(wen)(R23)級壓(ya)縮機的排氣(qi)(qi)和吸(xi)氣(qi)(qi)壓(ya)力都較正常值偏低，而(er)且吸(xi)氣(qi)(qi)壓(ya)力呈抽空狀(zhuang)態，說(shuo)明主制(zhi)冷(leng)(leng)(leng)機組(zu)的制(zhi)冷(leng)(leng)(leng)劑量(liang)不足。

　　3、用(yong)手摸主(zhu)機(ji)組R23壓縮機(ji)的(de)排氣和吸氣管(guan)(guan)路，發現排氣管(guan)(guan)路的(de)溫(wen)度不高，吸氣管(guan)(guan)路的(de)溫(wen)度也不低(未結霜)，這也說明了主(zhu)機(ji)組的(de)R23制冷劑(ji)缺乏。
