高低溫試驗箱對冷卻水的要求

發布日期:2022-04-27 點擊率:91

  冷卻用水必須是潔凈自來水或循環水,有條件應做軟化處理,水溫小于28℃,進水水壓達到0.2~0.4MPa,管徑及水流量須達到設備所需要的要求,必須配備自動補水裝置(冰水機不需要),防止循環水蒸發損耗造成冷卻不良。
  為確保高低溫試驗箱冷卻效果正常,當觀察回水水壓明顯偏低,回水溫度變高時,請注意檢查Y型過濾器是否堵塞,如果堵塞將Y型過濾器的過濾芯拆下,有泥沙、樹葉等雜物在過濾網中,請清洗干凈,再原樣裝回去。
  當冷卻水塔外部環境低于0度時,且機器不運行時,必須將冷卻水塔內的水排掉,否則水管中的水結冰,將會凍裂水管,造成設備損壞。水塔電源建議受控于試驗箱,壓縮機啟動時,水塔才起動,從而達到節能的效果。
