※ 海信日立壓縮機401DHVM-64D1其他注意事項 Remarks:
1.制冷系統 The refrigeration system
1)潤滑油與冷媒的重量比(潤滑油/冷媒)應在0.4 以上;
The ratio of oil to the refrigerant (oil/refrigerant) should be higher than 0.4 in weight basis.
2)當系統中壓縮機存在液態冷媒回流情況時,應采用儲液罐等設計避免液態冷媒回流;
When the compressor in the system has the liquid refrigerant flooding back operation,the
accumulator is required.
3)向壓縮機充油或冷媒時,必須從排氣側進行;
Charge oil or refrigerant from the discharge pipe.
4)系統應設置高壓壓力開關,參考設定值為2.8±0.1MPa。
Using high pressure switch in the refrigeration system is required,we advise setting pressure
as follow: 2.8±0.1MPa,
2.壓縮機在去除吸、排氣接頭蓋后,請勿放置10 分鐘以上;
Installation shall be completed within 10 minutes after removing the caps of suction and discharge
tube.
3.請勿壓縮空氣;
Do not compress air.
4.在真空狀態下請勿通電;
Do not energize under vacuumed condition.
5.熱泵系統必須在壓縮機底部安裝油加熱器(40~80W,220V);
Crankcase heater is required if the refrigeration system is heat pump.
6.運轉時,各相間的電壓偏差應在額定電壓的3%以內;
Voltage (run):Voltage deviation each phase shall be within 3% of the rated voltage.
7.請勿反向旋轉;
Do not reverse rotate.
8.壓縮機的接地裝置應*與制冷器具的接地裝置連接;
The compressor’s ground should be connected with that of refrigeration system permanently and
firmly.
9.成箱壓縮機包裝件的疊放堆碼極限為2 箱,裝卸過程中嚴禁翻滾。
Pile limits 2 pallet.Tumbling is forbidden during handling.
