Remark
- The oil consumption on above sheet is for reference only. The machine can always adopt fluoride or mineral substance oil. Pump oil and lubricant oil will be matched before delivery.
- Above cooling water consumption data is tested with ambient temperature at 30℃, cooling water suction temperature at 20℃,and water pressure from 0.15MPa to 0.2MPa. Various working condition will cause different cooling water consumption.
