I have a question regarding the calculation of energy efficiency for centrifugal pumps
Thread Content
Dear fellow sea enthusiasts, why can centrifugal pumps save 50%-80% in energy consumption when operating within the range shown in the diagram? How was it obtained, through calculation or experimentation? Thank you
Personally, I think this energy saving is relative. It is viewed from the perspective of the efficiency slope. In the 70-100 range, efficiency is relatively high; beyond this range, efficiency drops significantly, with lower flow rates and lower shaft power. When lifting 10 tons of water to the same height, the total electrical energy consumed varies depending on whether it is done at 70 units or 100 units. Personal opinion
