I would like to ask whether it is feasible to change the drive mechanism of a single 4000 m3/h cooling tower fan from electric power to a water turbine Parameters: Water treatment capacity per tower: 4000 m3/h; diameter of the pipe in the upper tower: DN800; total height of the tower: 21.75 m; opening degree of the butterfly valve before the upper tower: 30–40%; rated flow rate of the water pump: 2200 m3/h; head: 48 meters; total number of pumps: 3; 2 pumps are in operation at any given time; power of the fan: 160 KW; rotation speed: 127; blade diameter: 9140; return pressure of the circulating water: 0.3 MPA; outlet pressure of the water pump: 0.64 MPA; opening degree of the outlet valve: 35–40%; rated power of the water pump: 450 KW; actual power at present: 420–430 KW. Question: Is it feasible to use a water turbine? Can it meet the cooling temperature requirements in summer? Does it increase the power consumption of the water pump after installation? Is it energy-efficient? How much can be saved? Thank you!

It’s recommended not to make any changes; our company has tried to make changes before but lacked the motivation, and in the end it reverted back to having that motivation. Tragic.
This parameter poses a risk; it is recommended not to change it. I used to do this before; be careful that the fan speed doesn’t drop below the required level.
What is the current of the fan that is currently operating at a distance? Based on the backwater pressure, it can be determined whether a change is possible. Wang Lihui from Dezhou Benuo Fan Company – contact him at 18615342179; technical discussions are welcome at any time
