Are the centrifugal water pump and motor compatible?
Thread Content
Parameters of the company’s centrifugal pump: speed of 1450, flow rate of 400 m3/h, head of 38 meters, and an associated motor with a power of 37 KW. Is this acceptable? What is this thing added at the pump outlet, and what is its function?
Is it a slow-closing check valve?
Assuming a pump efficiency of 100%, the shaft power would also be over 41 KW. Do you think any pump can achieve such a level?
You’re using a hydraulic turbine; its effective power is 41 kilowatts, and the efficiency of the pump is over 110%.
I really don’t know what that thing exported is; the one below it is a check valve
Effective power Ne=QHγ/367=400*38*1000/367=41.4kW＞37KW; the motor is too small.
The motor is too small; based on an efficiency of 80% when pumping water, the shaft power remains at 52 kW
Thanks to everyone’s explanations, I understand that it’s due to the design; otherwise, several pumps would have exceeded their rated current! I have this question; it helps to get everyone’s confirmation on it. Thank you all!
That thing seems to be some kind of measuring instrument
