Water pump impeller in the number and size of the blade, what is the impact on the speed?
I do filtration equipment, and I think the leaves are mostly aimed at submerged pumps, which affect more.The more the blade, the greater the power of the motor, the greater the pump flow and lift.
The more blades, the larger the size, the greater the power required by the motor, according to the water pump manual to select the corresponding power motor, motor speed is fixed.
The number of blades represents the number of series, such as 1 impeller can hit 10 tons per hour, 10 meters per head, then the 10 impeller is 10*10=100 meters of head, flow 10 tons unchanged, the larger the impeller, the higher the head. As for the speed of different series, with different power, no effect on speed
