Fixed stroke machines are by 5, 7, etc., I know that the impeller diameter is divided by, 5 is 500mm, 7 for the 700mm, but the general drawings only pressure, power, etc., that is, there is no impeller diameter. How do you know the diameter of the impeller?Thank you. Please let me know!
The data of general fans are obtained by experiment.28 blades are impossible, 2900r/minIt is estimated that the power is about 7.5-11KW at 1000r/min
Such as: impeller diameter 450; length 200; blade width 80; blade number 28; calculation of the centrifugal fan motor power required.It is very complicated to know the shape of an impeller and to calculate the power at a given speed.
Fan impeller diameter: from the impeller to the outermost edge of a straight line to the outer edge of the spirit, another point, the measured value is the diameter of the impeller.
Fan designers need to know the diameter of the fan impeller because the impeller diameter is an important factor in determining fan performance. But as fans, users are more concerned with fan pressure and power. To knowThe diameter of the impeller, when you press the pressure, power selection fan model, and then check the product manual, you can know the diameter of the impeller and other fan parameters.
