Centrifugal fan installed fan impeller diameter (2000mm) (1200mm) (1600mm) (800mm) (600mm) () (400mm), which corresponds to the power of the fan. Be familiar with ventilators. Probably just fine.
You asked too general. In terms of 4-73:1600mm can match 18575 45KW1200mm can match 1321603715 18.5kw800mm can match 18.5303711 55kW600mm400mm
According to the similarity principle, a size proportion is calculated, and the size of the new air blower is directly generated according to the principle that the model is proportional to the corresponding size and the angle is equal.
If there is no extensive design experience, it is not recommended to carry out the calculation design. You can calculate the specific speed of the fan according to the air volume, pressure and rotation speed, and then find a fan model with the same specific speed,
Fan design is more complex, the impeller diameter, width and speed, not only you need the amount of air and pressure related, but also with the impeller you used in the form. The parameters of axial flow impeller, multi blade impeller, forward impeller and backward impeller are very different
