　　How do centrifugal fan manufacturers improve the centrifugal fan impeller?

　　When assembling the main motor, due to the small size of the fan, the external parts, inlet parts and suction container of the old fan are retained during the processing. For example, if there were 28 feathers before, and the centrifugal fan manufacturer completely welded each feather, the connecting part of the wheel cover and the plate, the thickness of each feather was increased to 3 mm, the thickness of the plate was 5 mm, and the thickness of the wheel assembly was increased to 4 mm. 32 wings are used to strengthen 4 wings, and the increase in resistance of each seal ensures the stability of the structure and operation of the welding element.

　　As the number of feathers decreases, feathers, floppy disks and lids are distributed vertically and circumferentially during the welding process. When the metal plate is welded to the wheel cover, processing measures shall be taken to prevent deformation of the welded wheel. When the wheel is in a dynamic balance state, the additional balance mass is fixed at the corresponding position of the wheel disc and the wheel cover, and is welded to ensure the balance of the wheel and prevent the wheel and vibration.

　　Centrifugal fan manufacturers improve the comparison before and after the turbine: the old fan worm, fan inlet, and fan inlet are equipped with new welding wheels, installed on the main engine, and a high-speed driving comparison test is carried out under the same working conditions. Under the same working conditions, the improved gas turbine centrifugal fan has a higher working efficiency and realizes the temperature rise of the main electrode of the L effect. The current of wind turbines is lower than that of turbo centrifugal fans, and it is difficult for wind turbines to exceed the fixed current under continuous operating conditions.

　　Before upgrading the centrifugal wind turbine, 56 wings, panels and multi-wing wind turbine covers can be assembled more easily. When the centrifugal fan manufacturer assembles, the assembly hole of the wing steering wheel is assembled with the plate and wheel cover.
