The impeller is an important component part of the fan, in the production of the impeller, unbalanced centrifugal force is generated when the impeller rotates due to uneven materials, blank defects, errors generated by machining and the like, the centrifugal force acts on the machine base through the bearing, so that vibration and noise are generated by machine equipment, bearing abrasion is accelerated, the working precision and working efficiency of the equipment are reduced, the service life of the fan is shortened, even matching looseness and component breakage are caused in severe cases, and great economic loss is caused. Therefore, before the impeller is assembled to the blower, it is necessary to perform balance detection on the impeller to an allowable balance accuracy level or to reduce the amplitude of mechanical vibration generated thereby to an allowable range.
The existing on-site rotor dynamic balance correction technology is widely applied, and in the dynamic balance correction process, balancing weights are required to be welded at the determined positions of the edges of rotor blades. The corresponding angle is calculated by on-site measurement and the position is determined on the fan rotor. Currently, the following disadvantages exist when the position is confirmed on the fan rotor generally through the ruler or through the estimated position after the rotor blade is equally divided: (1) The impellers are all arranged in the shell, so that the ruler is inconvenient to use in the measuring site; (2) The position angle estimated and judged by the equally divided blades is inaccurate.
