Background
The dynamic balance is a leveling method for measuring the position of the unbalanced weight of the rotor in a rotating state and determining the position and the size of the balance weight to be added. The unbalance generated during the rotation of the rotor is caused by the fact that the mass center of each micro-segment of the rotor is not strictly positioned on the rotating axis, the unbalance can cause the transverse vibration of the rotor and cause the rotor to be subjected to unnecessary dynamic load, the normal operation of the rotor is not facilitated, and therefore most of the rotors need to be dynamically balanced. In the machine manufacturing or maintenance, the dynamic balance becomes a process, the dynamic balance not only can eliminate the couple of the dynamic unbalance, but also can eliminate the centrifugal force of the static unbalance, and the dynamic balance can be used for finding the balance of various columnar rotors, such as the rotor of a centrifugal compressor, the rotor of a large-scale motor and the like. The dynamic balance performance is an important performance of the fan, the traditional fan carries out dynamic balance correction mainly by operating on an impeller, namely welding a balancing weight on the impeller after the unbalance of the impeller is obtained through measurement, and then adjusting the weight and the position of the balancing weight by continuously welding the balancing weight and carrying out gas cutting on the welded balancing weight until the dynamic balance performance of the impeller meets the manufacturing requirement. However, in the existing method for performing action balance correction on the impeller, the operation of electric welding and gas cutting is required to be performed on the production site, the process is troublesome, time-consuming and labor-consuming, the electric welding and gas cutting are easy to cause environmental pollution and potential safety hazards, and the electric welding and gas cutting are easy to deform the impeller for some special impellers such as cast impellers and impellers which need to operate under special environmental conditions, so that the product quality of the impeller is influenced.
SUMMERY OF THE UTILITY MODEL
