Embodiment 1
[0039] In October 2012, a fan in a factory vibrated. The double-sided dynamic balancing method for solving fan vibration of the present invention is used for dynamic balancing. Schematic diagram of the fan rotor figure 1 As shown, at the level of the 1# and 2# bearing bushes at both ends of the fan (measuring point 1 and measuring point 2 in the figure), install the vibration sensor of the vibration meter respectively, and set a light-emitting sheet at the power input shaft of the fan to reverse the direction of the fan. If it is positive, otherwise it is negative. Set a phase sensor under the position of the luminescent sheet. When the fan is running, measure the horizontal vibration value OA corresponding to the bearing bushes at both ends. 1 with OB 1, and the corresponding phases of the two horizontal vibration values are measured simultaneously. Weld a 500g test counterweight on the same position 40° on both sides of the fan rotor, reverse the steering angle measurem...
