Dynamic balancing method of fan impeller
The second method: direct test, according to the phase angle and vibration value to calculate the weight, weight and angle (the instrument should have test function)
The third method: direct test, equal angle to add the same mass block, drawing to add weight, this is only suitable for single side balance, and consider the three lines do not hand in the same situation.
First method:1, stop with reflective strip2, initial test3, test weight4, go to trial weight plus counterweight
