Then experiment on the mainshaft unit's dynamic balance is performed using a dynamic balancing tester. 并在动平衡试验机上对主轴进行了动平衡实验。
After several times of dynamic balance tests and modifications, the vibration and swing of generating units are controlled within the allowances. 通过多次动平衡试验与校正，使机组的振动与摆度控制在规范允许的范围内。
