| Abstract: | Aiming at the problems of big vibration for frequency conversion motor after the conden?sate pump rebuild, tests and analyzes the vibration, through the way of dynamic balancing and increas?ing rigidity of the shell of motor, eliminates the vibration. The result shows that the causation of con?densate pump vibration is due to the connection way leading to the shafting rigidity decrease and hap?pen resonance. |
