And malfunction of the rotor member generally refers to the quality of the rotating machine with respect to the axis of the rotating shaft of the occurrence of abnormal vibration caused by the eccentric balancing device. Field Balancing refers to the case without removing the device directly rotor components balancing correction (typically require special equipment). Before explains how balancing, let us know, understand vertical balancing bad maneuver balance manifested adverse effects on the device characteristics and balancing: an adverse effect on balancing device generates an exception: 
  1. reduce the life expectancy of the device, particularly in the early performance of bearing damage; 
  2. shorten the maintenance cycle of the equipment; 
  3. The increase in equipment maintenance costs; 
  4. affect product quality; 
5. deterioration of the working environment.
