Background

The high-speed rotating machinery is greatly influenced by materials, and the rotor system of the machine is unbalanced and has faults caused by impact, corrosion, abrasion and coking. While a vibration failure of the rotating machine results from an unbalance of the rotor system for 70%. Generally, a maintainer removes a rotor with large vibration, directly replaces an impeller and the like, and operates after reinstallation, so that the purpose of reducing vibration is achieved. However, due to the existence of the original unbalance amount of the rotating component, the vibration sometimes still exceeds the standard allowable value after the machine is operated. In order to prevent machine damage, threaten the safety of field personnel and ensure the normal operation of production, dynamic balance correction is required. The vibration of the rotating shaft is aggravated due to the fact that the blades of the rotating shaft in the mowing cutter head mow for a long time, and if the blades are not adjusted in a dynamic balance mode, the blades are easy to fly out to hurt people, and safety accidents are caused.
