Dynamic Balancing What are the factors that lead to uneven rotor mass dispersion in calibration? In order to make the rotor in the operation to adhere to a balanced situation, the dynamic balancing machine is required, as long as the rotor and equipment corrected by the dynamic balance can be put into use relatively safely.
There are various reasons for the formation of rotor imbalance, but the uneven mass dispersion of the rotor is one of the most common reasons
1. The rotor is affected by raw materials or blanks during production. Most of the things we often encounter are due to data problems, and the rotor is unbalanced; For example, the casting blank has pores, looseness, etc., coupled with uneven welding, etc., may cause the imbalance of the rotor.
2. The imbalance of the rotor during the operation. In the process of high-speed operation, it is normal for the rotor to show wear or deformation, and a temperature difference between high or low temperature may occur when rotating very quickly, resulting in rotor deformation, coupled with the relative displacement of centrifugal force, and significant oscillation will occur in long-term operation.
3. Imbalance in the process of rotor processing and assembly. Device errors occur during the assembly of the equipment, which can affect the mass dispersion of the rotor.
4. Imbalance caused by the rotor during the repair process. In the repair process, there is a certain probability that the quality of the rotor will be unevenly dispersed due to normal repairs such as disassembly and replacement of parts, so in order to better ensure the normal operation of the rotor, dynamic balance treatment is also required after repair and maintenance.
