EQiblyHow Posted January 25 Share Posted January 25 Detailed Rotor Balancing Process Getting the Equipment Ready accelerometers, laser rpm sensor, mounting stand, software application, and additional tools. Set up the instrument and connect it to your computer via USB. Verify that the software is correctly installed. Sensor Installation Attach the vibration sensors firmly to the machine casing in areas with the highest vibration amplitude, usually close to the bearing supports. Aim the optical rpm sensor at the rotating shaft and apply a reflective strip to the shaft for phase angle data acquisition. Software Startup Initiate the Balanset program on your computer. Configure the software for either single-plane or two-plane balancing, based on the rotor's characteristics and the desired outcome. Initial Vibration Measurement Run the rotor up to its operating speed. The software will measure the vibration level, rotational speed, and phase angle. This data establishes the current imbalance condition. Mounting the Test Weight Bring the rotor to a standstill and affix a trial weight at a predetermined point on the rotor, specifying its mass in the software (typically in grams). Resume rotor operation, and the program will capture the resulting changes in vibration amplitude and phase. Determining the Corrective Mass Based on the measured data, the software automatically calculates the correction weight parameters: mass and installation angle. The calculated values are presented on-screen in both numerical and graphical formats. Installing the Correction Weight Install the correction weight on the rotor according to the software's calculations. Periodic checks can be performed to ensure the balancing procedure is effectively reducing the vibration. Validation and Conclusion of the Balancing Process With the compensating weight attached, operate the rotor and assess the level of any residual vibration. The balancing procedure is finished if the remaining vibration is within the permissible limits specified in ISO 1940. If the vibration level remains high, repeat the process with further weight adjustments. Generating a Documentation of the Balancing Results The program stores the balancing data, allowing you to generate and print a comprehensive report including vibration measurements, corrective weight details, and its angular placement. Post-Balancing Checklist Verify the secure attachment of all balancing weights and measurement sensors. Confirm that the rotor spins freely and quietly, without any unusual sounds or vibrations. If the rotor operates within a larger assembly, check the functionality and interplay of all interconnected parts. This process allows for precise imbalance correction, reducing vibration and extending equipment life.
