Detailed Rotor Balancing Process

Equipment Preparation

• accelerometers, laser rpm sensor, mounting stand, software application, and additional tools.
• Connect the device to your PC using the USB interface and confirm the software installation.

Mounting the Sensors

• Attach the vibration sensors firmly to the machine casing in areas with the highest vibration amplitude, usually close to the bearing supports.
• Direct the laser speed sensor towards the rotor and affix reflective tape to the rotor surface to facilitate phase angle measurement.

Launching the Software

• Open the Balanset application on your PC.
• Select the appropriate balancing mode: single-plane or two-plane, depending on the rotor type and your specific requirements.

Measuring Initial Vibration

• 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

• Halt the rotation and mount a test weight at a designated position on the rotor, with the weight's value entered into the software (usually in grams).
• Resume rotor operation, and the program will capture the resulting changes in vibration amplitude and phase.

Calculating the Correction Weight

• 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.
• If necessary, perform intermediate checks to verify that the imbalance is being reduced.

Verification and Balancing Completion

• After installing the correction weight, run the rotor again and check the residual vibration level.
• If the measured vibration falls within the tolerance defined by ISO 1940, the balancing process is considered successful.
• If the vibration is still outside acceptable limits, reiterate the process and fine-tune the compensating weight.

Report Generation

• 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

• Ensure all applied weights and attached sensors are firmly fixed in their designated positions.
• Confirm that the rotor spins freely and quietly, without any unusual sounds or vibrations.
• If the rotor is part of a complex mechanism, verify the proper interaction of all its components.
