Detailed Rotor Balancing Process

Getting the Equipment Ready

• vibration sensors, optical speed sensor, magnetic base, software package, and included accessories.
• Connect the device to your PC using the USB interface and confirm the software installation.

Sensor Installation

• Fix the accelerometers securely to the machine's structure in locations where vibrations are most prominent, ideally near the bearings.
• 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.
• 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 program will record the vibration amplitude, rpm, and phase, providing a baseline measurement of the existing imbalance.

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).
• Restart the rotor, and the software will record the changes in vibration level and phase angle.

Determining the Corrective Mass

• The software uses the measured values to automatically compute the necessary compensating weight's magnitude and placement angle.
• The calculated values are presented on-screen in both numerical and graphical formats.

Mounting the Compensating Weight

• Mount the calculated corrective weight onto the rotor at the specified location and angle.
• If necessary, perform intermediate checks to verify that the imbalance is being reduced.

Final Check and Balance Confirmation

• With the compensating weight attached, operate the rotor and assess the level of any residual vibration.
• If the measured vibration falls within the tolerance defined by ISO 1940, the balancing process is considered successful.
• If the vibration level remains high, repeat the process with further weight adjustments.

Report Generation

• All balancing results are logged and archived within the software, from which you can produce a printable report summarizing the vibration levels, compensating weight, and its installation position.

Concluding Steps and Verification

• 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.

By implementing this method, you can effectively eliminate imbalance, reduce vibration levels, and increase the lifespan of the machinery.
