From simple rotors to complex constructions: handles it all

Detailed Rotor Balancing Process

Equipment Preparation

• 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.

Mounting the Sensors

• 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.

Software Startup

• 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.

Initial Vibration Measurement

• Bring the rotor to its normal operating rotational frequency.
• The program will record the vibration amplitude, rpm, and phase, providing a baseline measurement of the existing imbalance.

Attaching the Trial 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).
• Run the rotor again, allowing the software to measure the effects of the trial weight on vibration and phase.

Determining the Corrective Mass

• Using the acquired measurements, the program automatically determines the required corrective weight's mass and angular position.
• These parameters are displayed on the screen as numerical data and graphs.

Installing the Correction Weight

• Attach the computed compensating weight to the rotor as indicated by the software's output.
• You can conduct interim measurements to confirm that the imbalance is decreasing as expected.

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.

Generating a Documentation of the Balancing Results

• The balancing results are saved in the software's archive. You can create and print a report containing vibration data, correction weight mass, and its installation angle.

Final Recommendations

• Ensure all applied weights and attached sensors are firmly fixed in their designated positions.
• Ensure the rotor rotates smoothly and without excessive noise.
• If the rotor operates within a larger assembly, check the functionality and interplay of all interconnected parts.
