Using the Balanset-1A Instrument

Equipment Preparation

• vibration sensors, optical speed sensor, magnetic base, software package, and included accessories.
• Set up the instrument and connect it to your computer via USB. Verify that the software is correctly installed.

Setting Up the Sensors

• Fix the accelerometers securely to the machine's structure in locations where vibrations are most prominent, ideally near the bearings.
• Position the laser tachometer (phase angle sensor) so that it is aimed at the rotor. Attach reflective tape to the rotor for accurate phase angle reading.

Starting the Program

• 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.

• Bring the rotor to its normal operating rotational frequency.
• The application will acquire data on vibration magnitude, rotational velocity, and phase angle to determine the initial imbalance state.

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

Determining the Corrective Mass

• Based on the measured data, the software automatically calculates the correction weight parameters: mass and installation angle.
• These parameters are displayed on the screen as numerical data and graphs.

Attaching the Corrective Mass

• Install the correction weight on the rotor according to the software's calculations.
• You can conduct interim measurements to confirm that the imbalance is decreasing as expected.

Final Check and Balance Confirmation

• After installing the correction weight, run the rotor again and check the residual vibration level.
• The balancing procedure is finished if the remaining vibration is within the permissible limits specified in ISO 1940.
• Should the vibration still be excessive, repeat the balancing steps, making further adjustments to the corrective weight as needed.

Creating a Balancing Report

• 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.
