Using the Balanset-1A Instrument

Preparing the Necessary Tools

• 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.

Setting Up 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.

Launching the Software

• Launch the Balanset software on your computer.
• Choose the correct balancing method (single or two-plane) according to the rotor configuration and the balancing task.

Taking Baseline Vibration Readings

• Bring the rotor to its normal operating rotational frequency.
• The software will measure the vibration level, rotational speed, and phase angle. This data establishes the current imbalance condition.

Trial Weight Installation

• Stop the rotor and attach a trial weight at a specific location on the rotor. The weight's mass can be specified within the software (e.g., in grams).
• Restart the rotor, and the software will record the changes in vibration level and phase angle.

Computing the Compensating Weight

• Using the acquired measurements, the program automatically determines the required corrective weight's mass and angular position.
• The calculated values are presented on-screen in both numerical and graphical formats.

Mounting the Compensating Weight

• Attach the computed compensating weight to the rotor as indicated by the software's output.
• 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.

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.

Post-Balancing Checklist

• Double-check that all weights and sensors are securely fastened.
• 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.

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