    Employing the Balanset-1A System 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. Software Startup Open the Balanset application on your PC. Choose the correct balancing method (single or two-plane) according to the rotor configuration and the balancing task. Measuring Initial Vibration


    2-Camera_01

    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


    3-Camera-2_01

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


    5-Camera_01

    Computing the Compensating 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.


    Bs1 Manual

    Installing the Correction 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.


    1-Camera-2_01

    Final Check and Balance Confirmation 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. 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. Post-Balancing Checklist Double-check that all weights and sensors are securely fastened. Check that the rotor's rotation is smooth and free from undue noise or vibration. In cases where the rotor is integrated into a more complex system, ensure the correct operation and interaction of all related components.

    Following this procedure enables accurate balancing, minimizes vibration, and prolongs the service life of the equipment.
