Rotor balancing is a critical process for minimizing vibrations and prolonging the lifespan of rotating machinery. This article aims to provide a comprehensive, step-by-step guide to conducting a two-plane rotor balancing operation using the Balanset-1A device. This method ensures high-precision dynamic balancing of the rotor in its operating condition.
Step-by-Step Balancing Process
- Mount Vibration Sensors: Position the vibration sensors perpendicular to the axis of the rotor’s rotation. Ensure they are securely attached to minimize noise in the data.
- Tachometer Installation: Place the tachometer on its magnetic stand, ensuring it is aligned with the rotor.
- Reflective Tape: Apply a strip of reflective tape on the pulley or rotor. Aim the RPM sensor towards the tape.
- Device Connection: Connect the sensors to the Balanset-1A device, connect the Balanset-1A to a laptop equipped with the necessary software.
- Program Initialization: Launch the Balanset software on the laptop.
- Mode Selection: Choose the option for “Two-plane balancing.”
- Data Entry: Enter the rotor’s name and its location in the software interface for record-keeping.
- Test Weight Data: Measure the test weight and note down its weight and radius of installation in the software.
Measurement and Analysis
- Initial Measurement: Start rotation to measure the initial level of vibrations.
- First Plane Test Weight: Mount the test weight in the first plane of the rotor. The first plane correlates to the location of the first sensor.
- Data Collection: Start rotation the rotor and take a second measurement.
- Validity Check: Verify that the vibration or phase shift has changed by at least 20% compared to the initial measurement. This ensures the test weight has been placed accurately.
- Second Plane Test Weight: Remove the test weight from the first plane and install it on the second plane, which corresponds to the second sensor’s location.
- Data Collection: Start rotation again to collect the third set of measurements.
- Software Recommendations: The software will analyze the data and provide the amount of weight and the angle at which to install the correction weights on the first and second planes.
- Weight Removal: Remove the test weight from the rotor.
- Correction Weight: Measure and prepare the correction weights as indicated by the software.
- Weight Installation: Weld the correction weights at the angles specified by the software.
- Final Test: Rotate the rotor again to ensure that the balancing was successful.
- Additional Weight: If the software suggests further corrections, adjust the weight accordingly and confirm the balance once more.
As outlined above, rotor balancing is a systematic process that is greatly simplified and made more accurate with the use of the Balanset-1A device. This method ensures that you achieve a dynamically balanced rotor, resulting in minimized vibrations and increased operational longevity.
