with the Balanset-1A Device
Equipment Preparation
- accelerometers, laser rpm sensor, mounting stand, software application, and additional tools.
- Connect the device to your PC using the USB interface and confirm the software installation.
Sensor Installation
- Mount the vibration transducers securely on the machine's housing where vibrations are most pronounced, typically near the bearings.
- Aim the optical rpm sensor at the rotating shaft and apply a reflective strip to the shaft for phase angle data acquisition.
Launching the Software
- 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.
- 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.
Trial Weight Installation
- 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).
- Resume rotor operation, and the program will capture the resulting changes in vibration amplitude 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
- 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.
Validation and Conclusion of the Balancing Process
- Once the corrective weight is in place, restart the rotor and measure the remaining vibration amplitude.
- 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.
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.
Concluding Steps and Verification
- Verify the secure attachment of all balancing weights and measurement sensors.
- 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.
