Portable Balancer Overview

The Balanset-1A is a dual-channel vibration balancing and analysis device designed to work with a variety of rotor types including crushers, fans, mulchers, augers on combines, shafts, centrifuges, turbines and many others. It provides high precision and efficient balancing through a range of advanced features and technologies.

 

    Features:

    The Balanset-1A device offers a comprehensive range of functionalities for rotor balancing and vibration analysis:

    Vibrometer Mode:

    • Tachometer: Accurately measures rotational speed (RPM).
    • Phase: Determines the vibration signal’s phase angle for precise analysis.
    • 1x Vibration: Analyzes the fundamental frequency component.
    • FFT Spectrum: Offers detailed frequency spectrum analysis of vibration signals.
    • Overall Vibration: Monitors overall vibration levels.
    • Measurement Log: Saves measurement data for further analysis.

    Balancing Mode:

    • Single Plane Balancing: Reduces vibration by balancing rotors in a single plane.
    • Two Plane Balancing: Achieves dynamic balancing by balancing rotors in two planes.
    • Polar Graph: Accurately places weights by visualizing imbalance in a polar graph.
    • Restore Last Session: Resumes previous balancing sessions for convenience.
    • Tolerance Calculator (ISO 1940): Computes acceptable balancing tolerances according to ISO 1940.
    • Grinding Wheel Balancing: Utilizes 3 counterweights for balancing grinding wheels.

    Charts:

    • Overall Charts: Visual representation of overall vibration.
    • 1x Charts: Displays vibration patterns of the fundamental frequency component.
    • Harmonic Charts: Indicates the presence and impact of harmonic frequencies.
    • Spectrum Charts: Graphical representation of the frequency spectrum for detailed analysis.

    Additional Capabilities:

    • Archive: Stores and retrieves past balancing sessions.
    • Reports: Generates detailed reports of balancing outcomes.
    • Re-balancing: Facilitates the repetition of the balancing process with saved data.
    • Serial Production Balancing: Suitable for rotor balancing in serial production.

    Balanset-1A also supports both Imperial and Metric systems, ensuring global compatibility and convenience.

    Then make step-by-step operations as shown in the Table 1 below.

     

    Table 1. Step-by-step operations

     

    Run 0 - Start-up without test weight.
    2. Run the machine at its operating speed (be sure that operating  speed is far from resonance frequency of construction) 
      3. Click on F9-Start and measure  the vibration  level and  phase angle  in turn without test weight.
    Duration of the measuring process  may amounts  2-10 sec.

    Run 1 - Test weight in plane 1
    4. Stop the  machine  and mount a test weight of suitable  size  arbitrarily in plane 1.
    5. Start up the  machine, click on F9-Run and measure the new vibration level and phase angle. Duration of the measuring process may amounts  2-10 sec.
    6. Stop  the machine and remove the  test  weight

    Run 2 - Test weight in plane 2
    7. Mount a trial weight of  suitable size in plane 2 . 
    8. Start  the  machine again, click on  F9-Runand measure the vibration level and phase angle once more.

    9. Stop  the machine and remove  the  test  weight

    RunC
     11. Mount the correction (balance) weights  at the  positions   indicated  in popup form  at the same radius   as the  test (trial) weights (as shown in the figure in right column).  
     12. Start up  the  machine  again and   measure the  amount of residual  unbalance in  the rotor , to see how  successful  the  balancing  job has been .  


    After balancing you can save influence coefficient balancing (F8- coefficients) and other information (F9- Add to archive) and use it later. (see 4.3, 4.4)
