Practical Field Balancing

PRACTICAL FIELD BALANCING

Are you unsure whether your machine is dealing with unbalance or some other issue? Do you know how to confirm if unbalance is the main problem? Do you "chase your tail" when you try to balance a machine? Do you know when to stop your balance procedures?

Our Field Balancing Seminar may be just what your site personnel need.

  • OVERVIEW

    • 3-Day Class: Tuesday - Thursday, 8am - 5pm
    • Optional Certification Testing is available Thursday afternoon

    This 3-day seminar provides HANDS-ON practice with your company’s exact field balancing equipment.  It is recommended the students bring their own field balancing analyzer to class to gain practical knowledge and experience they can bring back with them. 


    This class also helps students learn how to determine if balance is the primary source of vibration and what type of unbalance condition exists on the machine.  Students will learn various balance techniques including single-plane and dual-plane balancing and will be introduced to no-phase and one-run balance techniques. 


    Students will also learn industry standards for balancing tolerances and how to determine what is the proper amount of unbalance to give your company better field balances to help you get the most life out of your equipment.

  • PRIMARY OBJECTIVES

    • Instruct how to confirm that unbalance is one of the dominant problems (using straightforward spectral & phase analysis).
    • Use Hands-on Demonstrations to teach how to properly balance a variety of machinery using both graphical methods and data collectors with balancing programs.
    • Teach single-plane and two-plane field balancing techniques using a variety of today’s data collectors.
    • Teach special balancing techniques required on overhung rotors.
    • Provide and clearly explain today’s balancing tolerances.

  • PREREQUISITES

    • Previous vibration analysis experience is recommended but is not required prior to attending this seminar.
    • Previous field balancing experience is helpful but is not required prior to attending this seminar.
    • General familiarity with using today’s data collectors or portable balancing instruments is also beneficial (a variety of such instruments will be demonstrated during interactive class exercises).
    • Good math skills and the ability to use and interpret graphs and tabular information will be beneficial in order to maximize understanding.
