Precision Field Balancing

Precision Field Balancing

Rotor unbalance is one of the most common causes of excessive vibration in rotating machinery. If it is not corrected properly, it can increase dynamic forces, damage bearings and seals, loosen mechanical components, increase energy consumption, and shorten machine life.

The LGP Institute Precision Field Balancing Course provides a practical and systematic understanding of balancing rotors directly in their operating environment.

Participants will learn how to confirm that vibration is caused by unbalance, collect stable amplitude and phase measurements, select a safe trial weight, calculate the required correction, and verify the final balancing result.

The course explains both the practical balancing procedure and the principles behind the measurements. This enables participants to understand the instructions provided by a balancing instrument, identify unreliable data, and recover when a balancing job does not proceed as expected.

What You Will Learn

• Fundamentals and benefits of precision rotor balancing
• Causes and effects of rotor unbalance
• Static, couple, and dynamic unbalance
• Relationship between vibration, phase, speed, weight, and radius
• How to determine whether unbalance is the real problem
• Preparing the machine for a field-balancing job
• Selection and installation of vibration and phase sensors
• Measuring stable vibration amplitude and phase
• Understanding vectors and polar plots
• Heavy spot and high spot relationships
• Selecting a safe and effective trial weight
• Trial-weight placement and safety considerations
• Single-plane field balancing
• Two-plane field balancing
• Static-couple balancing
• Balancing overhung rotors
• Influence-coefficient calculations
• Splitting and combining correction weights
• Moving weights to a different radius
• Performing trim-balance runs
• Four-run balancing without phase
• Common balancing errors and recovery techniques
• Evaluating residual unbalance
• Balancing tolerances and relevant ISO principles
• Documenting the final balancing result

Who Should Attend?

• Vibration analysts
• Mechanical maintenance technicians
• Reliability and maintenance engineers
• Condition monitoring specialists
• Rotating equipment technicians
• Commissioning personnel
• Maintenance supervisors
• Professionals responsible for fans, blowers, pumps, motors, and other rotating machinery

Course Outcome

After completing this course, participants will be able to prepare a field-balancing job, verify the presence of unbalance, select a suitable trial weight, collect reliable amplitude and phase readings, calculate correction weights, and perform single-plane or two-plane balancing.

Participants will also understand how to evaluate the final vibration level and recognise situations where another mechanical fault may be preventing a successful balance.
