BRM Training Course

08:00 AM - 05:00 PM

Explores the art and science of balancing machinery and is recommended after completion of the BMV training course. All Vibration Institute instructors are Category IV certified and experienced vibration analysts. Course Instructors are subject to change without prior notification.

BALANCING of ROTATING MACHINERY (BRM)

All registered attendees in the Balancing of Rotating Machinery training course are provided class notes, a workbook containing problems and exercises, a scientific calculator, and balancing tools. Workshops are scheduled to illustrate theory and applications. Registrants are welcome to bring their equipment for the hands-on balancing exercises.

DAY ONE

• Basic Aspects of Machine Balancing
• Purpose, mass unbalance force and causes, rotor classification, techniques, equipment, pre-balancing checks, critical speeds, trial weight selection/placement, and pitfalls
• Vibration Testing and Analysis
• Amplitude and phase measurements, orbits, Bodé plots, polar plots, casing/proximity probe measurements, whirling, transient testing, and vibration analysis
• Single-Plane Balancing Techniques
• Vector and four-run methods, critical speeds, modes, heavy spot high-spot relationship, balance sensitivity, phase lag, trial weight selection, weight splitting, criteria and standards
• Workshop I: Balancing Topics
• Class exercises on basic principles.

DAY TWO

• Workshop II: Single-Plane Balancing
• Hands-on exercises using a rotor kit, vector method, single-plane balancing; registrants can bring an instrument or use the Institute’s equipment
• Two-Plane Balancing Techniques
• Influence coefficient and static/couple methods, calculator and graphical methods, one-shot balancing-single plane
• Workshop III: Two-Plane Balancing
• Vector and four-run methods, critical speeds, modes, heavy spot high-spot relationship, balance sensitivity, phase lag, trial weight selection, weight splitting, criteria, and standards
• Workshop IV: Two-Plane Balancing
• Static-couple method, class exercises

DAY THREE

• Workshop V: Two-Plane Balancing
• Class exercises
• Workshop VI: Two-Plane Balancing Coefficients
• Class exercises.
• Turbine/Generator Balancing

• Roll Balancing
• Weight placement, critical speeds, bow effects

DAY FOUR

• Fan Balancing
• Balancing techniques (single- and two-plane), overhung fans, balance
• sensitivity, critical speeds, case histories
• Shop Balancing Techniques
• Sensor selection, plane selection, and procedures
• Balancing Case Histories
• Balancing in the field, procedures, strategies, and pitfalls
• Training Examination on Course Content (1.5 hours)
