COURSE OVERVIEW:

Balancing of rotating machinery is a specialized engineering discipline focused on correcting the distribution of mass within a rotor to minimize vibration and maximize component life. This course provides an in-depth exploration of the mechanics of unbalance, covering the physics of centrifugal forces and their impact on bearings and structures. Mastery of these techniques is essential for the smooth operation of high-speed assets such as turbines, compressors, and fans.

The scope of this training involves a comprehensive study of balancing methods, ranging from single-plane static balancing to multi-plane dynamic balancing of flexible rotors. Participants will learn how to use advanced vibration analyzers and balancing machines to identify unbalance and calculate the required correction weights. The coverage extends to the application of ISO 21940 balancing quality grades and the practical challenges of field balancing versus shop balancing.

Furthermore, the course addresses the troubleshooting of balancing-related issues, such as thermal unbalance, looseness, and the influence of couplings. It delves into the use of vector math and influence coefficient methods for resolving complex vibration patterns. By focusing on both the mathematical foundations and hands-on practical skills, the course ensures that participants can eliminate unbalance as a source of machinery distress, thereby improving the reliability and efficiency of plant equipment.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

1. Explain the principles of static, couple, and dynamic unbalance.
2. Identify unbalance signatures using vibration spectrum and phase analysis.
3. Utilize the "Single Plane" vector method for simple balancing.
4. Perform "Two Plane" balancing on wide or overhung rotors.
5. Apply ISO 21940 standards to determine appropriate balancing tolerances.
6. Operate horizontal and vertical balancing machines effectively.
7. Execute field balancing on fans, pumps, and motors in-situ.
8. Analyze the behavior of flexible rotors and manage critical speeds.
9. Differentiate between unbalance and other faults like misalignment.
10. Calculate correction weights and placement angles with precision.
11. Implement "Combined" balancing for complex rotor assemblies.
12. Assess the impact of keyways and assembly tolerances on unbalance.
13. Document balancing results and generate final certification reports.
14. Optimize the balancing process to reduce machine downtime.

TARGET AUDIENCE:

This course is intended for mechanical technicians, vibration analysts, millwrights, and workshop supervisors involved in the maintenance and repair of rotating equipment.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
