COURSE OVERVIEW:

Balancing standards (ISO) and practical field application bridge the gap between theoretical vibration limits and the real-world maintenance of rotating machinery. This course provides a comprehensive exploration of the ISO 21940 family of standards, focusing on the classification of rotors and the determination of permissible residual unbalance. Understanding these standards is essential for achieving the precision required to minimize bearing wear and energy consumption in industrial plants.

The scope of this training involves the application of ISO standards across various equipment types, including pumps, fans, and high-speed turbines. Participants will learn how to translate standard requirements into actionable field balancing procedures, utilizing advanced diagnostic tools to measure and correct unbalance. The coverage extends to the management of "half-key" conventions, the influence of rotor flexibility, and the specific requirements for different balance quality grades.

Furthermore, the course addresses the practical challenges of field balancing in harsh environments. It delves into the use of portable vibration analyzers, the identification of environmental interference, and the documentation protocols required for regulatory compliance. By focusing on both the rigorous ISO framework and the practicalities of field work, the course ensures that technicians and engineers can deliver consistent, high-quality balancing results that meet international excellence benchmarks.

COURSE OBJECTIVES:

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

1. Navigate and apply the ISO 21940 family of balancing standards.
2. Categorize rotors according to ISO 21940-11 (formerly ISO 1940).
3. Calculate permissible residual unbalance based on RPM and mass.
4. Implement the "Half-Key" convention according to ISO 21940-32.
5. Execute field balancing using single-plane and two-plane methods.
6. Utilize phase analysis to differentiate unbalance from other faults.
7. Select the appropriate balance quality grade (G-grade) for equipment.
8. Perform residual unbalance verification (RUV) post-balancing.
9. Manage the challenges of balancing rotors in-situ with limited access.
10. Analyze the impact of environmental vibration on balancing accuracy.
11. Document field balancing results to meet ISO and API requirements.
12. Troubleshoot balancing issues related to thermal growth and looseness.
13. Optimize correction weight placement for maximum vibration reduction.
14. Communicate balancing results and technical reports to plant management.

TARGET AUDIENCE:

This course is intended for vibration analysts, mechanical maintenance engineers, field service technicians, and reliability specialists involved in the in-situ balancing of rotating machinery.

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.
