Mechanical and Rotating Equipment Troubleshooting and Maintenance Training Course
Introduction:
Course Objectives:
Most of plant’s equipment are rotary. Therefore, understanding the principles of rotating equipment is very essential. Identification of failure modes and monitoring methods of failure symptom are important as well, for establishing the most effective maintenance program. This course begins with discussing the definition of rotating equipment, their types and their primary functions, as well as the general characteristics of rotating equipment in relation with their performance. Then, a detailed discussion on primary rotating equipment, namely pumps, compressors, turbines and fans/blowers, will be given. The discussion includes the classification for each type, the performance characteristics and the frequent failure modes. This course is closed with a procedure to conduct alignment of axles and predictive maintenance for rotating equipment.
Who Should Attend?
- Supervisors, Team Leaders and Professionals in Maintenance, Engineering and Production.
- It is suitable for Professionals who expects to become involved at any stage in project applications and applicable maintenance technologies.
