OPERATION MAINTENANCE AND INSPECTION OF ROTATING MACHINERY

OBJECTIVE

The course outlines the general technology of the machines and their auxilliaries. It covers how

machines works on process, the mechanical aspects, wear and tear, lubrication, and troubleshooting by vibration analysis and others techniques, thus providing participants with the necessary knowledge for inspecting machinery and making a diagnosis.

At the end of the course, the participants will be able to :

• understand the basic principles of rotating equipment component function
• learn to apply these principles to optimize site condition monitoring and predictive maintenance techniques.

COURSE OUTLINE
