The course covers how these machines work on process, mechanical aspects, wear, lubrication and troubleshooting by vibration analysis and other techniques. The course provides participants with knowledge for inspecting and monitoring compressors, and details how to make fault detections and diagnoses. Emphasis is placed upon the importance of a combined condition monitoring and strip-down inspection approach to maintenance. Extensive use is made of case study material to underline the key aspects of the course and to give the delegates exposure to current best practice.
