Course Overview

This course comprehensively explore vibration analysis, balancing and alignment techniques. Vibration analysis is a predictive maintenance technique covering the early diagnosis of faults in machinery. Balancing and Alignment cover the practical aspects of improving the performance of all the machinery components. The course also covers precision maintenance techniques.

Course Details

This 12-week course, led by an industry expert will provide you with practical, in-depth view of the vibration analysis, balancing and alignment techniques.

The course provides a detailed examination of the detection, location and diagnosis of faults in rotating and reciprocating machinery using vibration analysis. The basics and underlying physics of vibration signals are first examined. The acquisition and processing of signals is reviewed followed by a discussion of machinery fault diagnosis using vibration analysis, and rectifying the unidentified faults.

The important topic of balancing is then discussed drawing on practical examples. Alignment and other machinery faults are then covered. Other often neglected areas of particle and chemical analysis, temperature monitoring and failure analysis are covered in practical detail. The course is concluded with a set of practical rules for a precision maintenance program including issues such as machines to monitor, managing the data usefully and scheduling maintenance.

You will have an opportunity to discuss precision maintenance for rotating machinery and associated applications, operations, maintenance and management issues. The focus will be on the most up-to-date information and best practice. Towards the end of the course, you will have developed the skills and ability to recognize and solve precision maintenance issues in a structured and confident manner, in working and improving the reliability and performance of their rotating machinery.
