This 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 then reviewed followed by a discussion of machinery fault diagnosis using vibration analysis. Hereafter the important issue of rectifying faults that have been identified using vibration analysis is covered.
The course is concluded by a review of the other techniques of predictive maintenance such as oil and particle analysis, ultrasound and infrared thermography. The latest approaches and equipment used together with current research techniques in vibration analysis are also highlighted in the course.
Upon successful completion of this course, the delegates will be able to:
- Understand the fundamental technology of rotating and reciprocating machines, in terms of how they work and how they fail
- Recognize wear and fatigue related failure mechanisms and the role of lubrication
- Demonstrate the interaction of the machine with the process and the need for maintenance and condition monitoring personnel to work more closely together
- Inspect and maintain machinery and to make informed decisions about the condition of plant
- Explain an introduction to condition based maintenance and condition monitoring and dispel rumors and demonstrate capabilities
Extensive use is made of case study material to underline the key aspects of the course and to give delegates exposure to current best practice.
