The course goes through a systematic methodology to effective failure analysis and troubleshooting, including goal achievement, checklists use and constituting a failure analysis team. Referring to specific case studies, example centrifugal pumps, it will be shown that such a systematic schedule of actions can lead to significant failure decreases in many types of machinery. Through pumps and compressors examples, vendor selection procedure is highlighted as well as methods for reliability review.
By the end of the course, participants will be able to:
Employ systematic techniques on machinery failure analysis, vibration and predictive maintenance.
Identify machinery failure patterns covering the nature of failure, the types of equipment failures and their categorizations
Apply machinery diagnostic testing, metallurgical failure analysis methodology, machinery component analysis and reliability improvement.
Carryout machinery troubleshooting and root cause failure analysis (RCFA).
Analyze vibration signal for different faults and machineries.
Differentiate between the factors of human reliability through classification of human error and human reliability analysis, familiarize the different reliability tools using life cycle cost analysis and life data analysis and discuss the key elements of reliability engineering and how to manage assets in projects.
Who should attend
This course covers systematic techniques in maintenance and reliability management to assist maintenance management team in delivering maximum reliability and availability of equipment at the lowest possible cost. The course will present techniques designed to improve the effectiveness of maintenance management activities, to ensure that physical assets perform their required functions, operate reliably, and support corporate goals. It is essential for all maintenance and reliability management staff.
