Description

The course will provide a refreshment of knowledge for the how Rotating equipment work and what are main problems facing it during operations of them. Also, it will provide a solid foundation for technologists moving into a machine monitoring and diagnostic role

It gives a detailed advanced treatment of the detection, location and diagnosis of faults in Rotating and Reciprocating Machinery. Industrial case study and examples are used throughout the course to emphasize key points and to underline the relevance and applicability of the topics being addressed.

Maintenance spare part stores have to function well, see illustration. Maintenance Planning and Scheduling is critical for every successful individual and company.

This comprehensive 5-day program has been designed to all Industrial fields to benefit both new professionals as well as experienced professionals. It covers advanced best maintenance practice that a qualified professional would require to carry out his duty starting with the first steps and building up in a stair case fashion to a fully functional maintenance organization.

Course Objectives

Upon successful completion of this course, the delegates will be able to:

  • Know when and how to conduct a physical failure analysis
  • Determine basic material properties including heat treating mechanisms, work hardening, and the effects of temperature changes on material properties
  • Identify the differences in appearance between ductile overload, brittle overload, and fatigue failures
  • Explain high cycle fatigue and how to differentiate between high stress concentrations and high operating stresses
  • Explain low cycle fatigue and unusual fatigue situations
  • Describe lubrication and its influence on the three basic bearing designs
  • Recognize ball and roller bearings, gears, fasteners, V-belts, and synchronous belts
  • Use a detailed and systematic approach, practical plant failure analysis thoroughly explains the four major failure mechanisms—wear, corrosion, overload, and fatigue—as well as how to identify them
  • Recognize how these mechanisms appear in various components and supplies convenient charts that demonstrate how to identify the specific causes of failure
