Shaft misalignment is one of the most frequent reasons why rotating machinery vibrates harmfully. This extensive course teaches the student the importance of precise shaft alignment as well as the widely used techniques for achieving it. Dial indicators are used for alignments in the classroom and in real fields.

Course Objectives:

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

· Apply and gain a comprehensive understanding of alignment

· Identify the importance of proper shaft alignment and identify the symptoms of misalignment

· Discuss the foundations, baseplate and piping effects and enumerate various types of couplings, flexible and rigid couplings

· Identify alignment and coupling tolerances and perform the preliminary alignment checks

· Enumerate the different alignment methods(dial indicator and laser ) and state the advantages of each alignment method.

· Apply alignment procedures, analyze mathematical relationships and perform alignment calculations and graphics.

· Carry out adjustments for thermal growth, “hot” alignment vs “cold” alignment and moving machinery in the field

· Evaluate alignment considerations for specific equipment such as; electric motors,

· pumps, gearboxes, compressors, cooling towers, blowers & fans & internal combustion engines

· Prevent misalignment severity and vibrations caused by misalignment.

Who Should Attend?

The training program is designed and targeted to inspection & technical support engineers & supervisors and technicians who are dealing with the operation and maintenance of rotating equipment and who are running alignment and wish to improve their knowledge and skills
