2 Days:
Who should attend?
Plant mechanics, millwrights and maintenance engineers are responsible for the health and reliability of rotating equipment. In this course, participants will learn how to accurately align direct coupled machine shafts.
The course begins with the fundamental principles behind shaft to shaft alignment and concludes with students conducting a series of alignment exercises using conventional alignment tools. The two methods; straight edge alignment, and rim and face alignment will be covered. This two-day course is taught hands-on with standard alignment tools, demonstration models, and simulation software.
- Explain the costly effects of misalignment
- Identify the symptoms of misaligned rotating equipment
- Diagnose and solve soft foot and eccentric runout problems
- Set up dial indicators for rim and face alignment work
- Take accurate alignment readings and measurements
- Use simple graphing and formulas to analyze the readings taken
- Make changed to vertical shims taking thermal growth offsets into account
- Complete successful horizontal moves and confirm final alignment
