Rotating Machinery: Practical Solutions to Unbalance and Misalignment

This course brings you both a theoretical and practical understanding of unbalance and misalignment in rotating equipment. These two conditions account for the vast majority of problems with rotating equipment encountered in the real world.

Resonance and beat frequencies are detailed, along with sources and cures. Also covered are proper inspection procedures, single plan and dual plane methods of balancing rotating equipment, the three circle method of balancing slow speed fans, the advanced rim and face method of precision alignment, and the reverse indicator method of alignment.

Course Objectives

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

• Learn the ways in which vibration can be used to determine the operational integrity of rotating machinery.
• Gain a clear understanding of the relationships between various vibrational characteristics and the associated forces generated within the operating machinery when conditions of unbalance and misalignment are present.
• Find numerous examples and solutions to assist you in understanding the various concepts covered.
