Machine Alignment

Overview

Misalignment between motors, pumps, compressors, turbines and gearboxes is one of the most common causes of vibration, bearing damage, seal failures, coupling wear and high energy consumption in rotating equipment. Even small alignment errors can significantly shorten machine life, yet alignment is still often done by eye or with straight edges. Accurate shaft alignment, combined with correct correction of soft foot, pipe strain and thermal growth, is one of the most cost-effective ways to improve the reliability of rotating machinery in industrial plants.

This course provides practical skills in shaft alignment of rotating equipment. Participants learn the types of misalignment and their effects, alignment tolerances, and the preparation needed before alignment, including foundation and baseplate checks, soft foot correction and pipe strain assessment. The course covers rim and face, reverse indicator and laser alignment methods, the use of dial indicators and laser systems, calculation of shim and move corrections, and alignment of vertical machines and machine trains. It also explains thermal growth and hot alignment, coupling types and installation, alignment documentation, common errors and the link between alignment, vibration and machine reliability.

Objectives

• Explain the types of misalignment and their effects on machines
• Apply alignment tolerances for different speeds and machine types
• Prepare machines by checking foundations, soft foot and pipe strain
• Perform rim and face and reverse indicator alignment with dial indicators
• Use laser alignment systems and calculate shim and move corrections
• Account for thermal growth and align vertical machines and trains
• Document alignment work and avoid common alignment errors

Who should attend

Training methodology

The course is highly practical and combines short explanations with hands-on alignment exercises on training rigs using dial indicators and laser alignment systems where available. Participants measure and correct soft foot, take alignment readings, calculate shim and horizontal move corrections by hand and with graphical methods, and compare results with laser systems. Thermal growth calculations are carried out for pumps and compressors. Vibration data from misaligned machines are reviewed to show symptoms. Case studies of failures caused by misalignment are discussed. Each day ends with a short quiz and review.
