ACQUIP ServicesWhat Qualifies as a Machine Train?
• A Machine Train should have at least three separate machines
• The feet must be connected by at least two couplings.
Conventional Plant Machine Trains
• Motor-Gearbox-Compressor.• Turbine HP-Turbine LP- Generator.• Engine-Gearbox-Pump.• Boiler Feed Pump-Turbine-Gearbox-Booster
Pump.
What is a Complete Machine Train Alignment?
• Recognize the Machine Train as a Whole.• Evaluate Alignment targets from the
Manufacture or calculated by measuring dynamic movement.
• Apply the fundamentals alignment principles to ensure proper shaft alignment.
• Flexible, more alternatives of components to move than a single coupling alignment.

Clean Up the Mess• Remove all dirt and

objects
Checking List
Rough Soft Foot • Loosen all hold down
bolts• Fill any obvious gapsCommon Issues• Bolt bound• Base bound
Identify Coupling Type
• Rigid• Flexibl
e• Spacer
Readings Performance. Keep It Simple!
• Take all measurements first.
• Keep it Simple, view alignment as a whole.
Moves Selection
• Decide what is movable
• Fix points, not components
• Horizontal and vertical fixed points can be different
Dynamic Movement
• Consider Coupling Targets
• Growth at the feet• Analyze Dynamic
Movement• Compare measured
Changes
Considering Targets
• Coupling Manufacturer
• Machine Manufacturer
• In-House Specification
Growth at the Feet
Theoretical calculation.• Material Constant• Distance between
center of shaft and machine feet• Delta Temperature
Analyze Dynamic Movement
• Across the coupling
• At the bearing bracket
Combine & Compare Alignment Information
• Misalignment readings, Coupling Targets
• Measured dynamic movement

Machine Train Benefits• A full profile of the machine train is entered into
the computer, so it can be looked as a whole rather than each coupling at a time.
• Best-case scenarios can be instantly tested in the computer before actually performing them and discovering you are bolt bound.
• All machine train dimensions and readings are stored in the computer, and can be recalled for further machine train alignment needs.
