What 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.

3. Conventional Plant Machine Trains
• Motor-Gearbox-Compressor.
• Turbine HP-Turbine LP- Generator.
• Engine-Gearbox-Pump.
• Boiler Feed Pump-Turbine-Gearbox-Booster Pump.

4. 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.

5. Easier than a Single
Coupling Alignment
More options on what
points can be moved

6. Problems with Machine Train
Alignment
Bold Bound
Base Bound

7. ACQUIP Services
Walking Through the
Procedure
Safety First
• Lock out/Tag
out!

8. ACQUIP Services
Walking Through the
Procedure
Clean Up the Mess
• Remove all dirt and
grease
• Replace rusty Shims
• Check for unwanted
objects

9. Checking
List
Rough Soft Foot
• Loosen all hold down
bolts
• Fill any obvious gaps
Common Issues
• Bolt bound
• Base bound

10. Identify Coupling Type
• Rigid
• Flexible
• Spacer

11. Readings Performance. Keep It
Simple!
• Take all measurements
first.
• Keep it Simple, view
alignment as a whole.

12. Moves
Selection
• Decide what is movable
• Fix points, not
components
• Horizontal and vertical
fixed points can be
different

13. Dynamic Movement
• Consider Coupling Targets
• Growth at the feet
• Analyze Dynamic
Movement
• Compare measured
Changes

14. Considering Targets
• Coupling
Manufacturer
• Machine
Manufacturer
• In-House

15. Growth at the
Feet
Theoretical calculation.
• Material Constant
• Distance between center
of shaft and machine feet
• Delta Temperature

16. Analyze Dynamic
Movement
• Across the coupling
• At the bearing
bracket

17. Combine & Compare Alignment
Information
• Misalignment readings,
Coupling Targets
• Measured dynamic
movement

18. Graph It Out!

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.

20. Why ACQUIP SphereAction™ is The best Choice
