Compressor Deflection Analysis

OXO Compressor Deflection Analysis

Project Information
Project Details:
Periodically evaluate casing movement/deflection.
Predictive analysis of foundation deterioration/issues.
Compare all measurement data to previous inspections.
Develop history for each unit, cold baseline to operational condition monitoring.
Project Description:
Permanent monuments were attached during a mechanical down for each unit. During that time a “cold” baseline was
established for each unit. The baseline inspection would become the comparison for all subsequent inspections for
which casing deflection and movement will be evaluated.
“Hot” checks are periodically scheduled and completed during normal run time. The initial hot check is compared to the cold
baseline and movement/deflection values are provided at each permanent monument location. Each subsequent hot check is then
compared to both the preceding hot check as well as the cold baseline. Movement is tracked from the cold baseline as well as
between each periodic hot inspection.
All movement is depicted in reference to the compressor centerline. An xyz coordinate reference is establish along the
compressor centerline. The X axis represents axial movement along the shaft centerline, either towards or away from the motor…
a + movement is towards the motor and a – movement is away from the motor. The Y axis represents horizontal movement, either
left or right of the shaft centerline… a + value is movement to the left (looking from motor) of the centerline and a – value is
movement to the right (looking from motor) of the centerline. The Z axis represents vertical movement, either above or below the
shaft centerline… a + value is movement above the centerline and a – value is movement below the centerline.
