High speed rotating components
often experience alignment challenges. Machinery movement occurs due to various
environmental and operating phenomenon. The proper machine positions in the hot
running state can be significantly different than when cold non-running.
A brief discussion of hot/cold alignment analysis follows:
We employ the HCSA system for
collecting and evaluating alignment data. This system provides for
on-site data collection utilizing precision large scale dimensional metrology
equipment. This data may be processed within the HCSA software to help determine
Hot-vs- Cold Alignment
Analysis is a powerful tool for high speed rotating equipment. Using the HCSA
system, we are able to measure various
rotating shafting while components are up and running. HCSA allows for
organized precision data collection.
Data analysis may be used for historical tracking of critical equipment movement
and aid in improved alignment.
Analysis of the data provides Straight
Cold & Hot Shaft Center-Line measured profiles for Vertical & Horizontal views.
Numerous hot/cold statistics, including coupling angle and offset (based on Straight shafting), are
calculated. Multiple stage systems may be measured. Alignment numerical
coordinates are provided for additional post analysis.
