METHOD OF ALIGNING SHAFTS BASED ON TEMPERATURE MEASURED DURING OPERATING CONDITIONS

摘要

A method of determining and verifying optimal target alignment values for aligning a pair of adjacently located rotating machines having their shafts coupled together. An alignment engineer enters physical characteristics of each rotating machine into a software directed processing device. The alignment engineer enters ambient and operational temperature information into the processing device. The system calculates initial target alignment values. The machines are aligned and placed in an operational state. The engineer measures operating temperature and the respective thermal expansion. The measured actual operational data is entered into the processing device, which utilizes the actual data to determine improved optimal target alignment values. The engineer utilizes the improved values to complete a final alignment of the pair of adjacently located rotating machines.
