Rotor Balancing Tutorial
MetadataShow full item record
The purpose of this tutorial is to describe details related to shop and field balancing of turbomachinery. The target machinery is API type turbomachinery such as steam turbines, compressors, and other rotating machinery that is common in refining and petrochemical plants. An introduction to shop balancing includes a review of current practice as it relates to shop balancing of API rotors. Included in the description and discussion is a review of API shop balancing methods as well as a review of ISO standards related to shop and field balancing that are referenced by API standards. Greater emphasis is presented in this tutorial on field balancing, which applies to balance correction in situ on rotating machinery and similarly applies to methods and techniques used when conducting high speed shop balancing.
