本文件规定了对带有液膜轴承的各类燃气轮机和蒸汽轮机进行振动诊断时应考虑的具体程序指南。 本文件旨在供状态监测从业者、工程师和技术人员使用，并提供一种基于振动的实用逐步故障诊断方法。此外，它还提供了一系列机器和部件类型及其相关故障症状的示例。 本文件中给出的方法基于已有的良好实践，由经验丰富的用户总结而成，但也承认存在其他方法。特定诊断的建议措施取决于具体情况、故障诊断的置信度（例如，之前是否正确地对本机器进行了相同的诊断）、从业人员的经验、故障类型和严重性，以及安全和商业考虑。 本文件既不可能也不旨在针对所有情况提出行动建议。

This document sets out guidelines for the specific procedures to be considered when carrying out vibration diagnostics of various types of gas and steam turbines with fluid-film bearings. This document is intended to be used by condition monitoring practitioners, engineers and technicians and provides a practical step-by-step vibration-based approach to fault diagnosis. In addition, it gives examples for a range of machine and component types and their associated fault symptoms. The approach given in this document is based on established good practice, put together by experienced users, although it is acknowledged that other approaches can exist. Recommended actions for a particular diagnosis depend on individual circumstances, the degree of confidence in the fault diagnosis (e.g. has the same diagnosis been made correctly before for this machine), the experience of the practitioner, the fault type and severity as well as on safety and commercial considerations. It is neither possible nor the aim of this document to recommend actions for all circumstances.
