标准摘要
[中文适用范围]： 本文件规定了对带有油膜轴承的各种类型的燃气轮机和蒸汽轮机进行振动诊断时要考虑的具体程序的指南。 本文件旨在供状态监测从业人员、工程师和技术人员使用，并提供实用的基于振动的逐步故障诊断方法。 此外，它还提供了一系列机器和组件类型及其相关故障症状的示例。 本文档中给出的方法基于已建立的良好实践，由经验丰富的用户组合而成，尽管人们承认也可以存在其他方法。 针对特定诊断的推荐操作取决于个人情况、故障诊断的置信度（例如，之前是否对该机器正确地进行过相同的诊断）、从业人员的经验、故障类型和严重程度以及安全性和商业考虑。 本文件不可能也没有目的针对所有情况提出建议。 [外文原描述]： 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.
