本文件为评估在轴承、轴承座或轴承箱处进行的振动测量提供了指南，也为评估在水力发电和抽水蓄能装置机组上进行的相对轴振动测量提供了指南，当机器在其正常工作范围内运行时。本文件所涵盖的每种类型涡轮机的正常运行范围见附录A。 本文件适用于水力发电厂和典型转速为60 r/min至1000 r/min的抽水蓄能电站中的机组，这些机组配有壳式或瓦（蹄）式油润滑轴承。 注:当前数据库包括60转/分钟到750转/分钟的机器速度（只有1000转/分钟的机器样本）。 本文件定义了轴承箱和轴振动的不同极限值，这取决于涡轮机的类型、轴的方向（i。 e、 水平或垂直）和每个轴承位置。 本文件基于统计分析，为最常见的涡轮机、水泵涡轮机和水泵类型提供了标准。关于本文件中涉及的装置类型的具体信息，请参见附录A。 本文件涵盖的机组可具有以下配置: a） 由水轮机驱动的发电机； b） 由水泵涡轮机驱动的电动发电机； c） 由水轮机和独立泵驱动的电动发电机； d） 由电动机驱动的泵。 本文件不适用于以下机组配置、参数和运行条件: -带有水润滑轴承的液压机； -具有滚动轴承的液压机或机组（这些机器见IEC 62006和/或ISO 10816-3）； -火力发电厂或工业装置中的泵（这些机器见ISO 10816-7）； -作为电机运行的电机，但在泵存储应用中使用这些电机除外； -作为同步冷凝器运行的水轮发电机（涡轮机中的水被压缩空气压下）； -轴承座绝对振动位移的评估； -轴向振动的评估； -瞬态条件的评估； -非同步操作； -评估发电机定子铁芯或定子框架水平的振动。 对水力发电和抽水蓄能装置机组中发生的轴承箱振动和轴振动进行的测量可用于以下目的: 1） 目的A:防止因振动幅度过大而造成损坏； 2） 目的B:监测振动行为的变化，以便进行诊断和/或预测。 这些标准适用于机组本身产生的振动。 需要对从外部源传输到机组的振动进行特别调查，例如通过电站基础传输到机组的振动。

This document provides guidelines for evaluating the vibration measurements made at the bearings, bearing pedestals or bearing housings and also for evaluating relative shaft vibration measurements made on machine sets in hydraulic power generating and pump-storage plants when the machine is operating within its normal operating range. The normal operating ranges for each type of turbine covered by this document are defined in Annex A. This document is applicable to machine sets in hydraulic power generating plants and in pump-storage plants with typical rotational speeds of 60 r/min to 1 000 r/min fitted with shell or pad (shoe) type oil-lubricated bearings. NOTE The current database includes machine speeds ranging from 60 r/min to 750 r/min (with a very small sample of 1 000 r/min machines). This document defines different limit values of bearing housing and shaft vibration depending on the type of turbine, the orientation of the shaft (i.e. horizontal or vertical) and for each of the bearing locations. This document is based on statistical analysis and provides criteria for the most common types of turbines, pump-turbines and pumps. For specific information on which types of units are covered in this document, see Annex A. Machine sets covered by this document can have the following configurations: a) generators driven by hydraulic turbines; b) motor-generators driven by pump-turbines; c) motor-generators driven by hydraulic turbines and separate pumps; d) pumps driven by electric motors. This document is not applicable to the following unit configurations, parameters and operating conditions: — hydraulic machines with water-lubricated bearings; — hydraulic machines or machine sets having rolling element bearings (for these machines, see IEC 62006 and/or ISO 10816？3); — pumps in thermal power plants or industrial installations (for these machines, see ISO 10816？7); — electrical machines operating as motors except for the use of these machines in pump-storage applications; — hydro generators operating as synchronous condensers (with the water in the turbine depressed by compressed air); — assessment of absolute bearing housing vibration displacement; — assessment of axial vibration; — assessment of transient conditions; — non-synchronous operation; — assessment of vibration of the generator stator core or the stator frame level. Measurements made of the bearing housing vibration and shaft vibration occurring in machine sets in hydraulic power generating and pump-storage plants can be used for the following purposes: 1) Purpose A: to prevent damage arising from excessive vibration magnitudes; 2) Purpose B: to monitor changes in vibrational behaviour in order to allow diagnosis and/or prognosis. The criteria are applicable for the vibration produced by the machine set itself. Special investigation is needed for vibration transmitted to the machine set from external sources, e.g. transmitted to the machine via the station foundations.
