本出版物旨在帮助操作老化旋转设备的人员。本指南概述了一种基于状态的维修方法，用于寻找劣化机制。此外，它还详细说明了适当的定期维修和检查制度，这仍然是识别与年龄相关的故障模式的主要手段。在可能的情况下，描述适当的缓解步骤。本指南的内容由石化、工艺和电力行业的工程师编写。本出版物涵盖的具体设备包括泵、风扇、压缩机、发电机、电机、齿轮箱和某些类型的涡轮机。用户可确定此处未列出的设备适用于EEMUA 230的范围。但是，这是由用户自行决定的。

This Publication has been developed in order to aid those operating ageing rotating equipment. The guide outlines a condition based maintenance methodology for finding deterioration mechanisms. Additionally, it details the appropriate regular service and inspection regime, which is still the principal means of identifying age related modes of failure. Where possible, appropriate mitigation steps are described. The contents of this guide have been written for and by engineers in the petrochemical, process and power industries. The specific equipment covered in the Publication scope are pumps, fans, compressors, generators, motors, gearboxes and certain types of turbine. Users may determine that equipment not listed here is suitable to fall under the scope of EEMUA 230. However, this is done at the user's discretion.
