Scope

Scope: This document specifies the terms and definitions, standardized procedures, inspection and diagnostic methods, fault detection, safety protection, and emergency response plans for rotating machinery fault detection technology. This document applies to rotating equipment fault units operating at a rated speed of no more than 5000 r/min in laboratories and production enterprises. Main technical content: 3. Terminology and definitions 3.1 Fault: A phenomenon in which the equipment "loses its specified function" or endangers safety during operation. 3.2 Rotating machinery: Machines that rely on rotating actions to perform specific functions. Typical rotating machinery includes turbines, gas turbines, centrifugal and axial compressors, fans, pumps, hydraulic turbines, generators, and aero-engines. 3.3 Detection: The process of using suitable detection instruments or comprehensive testing systems to conduct online, continuous measurements of the object being tested in production and experimental environments. 3.4 Fault diagnosis: The process of identifying whether there are faults in the system and equipment through various inspection and testing methods is called fault detection; while the process of further determining the general location of the fault is called fault localization. Fault detection and fault localization both fall under the category of network survivability. The process of isolating the fault to the product level that can be replaced during repair is called fault isolation. Fault diagnosis refers to the process of fault detection and fault isolation. 3.5 Signal processing: The process of processing signals collected from rotating machinery to extract useful information. It is a general term for processes such as extraction, transformation, analysis, and integration of signals. 3.6 Acquisition system: The process of automatically collecting, identifying, and selecting data information from analog and digital units such as sensors and other equipm
