各类旋转机器如汽轮机、电机、燃气轮机、泵、风机、压缩机、齿轮箱、离心分离机等等,广泛运用于国民经济各个部门.近年来,随着水力发电、火力发电、核电及化工等设备的大型化、高速化、轻量化,单机容量不断增加,振动问题日益突出.在工业现场产生的振动现象很复杂,振动原因也多种多样.因此,对工业现场振动故障的诊断、判别是一个很重要的问题.现在仅就旋转机器常见的扳动故障及诊断判别方法作一些介绍。
Various types of rotating machines such as steam turbines, motors, gas turbines, pumps, fans, compressors, gearboxes, centrifuges and so on, are widely used in various sectors of the national economy.In recent years, with hydroelectric power, thermal power, nuclear power and chemical Large-scale equipment, high-speed, lightweight, single-capacity capacity increases, the vibration problem is increasingly prominent in the industrial scene of the vibration phenomenon is very complex, a variety of vibration causes.Therefore, the diagnosis of industrial vibration fault is to determine A very important issue. Now only on the rotating machine common toggle fault and diagnostic methods to make some introduction.
