A6210 EMERSON机器设备的健康状态是保障其长期安全可靠运行的基本条件，振动大小是反映机器设备健康状态的主要指标之一。在当前技术水平下，国内外针对大型、重要设备通常都采取了振动监测手段，包括在线或离线监测，通过监测设备的振动判断设备的健康状态。为了描述机器的健康状态，必须根据法定的标准作为评定准则。对于机器设备的制造厂来说，标准是确定产品是否合格的依据；而对于机器设备的使用单位来说，特别是使用中的一些大型设备或流程工业中的关键设备，标准也是随时掌握设备运行状态的依据。国际标准化组织（ISO）下设的振动、冲击与状态监测技术委员会（TC108）是专门负责制定振动与冲击方面国际标准的机构，A6210 EMERSON该机构根据机械设备状态监测和故障诊断技术发展的需要，还归口制定机器状态监测和故障诊断方面的国际标准。我国与ISO/TC 108对口的是全国机械振动、冲击及状态监测标准化技术委员会（SAC/TC53），该委员会由国家有关部委专家共同组成，是全国性专业标准化技术工作组织，由国家质量监督检验检疫总局领导。

用于旋转机械振动评价的主要国际标准有ISO 7919和ISO 10816（有些改为ISO 20816系列）两个系列，分别对应我国国家标准GB/T 11348和GB/T 6075系列标准。这两个系列振动标准简单介绍如下：

1）ISO 10816（GB/T 6075）系列标准主要针对轴承座振动，共有7个部分，如表7-7所示。根据旋转机械轴承座相对于地面的绝对振动（绝对瓦振）进行振动状态评价，主要测量参数是振动速度，评价参数为振动速度值和振动位移值。

2）ISO 7919（GB/T 11348）系列标准主要针对旋转轴振动，共有5个部分，如表2所示。根据支撑轴承处的轴颈相对于轴瓦振动位移（相对轴振）进行振动状态评价。通过安装在轴承附近的电涡流传感器测量相对轴振位移，对振动大小进行评价。

The health of the A6210 EMERSON equipment is the basic condition to ensure its long-term safe and reliable operation, and vibration is one of the main indicators of the health of the equipment. At the current level of technology, vibration monitoring means are usually adopted for large and important equipment at home and abroad, including online or offline monitoring, and the health status of the equipment is judged by the vibration of the monitoring equipment. In order to describe the health state of the machine, it is necessary to use statutory standards as assessment criteria. For the manufacturer of machine equipment, the standard is the basis for determining whether the product is qualified; For the use of machinery and equipment units, especially some large equipment in use or key equipment in the process industry, standards are also the basis for mastering the operating status of equipment at any time. The Technical Committee on Vibration, Shock and Condition Monitoring (TC108) of the International Organization for Standardization (ISO) is the body responsible for the development of international standards on vibration and shock, A6210 EMERSON according to the needs of the development of condition monitoring and fault diagnosis technology of machinery and equipment. International standards for machine condition monitoring and fault diagnosis are also developed centrally. China's counterpart to ISO/TC 108 is the National Mechanical vibration, shock and condition monitoring standardization Technical Committee (SAC/TC53), which is composed of experts from relevant ministries and commissions of the State, is a national professional standardization technical work organization, led by the State General Administration of Quality Supervision, Inspection and Quarantine.

The main international standards used for vibration evaluation of rotating machinery are ISO 7919 and ISO 10816 (some are changed to ISO 20816 series) two series, corresponding to China's national standards GB/T 11348 and GB/T 6075 series standards. The two series of vibration standards are briefly described as follows:

1) ISO 10816 (GB/T 6075) series standards are mainly for bearing seat vibration, a total of 7 parts, as shown in Table 7-7. The vibration state is evaluated according to the absolute vibration of the bearing seat of rotating machinery relative to the ground. The main measurement parameter is vibration velocity, and the evaluation parameter is vibration velocity value and vibration displacement value.

2) ISO 7919 (GB/T 11348) series standards are mainly for rotary shaft vibration, a total of 5 parts, as shown in Table 2. The vibration state is evaluated according to the vibration displacement of the journal at the support bearing relative to the bearing bush (relative shaft vibration). The relative axial vibration displacement is measured by the eddy current sensor installed near the bearing, and the vibration magnitude is evaluated.
