经国家技术监督局批准,国家标准GB11348.1—89《旋转机械转轴径向振动的测量和评定第一部分:总则》于1990年1月1日起实施。该标准提供了测量和评价旋转机械振动特性的一种方法。它适用于确定陆地固定安装的汽轮发电机组、工业汽轮机组和燃汽轮机组等旋转机械振动特性的变化、过大的动载荷及径向间隙监测等方面的问题;适用于测量转轴绝对和相对的径向振动;
Approved by the State Bureau of Technical Supervision, the national standard GB11348.1-89 “Measurement and Assessment of Radial Vibration of Rotating Machinery Shaft Part I: General” was implemented on January 1, 1990. This standard provides a way to measure and evaluate the vibration characteristics of rotating machinery. It is suitable for determining the vibration characteristics of rotating machinery such as turbine units, industrial steam turbines and gas turbines fixed on land, problems of excessive dynamic load and radial clearance monitoring, etc. It is suitable for measuring absolute and relative rotation of shafts Radial vibration;
