标准摘要
[中文适用范围]： ISO 14839 的这一部分规定了配备主动磁力轴承 (AMB) 的旋转机械的稳定性要求。 它规定了评估稳定裕度的特定指标，并描述了该指标的测量方法。 它适用于额定功率大于15kW的工业旋转机械，不受尺寸或额定运行速度的限制。 它涵盖刚性 AMB 转子和柔性 AMB 转子。 小型转子，例如涡轮分子泵、主轴等，没有涉及。 ISO 14839 的这一部分涉及在内部和/或现场正常稳态运行期间测量的系统稳定性。 内部评估是设备运输的绝对要求，而现场评估的执行则取决于买卖双方的共同协议。 ISO 14839 的这一部分并未解决超过临界速度时出现的共振。 ISO 10814 规定了临界速度下共振的调节。 [外文原描述]： ISO 14839-3:2006 establishes the stability requirements of rotating machinery equipped with active magnetic bearings (AMB). It specifies a particular index to evaluate the stability margin and delineates the measurement of this index. It is applicable to industrial rotating machines operating at nominal power greater than 15 kW, and not limited by size or operational rated speed. It covers both rigid AMB rotors and flexible AMB rotors. Small-scale rotors, such as turbo molecular pumps, spindles, etc., are not addressed. ISO 14839-3:2006 concerns the system stability measured during normal steady-state operation in-house and/or on-site. ISO 14839-3:2006 does not address resonance vibration appearing when passing critical speeds. The regulation of resonance vibration at critical speeds is established in ISO 10814.
