基于API617的磁悬浮流体机械振动与稳定性评估
Vibration and Stability Evaluation of Magnetically Suspended Fluid Machinery Based on API 617
摘要
Abstract
To evaluate the design rationality and operation reliability of the magnetically suspended fluid machinery,the API 617 standard was applied to analyze its vibration and stability.Firstly,the relevant specifications and requirements for magnetically suspended fluid machinery in the API 617 standard were introduced.Then,a magnetically suspended blower was taken as the research object,and rotor dynamics analysis,closed-loop transfer function testing,vibration analysis,stability evaluation,and other work were carried out based on the API 617 standard.The results indicate that all indicators meet the API 617 standard requirements.The separation margins between the rotor operating speed and the rigid body critical speed and the first-order bending critical speed are 69.7%and 53.8%,respectively,and the design is reasonable.The modelling of the magnetically suspended rotor system is accurate and can be used to predict the dynamic behavior of the rotor;the peak sensitivity transfer function values of the radial active magnetic bearing(AMB)system are all in zone A,while those of the axial AMB are in zone B,meeting the requirements for long-term and stable operation.The rotor vibration within the operating speed range is less than 10 μm,far below the vibration limit requirement.关键词
