摘要
对轴流风机和离心风机的运行特性进行了详细的分析和比较,首次提出了轴流风机的实时仿真模型。该模型能够真实地反映出轴流风机的运行特性,并能准确地计算出轴流风机的喘振工况。在实际仿真机上应用该模型,可以分析出两台轴流风机并列运行时的喘振工况,对现场轴流风机的运行具有一定的指导作用。
In this paper, the performance curves of axial-flow fans and centrifugal fans are analysed and compared, and the real-time simulation model of axial-flow fans is established. The operation characteristics of axial-flow fans can be simulated and the gasping vibration can be calculated precisely with the model. By using the model in real simulator, the operation status of axial-flow fans can be analysed and the results are of specified value to the operation of axial-flow fans in power plants.
