Based on the parallel operation experiments of axial-flowfans, moving law of a pair of operation points have been studied.
以轴流风机并联工作实验为基础，研究了通风机并联运行“工况点对”的迁移规律。
2
The operation characteristics of axial-flowfans can be simulated and the gasping vibration can be calculated precisely with the model.
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。

By using the model in real simulator, the operation status of axial-flowfans can be analysed and the results are of specified value to the operation of axial-flowfans in power plants.
