摘　　要：通风机是重要的通风设备,基于通风机叶轮叶片的长度变化对通风机性能的影响进行有限元仿真分析。分析结果表明,对叶轮叶片长度进行加长后,通风机的全压及轴功率具有较大的提升,同时全压效率具有较小幅度的下降。在实际应用中,可据此研究对通风机进行改造,以满足相关行业的应用发展需求。Ventilators are important ventilation equipment,and finite element simulation analysis was carried out on the effect of varying the length of ventilator impeller blades on ventilator performance.The results of the analysis show that the full pressure and shaft power of the ventilator have a large increase after the impeller blade length is lengthened,while the full pressure efficiency has a small decrease.In practice,ventilation fans can be modified accordingly to meet the application development needs of the industry.
