摘要:
风机的优化改造,对我国工矿企业的节能减排有重大的意义。文章基于通风机气动计算基本理论,针对原多级离心风机吸力不足,效率较差的特点,对其进行优化设计。在制造成本,风机体积等改进限制条件下,通过研究单级的结构和气动性能,分析了叶轮进口气流损失、当量扩张角、预旋、频率共振等因素的影响。经气动复算,结果表明,对叶轮和回流器各增加一片叶片并改变回流器尺寸后,整机压力提高15.3%。
Abstract:
The optimization of fan plays an important role in energy saving and emission reduction of our industrial and mining enterprises. Based on the theory of aerodynamic performance calculation, in view of inadequate suction and poor efficiency of multistage centrifugal blower, the paper carries out aerodynamic optimization design. In the conditions of limiting the cost and volume of the fan, through the analysis of the structure and aerodynamic performance of the single stage, the paper analyzes the impact loss of impeller, equivalent conical angle, pre-rotation, resonance frequency and other factors. The aerodynamic re-count result shows that the pressure increases by 15.3% when a blade is added to the impeller and the return-channel and the return-channel size is changed.
