摘　　要：本文以某款成熟超高速电风机为研究对象,基于Ansys-CFX仿真平台,建立了电风机系统的数值模拟方法,并深入分析了均压箱内部压力变化情况,电风机内部流场结构及压力损失分布情况,发现电风机内部压力损失主要来自于扩压器以及风道转弯处,压力损失占比高达76.3%。最后,搭建了空气性能试验台对仿真方法进行验证,测试结果表明,真空度和流量实测值与模拟结果符合较好,趋势基本一致,数值误差控制在5%以内,表明本文计算方法可以预测电风机的空气性能。In this paper,a mature ultra-high speed electric fan is taken as the research object,based on the ANSYSCFX simulation platform,the numerical simulation method of electric fan test system is established,and the internal pressure variation of the equalizing box,the flow field structure and pressure loss distribution in the fan are analyzed.It is found that the internal pressure loss of the electric fan mainly comes from the diffuser and the corner of the air duct,accounting for 76.3% of the pressure loss.Finally,the air performance test bench is built to verify the simulation method,indicating that the measured values of vacuum and flow rate are in good agreement with the simulation results,showing a trend similar,and the numerical fault is controlled within 5%,indicating that this method can predict the air performance of the electric fan of vacuum cleaner.
