摘要
通过试验研究了蜗舌与叶轮距离对抽油烟机噪声和性能的影响,表明蜗舌与叶轮距离适当增大时,噪声明显降低,风量和风压有所降低,建议按t/D2=0.05~0.08选择蜗舌与叶轮距离。
Discusses the experiments on how changing of the distance between the volute tongue and the impeller affects noise and performance of the exhaust hood, indicates that when the distance increases properly,the noise decreases apparently and the discharge and pressure also decrease.
