低压旋涡风机进气口的实验研究

摘要

通过实验，分析了不同进气口面积对低压旋涡风机性能 的影响。实验结果表明，适当增大进气口面积，可提高风机的效率并扩大流量范围。%Based on the experiment of a low-pressrue vortex blower, the influence of the di fferent blower inlet area on its performance has been investigated. The experime nt results show that the total efficiency and the flowrate are improved with the increase of blower inlet area.
