带进气箱的离心风机导流器调节时性能与噪声特性试验研究
Experimental Investigation on Effect of Inlet Box Types on Performance and Acoustic Characteristics of a Centrifugal Fan
摘要
Abstract
The fan performance and acoustic experiments of type 4-73No8D, which is installed with an inlet box with simple guide vane or axial guide vane respectively, are conducted at different guide vane openings, and the performance curves with different inlet boxes at different guide vane openings are compared. The performance investigations show that the inlet box for axial guide vane has a reasonable geometry and better operational performance. And using axial guide vane and simple guide vane can both save power compared with outlet throttle regulation, and the efficiency of the inlet box with axial guide vane is higher than that with simple guide vane. The acoustic results indicate that the fan noise evaluating with A - weight sound level decrease with increasing efficiency, and for the same type of fans, fan noise augments significantly with guide vane opening increasing.关键词
