摘要
利用GB/T1236-2000标准中规定的A型进气风室研究在小流量区域内测试离心和轴流通风机流通特性时,其流场的分布以及在静压测试中出现的问题。通过实验发现在离心风机测量截面上静压存在波动,轴流风机静压沿着径向分布存在差别,分析影响其静压分布的因素并提出相应的对策。
In this paper,the flow field distribution and the issues occurred in static pressure measuring for A type air inlet chamber which conforms to GB/T 1236-2000 are studied when testing the characteristics of centrifugal fan and axial-flow fan within the small flowrate area.The test result shows that the static pressure has fluctuation on the measuring section of centrifugal fan and the distribution of static pressure along radial direction has differences in axial-flow fan.The factors affecting the distribution of static pressure are analyzed and the corresponding countermeasures are pointed out.
