摘要
设计了一套用于测试风机串联工作时风机之间的气流特性的节流装置,通过试验验证,并绘制出不同阻力挡板在同种流量变化下的性能曲线,流经该装置的气流紊流现象较弱,测量位数值稳定,便于数据采集。为进一步研究风机串联工作时,风机之间的气流特性提供了必要的准备。
A series of throttling device is designed for testing air flow characteristics between fans when they are in series.By experiment verification,the performance curve of different resistance baffles in the same volume changes is drawn,the air flow phenomenon through the device is relatively weak,measured position values are stable,in favor of data collection.It provides the necessary preparations for further study of air flow characteristics between fans when they are in series.
