均流器均匀送风的实验研究
Experimental study on uniform air supply by flow equalizers
摘要：
应用测压管测压原理，研制了送风均流器，并进行了实体实验。结果显示该均流器能明显改变送风管路特性；均流器均匀送风管路中，风口风量由主风管截面静压和均流器获得的动压转变而成的静压共同决定；均流器均匀送风的距离远大于常规风阀调节均匀送风的送风距离。

Abstract：
Based on the piezometer pressure measuring principle, develops an equalizer for air supply, and performs the experiment on the prototype of the equalizer. The results show that the equalizer can change the characteristics of air supply ducts observably, in the uniform air supply with equalizers, the air rate is determined by the static pressure in main duct and changed from velocity pressure intercepted by equalizers, and the distance of air supply with equalizers is much larger than that with air valve.
