摘要
从气道特性评价方法入手,指出了流量计在发动机气道流动特性研究中的重要作用,通过与孔板流量计作对比试验,证明了旋进流量计在气道流量测试中精度较高,并介绍了旋进流量计在发动机气道流动特性研究中的使用与维护情况。
This paper, which starts with the evaluating methords of gaseous path's characteristics,points out that the flowmeter plays an important role in research on gaseous path's flow characteristics of engine,proves swirl flowmeter has higher precision than orifice plate flowmeter in the contrasting test,and introduces the application and maintenance of swirl flowmeter in research on gaseous path's flow characteristics of engine.
