摘要
本文针对我国农田灌溉中使用的梯形渠道机翼形量水槽,通过对其测流原理、基本结构的分析,结合运行过程中实时采集数据,对其应用测流性能和实际运行效果进行分析研究。通过试验数据分析,机翼形量水槽实际应用时满足应用条件且精度符合量水规范要求。进一步研究,得到了其应用时的一些性能参数指标,表明其灵敏度较高且连续性较好,在目前的灌区现代化管理中基本适用。
In view of the use of irrigation channels trapezoidal wing shape measuring flume,through its flow measurement principle,the basic structure of the analysis,the process of combining real-time data collection run its application flow measurement performance and actual operating results are analyzed.By analyzing test data,the wing-shaped measuring flume meet the application conditions and the practical application of precision in line with the amount of water specifications.Further studies give some indicators of its performance pa- rameters when applied,indicating a high sensitivity and good continuity in the current management of irrigation modernization in generally applicable.
