- 摘要:
- 以30 PSH喷头为例，用正交方法分析了喷头的组合系数、工作压力、布置形式对喷灌均匀系数影响的强弱顺序，其顺序为：组合系数对均匀系数的影响要大于工作压力，而工作压力对均匀系数的影响又大于布置形式。以及采用等腰三角形，组合系数为1.2 R，工作压力为0.3 MPa左右时能达到最佳的均匀系数。这些结论对喷灌工程设计有非常重要的指导意义。
- Abstract:
- Taking the sprinkler head of 30PSH as an example, the method of perpendicularity is used to analyze the influence of combination distance, work pressure and layout form on uniformity coefficient in irrigation.The effect sequence is that combination distance is stronger than work pressure, and then is layout form. When the isosceles triangle layout is applied, combination distance is 1.2 R and work pressure is 0.35 MPa, then the best uniformity coefficient will be got. These conclusions have very important guidance meaning to the engineering design of irrigation.
