喷灌的质量是用良好的机具和合理的系统规划来保证的。通常都是用组合喷灌强度,均匀度和雾化强度三项指标来衡量。从国内外大量研究和生产实践表明,三项指标在很大程度上取决于喷灌系统的布置形式、组合间距和运行方式,但是也都与喷头的水力性能密切相关。因此,在设计系列喷头时,必须在保证机械性能的前提下,尽量改善水力性能。这次联合设计,就是围绕改善水力性能这个中心问题进行的。
The quality of sprinkler irrigation is guaranteed with good equipment and reasonable system planning. Usually the combination of irrigation intensity, uniformity and atomization intensity of the three indicators to measure. A large number of domestic and foreign research and production practices show that the three indicators depend largely on the layout of the sprinkler system, the combination of spacing and mode of operation, but are also closely related to the hydraulic performance of the nozzle. Therefore, in the design of series nozzle, you must ensure that the mechanical properties of the premise, as far as possible to improve the hydraulic performance. This joint design is centered around the central issue of improving hydraulic performance.
