【摘要】：针对现有的单流道旋转微喷头喷洒水量不均匀,旋转喷洒过程中抖动大的不足,研制开发出主流道和副流道为一体的微喷头旋转体,主流道和副流道相向设置。主副流道旋转体中的主流道控制远处的水量,副流道控制近处的水量,大大提高了喷洒的均匀度,同时保证了旋转体的重心处在旋转体转动的中心线上,克服了喷洒转动过程中抖动大的现象。喷洒试验表明,主副流道旋转体在3种喷嘴直径下,流态指数在0.47~0.58之间,为全紊流状态的非压力补偿式。与传统的单流道旋转微喷头相比,主副流道微喷头喷洒效果良好,性能可靠,扩展性强。对提高自主知识产权品牌的市场化占有率具有非常重要的意义。
[Abstract]:Aiming at the shortage of the existing single channel rotating micro sprinkler head with uneven water spraying and the large jitter in the rotating spraying process, a micro sprinkler head rotating body with a main channel and a secondary runner is developed. The main and secondary channels control the water quantity in the distance, and the secondary channel controls the water near the place, which greatly improves the uniformity of spraying. At the same time, the center of gravity of the rotating body is kept on the center of the rotation of the rotating body, which overcomes the phenomenon of the jitter in the process of spraying rotation. The spray test shows that the flow state index of the main and secondary channel rotating body is between 0.470.58 and 0.470.58 under three kinds of nozzle diameters. Compared with the traditional single-channel rotating micro-sprinkler, the main and secondary runner micro-sprinkler has good effect and reliable performance. Expansibility is strong. It is of great significance to improve the market share of independent intellectual property brand.
