中原50Y 型喷头是与12马力喷灌机配套的、实行单喷头定点作业的双嘴摇臂式喷头,常用工作压力4公斤/平方厘米,流量25立米/小时,射流仰角28度。提高单喷头定点作业机组的喷灌质量,是当前一个比较突出的矛盾,由单喷头作业改为多喷头作业是解决这个矛盾的主要方法,但由于投资和管材等多方面的原因,单喷头定点作业仍然是目前采用的主要作业方式。中原50Y 型喷头水力特性的研究,目的就是为了最大限度地提高大流量喷头的雾化、射程和均匀性。在工作压力不变的条件下,提高大流量喷头的雾化、射程和均匀性,归根到底是选
Central Plains 50Y-type sprinklers are equipped with 12-horsepower irrigation machines, the implementation of single-nozzle fixed-point operation of the double-mouth rocker nozzle, commonly used working pressure 4 kg / cm, flow 25 m / h, jet elevation 28 degrees. To improve the sprinkling quality of single-nozzle fixed-point operation unit is a prominent contradiction at present. Changing from single-nozzle operation to multi-nozzle operation is the main method to solve this contradiction. However, due to various reasons such as investment and pipe, single-nozzle fixed-point operation Is still the main method of operation currently used. Central China 50Y-type nozzle hydraulic characteristics of the study, the purpose is to maximize the atomization of large-flow nozzle, range and uniformity. In the same conditions of work pressure to improve the flow nozzle spray atomization, range and uniformity, in the final analysis
