在进行喷灌作业时,喷头主要用于控制喷洒水流的流向及雾化。流控自动步进喷头是采用射流技术设计成的一种新型喷头,它是利用射流的喷射、卷吸、切换以及动量交换等原理,并采用流控脉冲步进器实现步进回转的自动控制装置。用这种喷头与自吸泵及动力配套丽成的喷灌机具,结构简单,使用方便,可自动换向回转,水力性能良好,能进行各种喷洒作业。
Spray irrigation operation, the nozzle is mainly used to control the flow of spray water and atomization. Flow control automatic stepper nozzle is a new type of nozzle designed by using jet technology. It utilizes the principle of jet injection, entrainment, switching and momentum exchange, and uses the flow control pulse stepper to realize automatic control of stepper rotation Device. With this nozzle and self-priming pump and power Li Cheng irrigation machinery, simple structure, easy to use, can be automatically reversible rotation, hydraulic performance is good, can carry out a variety of spraying operations.
