喷灌是一种比较先进的灌溉方法,具有省水、省地、省力、增产和适应性强的特点。喷灌是利用动力、喷灌泵、管道和喷头将水射到空中,散成水珠进行灌溉的。其原理是:水流由喷嘴射出,冲击摇臂头部挡水板和导水板将摇臂冲开,并扭紧摇臂弹簧。被甩开一定角度的摇臂在弹簧作用下返回,并使挡水板以一定初速度切入水流。挡水板上的臂角使返回速度增加。设计合理的挡水板,避开了水舌的冲击,获得很大功能的摇臂,撞击喷头正旋一个角度,摇臂进入起点,开
Sprinkler irrigation is a more advanced method of irrigation, with the characteristics of saving water, saving land, saving labor, increasing production and adaptability. Sprinkler irrigation is the use of power, irrigation pumps, pipes and nozzles to shoot water into the air, dispersed into water droplets for irrigation. The principle is: the water jet from the nozzle, the impact of rocker head flap and water guide plate to open the rocker arm, and tighten the rocker arm spring. The rocker, which is thrown away at a certain angle, returns under the action of a spring and cuts the flap into the water at a certain initial velocity. The arm angle on the flap increases the return speed. Well-designed flap, to avoid the impact of the water tongue, access to great features of the rocker, impact sprinklers are rotating an angle, the rocker into the starting point, open
