Composition of Sprinkler Irrigation Equipment in Farmland
农业生产中通常采用的灌溉方式主要有地面灌溉、地下灌溉、喷灌、滴灌等四种,其中的喷灌,是通过水泵等把水源处的水以一定压力送到田间,然后通过喷头把水喷向空中,水呈雨滴状散落于地面来浸润土壤,灌溉农田。这几种灌溉方法相比较,喷灌的优点是比较省水,有利于土壤团粒结构的保持,对地形的适应性很强,但缺点是投资比较高,维护要求也比较高。喷灌系统一般由水源、喷灌设备和田间工程组成,喷灌设备又主要由水泵动力机组、输水管道和喷头等部分组成,有些喷灌系统还有行走、控制、量测等设备。
In agricultural production, there are four main irrigation methods: surface irrigation, underground irrigation, sprinkler irrigation, drip irrigation and so on. Sprinkler irrigation is to send water from water www.qiaodongyiyuan.com www.gushanggubing.com www.occiorientedu.com www.haishen56.com www.xingcheng365.com www.cnbdcg.comsource to the field under certain pressure through water pumps, and then spray water into the air through sprinklers. Water droplets scattered on the ground to infiltrate the soil and irrigate the farmland. Compared with these irrigation methods, sprinkler irrigation has the advantages of saving water, maintaining soil aggregate structure, and strong adaptability to topography, but its disadvantages are high investment and high maintenance requirements. Sprinkler irrigation system is generally composed of water source, sprinkler irrigation equipment and field engineering. Sprinkler irrigation equipment is mainly composed of pump power unit, water pipeline and sprinkler head. Some sprinkler irrigation systems also have walking, control, measurement and other equipment.
