喷灌系统的组成
一个喷灌系统一般由喷头、管网、首部和水源组成。
1.喷头：喷头用于将水分散成水滴，如同降雨一般比较均匀地喷洒在种植区域。
2.管网：其作用是将压力水输送并分配到所需灌溉的种植区域。由不同管径的管道组成，分干管、支管、毛管等，通过各种相应的管件、阀门等设备将各级管道连接成管网系统。现代灌溉系统的管网多采用施工方便、水力学性能良好且不会锈蚀的塑料管道，如PVC 管、PE管等。同时，应根据需要在管网中安装必要的安全装置，如进排气阀、限压阀、泄水阀等。
3.首部：其作用是从水源取水，并对水进行加压、水质处理、肥料注入和系统控制。一般包括动力设备、水泵、过滤器、施肥器、泄压阀、逆止阀、水表、压力表，以及控制设备，如自动灌溉控制器、衡压变频控制装置等。首部设备的，可视系统类型、水源条件及用户要求有所增减。如在利用城市供水系统作为水源的情况下，往往不需要加压水泵。
4.水源：井泉，湖泊、水库，河流及城市供水系统均可作为喷灌水源。在整个生长季节，水源应有可靠的供水。同时，水源水质应满足灌溉水质标准的要求。
Big rain gun has the characteristics of uniform rotation, smooth and reliable operation etc. The spray body and current stabilizer are constructed of aluminum alloy and the accessories are constructed of copper alloy, aluminum, plastics and other corrosion-resistant materials. That improve the corrosion-resistant performance.
Its low-wear design and uniform distribution make it ideal for agricultural irrigation,coal yard, and irrigation or dust fall in Other mining yard.
The versatility and guaranteed reliability of these field-proven sprinklers allows them to be used in a number of different applications.
Design feature:
1, automatic slow rotating mechanical devices to ensure a high degree of uniformity of the dust zone;
2, a special drive power design, providing the perfect atomization dust;
3, the use of special materials and reinforced sealing structure, the longer life;
4, DC-based non-blocking transmission design, spray dust equally well in windy weather;
5, full circle or fan-shaped spray, best meet the needs of a variety of spray operations.
Applications:
Big rain gun are commonly seen at the end of a pivot, on a traveler, or in a Solid Set configuration for irrigating corn, sugar cane, pineapple, or pasture. The big rain gun also works well in environmental applications including reclaimed water distribution, feedlot dust suppression and cooling, mining dust suppression, turf irrigation, and synthetic turf cooling and conditioning.
And their uses keep on expanding as the sprinkler line evolves. Because readily available parts make big rain gun so easy to repair, your sprinklers are assured to be constantly working for you as they stand the test of time.
