移动管道系统是喷灌专用的管道系统
喷灌设备的管道系统包括固定管道系统和移动管道系统两类。固定管道系统与建筑工地和水利工程使用的管道系统相同,常用有铸铁管、普通钢管、预应力或自应力钢筋混凝土管、石棉水泥管及塑料管等,多数埋设于地下。
The pipeline system of sprinkler irrigation equipment includes fixed pipeline system and mobile pipeline system. The fixed pipeline system is the same as the pipeline system used in the construction site and water conservancy project. There are usually cast iron pipes, ordinary steel pipes, prestressed or self stressing reinforced concrete pipes, asbestos cement pipes and plastic pipes, most of which are buried underground.
移动管道系统是喷灌专用的管道系统,常用镀锌薄壁钢管、铝合金薄壁管和塑料管。镀锌薄壁钢管重量较轻而强度较高,能经受碰撞,防蚀耐磨,使用寿命较长,带有双挂钩球形或其他形式的快速接头,以及S 形连接管、弯管接头、三通、支承架管附件。
Mobile pipeline system is a special pipeline system for sprinkler irrigation, which is commonly used for galvanized thin-walled steel pipe, aluminum alloy thin-walled pipe and plastic pipe. The galvanized thin-walled steel pipe is light in weight and high in strength, which can withstand collision, resist corrosion and wear, and has a long service life. It has double hook ball or other forms of quick joints, as well as S-shaped connecting pipe, elbow joint, tee, and supporting frame pipe accessories.
铝合金薄壁管具有重量轻、强度高、耐腐蚀、使用寿命长、材料能回收等特点,但成本较高,弹性较差,不易修补。配有双挂钩球形、单挂钩承扦式等快速接头及S形连接管、给水栓等成套附件。
Aluminum alloy thin-walled tube has the characteristics of light weight, high strength, corrosion resistance, long service life, material recovery, etc., but it has high cost, poor elasticity and is not easy to repair. Equipped with double hook ball, single hook socket type quick connector and S-shaped connecting pipe, water hydrant and other accessories.
用于喷灌设备的塑料管品种很多,常用的有聚氯乙烯硬(软)管、高压聚乙烯半软管、改性聚丙烯硬管、钙塑聚乙烯硬管、维塑软管等。制造工艺简单,有一定的柔性,可适应地形变化,管壁光滑、耐腐蚀性好,重量轻,使用方便;但易受温度影响及易受紫外线辐射而老化。
There are many kinds of plastic pipes used in sprinkler irrigation equipment, such as PVC rigid (soft) pipe, high-pressure polyethylene half hose, modified polypropylene rigid pipe, calcium plastic polyethylene rigid pipe and maintenance plastic hose. The manufacturing process is simple and flexible, which can adapt to the change of terrain. The pipe wall is smooth, corrosion-resistant, light and easy to use. However, it is easy to be affected by temperature and aging due to ultraviolet radiation.
硬塑料管一般适用于地下埋设的固定管道系统;软塑料管以维塑软管居多,在轻、小型喷灌机上获得广泛应用,其工作压力一般为0.4~0.5兆帕,多采用内转环式或旋扣式快速接头。
The hard plastic pipe is generally suitable for the fixed pipe system buried underground; the soft plastic pipe is mainly the maintenance plastic hose, which is widely used in the light and small sprinkler. Its working pressure is generally 0.4 ~ 0.5MPa, and the inner rotating ring type or screw type quick connector is mostly used.
