喷灌设备的管道系统
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. Fixed pipeline system is the same as the pipeline system used in construction sites and water conservancy projects. Cast iron pipes, common steel pipes, pre-stressed or self-stressed reinforced concrete pipes, asbestos cement pipes and plastic pipes are commonly used. Most of them 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 piping system is a special piping system for sprinkler irrigation. Galvanized thin-walled pipes, aluminum alloy thin-walled pipes and plastic pipes are commonly used. Galvanized thin-walled steel pipe has lighter weight and higher strength, can withstand collision, corrosion and wear resistance, longer service life, with double hook spherical or other forms of fast joints, as well as S-shaped connecting pipe, elbow joint, tee, support 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 and material recycling, but it has high cost, poor elasticity and is not easy to repair. It is equipped with double hook spherical, single hook bearing cutter and other fast joints, S-shaped connecting pipe, water hydrant and other complete sets of 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 hard (soft) pipes, high-pressure polyethylene semi-hoses, modified polypropylene hard pipes, calcium-plastic polyethylene hard pipes and vinyl plastic hoses. The manufacturing process is simple, flexible, adaptable to terrain change, smooth pipe wall, good corrosion resistance, light weight, easy to use, but vulnerable to temperature and ultraviolet radiation and aging.
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。
Hard plastic pipes are generally suitable for fixed pipeline systems buried underground. Soft plastic pipes are mostly plastic hoses, which are widely used in light and small sprinkler irrigation machines. Their working pressure is generally 0.4-0.5 MPa, and they mostly use inner-rotating ring or screw-fastening fast joints.
