Although there are many types of sprinkler systems, they can be divided into two categories: unit sprinkler systems and pipe sprinkler systems.The sprinkler system can be divided into light and small units and large and medium units.
Collapsible unit sprinkler system
Sprinkler irrigation system is the sprinkler system of the relevant components assembled into a unit, mobile operation.Its composition is generally the hand lift type or the handcart tractor installs one or more sprinkler head, pump, pipeline, take the motor or the diesel engine as the power, carries on the sprinkling irrigation, its structure is compact, the movement is agile, the mechanical utilization rate is high, can one machine multi-purpose, the unit sprinkler irrigation area investment is low.The light and small sprinkler is a kind of sprinkler system widely used in rural China at present, which is especially suitable for areas with good matching of field channels or wide distribution of water sources and large water intake points.
Folding pipe sprinkler system
Pipeline sprinkler irrigation system refers to the sprinkler irrigation system which is composed of all levels of pipelines.
Folding fully fixed duct type
It is composed of water source, water pump, pipe system and sprinkler head.The components of the sprinkler system are stationary throughout the irrigation season or even year round.The water pump and power machinery are fixed, the dry pipe and branch pipe are mostly buried underground, the sprinkler head is installed on the fixed vertical pipe and can be used in each field in turn.Fixed spray irrigation system operation management and convenient, easy to implement automation control, high production efficiency, but the investment is big, mu investment about 1000 yuan (not including water), vertical pipe has a certain influence on mechanical ploughing and other agricultural operations, equipment utilization rate is low, generally applicable to the economic conditions good irrigation of urban landscape, flowers and grass, or frequent irrigation frequency and high economic benefits of vegetables and fruit orchards, etc., can also be used in ground slope steep hills and make use of the natural water sprinkler irrigation areas use.
Fold fully movable duct
System composed of the same as the stationary, its various parts, water pump, engine, pipe and nozzle, etc are removable, at all levels in more than one field between spraying rotating, so the system of the equipment utilization rate is high, the investment is small, but because of all the equipment (especially the engine and the pump) to remove, carrying, the intensity of labor is big, the production efficiency is low, the equipment maintenance workload is big, sometimes easy to damage crops, generally applicable to the economy is relatively backward area.
Folded semi – stationary pipe type
The system composition is the same as the fixed one, in which the power machine, water pump and water main pipe are fixed all year round or during the entire irrigation season, and the branch pipe, vertical pipe and sprinkler head can be disassembled and moved, and installed in different working positions for rotating sprinkler irrigation.This method integrates the advantages and disadvantages of both fixed and mobile pipe sprinkler systems. The investment is moderate (about 650 yuan to 800 yuan per mu), and the operation and management are also convenient. It is a pipe sprinkler system widely used in China at present.The pipe-type sprinkler irrigation system is more suitable for northern China where water sources are in short supply and water points are few.
