, Water source project
The water source of the drip irrigation system can be wells, springs, reservoirs, channels, rivers, lakes, ponds, etc. But the water quality must meet the irrigation water quality requirements. The water source project of the drip irrigation system generally refers to the water blocking, water diversion, water storage, water lifting and sedimentation projects built to draw water from the water source for drip irrigation, as well as the corresponding power transmission and distribution projects.
, first hub
The first hub of the drip irrigation system includes a power machine, a water pump, a fertilizer (medicine) device, a filtering facility, and safety protection and measurement control equipment. Its function is to take water from the water source, pressurize it, inject fertilizer (pesticides), filter it, and transport it into the pipe network on time and in quantity. It is responsible for the driving, measurement and regulation tasks of the entire system, and is the control and deployment center of the entire system.
Commonly used water pumps for drip irrigation include submersible pumps, centrifugal pumps, deep well pumps, pipeline pumps, etc. The function of water pumps is to pressurize the water flow to the pressure required by the system and transport it to the water pipeline network. The power machine can be an electric motor, a diesel engine, etc. If the natural head of the water source (water tower, high-level pool, pressure water pipe) meets the pressure requirements of the drip irrigation system, the water pump and power can be omitted. The filtration equipment filters the water flow to prevent various dirt from entering the drip irrigation system and clogging the drippers or forming sediment in the system. Filtration equipment includes dirt racks, centrifugal filters, sand and gravel filters, screen filters, laminated filters, etc. When the water source is a water source with poor water quality such as rivers and reservoirs, a sedimentation tank needs to be built.
The function of the fertilization device is to fully dissolve fertilizers, pesticides, herbicides, chemical control chemicals, etc. that are easily soluble in water and suitable for root application in the fertilization tank, and then transport them to the roots of the crops through the drip irrigation system.
Flow and pressure measuring instruments are generally used to measure flow and pressure in pipelines, including pressure gauges, water meters, etc. Safety protection devices are used to ensure that the system works within the specified pressure range to eliminate air resistance and vacuum in the pipeline. They generally include controllers, sensors, solenoid valves, water valves, air valves, etc. Regulatory control devices generally include various valves such as gate valves, ball valves, butterfly valves, etc. Their function is to control and regulate the flow and pressure of the drip irrigation system.
, Water transmission and distribution pipe network
The function of the water transmission and distribution pipe network is to transport and distribute the water flow processed by the first hub to each irrigation unit and dripper according to the requirements, including main pipes, branch pipes, capillary pipes and the required Connect pipe fittings and control and regulating equipment. Due to the size of the drip irrigation system and the layout of the pipe network, the grade classification of the pipe network is also different.
, dripper
The dripper is the most critical component of the drip irrigation system and is a device that directly applies water and fertilizer to crops. Its function is to use the tiny flow channels or holes of the dripper to dissipate energy and reduce pressure to turn the water flow into water droplets and evenly apply them to the soil in the root zone of the crop.
