irrigation system for greenhouse

irrigation system for greenhouse

irrigation system for greenhouse is one of completed fertigation system, also is one of hydroponic system for planting vegetables, flowers, fruits

Irrigation system is one of important and complex system, including main water pipes.  joint , T, control valve , filters etc.

The irrigation system is mainly composed of irrigation pump, pressure regulator valve, controller, filter, field irrigation pipe network and irrigation solenoid valve.  

Pipe network: Its function is to transfer and distribute pressurized water to the planting area for irrigation.  It is composed of pipes of different diameters, which are divided into main pipes, branch pipes and wool pipes. All levels of pipes are connected into a complete pipe network system through various corresponding pipe fittings, valves and other equipment.  The pipe network of modern irrigation system mostly adopts the plastic pipe with convenient construction, good hydraulic properties and no corrosion, such as PVC pipe, PE pipe and so on.  At the same time, necessary safety devices should be installed in the pipe network as required, such as air inlet and exhaust valves, pressure limiting valves, and drainage valves  

Head: its function is to take water from the water source, pressurize the water, treat the water quality, inject fertilizer and control the system.  It generally includes power equipment, water pump, filter, fertilizer, pressure relief valve, check valve, water meter, pressure gauge, and control equipment, such as automatic irrigation controller, constant pressure frequency conversion control device, etc.  The number of the first equipment, the type of visual system, water conditions and user requirements have increased or decreased.  For example, in the case of using urban water supply systems as water sources, pressurized pumps are often not needed.  

Water sources: well springs, lakes, reservoirs, rivers and urban water supply systems can be used as sprinkler irrigation water sources.  There should be a reliable supply of water throughout the growing season.  At the same time, water quality should meet the requirements of irrigation water quality standards.
