Drip Irrigation System – Components and their Function A drip irrigation system consists essentially of mainline, sub mains, lateral, drippers, filters and other small fittings and accessories like valves, pressure regulators, pressure gauge, fertilizer application components etc. Neta can supply a full package for any size or style of irrigation system Neta provides design and planning tools to assist the home gardener with the right selection of irrigation products for their garden. The most common mesh selected for drip irrigation is 100 to 200 meshes (0.15 to 0.08 mm dia). On slopping ground, the laterals are placed along the contour with 1% extra length for sagging purpose. System components are manufactured from quality UV stabilised plastics. The main line conveys the water from filtration system to the sub main. They can withstand the maximum pressure of 2.5 to 4 kg/cm2. Screens filters are specified as below: 1. 10. WHAT ARE THE COMPONENTS OF A DRIP IRRIGATION SYSTEM? With relatively clean water, screen filters can be used alone. The emission device, whether it is drip tape, a drip emitter, jet or micro-sprinkler, then delivers water and nutrients to the soil where plant roots may nourish the plant. Their colour is black to avoid the algae growth and effect of ultra- violet radiation. document.write(''); By the size of holes in the screen (in mm, micron or in mesh i.e. Proper consideration of all aspects at this point, will save time and money later and ensure the system works efficiently and effectively. They are used to close the lateral ends, Submain ends or mainline ends. The large water passage is essential to minimize clogging and provide the minimum discharge for cheapest set-up. The type of filtration needed depends on water quality and emitter type. The design of the system is the most critical component — have the system designed by a qualified and experienced sub-surface drip irrigation designer. They are made up of gunmetal, PVC cast iron and their size ranges from ½” to more than 5”. Drip Irrigation for Onion crop. The flow rate of the filters may be 10,15,20,25,30,40,50 cu/m/hr and the tank diameter may range from 10-50 cm depending on the capacity of the system. It is intended for Netafim's personnel and its representatives and agents all over the globe, and for its clients, their decision makers, managers and operational personnel. medianet_height = "600"; Take off is pressed into the gromate with take of punch upto the step provided. Water enters form the top and flows through the gravel while leaving the dirt in the filter. Gromate acts as a seal. m/hr). The head loss across the filter should not be more than 3 m and otherwise needs cleaning. Pumps. Additional components can be added or excluded depending on the need of the farmer. medianet_width = "160"; Usually they are placed below the ground i.e. By the total surface area of the filter ( in sq. 1. (function() { Components of a Drip Irrigation system. Therefore, an emitter is necessary, ( a hole in a pipe is not a dripper). When the dire accumulates, the pressure difference between the inlet and outlet increase and when the pressure difference is more than 0.5 to 1.o kg/ cm2 ( 5-10 m) , then filters must be cleaned by opening the clover or back washing, Automatic self cleaning filter are also available. The dirt is stopped and accumulated inside the media in the filter. These are used to connect the lateral to Submain. The grooves inside the disc allow the adhesion of fine particles, mainly organic matter. Both sides of the discs are grooved and the grooves cross each other when piled up and frightened together. Other secondary components used to design the … Many parts integrated together form the entire Drip Irrigation system. var mnSrc = (isSSL ? These are installed with or without gravel filter, depending upon quality of water. Filter: It is the heart of drip irrigation. The screens are usually cylindrical shape and are made of non-corrosive metal or plastic material. The main principle when planning a dripper is to achieve the minimum discharge with maximum size of water passage. What sets Neta irrigation apart? The clean water is discharge at the bottom. It is the main component of Drip irrigation system for discharging water from lateral to the soil. Filter: It is the heart of drip irrigation. 4. The sizes are different for 12 mm, 16mm, and 20 mm lateral. A basic Drip Irrigation system consists of a water supply unit, pumping unit, mainline, laterals and emitters. 5. Their discharge range is between 1-15 ph. After cleaning the screen is checked for tears and the gasket should be checked and replaced when necessary. A filter unit cleans the suspended impurities in the irrigation water so as to prevent blockage of holes and passage of drip nozzles. In many cases, the environmental conditions will dictate the choice of emission device for any given application. Their diameter is based on the system flow capacity. A filter unit cleans the suspended impurities in the […]
