Drip irrigation systems using integrated emitter drip irrigation lines - ELCO are designed for use in vegetable fields, in gardens and vineyards, nurseries, in greenhouses and glasshouses.
Drip irrigation systems with the use of external droppers which are compensated for pressure K4x2.0; К4х2,2; K4x2.5; K2x3 are designed for irrigation and plant nutrition in greenhouses, glasshouses, mushroom pickets, in gardens and vineyards planted on slopes. Uncompanyed by the pressure dropper KS-2 and KS-4 (self-powered), it is advisable to use on private gardens, greenhouses, vineyards, etc. They are designed to work at low pressures, incl. in self-powered systems.
All systems of drip irrigation with their variety of designs and purposes have one common feature - metering channels. Dispensing channels in any system are the most vulnerable elements because they are represented as a zigzag labyrinth that creates turbulent vortices in water passing through them. The cross-sectional area of the various metering channels can be from 0.1 mm2 (for disposable tapes) to 4 mm2 (for external compensated droppers). Integrated pipes and tapes have a direct dependence: the longer the dosing channel, the greater the cross-sectional area it can have. And conversely. The larger the cross-section of the metering channel, the more resistant it is to clogging and salinization.
All drip irrigation systems produced by the plant are assembled as a constructor in the following sequence:
It is used pipes from polyethylene VD in diameter 40 - 75 mm with wall thickness 3,7 - 4,5 mm for distributing pipelines. It is allowed to use a LDPE pipe dia. 32 x 3 mm but the reliability of fastening of the unions of starting or mini-cranes in them reduces.
Feeding pipelines are made of HP polyethylene with a diameter of 16, 20, 22 mm with a wall thickness of 1.8-2.2 mm. Holes are pierced and external droppers are inserted in them, capillaries from which are strengthened with means of tips near plants.
