Diseño y fabricación de un micro aspersor con una presión de trabajo entre 10 A 30 PSI para un sistema de riego en cultivos de pera de la parroquia Huachi Grande

Abstract

The aim of this project is to design and manufacture a micro sprinkler for crop´s pear that is capable of supplying with the water needs of the crop and at the same time avoid clogging in the nozzle. For the development of the project was carried out an analysis of the current state of the geometry of a micro sprinkler in the market to take into account the parameters from which the study. Followed by this identifies the location of the land, the crop´s characteristics and tests are performed to know what type of land is worked. Afterwards, TDS and pH tests are performed on the irrigation water to determine particle sizes that can clog the nozzle of the micro sprinkler. Next, we performed agronomic and hydraulic calculations that served to design different models with variations in their geometries specifically the orifice diameter and the surface angle of the impact of the jet; A 3D printer was used to obtain the micro sprinklers and CFD software analyzed velocity behaviors which were checked in a test bench and allowed to determine the spray range and area of coverage of the spray and quality of the same.
