Diseño y construcción de una bomba Wirtz para el regadío de pasto en la parroquia Totoras cantón Ambato

Abstract

The need to implement autonomous, efficient, and low-cost irrigation solutions in rural areas led to the development of a WIRTZ-type hydraulic pump for use in the Totoras parish, Ambato canton. This project directly addressed the energy and economic limitations faced by local farmers, offering a sustainable alternative that does not rely on external power sources. The applied methodology was mixed. The qualitative approach involved identifying environmental conditions and user needs, while the quantitative approach focused on collecting and analyzing hydraulic site parameters. The research followed applied, experimental, and descriptive modalities, enabling the design, construction, and functional evaluation of a prototype. The system features a 719 cm³ intake funnel connected to hoses with a gradual reduction from 25.4 to 19 and then to 13 mm, allowing control over fluid velocity. The coil was dimensioned using the relation H ≈ 0.15·L, and the working pressure was determined to be 19.62 kPa. Structural simulations showed minimal displacements in critical components and safety factors greater than 5, validating the robustness of the system. As a result, an operational, stable, and functional pump was obtained, capable of continuously moving water without the need for external energy, positioning itself as a viable and replicable solution for irrigation in agricultural communities with limited resources.
