Item Diseño y construcción de un prototipo de turbina tipo tornillo sin fin para la iluminación y electrificación de cercados eléctricos en las comunidades y sectores rurales del cantón Latacunga(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2024-07) Guilcamaigua Chacon, Bryan Steeven; Yunapanta Velastegui, José LuisDue to the need to improve the energy supply in the rural sectors of the Latacunga canton, it is proposed to carry out the respective design, improving the quality of life of the inhabitants of the sector. In this research, the data obtained from the water channel of the Anrracas sector in the parish of Juan Montalvo in the city of Latacunga were used, taking into account as important data the value obtained from the water flow, the design and mechanical construction of the Archimedes screw type turbine prototype was elaborated, for the realization of this project several scientific articles and investigative documents referring to the subject were used. The construction of the design was made based on the data of the flow of the channel, for this a previous sketch was made in a 3D software simulator of mechanical design, for the proper functioning of the screw in the water was considered an average flow of 0.5 to 1.5 cubic meters per second. The materials for the construction and assembly of the prototype were selected after the analysis of the weight of the screw, dimensions, resistance of the structure, the materials selected for the assembly of both the structure and the turbine are corrosive materials because the turbine prototype will be submerged in water. Once the operation tests were carried out with a multimeter, the voltage measurement was taken, resulting in 13.5 V, and 550 rpm, with the values obtained led lamps were turned on, obtaining an optimal result for the project's functionality.Item Diseño y construcción de un sistema para mantener el caudal constante a la entrada de una turbobomba(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2021-06) Soto Andino, Elvis Geovanny; Carrillo Rosero, Carlos MauricioTechnical project was developed because of the importance of incorporating a system to monitor and control the flow at the inlet of a Pelton turbine turbopump in real time from a specific control point. This system will allow a real flow to be leveled through a motorized valve at any base flow that is within the opening range and keep it constant. The control program was developed in the LabWIEW software, from this program the system could be controlled. For the operation, essential data was provided such as: base flow rate, initial valve opening and run times, the program recorded the data entry in real time, processed and executed the action of opening or closing the valve by energy pulses. The data taken from flow and revolutions jointly with the time data and valve opening percentage generated by the program in each time interval, an Excel file will be stored and exported at the end of the assay. An ultrasonic flowmeter was used to measure and record the flow rate value in the pipeline, these data are sent via Wifi signal to the control point and a Hall sensor to record the revolutions (rpm) on the turbine shaft. The valve takes between 130 and 170 seconds to level to the desired Flow, the installation and operation tests of the equipment were carried out in the "Cal y Piedra" waterfall located in the Mocha Canton.
