    This technical project focuses on the design, construction and operation tests of a turbo-pump, which consists of a pelton-type turbine and a diaphragm pump. The project was designed with the purpose of pumping water at high altitudes without the use of electric power or fuel to make the pump works, instead of it; with the use of the potential energy that water acquires in level changes (waterfalls). In the theoretical and analytical part, the diaphragm pump was selected and the pelton turbine was designed according to the operating ranges of the pump like the input power and the revolutions per minute which it works. Besides, the other important parameter for the design is the height that served to determine the flow rate necessary to obtain the input power of the pump and the theoretical speed of the jet exit from the nozzle to the contact with the vanes. The main components: the vanes and the injector were calculated and designed in relation to the jet diameter of the injector nozzle. The machine was built with corrosion-resistant materials such as stainless steel for the structure, impeller, axles and injector, while the vanes used bronze function due to its corrosion resistance, modifiable material and economic cost. During the start-up, the graphs of power vs. flow, revolutions per minute of the turbine vs flow and pumping height vs pumping flow were obtained, those graphs were used to obtain the operating parameters of the turbo-pump.

    Diseño y construcción de una turbo bomba accionada mediante una turbina Michell Banki para riego de cultivos en los sectores vulnerables
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Mecánica, 2018) Coronel Miranda, Christian Omar; Hernández Ortíz, Jhonathan Javier; Mayorga Pardo, Alex Santiago
    Using the parameters of waterfall “Jun Jun” it was possible to obtain a height of 9 meters and a flow of 9 lt/s. These determined the following parameters of the design: the outside diameter of the turbine wheel = 18cm, the appropriate number of blades =20 and the diameter of the pipe to be used = 4 inches. Water flows into the injector, helping propel the rotor blades and movement to the shaft. As a result, mechanical energy is transmitted by means of pulleys and this helps to generate the necessary rotation speed for the pump to work efficiently. With the construction of this machine, the efficiency of the turbine can be calculated with a controlled flow, at a stipulated height and in real conditions. The machine was constructed according to a specific location and to the conditions of this location. In order to work without any problems several changes were made to achieve the most effective design. Performance tests of the turbo pump resulted in the rotation speed provided by the turbine being between 294.56 and 694.02 and a pumping flow from 0.13lt/s to 0.36 lt/s for a height of approximately 30m. These results led to the conclusion that the design of the machine is suitable and reliable to work in the proposed location. This work arises out of the need for electrical energy in the sectors where this service is not currently available. It is an innovative project that favors the development of renewable energies, as there are many areas where they could be implemented greatly benefitting the environment. This project aims to investigate the operation of the turbo pump, which consists of a pump powered by turbine. In our case, the pump is powered by a MICHELLE BANKY turbine.
