Cambio del Sistema de Enfriamiento de un Motor Diésel Acoplado a una Bomba de Agua

Abstract

 In Camagüey Cuba, 137 deep well water pumping stations, intended for irrigation of tobacco plantations, do not have electrical energy distributed through the rural network; for this reason, it is necessary that the drive units of the pumps be diesel engines. These engines, which are coupled to water pumps, have a radiator and fan to cool the engine coolant. The objective of this work was to evaluate the technical and environmental feasibility of changing the cooling systems of diesel engines coupled to deep well water pumps, with shell and tube heat exchangers. Within the selected exchanger, the pressure losses of the hot water from the engine and the necessary power to maintain recirculation, among other variables, were determined. The savings in diesel fue l and the reduction in CO2 emission to the environment were calculated for 137 water pumps. Changing the cooling system was feasible from a technical and environmental point of view.
