Resumen
El sistema de abasto Ochoíta es una de las principales fuentes que garantizan el abastecimiento de agua potable a la ciudad de Santa Clara, por lo que es necesario asegurar un funcionamiento adecuado de los diferentes objetos de obra que lo componen, para garantizar un mejor servicio de acueducto a la ciudad. El sistema de abasto parte de la fuente, constituida por aguas superficiales de la presa Minerva ubicada a 17km de la ciudad, la planta potabilizadora con una estación de bombeo, ubicada dentro de la misma instalación con capacidad de impulsión de 630 L/s, mediante la cual se impulsa el agua tratada hasta una chimenea de equilibrio ubicada en la Loma Dos Hermanas a través de una conductora de diámetro variable. El presente trabajo consiste en la elaboración de un modelo hidráulico, capaz de simular el comportamiento hidráulico actual de la conductora Ochoíta - Dos Hermanas y en específico lo referente a caudales, velocidades y presiones mediante el empleo del software WaterCAD V8 con el objetivo de comprobar la funcionalidad y compatibilidad de determinados dispositivos de protección para el Golpe de Ariete que pudiera producirse en la instalación bajo determinadas consecuencias. El análisis se realiza primeramente para el sistema sin protección y posteriormente se analiza el sistema considerando los dispositivos necesarios para garantizar una protección ante la ocurrencia del Golpe de Ariete.
The water supply system ¨Ochoita¨ is one of the principal sources of water supply for Santa Clara city, for which it is necessary to assure the well-functioning of different objects which form a system, to guaranties the best service of potable water. The water system is composed of, surface water from the dam ¨Minerva¨ located 17km from the town, water treatment plant together with a pump station with the capacity impulsion flow of 630L/s, through the impulsion of treated water until the tank on top of the hill, ¨Dos Hermanas¨ through a pipe with variable diameters. The present thesis consists in elaborating a hydraulic model, able to simulate the actual hydraulic behavior of the water pipe ¨Ochoita-Dos Hermanas¨ and in specific referring to the water flow, velocities and pressures through the software WaterCAD V8 with the objective of testing the functionality and the compatibility of protection apparatus from a hydraulic transient, which might occur in the installation through certain consequences. The analysis is first run when the system is unprotected then later analyzing the system considering the necessary apparatus to guaranties the protection before the event.
