Abstract
La tecnología para la fabricación de rotores huecos para bombas de Tornillo excéntrico Helicoidal por deformación plástica consiste en la deformación de un tubo mediante la aplicación de una presión interior trasmitida por un fluido ( En nuestro caso Aluminio Fundido) el cual es calentado a una temperatura mayor que su temperatura de fusión, en general el sistema TUBO -Aluminio se calienta a la temperatura de forja del material del tubo. Posteriormente mediante un pistón empujado por un cilindro hidráulico se aplica una fuerza dentro del tubo la cual provoca una presión dentro del mismo, cuando se alcanzan los parámetros óptimos del proceso de deformación, temperatura y presión, se sobrepasa el límite de fluencia y comienza a desarrollarse el proceso de conformación, las deformaciones pasan de elásticas, por lo que el tubo comienza a deformarse plásticamente en dirección radial hasta alcanzar las paredes del molde que tiene una cavidad en forma de tornillo excéntrico helicoidal, obteniéndose de esta forma el rotor hueco.The technology for the manufacture of hollow rotors for Eccentric Helical Screw pumps by plastic deformation consists in the deformation of a tube by means of the application of an internal pressure transmitted by a fluid (in our case Cast Aluminum) which is heated to a higher temperature that its melting temperature, in general the TUBO-Aluminum system is heated to the forging temperature of the tube material. Subsequently, by means of a piston pushed by a hydraulic cylinder, a force is applied inside the tube which causes a pressure inside the tube, when the optimum parameters of the deformation, temperature and pressure process are reached, the creep limit is exceeded and begins to develop the forming process, the deformations pass from elastic, so that the tube begins to deform plastically in a radial direction until reaching the walls of the mold that has a cavity in the form of a helical eccentric screw, thus obtaining the hollow rotor.
