Mejorar la precision en el diagnostico y pronostico del mantenimiento industrial ha sido una tarea de constante investigacion debido a la necesidad de preservar el continuo funcionamiento de las maquinas de produccion. En el presente trabajo se estudio la bomba centrifuga en estado de cavitacion. Se construyo un banco de pruebas y mediante obstruccion del fluido hacia el rodete del equipo por medio de la valvula de succion, se registraron las senales temporales mediante un acelerometro. Posteriormente, se empleo un estudio no lineal y caotico para representar la geometria en el espacio de fases y su validacion se realizo con el registro de datos de la bomba centrifuga operando sin cavitacion y con maxima eficiencia. Los resultados mostraron que la dinamica del sistema actua de forma no lineal y caotica, representado el fenomeno de cavitacion con una geometria caracteristica. Palabras claves: bomba centrifuga, cavitacion, caos, dinamica no lineal, espacio de fases, serie temporal. ______________________________________________________________________________ Abstract Improving accuracy in the diagnosis and prognosis of industrial maintenance has been a constant task of research to preserve the continuous operation of machines. Today is necessary to improve this technique for avoiding reductionism that the traditional linear techniques employ. In this paper it is studied the centrifugal pump cavitation state. To simulate the phenomenon, a test bed is constructed and the fluid is blocked toward the impeller of pump by the suction valve, the time signals were recorded using an accelerometer. Subsequently, a chaotic nonlinear study was used to represent the geometry in the phase space and validation was performed with the data recording operation of the centrifugal pump without cavitation and with maximum efficiency. The results showed that the system dynamics is non-linear and chaotic, and the cavitation is represented with a characteristic geometry. Key words: centrifugal pump, cavitation, chaos, dynamic nonlinear, phase space, time serie.
