Abstract

Se trata de un sistema de anti-cavitación eficiente de bombas para ciclos de potencia Rankine orgánicos, consistente en la optimización de la altura neta positiva (o NPSH) disponible a la aspiración de la bomba (4) del ciclo. De este modo, se mejora el funcionamiento de la bomba (4), se alarga su vida útil y se aumenta la eficiencia energética del ciclo de potencia.#Para ello, se requiere de una serie de sensores (7, 8, 9) y un sistema de control (6) que compare las necesidades de la bomba con las condiciones de operación instantáneas y que mediante unos actuadores (5) optimice el funcionamiento del ciclo de potencia.It is an efficient pump anti-cavitation system for organic Rankine power cycles, consisting of the optimization of the positive net height (or NPSH) available at the pump suction (4) of the cycle. In this way, the operation of the pump (4) is improved, its useful life is extended and the energy efficiency of the power cycle is increased. # To do this, a series of sensors (7, 8, 9) and a control system (6) that compares the pump's needs with the instantaneous operating conditions and that by means of actuators (5) optimizes the operation of the power cycle.
