Abstract

Un método para controlar la presión de un fluido que se mueve por medio de un generador de presión gobernado por un motor eléctrico en un sistema de tuberías con al menos un consumidor, caracterizado porque: - La velocidad del motor que regula la presión (P) en el sistema de tuberías (1) está controlado por un controlador (9) al cual se introduce al menos una curva de control (R) que corresponde con la presión del fluido en el sistema de tuberías (1), esa presión depende de la cantidad de fluido que fluye o velocidad de fluido (S), y la curva de control discurre uniformemente curvada entre una presión mínima fija y una máxima fija de tal modo que permanece por encima de la línea (G) conectando la presión mínima (P1) y la presión máxima (P2) en la dirección de incremento de presión (P) y está a su más grande distancia del punto medio de la línea que está entre los dos puntos (P1, P2). - El controlador (9) es continuamente alimentado por una cantidad eléctrica proporcional a la cantidad de flujo de fluido o velocidad de fluido (S) como un valor real, y un punto de referencia de la presión (P) que debe ser generado por el generador de presión es determinado desde la cantidad eléctrica usando la curva de control (R) para cada valor real, y - Cuando la presión generada se desvía del punto de referencia de la presión (P) correspondiente a la curva de control, la velocidad del motor está controlada para compensar por ello.
