Abstract

LA PRESENTE INVENCION SE REFIERE A UN SISTEMA DE BOMBEO MEJORADO CON UN DISPOSITIVO DE MEDICION DEL FLUJO QUE HACE USO DE UNA BOMBA DE DIAFRAGMA AYUDADA CON AIRE CON COMPENSACION DE CARGA. SE UTILIZA UN CONTROLADOR DE LA VELOCIDAD VARIABLE DEL MOTOR PARA COMPENSAR LA REDUCCION DE LA VELOCIDAD DE FLUJO PROVOCADA POR LOS EFECTOS DE LA PRESION. CUANDO LA PRESION DE SALIDA SOBRE LA BOMBA AUMENTA HASTA UN PUNTO DONDE LA CARGA SOBRE EL MOTOR DE LA BOMBA SOBREPASA UN UMBRAL ESPECIFICO, EL CONTROLADOR DE LA VELOCIDAD DEL MOTOR AUMENTA LA VELOCIDAD DEL MOTOR PARA COMPENSAR LAS PERDIDAS DE DISTORSION DEL DIAFRAGMA INDUCIDAS POR LA PRESION Y CONSEGUIR UNA VELOCIDAD DE FLUJO SUSTANCIALMENTE CONSTANTE A TRAVES DE UNA GAMA DE PRESIONES DE SALIDA DE LA BOMBA.
