Abstract

LA INVENCION SE REFIERE A UN SISTEMA DE BOMBA PARA PROPORCIONAR Y MANTENER UN FLUJO CONTROLADO DE SALIDA, QUE COMPRENDE UN PAR DE UNIDADES DE PISTONES DE BOMBA (1A, 1B), CON AL MENOS DOS CILINDROS (2A, 2B, 2C, 2D), CADA UNO CON UN PISTON (3A, 3B, 3C, 3D), DISPUESTO DE MANERA DESPLAZABLE EN CADA CILINDRO. COMPRENDE ADEMAS MEDIOS PARA MOVER DE MANERA CONTROLABLE EL PISTON EN CADA CILINDRO, PRINCIPALMENTE MEDIANTE UNA RUEDA EXCENTRICA (15A, 15B, 15C, 15D) PARA CADA UNO DE DICHOS PISTONES, ACTUANDO SOBRE UNO DE SUS EXTREMOS. SE PROPORCIONA TAMBIEN UNA UNIDAD DE CONTROL PARA CAMBIAR DINAMICAMENTE LA VELOCIDAD DE MOVIMIENTO DE DICHOS MEDIOS PARA MOVER EL PISTON, EN RESPUESTA A CAMBIOS DE PRESION EN EL SISTEMA SOBRE EL LADO DE PRESION, PARA MANTENER UN FLUJO DE SALIDA DESEADO DE LA BOMBA. EL SISTEMA DE BOMBA COMPRENDE ADEMAS UNOS MEDIOS VALVULARES (10A, 10B) PARA PROPORCIONAR SOLUCIONES A MEZCLAR, DE ACUERDO CON UNA RELACION PREDETERMINADA, SIENDO CONMUTABLES DICHOS MEDIOS VALVULARES ENTRE CADA FUENTE DE SOLUCIONES (A, B, A , B ). DICHOS MEDIOS VALVULARES ESTAN CONTROLADOS POR UNA UNIDAD DE CONTROL, CON MEDIOS INTEGRADORES, PARA INTEGRAR EL FLUJO DURANTE LA SUCCION DESDE UNA PRIMERA FUENTE DE SOLUCION A MEZCLAR, Y MEDIOS PARA CONMUTAR A OTRA FUENTE DE SOLUCION, CUANDO LA INTEGRACION SE CORRESPONDA CON LA PROPORCION PREDETERMINADA DE LA SOLUCION A SUCCIONAR.
