Abstract

INSTALACION DE PROPULSION ELECTROHIDRAULICA. UNA BOMBA (16) DE DESPLAZAMIENTO VARIABLE PROPORCIONA FLUIDO A PRESION A UN MOTOR DE FLUIDO (40) A TRAVES DE UN ORIFICIO VARIABLE (44), UNA VALVULA DE CONTROL DIRECCIONAL (24) Y UN PASO. UN SOLO TRANSDUCTOR DE PRESION (48) GENERA UNA SEÑAL DE PRESION (VP) ELECTRICA QUE REPRESENTA LA PRESION EN EL PASO AGUAS ABAJO DEL ORIFICIO. UN CIRCUITO DE CONTROL GENERA UNA SEÑAL DE CONTROL (VC) MODULADA EN ANCHURA DE IMPULSOS CON UN CICLO DE SERVICIO QUE VARIA EN FUNCION DE LA SEÑAL DE PRESION Y UN VOLTAJE DE REFERENCIA FIJO. UNA VALVULA (64) MANIOBRADA POR SOLENOIDE CONTROLA UNA VALVULA DE CONTROL DE CARRERA (26) MANIOBRADA POR PILOTO EN RESPUESTA A LA SEÑAL DE CONTROL. LA VALVULA DE CONTROL DE CARRERA AJUSTA EL DESPLAZAMIENTO DE LA BOMBA (16) PARA MANTENER UNA DIFERENCIA DE PRESION CONSTANTE ENTRE LA PRESION DE SALIDA DE LA BOMBA Y LA PRESION PERCIBIDA CUANDO ESTA ABIERTA LA VALVULA DE CONTROL DIRECCIONAL.
