Abstract

Sistema principal de servo-actuación de pistón con sistema de actuación de fallos, que comprende dos servo-válvulas (1 y 2), y un pistón (4) unido mecánicamente a un transductor de posición (5). Las servoválvulas (1 y 2) reciben la misma presión desde la línea de alimentación (12) y descargan a la misma línea de retorno (13) y van conectadas al pistón (4) a través de un sistema de canalizaciones (3) para su posicionamiento en función de la demanda eléctrica transmitida por lazos realimentados de control de posición (6 y 7) a los motores de par (8 y 9) de las servo-válvulas, todo ello de modo que si el movimiento del pistón (4) no sigue la demanda solicitada a las servoválvulas (1 y 2), la lógica del sistema detectará la existencia de fallo, realizando el cambio a un sistema de respaldo.Main piston servo-actuation system with fault actuation system, comprising two servo-valves (1 and 2), and a piston (4) mechanically connected to a position transducer (5). The servo valves (1 and 2) receive the same pressure from the supply line (12) and discharge to the same return line (13) and are connected to the piston (4) through a system of pipes (3) for positioning according to the electrical demand transmitted by feedback loops of position control (6 and 7) to the torque motors (8 and 9) of the servo valves, all so that if the movement of the piston (4) does not Following the requested demand of the servo valves (1 and 2), the system logic will detect the existence of a fault, making the change to a backup system.
