Abstract

Aparato para el control del arranque y paro de una bomba hidráulica. Comprende un detector de caudal (6) que proporciona una señal de paro de la bomba; un detector de presión (5) que presenta una parte móvil asociada a una membrana (14) y una parte fija dispuesta en la carcasa (2) del aparato (1) en la posición de desplazamiento de la parte móvil, presentando también el detector de caudal (6) una parte móvil (9), la cual realiza la función de válvula de cierre, y una parte fija dispuesta en la carcasa (2) del aparato (1), siendo dichas partes fijas sensores magnéticos (12, 13); y medios impulsores (7) del detector de presión (5). Se caracteriza por el hecho de que los sensores magnéticos (12, 13) están conectados de tal modo que si por lo menos uno de dichos sensores abre el circuito (24a) que suministra señal a la bomba hidráulica (1), se produce el paro de la misma. Se consigue un aparato seguro puesto que tiene en cuenta el posible fallo de los sensores magnéticos.Apparatus for controlling the start and stop of a hydraulic pump. It comprises a flow detector (6) that provides a pump stop signal; a pressure detector (5) having a moving part associated with a membrane (14) and a fixed part disposed in the housing (2) of the apparatus (1) in the movement position of the moving part, also presenting the detector flow rate (6) a moving part (9), which performs the function of a shut-off valve, and a fixed part arranged in the housing (2) of the apparatus (1), said fixed parts being magnetic sensors (12, 13); and driving means (7) of the pressure detector (5). It is characterized by the fact that the magnetic sensors (12, 13) are connected in such a way that if at least one of said sensors opens the circuit (24a) that supplies signal to the hydraulic pump (1), the shutdown occurs Of the same. A safe device is achieved since it takes into account the possible failure of the magnetic sensors.
