Abstract

MARTILLO DE PERCUSION HIDRAULICO, EN EL QUE UN MOVIMIENTO DE UN PISTON DE PERCUSION (1) ES CONTROLADO POR UNA VALVULA PRINCIPAL (3), EL MOVIMIENTO DE CONTROL DEL CUAL ES CONTROLADO POR UNA VALVULA DE CONTROL SEPARADA (9) DE TAL FORMA QUE LA VALVULA PRINCIPAL CAMBIA SU ESTADO, CUANDO LA PRESION QUE ACTUA EN LA VALVULA DE CONTROL (9) ALCANZA UN VALOR PREDETERMINADO. EL MARTILLO DE PERCUSION COMPRENDE UN CONTROLADOR (21) MONTADO EN SU CONDUCTO DE RETORNO (13), MEDIANTE EL CUAL PUEDE AJUSTARSE UNA SALIDA DE LIQUIDO DE PRESION DEL MARTILLO DE PERCUSION DE TAL FORMA QUE LA VELOCIDAD DE LLENADO DE UN ACUMULADOR DE PRESION (7) Y POR TANTO LA LONGITUD DE UN MOVIMIENTO DE RETORNO DEL PISTON DE PERCUSION (1) SON PROPORCIONALES A LA RESISTENCIA DE FLUJO PROVISTA POR EL CONTROLADOR (21).
