Abstract

ARIETE HIDRAULICO DE PERFORACION AUTOPROPULSADO Y REVERSIBLE EN EL QUE LA SELECCION DE LOS MODOS AVANCE/RETROCESO SE DETERMINA POR LA POSICION DE UN PISTON DE CONTROL (3). SE CONECTA A LA ENTRADA DE FLUIDO DE FORMA COAXIAL (9,10) UNA TUBERIA CONCENTRICA DE ALIMENTACION DESDE UNA FUENTE DE PRESION PARA EL FLUIDO DE TRABAJO. LA PRESION DEL FLUIDO PARA EL PISTON DE IMPACTO (2) (MARTILLO) SE SUMINISTRA A TRAVES DE LA ENTRADA (10). EN EL MODO DE AVANCE SE SUPERA LA PRESION EJERCIDA POR UN MUELLE HELICOIDAL (7) Y LA FUERZA DE REACCION DEL PISTON (3) MEDIANTE LA PRESION DEL FLUIDO DE TRABAJO EN LOS PISTONES AUXILIARES (5,6 Y 8). EL COSTE DE LA PRESION DEL FLUIDO HACIA LOS PISTONES (5 Y 6) PERMITE AL PISTON (3) MOVERSE EN EL MODO DE RETROCESO.
