Product Details

El K46 es un martillo de fondo en la serie de alta presión de aire, la herramienta de clase 4 pulgadas de la línea de herramientas de perforación. El aire comprimido alimentado a través de la tubería de perforación impulsa el pistón, y el sistema de válvulas distribuye el aire para que el pistón golpee el vástago del trépano mientras el flujo de retorno evacua los detritos. La unión superior de acero aleado, el manguito de desgaste y la válvula de retención proporcionan una estructura simple adecuada para roca dura. Se combina con trépanos DTH y tuberías de perforación estándar en equipos rotativos, con el respaldo de la garantía y el soporte técnico de Kaishan.

Working Principle

The Kaishan K46 DTH hammer operates on the principle of converting compressed air into mechanical impact energy. Compressed air is supplied through the drill pipe to the hammer, where it drives the piston in a reciprocating motion. The piston strikes the bit shank, generating a high-energy impact wave that is transmitted to the drill bit. Simultaneously, the air flows through the bit to flush cuttings out of the hole. The hammer's internal valve system controls the air distribution, ensuring smooth and efficient piston movement. The rotation of the drill string indexes the bit, allowing the tungsten carbide buttons to crush the rock in a series of impacts. This combination of impact and rotation enables fast penetration in hard rock. The K46's design minimizes energy loss and maximizes drilling efficiency, making it a reliable tool for demanding applications.
