Working Principle
The Kaishan K3 DTH hammer operates on the principle of down-the-hole percussive drilling. Compressed air is supplied through the drill string to the hammer, which is located directly above the drill bit. Inside the hammer, a piston reciprocates rapidly, striking the bit shank with high impact energy. The bit then transmits this energy to the rock, causing it to fracture and break. Simultaneously, the exhaust air from the hammer flushes the cuttings out of the hole through the annular space between the drill pipe and the hole wall. The hammer's valveless design simplifies the air distribution mechanism, reducing the number of moving parts and minimizing wear. This results in reliable operation, lower maintenance requirements, and consistent performance even in harsh drilling conditions. The K3 hammer is designed to optimize the balance between impact energy and air consumption, ensuring efficient rock breakage and fast penetration rates.
