Product Details

Le Kaishan K40 est un trépan à boutons pour marteau fond de trou de la gamme d'outils de forage, servant d'extrémité de coupe du train de tiges DTH dans les roches dures et abrasives. Son corps en acier allié porte des boutons en carbure de tungstène sur une face plate ou convexe, avec une queue cannelée, des trous de chasse et une bague de retenue. L'impact de la queue du marteau DTH traverse les boutons tandis que l'air comprimé évacue les débris, ce qui convient aux travaux miniers, d'extraction en carrière, de forage de puits d'eau et de géothermie. Il s'associe aux marteaux et tiges DTH standard, et Kaishan l'accompagne d'une garantie, d'un support technique, de pièces de rechange et d'une formation des opérateurs.

Working Principle

DTH (Down-The-Hole) drill bits operate at the bottom of the drill string, directly impacting the rock with high-frequency percussion. The bit is connected to a DTH hammer, which is powered by compressed air. The hammer's piston strikes the bit's shank, transmitting energy to the tungsten carbide buttons that crush and fracture the rock. Simultaneously, the bit rotates slowly, allowing the buttons to engage fresh rock surfaces. Compressed air is directed through flushing holes in the bit to lift cuttings to the surface, keeping the hole clean. The K40 bit's design optimizes this process by ensuring efficient energy transfer, uniform button wear, and effective hole cleaning, resulting in high penetration rates and extended service life.
