forage de marteau sous-marin pdf

The DTH hammer operates through a system of compressed air. High-pressure air is directed down the drill string, powering the hammer at the end of the drill bit. The hammer strikes the bit with considerable force, fracturing the rock immediately beneath it. As the bit penetrates further, the broken rock is then cleared from the hole by the same air stream, allowing for continuous drilling without the interruptions often associated with other drilling methods.

Rubber-lined pumps are specifically engineered with an inner lining made of high-quality rubber. This lining acts as a protective barrier between the pump components and the fluids being transferred. The primary reason for using rubber as a lining material is its excellent resistance to abrasion, corrosion, and wear. Compared to traditional metal pumps, rubber-lined pumps can significantly extend the lifespan of pump components, reducing maintenance costs and downtime.
