HY18 DTH hammer working principle

  1. Drilling bit press against the rock.
  2. High pressure air burst through the check valve from drill pipe, enter the front cavity of hammer.
  3. The increase of the front cavity volume push the piston to move upward.
  4. When the piston moves up to a certain extent, the front cavity deflates and the compressed air enter into the back cavity. Piston keep moving upward because of inertia.
  5. When the piston to a certain extent, due to the compression of the back cavity and the increase of air pressure, the piston starts to impact downward which forming an impact strok. Moves up circles as the above process to achieve impact and complete rock drilling.
