Product Information:
• Matching for DTH hammer.
• DTH hammer is a part of down hole drilling rig, which is a
working device of down hole drilling rig. Submersible hole impactor
is divided into low air pressure submersible hole impactor, medium
air pressure submersible hole impactor and high air pressure
submersible hole impactor.
Cautions:
The drill bit is a tool for breaking rock, therefore, it is also
the earliest part of the drilling tool to reach its life span.
After each drilling we do, we must carefully check the wear of the
drill bit, respectively.
• See if the drill bit body is seriously worn, if the cylindrical
part of the alloy column leaks out of the drill bit body by 3MM, it
cannot be used further and needs to be sharpened in time.
• The end of the drill bit, that is, the end of the piston of the
submerged hole impactor, the strike depth is more than 1mm, It is
necessary to replace the drill with a new one, because the drilling
efficiency will be seriously affected if the drill is continued to
be used.
Advantages:
• High drilling efficiency, long drilling tool life, submersible
impactor drilling, the medium is air, no flushing media recovery
and disposal problems, reducing the auxiliary time.
• Low cost of use, the submersible impactor requires small shaft
pressure and low speed of the drilling rig, while the torque is
low, so the natural power consumption is small, and the diameter of
the drill pipe is relatively thin, easy to install and disassemble,
and the service life is long.
• Submersible percussion drilling, the hole wall is more complete,
there is no pollution from other media, basically can preserve The
original formation structure and flushing permeability can be
maintained, which reduces washing time and saves costs.
• In severe leakage formations and unstable hole wall formations,
the submerged percussion can be used to follow the pipe drilling to
completely solve the problem of repeated operations.
