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.
