The torque impact generator of the dth hammer is used in conjunction with the PDC drill bit. The rock breaking mechanism is based on impact crushing and rotating to shear the rock formation. The main function is to ensure the quality of the well body while improving the mechanical drilling speed.The torque impactor eliminates one or more vibration (transverse,
longitudinal and torsional) phenomena that may occur during the movement of the downhole drill bit, keeps the torque of the entire drill string stable and balanced, and cleverly converts the fluid energy of the mud into torsional, high-frequency, uniform and stable mechanical impact energy and transmits it directly to the PDC drill bit, so that the drill bit and the bottom of the well always maintain continuity.
DTH hammer product features：
1) This type of dth hammer is designed with a strong blowing system, which can use all high-pressure gases for slag discharge.；
2) It is designed with an air regulating plug, which can adjust the air used for slag discharge according to the different rock hardness, wear resistance, and drillability to achieve the best slag discharge effect and thus achieve the highest drilling efficiency.；
3) The structure is simple, there are few parts, and the use of wear-resistant parts makes the working time of the dth hammer longer.；
4) The front joint adopts a multi-head thread to connect with the outer cylinder, making it easier for the dth hammer to disassemble the drill bit.
Scope of application of dth hammers：
Mines, quarries, highways and other projects drill blasting holes, barrier holes, mountain reinforcement, anchoring and other engineering holes, geothermal air conditioning holes, water well holes, etc.
When the dth hammer is working normally, the drill bit is against the bottom of the hole, and the dth hammer energy from the piston is directly transmitted to the bottom of the hole through the drill bit.Among them, the cylinder block does not withstand the impact load.When the dth hammer lifts the drilling tool, it does not allow the cylinder block to withstand the impact load. Moreover, the structure is practical and can be achieved by punching.This is because the drill bit and the piston slide down by their own weight for a certain distance, and the air defense perforation is exposed, so the pressure from the alignment mechanism is introduced into the cylinder block, and the central orifice of the drill bit and the piston escapes into the atmosphere, causing the dth hammer to stop working on its own.
