|Type:||low/middle-low/high air pressure DTH hammer|
|Operating pressure:||5-35 Bar|
|Application:||mining/quarrying/ water well drilling|
1.The strong energy of single impact and the low energy consumption in rock crushing;
2.The weight ratio of Piston and Bit almost Reaches 1:1 to provide long effective acting time, which leads to the improved efficiency in rock crushing and the extended service life of the drilling tool;
3. A good performance in central air exhaust and cuttings discharge, which reduces the repeated crushing of rock;
4.A check valve device is available to drill holes finder water.
Middle-low air pressure DTH hammer(BR1/2/3)
1.The operating air pressures are between 0.7Mpa and 1.75Mpa;
High air pressure DTH hammer without foot valve (DHD/COP/SD/QL/MISSION/NUMA)
1.Out of the trouble of foot valve fracture and expansion and contraction;
2.Lower energy consumption and higher impact frequency. The drilling speed is 15%-30% higher than the one with foot valve;
3.Lower air and oil consumption. The oil consumption is about 10% lower than the one with foot valve.
High air pressure DTH hammer with foot valve (DHD/COP/SD/QL/NUMA)
1.More efficient energy transfer, faster drilling speed, lower air consumption and lower oil consumption;
2.Fewer internal parts, simple structure, longer life, less failure and easier to maintain because all the parts are heat treated;
3.Easy to disassemble because the tap sub, the drive chuck and the external cylinder are connected by multi-step thread.
