The Down The Hole Hammer is an integral part of the submersible drilling rig and belongs to the working device of the downhole drilling rig. DTH Hammer are divided into low-pressure submersible impacters, stroke pressure dive impacters and high pressure dive impacters.
Widely used in metallurgy, coal, chemical, building materials are not busy mines and water conservancy, hydropower, roads, railways, defense, construction and other projects into the hole, suitable for dry and wet operation hole water wind and water mixture, and borehole gushing wet operation, reliable performance, is now the ideal drilling hole equipment.
It is a kind of high air pressure DTH Hammer without footvalve, our newest design. It is also one of the most advanced DTH Hammers in the world.
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. Simple structure, reliable parts, long life, easy and cheap maintenance.
4. Lower air and oil consumption. The oil consumption is about 10% lower than the one with foot valve.
