M6A DTH Hammer (M6)
Mission 60 Down The Hole Hammer
M 6A DTH Hammer Mission 60 Down The Hole Hammer for Submersible Drilling Rig
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.
The working principle of the impact: the beginning of the impact of the stroke, the piston and the valve are in the extreme position, the pressure through the valve cover and the seat of the radial hole into the cylinder chamber, pushing the piston high-speed downward movement impact drill. When the piston row to the bushing of the spline groove is closed, the lower chamber pressure began to rise, so the upper end of the piston hole out of the air column, so that the upper cavity through the atmosphere, the pressure is reduced, the end of the working stroke. When the piston after the impact of the tail of the drill, the valve due to its upper and lower pressure effect, the commutation, the piston repeated return stroke movement.

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.
It has the following advantages:
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.
