Mission series DTH hammer
Mission series of high pressure wind tunnel DTH hammer without nylon tube
Model：Mission40/Mission50/Mission60/Mission80
Down-hole impactor is a part of a down-hole drilling rig and belongs to the working equipment of a down-hole drilling rig.Down-hole impactor is divided into low-pressure down-hole impactor, stroke pressure down-hole impactor and high-pressure down-hole impactor. The drill equipped with high-pressure non-nylon tube DTH hammer is my company designed valveless high-pressure impactor, is currently the world‘s most advanced one of the impactor.
It has following advantages:
1.Out of the trouble of foot valve fracture 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 span,easy and cheap maintenance.
4.Lower air and oil consumption.The oil consumption is about 10% lower than the one with foot valve.
Impactor Applications:
Widely used in metallurgy, coal, chemical industry, building materials are not busy mine and water conservancy, hydropower, roads, railways, national defense, construction and other projects into holes, apply to dry, feng shui mixing and gushing blasting wet work, reliable performance , Is today‘s ideal drilling drilling equipment.
