--High air pressure DTH hammer: DHD 340. DHD 350, DHD 360, DHD380 N125 SD12etc.
Features:
1.valveless air distribution. More reliable.
2.simple design of the piston, long life.
3.More efficient energy transfer, faster drilling speed, lower air consumption and lower oil consumption.
4.fewer internal parts, simple structure, longer life, less failure and easier to maintain becayse all the parts are heat treated.
5. It is easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi-step thread.
Applications:
widely used for produce large-diameter holes in rocks for water-well.oill-field,coal-Mines, tunnels, quarrying and roads, power stations,and other construction projects.it is suitable for very hard and abrasive rock formation,medium-hard and homogeneous formation.soft rock and fissured rock formations etc.
