Description:
“DTH” is the short for “Down The Hole” and sometimes it is also called “RAB” in some markets, “RAB” is short for “Rotary Air Blasting”.
Usage:
Rotation drill rig, air compressor and the “DTH drill string” are the essential unit for DTH drilling while the “DTH drill string” is always made up of DTH drill rods, DTH hammer and DTH bits. As one of key component, the DTH hammer acts as a role of converting the air pressure to the impact energy, simultaneously transferring impact energy and rotation force to DTH bits.
As specialist manufacturer and provider of DTH drilling tools, hereby we recommend our newest generation DTH hammer which is improved by absorbing art technology, selecting superior alloy steel and robust design. It is proved by more than thousands times of test that our newest DTH hammer has longer life , lower air consumption and 15% higher penetration speed compared the conventional DTH hammer in the market.
Advantage:
1. With longer operating life
2. Excellent anti-wear properties
3. Easy to operate, stable and reliable
4. Smooth with high efficiency
Cautions:
1. Replace all "O" rings, check valve seals and springs inside the submersible impactor, which can ensure the submersible impactor to reduce the air consumption.
2. Ensure that the internal moving parts (piston) of the submersible impactor are well lubricated, and remove all sharp corners and burrs formed by the piston during use (it is recommended to use an oil stone to grind off the sharp corners and burrs of the piston).
3. Ensure that the check valve is clear and returns to the correct position.
4. The outer casing and cylinder should be worn out and replaced in time as needed.
5. Install correctly according to the installation order in the manual or installation schematic.
6. Store properly.
