Great Productivity Water Well Drilling Hammer 1110mm Borehole Drilling Tools
The Characteristics Of High Air Pressure DTH Hammers Without foot valve
It is a kind of high ari 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:
Length(without bit) | Weigth(without bit) | External diameter | Bit Shank | Hole range | Connection Tread | |
1110mm | 66.2kg | φ125mm | Cop54 DHD350R CD55A | φ135-φ155 | API2 3/8" Reg API3 1/2" Reg | |
Working Pressure | Impact rate at 1.5Mpa | Recommended rotation speed | Air consumption | |||
1.0Mpa | 1.8Mpa | 2.4Mpa | ||||
1.0-2.5Mpa | 28HZ | 20-35r/min | 7m³/min | 14m³/min | 19m³/min |
DTH Air Hammer gives you more power down the hole, making your investment produce more in less time. Our DTH hammer is used in many different applications which include but are not limited to heavy construction, mining, oil and gas, quarries, and water-well.
Advantages of high air pressure DTH hammers:
1) Non-Blocking:Our Down the hole hammers are proved to ensure extremely low rate of blocking during it works.
2) High Efficiency:The well drilling equipment carries with larger power of impact frequency and torque, thus ensuring faster penetration. Compared with others, the efficiency can be improved 10%.
3) Longer Service Life:All surfaces of the DTH hammer and bits are treated by anti-friction and intensified technology. When used in deep-hole drilling works, it can reach at 5000 meters or more.
4) Excellent Cleaning Effect: This DTH tool has large air output, which specially designed for water well users and enables it to flush out cuttings in deep hole drilling works.
