Alloy Steel Revirse Circulation RC Hammer And Down The Hole DTH Hammer

Alloy Steel Revirse Circulation RC Hammer And Down The Hole DTH Hammer


Product description


DTH drilling tool is a kind of drilling system which uses compressed air as motivation, makes drilling impact motivation parts down the hole, to control the piston reciprocating motion by the distribution device in the hammer, and then impacts the DTH bit in the front of the hammer to transit the impacting power to the bit. The DTH bit in the front of the hammer breaks the rock to drill hole.


Reverse Circulation hammer (RC hammer) is our most advanced product, used in deep hole exploration drilling and mining ore grade control, etc.

Product features


DTH hammer features:

-Valveless air distribution. More reliable.
-Simple design of the piston. Long life.
-More efficient energy transfer, fact drilling speed, lower air consumption and lower oil consumption.
-Fewer internal parts, simple structure, long life, less failure and easier to maintain because all the parts are heat treated.
-Easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi-step thread.


RC hammer features:

-Reference the design and production experience of conventional DTH hammer and combine the operating characteristics of RC hammer; internal structure design is optimized to ensure ideal energy transfer and high drilling speed as well as steady sampling.
- Simple internal structure and rigid components ensure long using life and easy maintenance of the hammer.
- Sample tube is integrative designed and can be placed without disassembling of the hammer. With carburizing treatment, the sample tube has good wear resistance.
- RC bit has patented design. One hammer could drill different size of holes just by replacing different size bits, and ensure no contamination of the sample as well.
- In difficult conditions such as loose soil, hard rock formation or plenty of water exists, sampling can be done well.


Application


At present, DTH and RC drilling tool is widely used in underground mining, quarries, hydraulic and Hydro-Power Engineering, water well drilling, Mineral exploration, anchoring hole drilling, geothermal engineering, Subway excavation, another civil engineering.
