Based on the characteristics of the wells,oils,gas and construction drilling ,our company self-designed,developed and manufactured this kind of high air pressure DTH hammer.
It has the following characteristics:
1.Using the lateset rock drilling theory,optimizing the inside structure and the size of the air distribution,to make the DTH hammer obtain the optimal energy transfer and make it achieve faster drilling speed and lower air condumption.
2.For such projects as the drill bit break,retrieving very difficult,we specailly designed a safe and reliable anti-shedding device for the bit.
3.The check valve can be replaceed to the one with bigger ail controlling hole to provide more efficient cuttings discharge.
