Big Hole High Air Pressure DTH Hammers
The characteristics of big size DTH hammers using in Water well, oil, gas and construction drilling without foot valve.
Based on the characteristics of the wells, oil, gas and construction drilling, our copmany self-designed, developed and manufactured this kind of high air pressure DTH hammer.
The main features are as following:
1. Using the latest 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 consumption.
2. For such projects as the drill bit break, retrieving very difficult, we specially desighed a safe and reliable anti-shedding device for the bit.
3. The check valve can be replaced to the one with bigger air controlling hole to provide more efficient cutting discharge.
4. The top sub and the drive chuck have special thread, which can achieve an easier disassemble.
