High Air Pressure DTH hammer

Release time：2013-12-19

There are two kinds of High Pressure DTH Hammer.High air pressure DTH hammer with foot valve and High air pressure DTH hammer without foot valve,following is the advantage of these two kinds.

1.High Air pressure with foot valve has the following advantages:
-Valved air distribution.More reliable.
-Simple design of the piston,long life.
-More efficient energy transfer,faster drilling speed,low air consumption and low oil comsumption.
-Fewer internal parts,simple structure,longer 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.

2.High Air Pressure without foot valve has the following advantages:
-Out of the troble of foot valve fracture and expansion and contraction.
-Lower energy consumption and higher impact frequency.The drilling speed is 15%-30%higher than the one with foot valve.
-Simple structure,reliable parts,long life,easy and cheap maintenance.
-Lower air and oil consumption,the oild consumption is about 10% lower than the one with foot valve.
