High Air Pressure Without Foot Vlave DTH Drill Hammer Ql60A
High Air Pressure Without Foot Vlave DTH Drill Hammer Ql60A For Down Hole Hammer Drilling
Down The hole hammer:
High pressure Down The hole hammer
Roschen has middle pressure, high pressure down the hole hammer, which is a true high-speed, high-efficiency down the hole hammer application of modern design theory, through computer simulation, design of high efficiency, high life, low consumption submersible impact ;
High wind pressure (0.56-2.46Mpa) into high impact energy, in order to achieve unprecedented high perforation speed; due to the simple structure, improve component life and reduce maintenance workload and maintenance costs.

Description:
High air pressure DTH Hammer without footvalve, which has been one of the most advanced DTH Hammers in the world is our own design.
Advantages:
1. Out of the trouble of foot valve fracture and expansion and contraction.
2. Lower energy consumption and higher impact frequency. The drilling speed is 15%-30% higher than the one with foot valve.
3. Simple structure, reliable parts, long life, easy and cheap maintenance.
4. Lower air and oil consumption. The oil consumption is about 10% lower than the one with foot valve.
