Valveless Down The Hole Drilling Tools 8 Inch With High Efficient Energy Transfer Dth Hammer

In DTH hammers, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH hammers a nearly constant penetration rate regardless of hole length.

The Characteristics of High Air Pressure DTH Hammers With Foot Valve:

It is a kind of valveless high air pressure DTH hammer with foot valve. It has the following advantages:

The main features are as following:

1. Valveless air distribution, more reliable.

2. Simple design of the piston. Long life span.

3. More efficient energy transfer, faster drilling speed, low air consumption and lower oil consumption.

4. Fewer internal parts, simple structure, long life span, less failure and easier to maintain because all the parts are heat treated.

5. Easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multiple steps thread.

The Characteristics of High Air Pressure DTH Hammers Without Foot Valve:

It is a kind of high air pressure DTH hammer without foot valve, and it is our newest design. It is also one of the most advanced DTH hammers in the world.

It has the following 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 span, easy and cheap maintenance.

4. Lower air and oil consumption. The oil consumption is about 10% lower than the one with foot valve.
