Underground Water Well Drilling Hammer Durable For Drilling Equipment

Description

When percussion or hammer drilling the percussion mechanism is called a DTH or down the hole hammer. This drilling tool is located directly above the down hole hammer bit. The driller transfers weight to the bit through the drill pipe as well as provides some rotation. Through the use of a compressor, the pressurized air is forced to the down hole hammer. As the drilled hole gets deeper the driller adds more drill pipe to the string. The piston strikes the impact zone of the hammer bit; hammers are always used as part of a casing advancement system and can be used in reverse circulation applications. DTH hammers are common when drilling blast holes and water wells.

Suitable choice of raw material, advanced processing technology and perfect quality warranty.
With hardened treatment, drilling life can be extended and then cost can be reduced.

Applications

Our DTH hammer are widely applied to open pit and underground mining to drill blasting holes, drainage holes, ventilation holes, center holes or blasting holes of raising boring, pipe holes and other deep holesin all various strength rocks, such as quarry exploitation, earthwork projects, water-well, constructionsand so on

Specifications

1. Using the latest rock drilling theory,optimizing the inside structure and the size of the air distrbution,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 designed a safe and reliable anti-shedding device for the bit.

3. The check valve can be replaced to 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.

Feature Advantage

1. Fast drilling speed and low air consumption due to the special inner structure.
2. Smooth performance and long service due to high quality alloy steel materials and advanced processing.

technology adapted

1. Low problem rate and easy to maintenance due to simple, reliable and easy assemble and disassemble inner.

structure of hammer

1. Easy to depart bit from hammer due to multi—head thread connecting chuck and cylinder of hammer.
2. Interchangeable with DTH bit and drill pipe.
