The down-the-hole hammer is a new type valveless hammer driven by compress air.It is the ideal rock drillling tool with advages of large impact energy,high penetration rate,long service life,good efficiency of drilling cuttings removal,easy operation,reliable working performance and so on.

TH----for wet drilling
Wadely applied to all kinds of rock boring hole drilling and excellent in projects for casing system and water well drilling.
Can be matched to various types of hammers popular in the world and drill the holes from 76mm to 1200mm in diameter.

TS----for deep hole and super deep hole drilling
Can be meet to the needs of drilling holes from 203mm to 660mm in diameters.

TG----for drying drilling
Have stable performance, fast speed, long service life in sleeves, and 10% less air consumption than other ordinary hammers, and can also work well without the foot valves.
Drill holes from 90mm to 254mm.

All our Hammers can be easily adapted to accept different types of bit shanks as COP, BR, DHD, SD, XL QL, MACH, Halco and Mission by simply changing a few basic components. Several models are available in Heavy-Duty format to suit particularly arduous and abrasive drilling conditions.

JFC-5 Tractor Mounted Reverse Circulation Water Well Drilling Rig

1.Introduction of JFC-5 Tractor Mounted Reverse Circulation Water Well Drilling Rig
The rotary water well drilling rig with reverse circulation well washing medium is referred to as reverse circulation drilling rig. Its core lies in the unique "reverse circulation" working mode. The drilling fluid naturally flows into the annular gap between the drill pipe and the well wall directly to the bottom of the well, and then carries the cut drill cuttings back to the wellhead through the inner cavity of the drill pipe, and is discharged to the water supply pool through the faucet and the slag discharge pipe, and is recycled after sedimentation and clarification. This "outside down and inside up" circulation method is particularly good at handling large-diameter drilling operations in complex formations such as pebbles and gravel, and has achieved efficient slag discharge capabilities far exceeding traditional drilling rigs. It is mainly used in the fields of water well drilling and engineering bored pile drilling.â??
2. Features of JFC-5 Tractor Mounted Reverse Circulation Water Well Drilling Rig
2.1 With the tractor as the carrier, the mechanical structure technology is mature and the performance is stable.
2.2 The tractor chassis has all-terrain off-road capabilities and can be easily moved to other locations in complex terrains such as muddy fields, rugged hillsides, and narrow country roads.
2.3 The mud pump has strong suction, high rising flow rate, and strong pipeline slag discharge capacity. It can continuously and quickly discharge the cut drilling slag or pebbles out of the hole, reducing the number of repeated cutting or grinding and significantly improving the construction speed.
2.4 Equipped with hydraulic outriggers to level the drilling rig and ensure the stability of the machine body.
2.5 The well drilling rig is equipped with a generator in front, which is easy to switch between diesel and electricity.
2.6 The operating handle and distribution box are compactly and reasonably arranged for easy operation.
2.7 Equipped with a 5-speed gearbox, it can meet the differentiated speed requirements of different formations.
