"BZC-400F Obverse-Reverse Circulation Construction And Water Well Drilling Rig" is listed under
Construction Machinery ToolsCategory
1. According to customers requirements, our truck mounted drilling rig can be equipped with air compressors from different manufacturers, like Americas SULLAIR, Swedens ATLAS COPCO, Chinas KaiShan Group and HongWuHuan Group. Thus, the equipment can achiev e pneumatic down-the-hole hammer drilling.
2. If equipped with air water separator, dual-wall drill pipe and other related devices, the rotary drilling rig is also able to achieve reverse circulation drilling.
3. If equipped with drill tools lik e hy dr aulic down-the-hole hammer, and 850/2A mud pump, the vehicle mounted drilling equipment can realize hydraulic DTH drilling.
More design advantages
1. BZC-350C vehicle mounted drilling equipment is a rotary drilling rig.
2. The drilling rig is equi pped with SINOTRUK special truck chassis, and the transfer case, main drive, gearbox, dual-winch, slurry pump, rotary table, drill tower and steel wire feeding system are all mounted on the chassis.
3. Power system
BZC-350C truck mou nted d rillin g rigs are equipped with automotive engines, and also additionally equipped with transfer case and hydraulic system. Hence, the truck and the drilling mechanism can work simultaneously.
4. Three-phase AC generating set provides the veh icle mou nted dri lling ma chine with convenience for welding operation and equipment maintenance at night.
5. BZC-350C is equipped with dual-winch and drill tower pulley block, etc. which functions to increase the drilling pressure and assists the w ater well drilling r ig in dril ling into mud rock, and bed rock, etc. This design is very effective in improving drilling efficiency.
6. Driving system
This truck mounted drilling rig is principally mechanical driven. The drill tower and the four levelling l egs are hydr aulically co ntrolled. The two mechanical legs, transfer case and slurry pumps valves are pneumatically controlled.
7. Power system
BZC-350C truck mounted drilling rigs are equipped with automotive engines, and also additi onally equippe d with transfe r case and hyd raulic system. Hence, the truck and the drilling mechanism can work simultaneously.
8. Drilling method
A standard BZC-350C truck mounted drilling rig adopts directional circulation drilling method. Equip ped with BW850/2 A slurry pump, i t utilizes slurr y as the drilling fluid, and finally achieves direct circulation drilling with the help of the high pressure plunger pump.
If equipped with proper drilling tools, the drilling machine can also achiev e other drilling m ethods.
The rotar y table of this truck mounted drilling rig comes with large torque and as a result the drill equipment makes a hole quickly. Currently, our drilling rig has found applications in water conservati on projects, the dri lling of industrial deep well, conventio nal water well and geothermal well, etc., and national defense fields, to name a few. It is applicable for drilling into clay, sand, bed rock, basalt strata, and more.
