More design advantages
1. BZC350ZY vehicle mounted drilling equipment is a rotary drilling rig.
2. The drilling rig is equipped with SINOTRUK 6*4 drive form 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
BZC350ZY truck mounted drilling 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 vehicle mounted drilling machine with convenience for welding operation and equipment maintenance at night.
5. BZC350ZY is equipped with dual-winch and drill tower pulley block, etc. which functions to increase the drilling pressure and assists the water well drilling rig in drilling 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 legs are hydraulically controlled. The two mechanical legs, transfer case and slurry pump's valves are pneumatically controlled.
7. Power system
BZC350ZY truck mounted drilling 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.
8. Drilling method
A standard BZC350ZY truck mounted drilling rig adopts directional circulation drilling method. Equipped with BW850/2A slurry pump, it utilizes slurry 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 achieve other drilling methods.
Applications
The rotary 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 conservation projects, the drilling of industrial deep well, conventional 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.
