BD DRILL – HJG-W850A WATER WELL DRILLING MACHINE
HJG-W series drilling rig is an versatile internal combustion-driven crawler hydraulic drilling rig that is designed and manufactured elaborately by Changsha Heijingang Industrial Co., Ltd. To ensure the stability of the rig’s performance, the key components are imported. The maximum drilling depth of the rig is up to 500 meters and drilling range is between 105-350mm in diameter. The rig can meet needs under the different geological environments for geothermal projects, the exploration of groundwater, hydro-geological exploration, pile construction and some other projects’ needs. The whole rig is advantageous with a more powerful engine, bigger output torque, higher working efficiency and flexibility, as well as better stability and multi-functions, etc.
Main characteristic of HJG-W850A：
1. Rotary head: Brand: EATON (U.S. Brand)
Rotary power head mounted on the drill, a rotary elecro-hydraulic valve controls two hydraulic motors, enabling rotation speed and the two kinds of gearbox output torque to enable rig adapt to different working conditions.
2. Engine: Power system is diesel drive system. Cummins 93 KW industry-specific engine, hydraulic pump and motor provide a strong impetus for the rigs.
3. Operation platform: The control board is consist of console frame, electro-hydraulic valve, reducing valve, compensated flow control valve, oil pressure gauge, engine instrumentation, cable accelerator, ignition in the control table, that makes operation easier and improve work efficiency.
4. Feeding system: Drilling and lifting are supported by hydro-cylinder-chain plate structure, which is safe, reliable and durable.
5. Hydraulic outrigger: Large stroke hydraulic legs for rig transportation makes loading and unloading without lifting equipment, equipment can be self-loaded, hydraulic legs with the direction of the horizontal instrument to achieve rapid leveling rig.
6. Winch system: Hydraulic motor-powered winch can flexibly hoist less than 1.5 tons of drilling tools or accessories.
7. Generator: The drilling rig is driven by the hydraulic motor. A three-phase synchronous AC generator with a output power of 24KW can be used as an emergency power supply, which is suitable for sleeve welding or any other equipment that requires 380V AC power supply.
8. Wrench hydraulic cylinder: Hydraulic cylinder-powered wrench can disassemble all kinds of joints quickly and lighten labor intensity.
9. Air filter: Two-stage air filter can filter over 90% of dusts in the air inflow, which can effectively reduce the abrasion of engine, endure the lifetime and be used in various severe working conditions.
