1. What is the Borehole DTH Drilling Rig used for?
It's a portable Down-The-Hole (DTH) drilling rig designed for borehole drilling in construction, water well drilling, foundation and anchoring, geothermal exploration, and other civil engineering applications requiring deep, efficient drilling.
2. What are the key specifications (power, voltage, dimensions, weight)?
Motor power: 3 kW; Voltage: 220 V; Water pump power: 2.2 kW; Product size: 2.45 × 0.83 × 0.9 m; Weight: 27 kg.
3. What drilling depths and diameters can it achieve?
Drilling diameter range: approximately 80–200 mm. Typical rated depth is 100 m (product info); in optimal conditions and with appropriate tooling it can reach up to around 150 m depending on ground conditions and setup.
4. What air pressure and consumption does the rig require?
Operating pressure range: 1.45–2.5 MPa (14.5–25 bar). Air consumption: 16–30 m³/min. Use a compressor that can reliably deliver this pressure and flow.
5. What drill rod sizes are compatible?
Compatible with drill rod diameters of 89 mm and 102 mm; other rod/bit configurations within the machine's spindle and chuck capacity may be usable with proper adapters.
6. What is the spindle speed range?
Spindle speed ranges from 32 to 1,057 r/min, allowing adaptation to different rock types and drilling regimes (impact rotary/DTH operation).
7. Is the rig easy to transport and set up on site?
Yes — the rig is lightweight at 27 kg for portability. However, its length and installed tooling mean transport in a small vehicle or pickup is recommended; setup should be performed by trained personnel and typically takes a short time.
8. What power supply does the rig need?
The rig uses a 220 V electric motor (3 kW). Ensure stable AC power or a suitable generator sized to supply the motor plus any auxiliary equipment.
9. What maintenance does the rig require?
Routine maintenance includes daily inspection of hoses and fittings, lubrication of moving parts, checking and replacing worn bits and valves, monitoring air filters and seals, and scheduled inspection of the motor, pressure vessel, gears and bearings per supplier recommendations.
10. What safety precautions should operators follow?
Operators should wear PPE (hearing protection, eye protection, gloves, safety boots), secure the rig and work area, depressurize air systems before servicing, follow lockout/tagout for electrical work, and ensure only trained personnel operate the rig.
11. What type of compressor do I need to run this rig?
A compressor capable of delivering 1.45–2.5 MPa (14.5–25 bar) and 16–30 m³/min flow is required. For portable applications, a high-pressure, high-capacity compressor (often diesel-powered on site) is typically used.
12. Can the rig be used in hard rock conditions?
Yes — DTH rigs are well-suited for hard rock due to the percussive impact mechanism. Actual performance depends on bit selection, air pressure, compressor capacity, and rod/bit condition.
13. Does the rig include water circulation or flushing capability?
The product lists a 2.2 kW water pump in the product info, indicating support for water circulation/flushing where required. Use of water should follow site requirements and drilling method selected.
14. Are spare parts and technical support available?
Spare parts and technical support availability vary by supplier. Contact the vendor or manufacturer for information on warranty, spare parts kits (bits, valves, seals), and after-sales service.
15. What factors affect achievable drilling depth and productivity?
Key factors include rock/soil type, compressor pressure and flow, bit type and condition, rod string configuration, operator skill, and site logistics. Optimizing these factors yields higher penetration rates and greater depth capability.
