Scope of Application:
The air-lift reverse circulation drilling rig is suitable for drilling construction under complex geological conditions such as ultra-large diameter, ultra-deep boreholes, or hard rock. It is widely used in pile foundation drilling for large onshore buildings, port terminals, embankment protection, bridges, offshore wind power, etc., and is an alternative to other piling equipment.
Performance Features:
1. Fully hydraulic high-power power head with large torque, suitable for drilling in various formations, especially for construction in hard rock and other formations.
2. Fully hydraulic stepless speed regulation, adjusting pump and motor displacement according to working conditions. The constant power controlled hydraulic pump matches the output power of the diesel engine, giving full play to the diesel engine's performance and saving fuel.
3. Powered by a high-power diesel engine, suitable for construction in the field and offshore where no power supply is available.
4. Tiltable gantry and power head, compact structure, convenient for disassembling and assembling drill pipes and drill bits, safe and reliable.
5. Controller with color LCD monitor, monitoring the working status of the diesel engine and system, safe and intuitive.
6. Modular structure, convenient for disassembly and transportation.
7. High-strength operator cabin, protecting the safety of operators.
8. Multiple working modes including automatic drilling, constant pressure drilling, and manual drilling, adapting to construction under various complex geological conditions.
