MWLH-800 Fully hydraulic core drilling rig
MWLH-800 Full Hydraulic Core Drilling Rig is a high-efficiency drilling equipment designed for deep-hole geological exploration, with the following core parameters and technical features:
Performance Parameters
Drilling capacity: Supporting three standard core pipe diameters of BQ, NQ and HQ, the maximum drilling depth reaches 800-1200 metres, adapting to complex stratigraphic conditions.
Power system: Hydraulically driven power head with 0-1400rpm rotary speed and 1800N-m torque, combined with 150kN propulsion force and 300kN lifting force to ensure drilling efficiency and stability.
Modular design: Split structure, power head stroke 3500mm, machine weight 6000kg, dimensions 5900×2500×2100mm, easy to transport and rapid deployment.
Technical Advantages
1. All-hydraulic transmission: integrated high-precision hydraulic components (such as axial piston pumps, servo valves), which can operate stably under high-pressure (32MPa) and high-temperature (80℃) environments, and the tolerance of cylindricity of the outer diameter of the hydraulic valve core is only 0.0005mm, which ensures the system’s reliability.
2. Precise coring: adopting diamond/carbide drill bit, the core taking rate is over 95%, supporting full-hole follow pipe drilling, applicable to complex environments such as broken strata and collapse-prone strata.
3. Green and efficient: Supporting BW160 mud pump, adopting environmental protection technology, reducing the destruction of vegetation, no need to build roads, reducing construction costs by 20%-30%.
