DQ30BQ-VSP Core Advantage:
1.Rated Load and Torque
The DQ30BQ-VSP features a rated load of 1,800 kN (≈200 tons) and delivers a static maximum braking torque of 27.5 kN·m, a rated continuous output torque of 27.5 kN·m, and a maximum instantaneous breaking torque of 41 kN·m. This parameter combination ensures robust performance in hard rock drilling, stuck pipe recovery, and high-resistance well sections.
Technical Advantage: Optimized gearbox transmission ratios and hydraulic braking systems enable linear torque response, minimizing drill string vibrations caused by sudden torque changes and extending tool life.
2.Main Motor and Energy Efficiency
Equipped with a 290 kW high-power main motor utilizing vector frequency conversion control technology, the system supports infinitely adjustable speeds from 0-200 r/min. The motor delivers constant torque at low speeds for precise directional drilling, while high-speed operation facilitates rapid drilling or reaming. Compatible with 600 VAC/50Hz power input, it aligns with global grid standards, reducing electrical retrofitting costs for overseas projects.
3. Structural Design and Dimension
With overall dimensions of 4,740 mm × 970 mm × 1,267.5 mm, the system adopts a modular design integrating the main motor and hydraulic systems, achieving a 15%-20% weight reduction compared to similar products. The short-axis design (532.5 mm distance between the main shaft center and guide rail center) minimizes derrick footprint, ideal for space-constrained offshore platforms.
4.Back Up Tong and Drill Pipe Compatibility
The back-up tong accommodates drill pipe diameters of 85-187 mm, covering API-standard drill pipes and heavyweight drill pipes for rapid tool changes. The 0-360° rotating link adaptor, combined with hydraulic-assisted alignment, reduces stand connection time to under 30 seconds.
5.Environmental Adaptability
Engineered with low-temperature materials (-45°C-rated hydraulic oil, cryogenic seals) and a high-temperature cooling system (forced air + circulating water cooling), the system operates reliably in extreme temperatures from -45°C to 55°C. For example, in Arctic permafrost drilling, preheating systems ensure hydraulic fluid mobility, while desert operations maintain motor temperature rise below 65°C.
6.High-Pressure Mud Circulation
The mud channel supports dual pressure modes (35 MPa standard / 52 MPa boost), enabling high-pressure jet drilling for ultra-deep wells. The dual-redundant hydraulic Internal Blowout Preventer (IBOP) rated at 105 MPa automatically shuts down within 0.5 seconds during kicks, ensuring well control safety.
7.Intelligence and Reliability
Closed-Loop Control and Data Integration
The PLC-based electrical control system monitors torque, RPM, hook load, and other parameters in real time, interfacing with the driller's cabin for automated drilling, overload protection, and fault alerts. For instance, abnormal torque fluctuations trigger automatic slowdowns or shutdowns to prevent drill string failures.
8.Ease of Maintenance
Featuring quick-disconnect hydraulic lines and a split gearbox design, critical components (e.g., main shaft bearings) have an extended maintenance interval of 5,000 hours, reducing lifecycle costs. Wear-monitoring interfaces on guide rails and hoisting sprockets enable vibration-based fatigue prediction.
