Heavy-Duty Diesel Generator for Rock Drill Jumbos This 30kW diesel generator is engineered to deliver stable power in harsh mining environments. Its robust design ensures reliable performance in high-vibration, dusty conditions, reducing downtime for critical operations like hydraulic pump drives and ventilation systems .
Technical Specifications & Design
Power Generation:
3-phase output at 380V/400V/415V (50Hz), compatible with rock drill jumbo electrical systems requiring 380V/1000V input .
90% efficiency at rated load, minimizing fuel consumption and operating costs .
Engine & Cooling:
4-cylinder diesel engine (2.8L displacement) provides 45kW peak power, ensuring consistent output even under sudden load changes.
IC411 self-cooling system with radiator maintains optimal temperature across -20°C to +50°C ambient conditions .
Environmental Protection:
IP54-rated cast steel housing (EN-GJL-250) prevents dust ingress and water spray, critical for underground mining .
950kg total weight and NEMA 254T frame ensure stability during transportation and installation .
Performance Advantages
Rapid Start-Up:
Cold-start capability at -20°C with glow plug preheating, ideal for freezing underground environments.
Low Maintenance:
Double-sealed bearings and self-lubricating components reduce service intervals to 500 hours.
Safety Compliance:
Overload protection (110% for 1 hour) and short-circuit protection meet IEC 60034-1 standards.
Applications
Rock Drill Jumbos: Powers hydraulic pumps, conveyor systems, and lighting in tunnel excavation.
Mining Equipment: Supports loaders, crushers, and auxiliary tools in abrasive conditions.
Emergency Backup: Provides temporary power during grid outages in remote mining sites.
