marine diesel generator is crucial for power supply on ships, but their harsh operating environment requires strict operating procedures. Follow these guidelines to ensure their reliability.
1. Pre-Start Checks of marine diesel generator
Fuel Quality: Use marine-grade diesel to prevent microbial contamination in humid conditions.
Coolant & Oil: Check levels and condition—saltwater exposure accelerates corrosion.
Battery & Cables: Inspect for corrosion, common in salty air.
2. Startup & Load Management of marine diesel generator
Warm up the engine at low load for 3–5 minutes to stabilize oil pressure.
Gradually add electrical loads to avoid sudden stress on the marine diesel generator.
Avoid prolonged operation below 30% load; it causes carbon buildup.
3. During Operation of marine diesel generator
Monitor exhaust (white smoke may indicate coolant leakage).
Ensure proper ventilation to prevent overheating in confined engine rooms.
Regularly check vibration mounts—loose fittings worsen with wave impacts.
4. Shutdown & Maintenance
Reduce load before turning off to let the engine cool evenly.
Flush the cooling system with freshwater if seawater-cooled.
Store spare parts in moisture-proof containers.
By adhering to these practices, the marine diesel generator can deliver stable performance even in challenging marine conditions.
