FAQ Section
1. Q: What is the fuel consumption rate of 600-1000kW marine generator?
A: According to Cummins data, the fuel consumption rate of large units (above 1000kW) can be optimized to 180-200g/kWh. Taking an 800kW unit as an example, the fuel consumption per hour at full load is about 150-170 liters (converted based on fuel density 0.85kg/L). The specific fuel consumption depends on the load rate. It is recommended to operate in the economic load range (70-85% load).
2. Q: Which classification society certifications can Cummins marine generators obtain?
A: Certifications from IACS member classification societies can be provided, including: CCS (China), ABS (USA), BV (France), DNV (Norway), LR (UK), NK (Japan), KR (South Korea), RINA (Italy), etc. The standard configuration is CCS certified, and other classification societies can order it on demand. Emissions meet IMO Tier II standards.
3. Q: What cooling system is used for 600-1000kW marine generators?
A: The standard seawater heat exchanger cooling system (Heat Exchanger Cooled) includes seawater pump, heat exchanger and expansion tank. A high-temperature environment (40°C) cooling system is standard, and a 50°C enhanced high-temperature environment cooling system is optional. Zinc anodes need to be inspected regularly on the seawater side to prevent electrochemical corrosion.
4. Q: What are the functions of the unit’s control system? How to deal with fault alarms?
A: Equipped with Cummins intelligent control panel, which can display voltage, current, frequency, oil pressure, water temperature, operating hours and other parameters in real time. In the event of a malfunction, the amber status light will flash a digital fault code. Common fault codes include: 2 flashes (low oil pressure), 4 flashes (start timeout), 5 flashes (CO concentration too high), 7 flashes (loss of seawater flow). Press the STOP button to redisplay the fault code.
