FAQ Section
1. Question: What are the characteristics of the cooling system of Weichai marine generators?
Answer: Weichai marine generators use seawater heat exchange cooling system. The seawater pump can be supplied randomly, and the seawater cooling part should be equipped with a coarse filter, a water filter, and a check valve (prepared by the user). In high-power models (such as 6WH20), advanced cooling system design is used to ensure stable operation in high-temperature environments.
2. Question: What is the difference between the usual power and continuous power of a marine generator? How to choose?
Answer: According to Weichai’s official statement:
Common power: 24h average load rate does not exceed 70%, and can be overloaded by 10% for 1 hour every 12 hours
Continuous power: allowed to operate at constant 100% load, and can operate at 10% overload for 1 hour every 12 hours
Selection recommendations: Ocean fishing boats operating for more than 3,000 hours per year should be matched according to continuous power; inland river transport ships and coastal fishing boats can be matched according to common power
3. Question: What are the starting methods for Weichai marine generator sets?
Answer: Weichai marine generator sets support both electric start and gas start. The electric start system uses 24V DC to start, and some low-power models (such as 100kW) use a 12V system.
4. Question: What are the precautions for daily management of emergency generators?
Answer: According to ship management experience:
Daily inspection: oil and water level, cooling water heating (cold areas), crankcase oil heating
Weekly inspection: battery capacity, two starting methods starting test
Every six months: Conduct a load test to record diesel engine speed, oil pressure, frequency, voltage and other parameters
Every six months: Tighten the emergency switchboard internal terminal screws
