6. FAQ (Frequently Asked Questions)

Q1: What is the difference between prime power and standby power of the 320kW WP13D405E200 generator set?

A1: The 320kW (400kVA) prime power is the rated continuous operating power of the generator set, supporting 24-hour long-term stable operation and allowing short-term slight overload operation, which is suitable for daily continuous power supply of factories, mines and construction sites. The 350kW (437.5kVA) standby power is emergency peak power, only used for short-time power supply in sudden power failure or peak load emergencies. It cannot run continuously for a long time under standby load, otherwise it will cause accelerated engine wear, increased fuel consumption and shortened service life. Users need to match the load according to actual long-term power consumption.

Q2: What are the actual advantages of brushless self-excited alternator with H-class insulation and IP23 protection?

A2: Compared with traditional brushed generators, the brushless self-excited structure removes carbon brushes and slip rings, reducing daily maintenance workload and failure probability. H-class high-temperature insulation can resist long-term high-temperature aging during high-load operation and avoid insulation breakdown. IP23 professional protection grade effectively isolates dust, moisture and rain splash, ensuring stable operation in outdoor and harsh industrial environments. The three configurations cooperate to greatly improve the durability and operational stability of the 400kVA diesel generator, which is the core reason for its wide application in industrial high-load scenarios.

Q3: Is the 85.6L/H fuel consumption of this 320kW Weichai generator economical in actual use?

A3: The 85.6L/H data is the standard full-load fuel consumption under rated working conditions, which is a professional and reasonable level for 320kW high-power industrial generators. Matched with Weichai’s optimized combustion technology, the unit has low carbon deposition rate and high combustion efficiency. In actual use, keeping the load rate between 60% and 80% can achieve the best fuel-saving effect with lower average fuel consumption. Regular replacement of filter elements and lubricating oil can further maintain engine working efficiency and reduce comprehensive operating costs, presenting good overall economic performance for long-term industrial operation.
