To determine the minimum fuel tank size for your required runtime:
公式: 罐体尺寸 (L) = 燃油消耗量 75% 加载 (升/小时) x 所需的运行时间 (小时) X 1.1 (10% 安全裕度)
- 8-小时运行时间: 908L minimum
- 24-小时运行时间: 2722L minimum
- 48-小时运行时间: 5445L minimum
为了延长运行时间, 考虑使用带有自动燃油传输功能的外部日用油箱, 或双燃料 (柴油机 + 天然气) 配置. 看看我们的 发电机燃油消耗指南 进行详细计算.

投资回报率分析
The return on investment for a 625kVA generator depends on your industry’s cost of downtime. Below are three scenarios:
| 公制 | 医院 | 数据中心 | 工厂 |
|---|---|---|---|
| Downtime Cost/hour | $15,000 | $50,000 | $10,000 |
| Generator Investment | $193,750 | $275,000 | $162,500 |
| Payback (1 outage event, 4小时) | 3.2 事件 | 1.38 事件 | 4.1 事件 |
| 每年节省 (2 outages/year) | $120,000 | $400,000 | $80,000 |
Key Insight: Even a single 4-hour outage event justifies the investment for most commercial and industrial applications. 对于数据中心, the generator pays for itself after less than one outage event.
常问问题
1. How do I size a 625kVA generator for my facility?
Add up the running kW of all loads, then apply a 1.25x diversity factor for non-simultaneous loads. Add motor starting kVA (typically 6x FLA for DOL starting). Ensure the generator’s standby rating exceeds your total demand. 看看我们的 发电机选型指南 for step-by-step calculations.
2. What is the difference between prime and standby power?
Prime power means the generator can run continuously at variable loads with no limit on hours per year. Standby power is the maximum output available for emergency use only (通常 <200 小时/年). The 625kVA rating is prime power; standby rating is approximately 687kVA.
3. Can I run a 625kVA generator in parallel with another unit?
是的. With a synchronizing panel and appropriate control modules (例如, Deep Sea DSE8610 or ComAp InteliGen), 最多 10 generators can be paralleled for increased capacity or N+1 redundancy. Paralleling requires matched voltage, 频率, and phase angle.
4. What maintenance schedule does a 625kVA generator need?
Oil and filter change every 250 营业时间或 6 月 (以先到者为准). Air filter replacement every 500 小时或每年. Coolant replacement every 2 年. Load bank test monthly for standby units. Full service inspection annually.
5. How long can a 625kVA generator run continuously?
With the base fuel tank (312L), 大约 4 小时于 75% 加载. With an external day tank, 24-48 hours is standard. For continuous prime power applications, weekly shutdown for oil checks is recommended.
6. Does a 625kVA generator meet emissions regulations?
Models with Cummins QSK-Series engines meet EPA Tier 4 最终的 (美国) and EU Stage V standards. For regions with less stringent requirements, 等级 2 or Tier 3 options are available at lower cost. Always verify local emissions requirements before purchasing.
7. What is the expected lifespan of a 625kVA generator?
A well-maintained diesel generator typically lasts 20,000-30,000 running hours before major overhaul. 对于待机应用 (200 小时/年), that translates to 50-100 年. For prime power applications (6,000 小时/年), expect 3-5 大修前几年.
8. What is the noise level of a 625kVA silent generator?
Open type: 95-105 分贝(一个) 和1m. 静音型 (隔音天篷): 65-75 分贝(一个) 和7m, suitable for residential areas and hospital zones. Super-silent options can achieve <60 分贝(一个) at 7m with residential-grade exhaust silencers.
9. Can I convert a 625kVA diesel generator to run on natural gas?
Dual-fuel conversion kits are available (通常 70% 柴油机 + 30% gas or full gas conversion). Gas derating is approximately 15-20% reduction in output. Biogas options are also available for agricultural applications with methane capture.
10. 华泉电源提供哪些保修?
标准保修: 12 交货后几个月或 1000 运行时间 (以先到者为准). Extended warranty options up to 5 years are available. 保修范围涵盖发动机, 交流发电机, and control system manufacturing defects.
