Here is the professional English translation of the management summary for the dual-fuel generators (Wärtsilä 9L34DF & 6L34DF):
I. Core Management Points for Pilot Fuel System**
1. **System Criticality**
- Pilot fuel failure → Automatic switch to backup mode (diesel-only operation) → **Automatic shutdown after 30 minutes**.
- Gas mode relies on pilot fuel ignition (methane requires 900Bar diesel injection due to high ignition point).
2. **Common Failure Causes**
- Phase sensor failure
- Pilot fuel pump pressure sensor malfunction
- Low/high pilot fuel pressure
- Combustion monitoring system failure
II. Key Daily Management Measures**
(1) Pilot Fuel Pressure & Cleanliness Control**
- **Pressure Maintenance**:
- Maintain stable **900Bar**; investigate fluctuations immediately (regulator valve sticking, filter blockage).
- **Fuel Cleanliness Management**:
- **Filter Maintenance Cycle** (per 500hrs or manual):
**Filter Type** **Maintenance Action** | **Regeneration Method** |
| Supply pump filter | Periodic cleaning | Soak in fuel detergent + air-dry |
| Inlet coarse filter | Periodic cleaning | Same as left |
| **Paper fine filter** | **Replace every 500hrs** | Test filtration efficiency after soak|
| **Metal filter** | **Clean/replace** | Steam-clean + check permeability |
- **Regulator Valve Maintenance**: Disassemble, clean, lubricate valve core; flush with pure diesel.
(2) High-Pressure Fuel System Maintenance**
- **Fuel Pump Rack**:
- Manually operate before startup; **regularly lubricate** to prevent sticking.
- **Injectors (Main nozzles)**:
- Withdraw and inspect per manual; verify atomization quality and sealing.
(3) Scheduled Mechanical Maintenance**
- Valve clearance adjustment (prevent gas leaks/backfire)
- Crankshaft deflection measurement (monitor deformation)
- Piston ring/liner inspection (increased carbon buildup in gas mode)
III. Operational Notes**
1. **Mode Switching & Parallel Operation**
- **Parallel operation**: Switch to **isochronous mode** (avoid reverse power tripping).
- **Gas/diesel transition**: Confirm stable pilot fuel pressure before mode change.
2. **Emergency Response**
- Backup mode activation: Troubleshoot pilot fuel issues **within 30min** to prevent shutdown.
- Maintain sufficient emergency diesel reserves.
IV. Optimization Recommendations**
1. **Spare Parts Management**:
- Stock **paper fine filters** + **regulator valve seals** (high-pressure components wear fast).
- Regenerated filters for emergency use only (≤2 reuses).
2. **Monitoring Enhancement**:
- Install real-time pilot fuel pressure alarm (earlier than UNIC system alerts).
3. **Personnel Training**:
- Drill UNIC control operations (especially sensor failure simulations).
**Pro Tip**: In gas mode, pilot fuel accounts for only 1% of total consumption but 90% of system safety. Timely filter maintenance is the primary defense against unplanned shutdowns!
以下是根据您提供的双燃料发电机(WARTSILA 9L34DF & 6L34DF)管理要点及日常管理的系统化总结,结合技术原理和实操经验整理:
一、引燃油系统核心管理要点**
1. **系统重要性**
- 引燃油故障 → 自动切换至备用模式(仅柴油模式)→ **30分钟后自动停机**。
- 燃气模式依赖引燃油点燃(甲烷燃点高,需900Bar高压柴油引燃)。
2. **故障常见原因**
- 相位传感器故障
- 引燃油泵压力传感器异常
- 引燃油压力过低/过高
- 燃烧监测系统故障
*二、日常管理关键措施**
(1) 引燃油压力与清洁度控制**
- **压力维持**:
- 确保稳定在 **900Bar**,波动需立即排查(调压阀卡阻、滤器堵塞)。
- **燃油清洁度管理**:
- **滤器维护周期**(按500小时或说明书):
| **滤器类型** | **维护动作** | **再生处理建议**
| 供给泵滤器 | 定期清洗 | 燃油清洁剂浸泡 + 压缩空气吹干 |
| 进机粗滤器 | 定期清洗 | 同左 |
| **纸质细滤器** | **每500小时更换** | 浸泡试验后检测过滤效能 |
| **金属滤器** | **清洗/更换** | 蒸汽吹干 + 检测通透性 |
- **调压阀保养**:拆解阀芯清洁活络,用纯净柴油冲洗。
(2) 高压燃油系统维护**
- **高压油泵齿条**:
- 启动前手动活络,**定期加注滑油**防卡滞。
- **喷油器(主油头)**:
- 按说明书周期抽出检查,校验雾化质量及密封性。
(3) 机械定期维护**
- 气阀间隙调整(预防燃气泄漏/爆燃)
- 曲轴拐档差测量(监控曲轴变形)
- 活塞环/缸套检查(燃气模式积碳更严重)
三、运行操作注意事项**
1. **模式切换与并车**
- **并车操作**:切换至 **恒频模式**(避免逆功率导致跳闸)。
- **燃气/柴油切换**:确认引燃油压力稳定后再切换模式。
2. **故障应急响应**
- 备用模式触发后:**30分钟内**排查引燃油故障,否则停机。
- 备用柴油储备量需满足紧急续航需求。
四、优化建议**
1. **备件管理**:
- 储备 **纸质细滤器** + **调压阀密封件**(高压部件易损)。
- 再生滤器仅作应急备用,避免重复使用超2次。
2. **监测升级**:
- 加装引燃油压力实时报警装置(早于UNIC系统预警)。
3. **人员培训**:
- 强化UNIC控制系统操作演练(特别是传感器故障模拟)。
| **引燃油压力** | 维持900Bar,监控波动 | 实时监测 **经验提示**:燃气模式下,引燃油消耗量仅为总能耗的1%,但其可靠性占系统安全的90%。滤器维护的及时性是避免非计划停机的第一防线!
