长期闲置的发电机组若缺乏科学保养，极易因腐蚀、润滑失效、电气老化等问题导致“一放就坏”。为确保机组随时可投入应急使用，需落实以下五大核心措施：一、全面清洁与防腐蚀

　　Long term idle generator sets, if not maintained scientifically, are highly susceptible to problems such as corrosion, lubrication failure, and electrical aging, which can lead to "failure as soon as they are released". To ensure that the unit can be put into emergency use at any time, the following five core measures need to be implemented: 1. Comprehensive cleaning and corrosion prevention

　　1、外部防护

　　1. External protection

　　使用压缩空气或软布清除灰尘、油污，重点清洁散热器、风扇叶片，避免堵塞影响散热效率。

　　Use compressed air or soft cloth to remove dust and oil stains, with a focus on cleaning the radiator and fan blades to avoid blockages that affect heat dissipation efficiency.

　　对裸露金属部件喷涂防锈剂，潮湿环境可加装防潮罩。

　　Spray rust inhibitor on exposed metal parts, and install moisture-proof covers in humid environments.

　　2、燃油系统处理

　　2. Fuel system treatment

　　排空燃油箱及管路残留燃油，或添加燃油稳定剂防止胶质沉淀。

　　Drain the remaining fuel from the fuel tank and pipelines, or add fuel stabilizers to prevent gum deposition.

　　柴油机组需定期检查喷油嘴是否结垢，必要时拆洗。

　　Diesel engine units need to be regularly checked for scaling on the fuel injectors, and if necessary, disassembled and cleaned.

　　二、润滑系统深度维护

　　2、 Deep maintenance of lubrication system

　　1、机油管理更换机油及滤芯，推荐使用合成长效机油。

　　1. Oil management: Replace the oil and filter element, and it is recommended to use synthetic long-acting oil.

　　手动盘车2-3圈，使曲轴、活塞等部件表面形成油膜。

　　Manually rotate 2-3 turns to form an oil film on the surface of components such as the crankshaft and piston.

　　2、关键部件润滑对轴承、齿轮等补充高温润滑脂，避免干摩擦导致卡死。三、电气系统防老化

　　2. Lubricate key components by adding high-temperature grease to bearings, gears, etc., to avoid dry friction causing jamming. 3、 Electrical system anti-aging

　　1、电池保养

　　1. Battery maintenance

　　断开负极连线，每月充电一次，铅酸电池需检查电解液密度。

　　Disconnect the negative electrode connection, charge once a month, and check the electrolyte density of the lead-acid battery.

　　电极涂抹凡士林或专用防腐膏。

　　Apply Vaseline or specialized anti-corrosion paste to the electrodes.

　　2、线路与控制器保护

　　2. Line and controller protection

　　使用防潮袋或硅胶干燥剂包裹控制器，检查电缆绝缘层有无龟裂、鼠咬痕迹。四、周期性试运行验证状态

　　Wrap the controller in a moisture-proof bag or silicone desiccant and check for cracks or rodent bite marks on the cable insulation layer. 4、 Periodic trial operation verification status

　　1、空载运行

　　1. No load operation

　　每季度启动一次，运行20-30分钟，观察机油压力、冷却水温是否正常，监听异响。2、负载测试

　　Start once every quarter, run for 20-30 minutes, observe whether the oil pressure and cooling water temperature are normal, and listen for any abnormal noises. 2. Load testing

　　每年模拟实际负载（30%-50%额定功率）运行1小时，验证电压稳定性与瞬态响应。五、环境优化与长期存储

　　Simulate actual load (30% -50% rated power) for 1 hour each year to verify voltage stability and transient response. 5、 Environmental optimization and long-term storage

　　1、存储条件

　　1. Storage conditions

　　温度控制在0-35℃，湿度≤60%，避免阳光直射导致橡胶件老化。

　　Temperature should be controlled between 0-35 ℃, humidity should be ≤ 60%, and direct sunlight should be avoided to prevent rubber parts from aging.

　　若露天存放，需用防紫外线罩包裹机组。

　　If stored outdoors, the unit needs to be wrapped in a UV protective cover.

　　2、生物防护

　　2. Biological protection

　　放置樟脑丸或电子驱鼠器，线缆套金属波纹管。

　　Place camphor balls or electronic rodent repellents, and cover the cables with metal corrugated tubes.

　　通过系统化保养，可显著降低故障率，确保机组在紧急情况下快速投入运行。

　　Through systematic maintenance, the failure rate can be significantly reduced, ensuring that the unit can be quickly put into operation in emergency situations.
