关于交流柴油发电机的保养，虽然柴油发电机保养是很少需要进行，但是我们也是建议要作定期的检查及清洁。对线圈的绝缘性能在次使用之前作测试。

Regarding the maintenance of AC diesel generators, although diesel generator maintenance is rarely required, we also recommend regular inspections and cleaning. Test the insulation performance of the coil before the first use.

如发电机停机备用，则视乎存放地点的温度，3-6个月检测绝缘度一次，在高温度地区，当机器不使用时安装发热器来驱温，将有助于保持线圈的乾燥。

If the generator is shut down for backup, the insulation degree should be checked every 3-6 months depending on the temperature of the storage location. In high temperature areas, installing a heater to drive the temperature when the machine is not in use will help keep the coils dry.

如交流柴油发电机装有空气过滤器则要视乎机址环境来进行定期的视察，如需进行清洁，把过滤器的材料拆下来，把材料浸或冲洗：可加入适当的除污剂直到材料乾净为止。在装回去之前要把材料完全弄乾。

If the AC diesel generator is equipped with an air filter, regular inspections should be carried out depending on the site environment. If cleaning is required, remove the filter material and soak or rinse it: appropriate cleaning agents can be added until the material is clean. Before installing it back, completely dry the materials.

再者，交流柴油发电机的内外都应定期清洁，而清洁的频率则要视乎机器所在地的环境。当要清洁时可按下列步骤进行。将所有电源断开，把外表所有的尘、污物、油积、水及任何液体擦掉，通风网也要清洁干净，因为这些东西进入线圈，这样就会使线圈过热或破坏绝缘。尘和污物较好用吸尘器吸掉，不要用吹气或高压喷水来清洁。

Furthermore, both the inside and outside of the AC diesel generator should be regularly cleaned, and the frequency of cleaning should depend on the environment where the machine is located. When cleaning, follow the following steps. Disconnect all power sources, wipe off all dust, dirt, oil, water, and any liquids on the surface, and clean the ventilation net thoroughly, as these things can enter the coil, causing it to overheat or damage the insulation. It is better to use a vacuum cleaner to remove dust and dirt, and do not use blowing air or high-pressure water spray to clean.

使用环境的气温对柴油发电机组的磨损也是有影响的。气温高时发动机易过热，润滑油粘度低，零件的磨损便增加。气温低时润滑油粘度变大，柴油发电机组起动困难，工作时冷却水不能保持正常温度，增加零件的磨损和腐蚀。柴油机在低温起动时，磨损更为严重。柴油发电机组的工作温度是影响磨损的重要因素之一。在使用过程中，由于冷却系统结构的限制，工作负荷及转速的变化，环境温度的改变等因素，使柴油发电机组工作温度的变化范围很大。实践表明，冷却水温度控制在75～85℃，润滑油温度在75～95℃时一为有利

The temperature of the operating environment also has an impact on the wear and tear of diesel generator sets. When the temperature is high, the engine is prone to overheating, the viscosity of lubricating oil is low, and the wear of parts increases. When the temperature is low, the viscosity of lubricating oil increases, making it difficult to start the diesel generator set. During operation, the cooling water cannot maintain normal temperature, which increases the wear and corrosion of parts. Diesel engines experience more severe wear during low-temperature starting. The working temperature of diesel generator sets is one of the important factors affecting wear. During use, due to the limitations of the cooling system structure, changes in working load and speed, changes in ambient temperature, and other factors, the operating temperature of diesel generator sets varies greatly. Practice has shown that controlling the temperature of cooling water at 75-85 ℃ and lubricating oil at 75-95 ℃ is advantageous
