瓦斯发电机组的稳定运行依赖于科学的保养体系，合理规划保养方法与周期，能有效降低故障发生率，延长设备使用寿命。保养需覆盖发动机、瓦斯系统、电气系统等核心部件，结合使用频率与运行环境制定针对性方案。

　　The stable operation of gas generator units relies on a scientific maintenance system. Reasonable planning of maintenance methods and cycles can effectively reduce the occurrence of failures and extend the service life of equipment. Maintenance should cover core components such as the engine, gas system, and electrical system, and develop targeted plans based on usage frequency and operating environment.

　　发动机的保养是设备稳定运行的基础。每次启动前需检查机油液位与质量，若机油乳化或杂质过多，需立即更换，避免润滑不良导致部件磨损，更换周期通常为运行 500 小时或 3 个月（以先到者为准）。冷却系统需每周检查冷却液液位，确保在规定刻度范围内，每运行 1000 小时需更换冷却液，并清洗水箱内部的水垢，防止散热效率下降。空气滤清器需根据环境粉尘浓度定期清洁，粉尘较多的场所每 200 小时清理一次，清洁 3 次后更换新滤芯；正常环境下可每 500 小时更换，避免灰尘进入气缸加剧活塞磨损。火花塞或点火电极需每 300 小时检查一次，清理积碳并调整间隙，磨损严重时及时更换，保证点火效率。

　　The maintenance of the engine is the foundation for the stable operation of the equipment. Before each start-up, the oil level and quality should be checked. If the oil is emulsified or has too many impurities, it should be replaced immediately to avoid component wear caused by poor lubrication. The replacement cycle is usually 500 hours of operation or 3 months (whichever comes first). The cooling system needs to check the coolant level weekly to ensure it is within the specified range. The coolant should be replaced every 1000 hours of operation and the scale inside the water tank should be cleaned to prevent a decrease in heat dissipation efficiency. The air filter needs to be cleaned regularly according to the environmental dust concentration. For places with a lot of dust, it should be cleaned every 200 hours and replaced with a new filter element after cleaning three times; Under normal circumstances, it can be replaced every 500 hours to prevent dust from entering the cylinder and exacerbating piston wear. Spark plugs or ignition electrodes should be checked every 300 hours to clean carbon deposits and adjust clearances. If they are severely worn, they should be replaced in a timely manner to ensure ignition efficiency.

　　瓦斯供应系统的保养关乎运行安全与效率。每日需检查瓦斯管路的密封性，用肥皂水涂抹接口处，观察是否有气泡产生，若发现泄漏需立即停机检修，更换密封件或紧固接头。瓦斯过滤器需每 150 小时清理一次滤网，去除附着的杂质与水分，防止堵塞导致供气不足，每 600 小时更换过滤器滤芯，确保瓦斯纯度。减压稳压阀需每月校准一次，通过压力计检测输出压力，使其稳定在设备规定范围内（通常为 5-10kPa），避免压力波动影响燃烧效率。此外，每运行 200 小时需检查瓦斯喷嘴的通畅性，用专用工具清理堵塞物，保证雾化效果均匀。

　　The maintenance of the gas supply system is related to operational safety and efficiency. Check the sealing of the gas pipeline daily, apply soapy water to the interface, and observe whether bubbles are generated. If a leak is found, immediately stop the machine for maintenance, replace the seal or tighten the joint. Gas filters need to be cleaned every 150 hours to remove attached impurities and moisture, prevent blockages that may cause insufficient gas supply, and replace filter cartridges every 600 hours to ensure gas purity. The pressure reducing and stabilizing valve needs to be calibrated once a month, and the output pressure is detected by a pressure gauge to stabilize it within the specified range of the equipment (usually 5-10kPa), avoiding pressure fluctuations that affect combustion efficiency. In addition, the patency of the gas nozzle should be checked every 200 hours of operation, and special tools should be used to clean blockages to ensure uniform atomization effect.

　　电气系统的保养需注重绝缘与连接可靠性。每周检查电缆接头是否松动、过热，发现烧灼痕迹需立即处理，重新紧固或更换接头，避免接触不良引发电路故障。蓄电池需每 15 天检查一次电量，电压低于 12V 时及时充电，电极桩头若有氧化物需用热水冲洗并涂抹凡士林，防止腐蚀。控制柜内部需每月除尘一次，用干燥压缩空气吹扫线路板与元器件，避免粉尘堆积导致短路，同时检查继电器、接触器的触点状态，出现烧蚀时进行打磨或更换，确保电气元件动作灵敏。

　　The maintenance of electrical systems should pay attention to insulation and connection reliability. Check the cable joints for looseness and overheating every week. If burn marks are found, they should be dealt with immediately, and the joints should be re tightened or replaced to avoid poor contact and circuit failure. The battery should be checked for power every 15 days, and charged promptly when the voltage is below 12V. If there is oxide on the electrode post, it should be rinsed with hot water and coated with Vaseline to prevent corrosion. The interior of the control cabinet needs to be dusted once a month, and the circuit board and components should be blown with dry compressed air to avoid short circuits caused by dust accumulation. At the same time, the contact status of relays and contactors should be checked, and if there is erosion, they should be polished or replaced to ensure the sensitivity of electrical components.

　　辅助系统的定期保养不可忽视。润滑系统的齿轮箱需每 800 小时更换齿轮油，放油时彻底排空旧油并清洗油底壳，加注新油至规定液位，防止齿轮因润滑不足产生异响或磨损。排烟系统需每 300 小时检查排气管路的密封性，清理内部积碳，避免堵塞导致排气背压升高，影响发动机功率。减振装置需每 6 个月检查一次，若橡胶垫老化或弹簧失效，需及时更换，减少设备运行时的振动对部件连接的影响。

　　The regular maintenance of auxiliary systems cannot be ignored. The gearbox of the lubrication system needs to replace the gear oil every 800 hours, thoroughly drain the old oil and clean the oil pan when draining, and add new oil to the specified level to prevent abnormal noise or wear of the gears due to insufficient lubrication. The exhaust system needs to check the sealing of the exhaust pipe every 300 hours, clean the internal carbon deposits, and avoid blockages that may cause an increase in exhaust back pressure and affect engine power. The vibration reduction device needs to be checked every 6 months. If the rubber pad ages or the spring fails, it should be replaced in a timely manner to reduce the impact of vibration during equipment operation on component connections.

　　保养周期需根据运行强度动态调整。连续运行的机组（如每天运行 10 小时以上）需缩短保养间隔，例如机油更换周期可缩短至 400 小时；间歇运行的机组，即使未达到规定运行时间，每 6 个月也需进行一次全面保养，防止部件因长期闲置出现锈蚀或老化。恶劣环境（如高温、高湿度、多粉尘场所）中的机组，需增加滤清器清洁频率，每月额外进行一次管路密封性检查，确保设备适应环境条件。

　　The maintenance cycle needs to be dynamically adjusted according to the operating intensity. Continuous operation of the unit (such as running for more than 10 hours per day) requires a shorter maintenance interval, for example, the oil change cycle can be shortened to 400 hours; Intermittent units, even if they have not reached the specified operating time, require comprehensive maintenance every 6 months to prevent components from rusting or aging due to long-term idle. Units in harsh environments (such as high temperature, high humidity, and dusty areas) need to increase the frequency of filter cleaning and conduct an additional monthly pipeline sealing inspection to ensure that the equipment is suitable for environmental conditions.
