Common faults and solutions for gas generator sets include:

1. 燃气供应中断：检查燃气管道是否有堵塞或泄漏，确保燃气供应正常。解决方法包括修复燃气管道或联系相关部门维修。

1. Gas supply interruption: Check the gas pipeline for blockages or leaks to ensure normal gas supply. The solution includes repairing the gas pipeline or contacting relevant departments for maintenance.

2. 发动机无法启动：检查燃气发动机的电源是否正常，确保电池充电足够。同时检查并更换老化的火花塞或喷油嘴等零部件。

2. Engine cannot start: Check if the power supply of the gas engine is normal and ensure that the battery is fully charged. Simultaneously inspect and replace aging spark plugs or fuel injectors and other components.

3. 高温告警：检查冷却系统是否正常运行，确保冷却液循环畅通和散热器清洁。同时可以增加散热风扇，并在高温时停机降温。

3. High temperature alarm: Check if the cooling system is operating normally, ensuring smooth circulation of coolant and cleanliness of the radiator. At the same time, a cooling fan can be added and the machine can be shut down for cooling during high temperatures.

4. 油压不足：检查机油液面是否足够，是否存在漏油情况。检查并更换损坏的油泵、油路堵塞的零部件。

4. Insufficient oil pressure: Check if the oil level is sufficient and if there is any oil leakage. Check and replace damaged oil pumps and blocked oil circuit components.

5. 发电机输出异常：检查发电机的电压和频率是否符合要求。可以通过校准电压调节器或替换不正常的稳压器来解决。

5. Abnormal generator output: Check if the voltage and frequency of the generator meet the requirements. This can be resolved by calibrating the voltage regulator or replacing an abnormal voltage regulator.

6. 运行不稳定：检查燃气发动机的点火装置、油气比、空气过滤器等关键部件，确保其运行正常。及时进行维护和保养，定期更换磨损的零部件。

6. Unstable operation: Check the ignition device, oil gas ratio, air filter and other key components of the gas engine to ensure their normal operation. Timely maintenance and upkeep, regularly replace worn parts.

对于以上故障，建议定期检查和保养燃气发电机组，确保其正常运行。同时，在故障发生时，如果不具备修理能力，应及时联系的维修服务商进行维修或咨询。

For the above faults, it is recommended to regularly inspect and maintain the gas generator set to ensure its normal operation. At the same time, if a malfunction occurs and you do not have the ability to repair it, you should promptly contact a professional repair service provider for repair or consultation.
