合金尾气发电机组启动后自动停机且无报警，可能由多种原因导致。以下是排查故障的步骤及重点检查点：

　　The automatic shutdown of the alloy tail gas generator set without any alarm after startup may be caused by various reasons. The following are the steps and key checkpoints for troubleshooting:

　　一、检查气路系统

　　1、 Check the pneumatic system

　　合金尾气供应检查

　　Alloy exhaust gas supply inspection

　　检查气瓶阀门是否关闭严密，压力是否正常（可通过压力表测量）。

　　Check whether the valve of the gas cylinder is tightly closed and whether the pressure is normal (which can be measured by a pressure gauge).

　　检查进气管路是否堵塞或空气滤清器是否清洁。

　　Check if the intake pipe is blocked or if the air filter is clean.

　　检查燃料管道是否有泄漏，尤其是连接件和接头处。

　　Check for leaks in the fuel pipeline, especially at the connections and joints.

　　混合气质量

　　Mixed gas quality

　　通过参数超标保护系统判断混合气是否过稀或过浓，必要时调整减压器或喷阀。

　　Determine whether the mixture is too lean or too rich through the parameter over limit protection system, and adjust the pressure regulator or spray valve if necessary.

　　二、检查点火系统

　　2、 Check the ignition system

　　点火模块与线路

　　Ignition module and wiring

　　检查点火模块电源指示灯及线束插口是否正常，动力缸线路有无接地故障。

　　Check whether the ignition module power indicator light and harness socket are normal, and whether there is a grounding fault in the power cylinder circuit.

　　检查火花塞电极间隙及积碳情况，必要时更换火花塞。

　　Check the electrode gap and carbon deposition of the spark plug, and replace the spark plug if necessary.

　　高压系统检测

　　High voltage system testing

　　启动时听高压电磁阀是否有“喀哒”声，检查高压线是否漏电。

　　When starting, listen for a "click" sound from the high-voltage solenoid valve and check for any electrical leakage in the high-voltage line.

　　三、检查控制系统

　　3、 Check the control system

　　传感器与执行器

　　Sensors and actuators

　　检查曲轴凸轮轴转角传感器、ECU等是否正常工作。

　　Check if the crankshaft camshaft angle sensor, ECU, etc. are working properly.

　　检查12V/24V电源系统是否稳定，继电器是否正常。

　　Check if the 12V/24V power system is stable and if the relays are functioning properly.

　　保护系统触发

　　Protection system triggered

　　查看故障显示表，确认是否因参数超标（如压力异常）触发紧急停机。

　　Check the fault display table to confirm if the emergency stop was triggered due to parameter exceedance (such as abnormal pressure).

　　四、其他检查项

　　4、 Other inspection items

　　冷却系统

　　cooling system

　　检查冷却水管路是否漏水，风扇是否正常运转，节温器是否卡住。

　　Check whether the cooling water pipeline is leaking, whether the fan is running normally, and whether the thermostat is stuck.

　　机械部件

　　mechanical parts

　　听机组运行声音，检查是否有异常敲击声或振动，排除机械故障。

　　Listen to the sound of the unit running, check for any abnormal knocking or vibration, and eliminate mechanical faults.

　　五、处理建议

　　5、 Suggestions for handling

　　若上述检查未发现问题，建议逐步排查燃油系统、热工保护系统等。

　　If no problems are found during the above inspection, it is recommended to gradually investigate the fuel system, thermal protection system, etc.

　　若故障复杂，需联系专业人员使用专业设备检测。

　　If the fault is complex, it is necessary to contact professionals to use professional equipment for testing.
