燃气发电机组启动分析会出现哪些故障？
检查电源或其它电器件可能的原因主要有：
The main possible reasons for checking power supplies or other electrical components are:
蓄电池存电不足，发动机运转无力或转速低；
Insufficient battery storage, weak engine operation or low speed;
起动吸铁开关打滑，碳刷接触不良；
The starting iron suction switch is slipping and the carbon brush has poor contact;
检查各插接件是否松动或被侵蚀；
Check whether each connector is loose or corroded;
导线过长、过细，导致电阻过大，产生电压降；
The wire is too long or too thin, resulting in excessive resistance and voltage drop;
起动机接线不正确。
The starter wiring is incorrect.
检查燃料阀或者节气门是否工作
Check if the fuel valve or throttle valve is working
检查点火系统，火花塞是否点火正常
Check the ignition system and whether the spark plug ignites normally
检查燃气供给
Check gas supply
可能的原因主要有：
The main possible reasons are:
燃气供给不足或管路不通，导致没有足够的燃气；
Insufficient gas supply or blocked pipelines, resulting in insufficient gas supply;
检查燃气是否压力过低，供气不足，空气未排净；
Check if the gas pressure is too low, the gas supply is insufficient, and the air is not completely discharged;
检查燃气是否压力过高，导致进气量过大
Check if the gas pressure is too high, causing excessive intake volume
检查燃气热值，是否符合启动要求，热值过低时，机组启动困难或无法启动
Check the calorific value of the gas to see if it meets the start-up requirements. If the calorific value is too low, it may be difficult or impossible for the unit to start
点火时间是否正确；
6停车手柄未复位。
6停车手柄未复位。
Is the ignition time correct< The parking handle has not been reset.
考虑进气量不足的可能
问题主要在于：
问题主要在于：
The main problem with considering the possibility of insufficient intake volume is:
进气受堵，这主要为空滤器积尘过多或受潮所至；
The intake is blocked, mainly due to excessive dust accumulation or moisture in the air filter;
进排气门间隙过大或过小，发动机会有异常响声；
If the clearance between the intake and exhaust valves is too large or too small, the engine will make abnormal noises;
排气受堵，可能为进气压缩力不足方面。
The exhaust is blocked, which may be due to insufficient compression of the intake air pressure.
