有时沼气发电机组熄火后，马上启动会出现启动困难，这时要检查一下沼气发电机组的工作情况，看配气系统、点火系统是否有故障，然后检查下面几项：

Sometimes it is difficult to start the biogas generator set immediately after the flameout. At this time, check the working condition of the biogas generator set to see if there is any fault in the gas distribution system and ignition system, and then check the following items:

1)电磁阀过热，阀芯卡滞或磁力下降。

1) The solenoid valve is overheated, the valve element is stuck or the magnetic force drops.

2)电控插头是否有接触不良。

2) Check whether the electric control plug has poor contact.

3)混合器阀芯是否有卡滞现象，使混合气过浓、过稀。

3) Check whether the valve element of the mixer is stuck, so that the mixture is too rich and too thin.

4)减压器输出压力是否过高，超出正常值。

4) Whether the output pressure of the pressure reducer is too high, exceeding the normal value.

5)检查受温度影响的部件。

5) Check components affected by temperature.

5.电磁阀打不开

5. Solenoid valve cannot be opened

减压器电磁阀打不开的原因可能是以下几点：

The reason why the solenoid valve of the pressure reducer cannot be opened may be the following:

1)电源未接通或电磁阀搭铁不好，也可能是电压过低，启动时压降过大，启动时检查电瓶电压，电源变换器输出电压是否有12V。

1) The power supply is not connected or the grounding of the solenoid valve is not good, or the voltage may be too low and the voltage drop is too large during startup. Check the battery voltage and whether the output voltage of the power converter is 12V during startup.

2)磁线圈故障，开启功率不足。

2) Magnetic coil fault, insufficient opening power.

3)阀芯通气孔被堵。

3) The vent hole of the valve element is blocked.

4)ECU无输出控制信号。

4) ECU has no output control signal.

5)阀芯和铁心的配合间隙太小，阀芯不能自由滑动。

5) The fitting clearance between the valve core and the iron core is too small, and the valve core cannot slide freely.

6)阀芯O形圈或橡胶垫损坏。

6) The O-ring or rubber gasket of the valve element is damaged.
