在确定多个部位没有故障，判定故障可能发生在燃气装置上。故障排除方法是怎样的？下面燃气发电机组厂家为您讲解。

It is determined that there is no fault in several parts, and the fault may occur in the gas device. What is the troubleshooting method? The manufacturer of gas generator set will explain it to you.

1)燃气动力阀间隙太小，燃气流量不够，混合气过稀。调整动力阀，国Ⅲ系列燃气发电机组的动力阀装在减压器出气口，动力阀有刻度，R(-)方向为减小，L(+)方向为增大。

1) The clearance of the gas power valve is too small, the gas flow is not enough, and the mixture is too thin. Adjust the power valve. The power valve of the national III series gas generator set is installed at the outlet of the pressure reducer. The power valve has a scale. The R (-) direction decreases, and the L (+) direction increases.

2)检查燃气过滤器有无堵塞。

2) Check the fuel gas filter for blockage.

3)检查压力平衡管是否漏气或破损。

3) Check whether the pressure balance pipe leaks or is damaged.

4)增压中冷系统是否有漏气，检查排气管垫、增压器接口、中冷器、混合器、进气管及各连接硅胶管，增压器有无损害。

4) Check the exhaust pipe gasket, turbocharger interface, intercooler, mixer, intake pipe and all connecting silicone hoses of the supercharger for damage.

5)排气管道或三元催化器堵塞，致排气阻力增大。

5) The exhaust pipe or three-way catalyst is blocked, resulting in increased exhaust resistance.

6)检查空气滤清器是否良好，进气管路是否畅通。

6) Check whether the air filter is in good condition and whether the air inlet pipe is unblocked.

7)检查燃气步进电机及减压器出气口到混合器之间的管路。

7) Check the pipeline from the gas stepping motor and pressure reducer outlet to the mixer.

8)混合器皮膜破损，不能形成合理的空燃比，更换皮膜。

8) The skin film of the mixer is damaged and cannot form a reasonable air fuel ratio. Replace the skin film.

9)中低压减压阀二级阀片行程过小。

9) The stroke of the secondary valve plate of the medium and low pressure reducing valve is too small.

10)减压器电磁阀阀芯、阀孔是否破损，进气量不够，更换电磁阀。

10) If the solenoid valve core and valve hole of the pressure reducer are damaged and the air intake is insufficient, replace the solenoid valve.

11)检查低减压器的膜片、弹簧、杆杆有无损害。

11) Check whether the diaphragm, spring and rod of the low pressure reducer are damaged.
