沼气发电机组经过一段时间使用后，出现耗气量过高的现象，这时要检查沼气发电机组状况，下面来讲解下吧。

After a period of use, the gas consumption of the biogas generator unit is too high. At this time, check the condition of the biogas generator unit. Let's explain next.

1)检查沼气发电机组水温是否低于80℃，使减压器加热不良，或减压器循环水管被堵，造成减压器有结冰，混合气偏浓。

1) Check whether the water temperature of the biogas generator unit is lower than 80 ℃, which causes poor heating of the pressure reducer, or the circulating water pipe of the pressure reducer is blocked, resulting in icing of the pressure reducer and rich mixed gas.

2)高低压沼气管线、混合器与节气门连接处、进气管、沼气装置及钢瓶是否漏气。

2) Check whether the high and low pressure biogas pipeline, the connection between the mixer and the throttle valve, the intake pipe, the biogas device and the steel cylinder leak.

3)空气滤清器是否干净，进气管路是否畅通。

3) Whether the air filter is clean and whether the air inlet pipeline is unblocked.

4)混合器流量是否调整不当，使混合气过浓。在保证正常启动的情况下，再在混合器膜片上加0.1mm厚铜垫或适当关小功率阀。

4) Whether the mixer flow is adjusted improperly to make the mixture too rich. Under the condition of normal startup, add 0.1mm thick copper pad on the mixer membrane or properly close the power valve.

5)中冷增压沼气发电机组减压器出口压力高，高可达80Kpa，使用检漏液检查沼气出口到进气管之间各部件是否有漏气，用压缩空气检查。

5) The outlet pressure of the pressure reducer of the intercooled supercharged biogas generator set is high, up to 80kPa. Use leakage detection liquid to check whether there is air leakage in all parts between the biogas outlet and the intake pipe, and use compressed air to check.

6)低压减压器输出压力是否过高。

6) Whether the output pressure of the low pressure reducer is too high.

7)检查蓄电池电压是否过低和点火系统是否有故障。

7) Check whether the battery voltage is too low and whether the ignition system is faulty.

8)断缸法检查各缸工作情况。

8) Check the working condition of each cylinder by cylinder breaking method.

9)所有沼气发电机组动力不足，均会引起耗气量增加。

9) Insufficient power of all biogas generating units will cause an increase in gas consumption.

上述检查完成后，若仍没有解决沼气耗气量高的问题，则可能是沼气发电机组技术状况下降，需要检查气门间隙，各缸的气缸压力。关注我们http://www.huannengpower.com，了解更多内容点！

After the above inspection, if the problem of high gas consumption of biogas is still not solved, it may be that the technical condition of biogas generator unit has decreased, and it is necessary to check the valve clearance and the cylinder pressure of each cylinder.
