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，如下：

After using the biogas generator set for a period of time, the gas consumption is too high. At this time, check the condition of the biogas generator set, as follows:

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 set is lower than 80 ℃, which causes poor heating of the pressure reducer, or the circulating water pipe of the pressure reducer is blocked, which causes the pressure reducer to freeze and the mixture gas is too thick.

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) 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) Check whether the air filter is clean and whether the air inlet pipe 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 flow of the mixer is adjusted improperly to make the mixture too rich. Under the condition of ensuring normal startup, add 0.1mm thick copper pad on the mixer diaphragm or turn down the power valve properly.

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 booster biogas generator set is high, up to 80Kpa. Use the leak detection solution to check whether there is gas leakage in the components 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 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 with the cylinder cut-off method.

9)所有沼气发电机组动力不足，均会引起耗气量增加。

9) Inadequate power of all biogas generator units will lead to increased 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。更多相关内容就来我们网站//www.gz-yanye.com进行咨询吧！

After the above inspections are completed, if the problem of high biogas consumption is still not solved, it may be that the technical condition of the biogas generator set has declined, and the valve clearance and cylinder pressure of each cylinder need to be checked.
