沼氣發電機組經過一段時間使用后，出現耗氣量過高的現象，這時要檢查沼氣發電機組狀況，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)檢查沼氣發電機組水溫是否低于80℃，使減壓器加熱不良，或減壓器循環水管被堵，造成減壓器有結冰，混合氣偏濃。

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)高低壓沼氣管線、混合器與節氣門連接處、進氣管、沼氣裝置及鋼瓶是否漏氣。

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)空氣濾清器是否干凈，進氣管路是否暢通。

3) Check whether the air filter is clean and whether the air inlet pipe is unblocked.

4)混合器流量是否調整不當，使混合氣過濃。在保證正常啟動的情況下，再在混合器膜片上加0.1mm厚銅墊或適當關小功率閥。

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)中冷增壓沼氣發電機組減壓器出口壓力高，高可達80Kpa，使用檢漏液檢查沼氣出口到進氣管之間各部件是否有漏氣，用壓縮空氣檢查。

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)低壓減壓器輸出壓力是否過高。

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

7)檢查蓄電池電壓是否過低和點火系統是否有故障。

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

8)斷缸法檢查各缸工作情況。

8) Check the working condition of each cylinder with the cylinder cut-off method.

9)所有沼氣發電機組動力不足，均會引起耗氣量增加。

9) Inadequate power of all biogas generator units will lead to increased gas consumption.

上述檢查完成后，若仍沒有解決沼氣耗氣量高的問題，則可能是沼氣發電機組技術狀況下降，需要檢查氣門間隙，各缸的氣缸壓力。更多相關內容就來我們網站http://pyucoin.com進行咨詢吧！

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.
