沼氣發(fā)電機(jī)組動(dòng)力下降是怎么回事
先要按沼氣發(fā)電機(jī)組的檢查方法排查一下沼氣發(fā)電機(jī)組的工作情況，斷缸試驗(yàn)，看是否個(gè)別缸不工作或工作不好，每缸作比較；有無氣缸漏氣現(xiàn)象；氣門間隙是否正常。在確定上述部位沒有故障，判定故障可能發(fā)生在沼氣裝置上。故障排除方法：
First, check the working condition of the biogas generator set according to the inspection method of the biogas generator set, and conduct cylinder breaking test to see whether individual cylinders do not work or work well. Compare each cylinder; Whether there is air leakage in the cylinder; Check whether the valve clearance is normal. After determining that there is no fault at the above parts, it is determined that the fault may occur on the biogas device. Troubleshooting method:
1)沼氣動(dòng)力閥間隙太小，沼氣流量不夠，混合氣過稀。調(diào)整動(dòng)力閥，國Ⅲ系列沼氣發(fā)電機(jī)組的動(dòng)力閥裝在減壓器出氣口，動(dòng)力閥有刻度，R(-)方向?yàn)闇p小，L(+)方向?yàn)樵龃蟆?/div>
1) The clearance of biogas power valve is too small, the biogas flow is insufficient, and the mixture is too thin. Adjust the power valve. The power valve of the national III series biogas generator set is installed at the air outlet of the pressure reducer. The power valve has a scale. The R (-) direction is decreasing and the L (+) direction is increasing.
2)檢查沼氣過濾器有無堵塞。
2) Check whether the biogas filter is blocked.
3)檢查壓力平衡管是否漏氣或破損。
3) Check the pressure balance pipe for air leakage or damage.
4)增壓中冷系統(tǒng)是否有漏氣，檢查排氣管墊、增壓器接口、中冷器、混合器、進(jìn)氣管及各連接硅膠管，增壓器有無損害。
4) Check whether there is air leakage in the supercharging and intercooling system. Check whether the exhaust pipe gasket, supercharger interface, intercooler, mixer, intake pipe and each connecting silicone rubber pipe are damaged.
5)排氣管道或三元催化器堵塞，致排氣阻力增大。
5) The exhaust pipe or three-way catalyst is blocked, resulting in increased exhaust resistance.
6)檢查空氣濾清器是否良好，進(jìn)氣管路是否暢通。
6) Check whether the air filter is in good condition and whether the air inlet pipe is unblocked.
7)檢查沼氣步進(jìn)電機(jī)及減壓器出氣口到混合器之間的管路。
7) Check the pipeline from the gas outlet of biogas stepper motor and pressure reducer to the mixer.
8)混合器皮膜破損，不能形成合理的空燃比，更換皮膜。
8) The mixer membrane is damaged and cannot form a reasonable air-fuel ratio. Replace the membrane.
9)中低壓減壓閥二級閥片行程過小。
9) The stroke of the secondary valve plate of the medium and low pressure reducing valve is too small.
10)減壓器電磁閥閥芯、閥孔是否破損，進(jìn)氣量不夠，更換電磁閥。
10) Check whether the valve core and valve hole of the solenoid valve of the pressure reducer are damaged, and if the air intake is insufficient, replace the solenoid valve.
11)檢查低減壓器的膜片、彈簧、桿桿有無損害。
11) Check the diaphragm, spring and rod of the low pressure reducer for damage.
