沼气发电机动力下降的原因查找

沼气发电现在应用很大,但是有时会出现沼气发电机动力下降的现象,今天沼气提纯设备公司就给大家总结一下查找沼气发电机动力下降的方法,希望对大家有所帮助!
Biogas power generation is widely used nowadays, but sometimes the power of biogas generators drops. Today, the company of biogas purification equipment summarizes the methods to find the power drop of biogas generators, hoping to be helpful to everyone.
首先要按沼气发电机的检查方法排查一下沼气发电机的工作情况,断缸试验,看是否个别缸不工作或工作不好,每缸作比较;有无气缸漏气现象;气门间隙是否正常。在确定上述部位没有故障,判定故障可能发生在沼气装置上。故障排除方法:
Firstly, according to the inspection method of biogas generator, we should check the working condition of biogas generator, break the cylinder test to see whether individual cylinders do not work or work well, and compare each cylinder; whether there is air leakage in cylinder; whether the valve clearance is normal. There is no fault in the above parts, and the fault may occur in the biogas plant. Troubleshooting methods:
1)沼气动力阀间隙太小,沼气流量不够,混合气过稀。调整动力阀,国Ⅲ系列沼气发电机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 gap of biogas power valve is too small, the flow of biogas is not enough, and the mixture is too thin. By adjusting the power valve, the power valve of Guo III series biogas generator 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)检查沼气过滤器有无堵塞。
2) Check whether the biogas filter is blocked or not.
3)检查压力平衡管是否漏气或破损。
3) Check whether the pressure balancing pipe is leaking or 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) Whether there is air leakage in the pressurized intercooling system, check the exhaust pipe pad, supercharger interface, intercooler, mixer, intake pipe and the silica gel tubes connected with each other, and whether the supercharger is harmless.

5)排气管道或三元催化器堵塞,致排气阻力增大。
5) Blockage of exhaust pipe or ternary catalytic converter results 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 intake pipe is open.
7)检查沼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 between the methane stepper motor and the outlet of the decompressor and 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, so it can not form a reasonable air-fuel ratio and replace the skin film.
9)中低压减压阀二级阀片行程过小。
9) The stroke of secondary valve piece of medium and low pressure relief 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) Whether the valve core and hole of the solenoid valve of the pressure reducer are damaged and the air intake is insufficient, replace the solenoid valve.
