What are the precautions for startup and maintenance of biogas generator set? What should we do if the unit fails to start? Attention shall be paid to the maintenance of biogas generator set, and timely maintenance shall be carried out in case of failure!

一、沼气发电机组的启动注意事项

1、 Precautions for start-up of biogas generator set

1、先检查：循环水，润滑油，气路。

1. First check: circulating water, lubricating oil and air circuit.

2、打开气路开关，扭开电瓶钥匙（打开电磁阀开关，确定转速控制开关处于怠速状态）按下启动开关。

2. Turn on the air circuit switch, turn on the battery key (turn on the solenoid valve switch, and make sure that the speed control switch is in idle state), and press the start switch.

3、沼气发电机组启动后，先怠速运转，等到水温和油温升高，大约45度左右。将转速开关拨至额定转速。

3. After the biogas generator set is started, run it at idle speed until the water temperature and oil temperature rise, about 45 ℃. Turn the speed switch to the rated speed.

4、沼气发电机组按额定转速运转几分钟，合上发电机端高压电输出开关。机组正常发电。

4. Run the biogas generator set at rated speed for a few minutes, and close the high-voltage power output switch at the generator end. The unit generates electricity normally.

需要注意，沼气发电机组维护：300小时，更换一次机油，每月更换空滤机油滤。长期不用要每隔一段时间启动一次，每次运转半小时。希望以上的介绍能给用户带来帮助。

It should be noted that the maintenance of biogas generator set: 300 hours, change the oil once, and change the oil filter of air filter every month. If it is not used for a long time, it should be started every other period of time, and it should run for half an hour each time. I hope the above introduction can help users.

二、沼气发电机组出现不能启动的现象怎么办？

2、 What should we do if the biogas generator cannot be started?

1、电瓶电量不足检查电瓶充电量。

1. The battery is low. Check the battery charge.

2、电瓶线及插头松动。

2. The battery cable and plug are loose.

3、火花塞点不了火。建议更换火花塞，因为火花塞是易耗品，

3. The spark plug will not ignite. It is recommended to replace the spark plug because it is a consumable,

4、燃气管道堵塞

4. Gas pipeline is blocked

时间久了，阻火器那里囤积大量水，燃气通不了。或者在北方的冬天，里面结冰了。

For a long time, there is a large amount of water stored in the flame arrester, and the gas can not be connected. Or in winter in the north, it is frozen inside.

5、沼气里甲烷成份不稳定，或者甲烷浓度不够。

5. The methane component in the biogas is unstable, or the methane concentration is insufficient.

6、电压板、调速板、执行器、速度传感器等回路故障。检查相应的设备及回路。

6. Circuit faults of voltage board, speed governing board, actuator, speed sensor, etc. Check the corresponding equipment and circuits.
