一、沼气发电机组的启动注意事项
1、 Precautions for starting biogas generator units
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 gas circuit switch, turn on the battery key (turn on the solenoid valve switch, confirm that the speed control switch is in the 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, it should first idle and wait until the water and oil temperatures rise, about 45 degrees Celsius. 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. Operate the biogas generator set at the rated speed for a few minutes and close the high-voltage 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 the biogas generator unit: 300 hours, replace the oil once, and replace the air filter oil filter every month. If not in use for a long time, it needs to be started every other period of time, running for half an hour each time. I hope the above introduction can be helpful to users.

二、沼气发电机组出现不能启动的现象怎么办？
2、 What to do if the biogas generator unit fails to start?
1、电瓶电量不足检查电瓶充电量。
1. Check the battery charging capacity when the battery is low.
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 cannot ignite. It is recommended to replace the spark plug as it is a consumable item,
4、燃气管道堵塞
4. Gas pipeline blockage
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。
Over time, there is a large accumulation of water in the flame arrester, and gas cannot be supplied. Or in winter in the north, it freezes inside.
5、沼气里甲烷成份不稳定，或者甲烷浓度不够。
5. The methane content in 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 such as voltage board, speed control board, actuator, speed sensor, etc. Check the corresponding equipment and circuits.
