沼气发电机组是电故障和停电后应急备用电源的提供者。大部分时间，沼气发电机组处于备用状态。万一停电，沼气发电机组无法紧急启动，那么后备单位就失去了意义。实践证明，加强日常维护是一种经济有效的方法。

Biogas generator unit is the provider of emergency standby power supply after power failure and power failure. Most of the time, the biogas generator unit is in standby state. In case of power failure, the biogas generator unit cannot be started urgently, then the backup unit will lose its significance. Practice has proved that strengthening daily maintenance is an economic and effective method.

1.沼气发电机组启动电池故障，电池长时间未维修。电解液蒸发后，不能立即补充。没有启动电池充电器，长期自然放电后电池容量下降。使用的充电器需要手动定期充电和更换。由于忽视更换操作，电池电量达不到要求。要解决这个问题，除了配置高质量的充电器，还需要必要的检查和维护。

1. The start-up battery of the biogas generator unit failed and the battery was not repaired for a long time. The electrolyte cannot be replenished immediately after evaporation. The battery charger was not started, and the battery capacity decreased after long-term natural discharge. The charger used needs to be charged and replaced manually and regularly. The battery power cannot meet the requirements due to ignoring the replacement operation. To solve this problem, in addition to configuring high-quality chargers, necessary inspection and maintenance are also required.

2.水进入沼气发电机组，空气中的水蒸气因温度变化而凝结，形成水滴附着在油箱内壁，流入柴油中，柴油的含水量超标。这种柴油进入发动机的高压油泵，被精确切割。

2. When water enters the biogas generator set, the water vapor in the air condenses due to temperature change, forming water droplets attached to the inner wall of the oil tank, and flowing into the diesel oil, the water content of the diesel oil exceeds the standard. This diesel enters the high-pressure oil pump of the engine and is precisely cut.

3.机油的质保期(两年)是机械润滑，但是机油也有一定的质保期。机油长期存放后，其理化性质会发生变化，导致机组在运行中润滑条件恶化，容易导致机组零部件损坏。润滑油将定期更换。

3. The warranty period of engine oil (two years) is mechanical lubrication, but engine oil also has a certain warranty period. After long-term storage, the physical and chemical properties of the engine oil will change, resulting in the deterioration of the lubricating conditions of the unit during operation, and easy to cause damage to the unit components. The lubricating oil will be changed regularly.

4.三个过滤更换周期(柴油过滤、机器过滤、空气过滤和水过滤)。过滤器可以过滤柴油、机油或水，防止杂质进入体内。柴油中的油渍和杂质是不可避免的，因此滤清器在机组的运行中起着重要的作用，但同时这些油渍或杂质也堆积在滤清器壁上，降低了滤清器的过滤能力，堆积过度。所以油路就成了油机的备用单元，每两年更换一次。

4. Three filter replacement cycles (diesel filter, machine filter, air filter and water filter). The filter can filter diesel, oil or water to prevent impurities from entering the body. Oil stains and impurities in diesel oil are inevitable, so the filter plays an important role in the operation of the unit, but at the same time, these oil stains or impurities also accumulate on the filter wall, reducing the filter capacity and excessive accumulation. Therefore, the oil circuit becomes the standby unit of the oil engine, which is replaced every two years.

5.如果冷却系统、水泵、水箱、水管长期不冲洗，水循环不畅，冷却效果下降，管接头是否完好，水箱、自来水是否漏水，冷却效果差。即使因漏水导致水箱水位下降，机组也无法正常运行。冬季使用发电机时，建议在冷却系统中安装热水器，以防水管结冰。

5. If the cooling system, water pump, water tank and water pipe are not flushed for a long time, the water circulation is not smooth, the cooling effect is reduced, the pipe joint is intact, the water tank and tap water are leaky, and the cooling effect is poor. Even if the water level in the water tank drops due to water leakage, the unit cannot operate normally. When using the generator in winter, it is recommended to install a water heater in the cooling system to prevent water pipes from freezing.

沼气发电机组的控制部分和油机的控制部分也是机组维护的重要部分。机组使用时间过长，线路接头是否松动，AVR模块是否正常工作。更多相关内容就来我们网站//www.gz-yanye.com进行咨询！

The control part of biogas generator unit and the control part of oil engine are also important parts of unit maintenance. The unit has been used for a long time, whether the line connector is loose, and whether the AVR module works normally. Come to our website for more relevant content //www.gz-yanye.com Consult!
