1)环境温度过低，气温较低时，请做好柴油发动机的预热，否则，很难启动。

1) When the ambient temperature is too low, please preheat the diesel engine properly, otherwise it will be difficult to start.

2)启动转速低，对于手动起动的柴油发动机，请逐渐提高转速，然后将减压手柄置于非减压位置，使气缸内有正常的压缩，如果减压机构调整错误，或者阀门碰到活塞，摇车往往很费劲。 其特点是曲轴转动到某个部位就不转了，但可以退回。 此时，除了检查减压机构外，还需要确认正时齿轮的啮合关系是否正确。 另一方面，在使用电动起动器的柴油发动机的情况下，如果起动转速极慢，起动器往往无能为力，并不表示柴油发动机本身有故障，对电路进行详细检查，判断电池是否充分充电，各导线连接是否牢固，起动器是否正常工作。

2) The starting speed is low. For manually started diesel engines, please gradually increase the speed and then place the pressure reducing handle in a non pressure reducing position to ensure normal compression in the cylinder. If the pressure reducing mechanism is adjusted incorrectly or the valve touches the piston, it is often difficult to shake the car. Its characteristic is that the crankshaft stops rotating when it reaches a certain position, but can be retracted. At this point, in addition to checking the pressure reducing mechanism, it is also necessary to confirm whether the meshing relationship of the timing gear is correct. On the other hand, in the case of a diesel engine using an electric starter, if the starting speed is extremely slow and the starter is often powerless, it does not mean that the diesel engine itself has a malfunction. A detailed inspection of the circuit should be conducted to determine whether the battery is fully charged, whether the wires are securely connected, and whether the starter is working properly.

沼气发电机组工作时产生的热水通过发电机出水管到达换热管，被来自冷水池的冷水冷却，沼气发电机组循环热水水温下降后，返回柴油发动机油箱，在油箱再次冷却后，流向柴油发动机，冷却柴油发电机。

The hot water generated during the operation of the biogas generator unit reaches the heat exchange pipe through the generator outlet pipe and is cooled by cold water from the cold water pool. After the circulating hot water temperature of the biogas generator unit drops, it returns to the diesel engine oil tank. After the oil tank cools again, it flows to the diesel engine to cool the diesel generator.

冷水池冷水经过滤后，由泵送换热器，冷却柴油发电机循环热水后，水温上升，送温水池，温水池和冷水池相互隔离，只需在中间隔离壁上开设溢流孔，生活热水用量少时，温水池热水通过溢流孔流向冷水池，冷水池水位由补水水位启动阀自动控制，水位控制阀控制水位低于溢流孔位200mm，生活热水用量大时，冷却池水位。

After the cold water in the cold water pool is filtered, it is pumped to a heat exchanger to cool the diesel generator. After circulating hot water, the water temperature rises. The warm water pool, warm water pool, and cold water pool are isolated from each other, and only an overflow hole needs to be opened on the middle isolation wall. When the amount of domestic hot water is low, the hot water in the warm water pool flows to the cold water pool through the overflow hole. The water level in the cold water pool is automatically controlled by the makeup water level starting valve, and the water level control valve controls the water level to be 200mm lower than the overflow hole position, When the amount of domestic hot water is large, the water level in the cooling pool is affected.

同时，工业不断发展，工业有机废水排放量也十分惊人，考虑到酒糟液、城市垃圾填埋、污水处理沼气等因素，我国沼气资源潜力进一步扩大，沼气发电前景十分广阔。 同时，我国广大农村生物质能资源十分丰富，解决农村电气化，沼气发电是重要途径，而大中型沼气工程和沼气发电工程一次性投资费用相当大，沼气工程投资费用是沼气发电工程的4倍左右，只有在推进沼气工程应用的同时，继续研究，提高沼气池的产气率，积极推进沼气发电工程的应用，才能在尽可能保持社会效益不变的前提下，持续提高经济效益，大大提高整个工程的一次性投资回报。

At the same time, with the continuous development of industry, the discharge of industrial organic wastewater is also astonishing. Considering factors such as distiller's grains, urban garbage landfill, and sewage treatment biogas, the potential of biogas resources in China has further expanded, and the prospects for biogas power generation are very broad. At the same time, China's vast rural areas are rich in biomass energy resources, and biogas power generation is an important way to solve rural electrification. However, the one-time investment cost of large and medium-sized biogas projects and biogas power generation projects is quite high, and the investment cost of biogas projects is about four times that of biogas power generation projects. Only when promoting the application of biogas projects, continue to research and improve the gas production rate of biogas tanks, and actively promote the application of biogas power generation projects, Only by maintaining the same social benefits as much as possible, can we continuously improve economic benefits and greatly increase the one-time investment return of the entire project.

沼气发电工程是一项节能环保的工程，造福全社会，基于目前沼气发电工程还存在的问题，工程须由政府、地方和企业共同出资组建。 对尚处于起步阶段的新兴环境保护项目，国家要给予一定的支持。 例如，政府要制定一系列优惠政策，减免工程费用，减轻企业负担。 行业应当广泛提供资金渠道，帮助建设方获得各类贷款; 同时加大宣传力度，鼓励社会各界多种形式投资开发沼气发电项目，用优惠政策调动各投资主体积极性。

The biogas power generation project is an energy-saving and environmentally friendly project that benefits the entire society. Based on the existing problems of biogas power generation projects, the project must be jointly funded and established by the government, local governments, and enterprises. The state should provide certain support to emerging environmental protection projects that are still in their early stages. For example, the government should formulate a series of preferential policies to reduce engineering costs and reduce the burden on enterprises. The industry should provide extensive funding channels to help construction companies obtain various types of loans; At the same time, we will increase publicity efforts, encourage various forms of investment and development in biogas power generation projects from all sectors of society, and use preferential policies to mobilize the enthusiasm of various investment entities.
