The biogas generator set needs correct operation and daily maintenance to help extend its service life without hindering its normal use. Here are the factors that affect the service life of the generator: if we choose the biogas generator set using environment-friendly fuels, we need correct operation and daily maintenance to help extend its service life without hindering its normal use.

1、工作环境清洁程度，如多粉尘等；易造成空气滤芯堵塞，发动机散热片堵塞，造成发动机高温；

1. Cleanliness of working environment, such as excessive dust; It is easy to block the air filter element and the engine radiator, causing high engine temperature;

2、发动机使用时间，超负荷疲劳工作，造成发动机零部件过度磨损；

2. Engine service time and overload fatigue work cause excessive wear of engine parts;

3、发动机的温度，突加大油门，润滑系统没正常工作，易造成发动机零部件快速磨损；

3. The temperature of the engine, the sudden increase of the throttle, and the lubrication system do not work properly, which are easy to cause rapid wear of engine parts;

4、润滑油质量，润滑质量无法满足发动机的工作需要，造成发动机早期磨损；

4. The quality of lubricating oil and lubricating quality can not meet the working needs of the engine, resulting in early wear of the engine;

5、燃料的纯洁程度，容易造成喷嘴积碳烧死，活塞顶部积碳，气门座圈积碳，发动机燃烧系统密封不良，动力性能下降等

5. The purity of the fuel is easy to cause carbon deposition on the nozzle to burn, carbon deposition on the top of the piston, carbon deposition on the valve seat ring, poor sealing of the engine combustion system, poor power performance, etc

6、日常维护保养程度，按照正常的保养，做好记录，才能有助于延长使用时间，保护沼气发电机组发电机的正常使用。

6. The degree of daily maintenance shall be recorded according to the normal maintenance, which can help to extend the service time and protect the normal use of the biogas generator set generator.
