秸秆气发电机组经过长时间的工作运行之后是需要大修的。如果需要大修了还没有大修的话机组就会出现一些故障。因此，用户在使用秸秆气发电机组的时候一定要注意勤于检查机组，一旦出现异常的状况就要及时的处理。秸秆气发电机组是否要大修看看这五方面就知道了！

After a long period of operation, the straw gas generator set needs to be overhauled. If major repairs are needed but not yet done, the unit may experience some malfunctions. Therefore, users must pay attention to inspecting the straw gas generator set diligently when using it, and promptly handle any abnormal situations. Just take a look at these five aspects to determine if the straw gas generator set needs major repairs!

1、查看秸秆气发电机组在常温下的发动状况，并查看进程中曲轴轴承、连杆轴承和活塞之间是不是有敲击声，必要时进行调整校准或修正替换；

1. Check the starting condition of the straw gas generator set at room temperature, and check if there is any knocking sound between the crankshaft bearing, connecting rod bearing, and piston during the process. If necessary, adjust, calibrate, or correct replacement;

2、查看秸秆气发电机组作业时，是不是有声响骤变、排气冒黑烟等表象；

2. Check if there is a sudden change in sound or black smoke from the exhaust during the operation of the straw gas generator set;

3、检查发动机，如有损坏可对应替换气缸体、活塞、活塞环、巨细轴瓦、曲轴止推垫、进排气门、全套发动机大修包；

3. Check the engine, and if there is any damage, replace the cylinder block, piston, piston rings, large and thin bearing shells, crankshaft thrust pads, intake and exhaust valves, and a complete engine overhaul package;

4、查看秸秆气发电机组内燃机在正常作业时，气缸压力是不是到达规则压力的70%，必要时替换增压器大修包、水泵修理包；

4. Check if the cylinder pressure of the straw gas generator set's internal combustion engine reaches 70% of the regular pressure during normal operation, and replace the turbocharger overhaul kit and water pump repair kit if necessary;

5、秸秆气发电机组的大修养护同由专业修理人员履行中修养护内容后，对曲轴机体、连杆、活塞、凸轮轴等部件进行查看，视技术参数进行修理或更新，对曲轴瓦、连杆瓦、缸套、活塞环、大修包有必要替换。

5. The overhaul and maintenance of straw gas generator sets are carried out by professional repair personnel, who inspect the crankshaft body, connecting rod, piston, camshaft and other components, and repair or update them according to technical parameters. It is necessary to replace the crankshaft bearing, connecting rod bearing, cylinder liner, piston ring, and overhaul package.
