沼氣發(fā)電機組的大修和小修是發(fā)電機組維護和保養的兩種不同形式。它們的區別在于時(shí)間、范圍和維護內容的不同。以下是它們的詳細說(shuō)明：

The major and minor repairs of biogas generator sets are two different forms of maintenance and upkeep for generator sets. Their difference lies in the time, scope, and maintenance content. Here are their detailed explanations:

　　小修：也稱(chēng)為日常保養，通常是指對發(fā)電機組進(jìn)行定期的、較為簡(jiǎn)單的維修和保養。小修一般是每隔一定時(shí)間對發(fā)電機組進(jìn)行檢查和保養，例如每個(gè)月、每個(gè)季度或每半年進(jìn)行一次。小修的主要內容包括：

Minor maintenance: also known as daily maintenance, usually refers to regular and relatively simple maintenance and upkeep of the generator set. Minor repairs usually involve inspecting and maintaining the generator set at regular intervals, such as once a month, every quarter, or every six months. The main contents of minor repairs include:

　　更換機油和機油濾清器；

Replace the engine oil and oil filter;

　　更換空氣濾清器和燃油濾清器；

Replace the air filter and fuel filter;

　　檢查和更換火花塞和點(diǎn)火線(xiàn)圈；

Check and replace spark plugs and ignition coils;

　　檢查和清潔發(fā)電機組的冷卻系統和燃料系統；

Inspect and clean the cooling and fuel systems of the generator set;

　　檢查和更換發(fā)電機組的電池；

Check and replace the battery of the generator set;

　　檢查電纜和接線(xiàn)板，確保電纜和接線(xiàn)板沒(méi)有損壞或老化。

Check the cables and terminal blocks to ensure that they are not damaged or aged.

　　大修：也稱(chēng)為維修保養，通常是指對沼氣發(fā)電機組進(jìn)行全面的、深度的維修和保養。大修一般是每隔一定時(shí)間或在發(fā)電機組使用壽命到達后進(jìn)行一次。大修的主要內容包括：

Major repair: also known as maintenance and upkeep, usually refers to comprehensive and in-depth maintenance and upkeep of biogas generator units. Major repairs are generally carried out at regular intervals or after the service life of the generator set has reached its limit. The main contents of major repairs include:

　　拆卸和檢查發(fā)電機組的每個(gè)部件，包括引擎、發(fā)電機、控制系統等；

Disassemble and inspect every component of the generator set, including the engine, generator, control system, etc;

　　更換或修復發(fā)電機組的所有損壞或老化的部件；

Replace or repair all damaged or aged components of the generator set;

　　清洗發(fā)電機組的所有部件，包括冷卻系統、燃料系統、電纜和接線(xiàn)板等；

Clean all components of the generator set, including the cooling system, fuel system, cables, and wiring boards;

　　完成大修后，需要對發(fā)電機組進(jìn)行全面的測試和調整，確保發(fā)電機組的性能符合標準。

After completing the major overhaul, it is necessary to conduct comprehensive testing and adjustment of the generator set to ensure that its performance meets the standards.
