沼氣發電機組是電故障和停電后應急備用電源的提供者。大部分時間，沼氣發電機組處于備用狀態。萬一停電，沼氣發電機組無法緊急啟動，那么后備單位就失去了意義。實踐證明，加強日常維護是一種經濟有效的方法。

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.沼氣發電機組啟動電池故障，電池長時間未維修。電解液蒸發后，不能立即補充。沒有啟動電池充電器，長期自然放電后電池容量下降。使用的充電器需要手動定期充電和更換。由于忽視更換操作，電池電量達不到要求。要解決這個問題，除了配置高質量的充電器，還需要必要的檢查和維護。

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.水進入沼氣發電機組，空氣中的水蒸氣因溫度變化而凝結，形成水滴附著在油箱內壁，流入柴油中，柴油的含水量超標。這種柴油進入發動機的高壓油泵，被精確切割。

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.機油的質保期(兩年)是機械潤滑，但是機油也有一定的質保期。機油長期存放后，其理化性質會發生變化，導致機組在運行中潤滑條件惡化，容易導致機組零部件損壞。潤滑油將定期更換。

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.

4.三個過濾更換周期(柴油過濾、機器過濾、空氣過濾和水過濾)。過濾器可以過濾柴油、機油或水，防止雜質進入體內。柴油中的油漬和雜質是不可避免的，因此濾清器在機組的運行中起著重要的作用，但同時這些油漬或雜質也堆積在濾清器壁上，降低了濾清器的過濾能力，堆積過度。所以油路就成了油機的備用單元，每兩年更換一次。

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.如果冷卻系統、水泵、水箱、水管長期不沖洗，水循環不暢，冷卻效果下降，管接頭是否完好，水箱、自來水是否漏水，冷卻效果差。即使因漏水導致水箱水位下降，機組也無法正常運行。冬季使用發電機時，建議在冷卻系統中安裝熱水器，以防水管結冰。

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.

沼氣發電機組的控制部分和油機的控制部分也是機組維護的重要部分。機組使用時間過長，線路接頭是否松動，AVR模塊是否正常工作。更多相關內容就來我們網站http://www.hdlelisa.com進行咨詢！

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 http://www.hdlelisa.com Consult!
