1、沼氣發(fā)電機(jī)組啟動(dòng)電池故障，電池長(zhǎng)時(shí)間未維修。 電解液水分揮發(fā)后，不能立即補(bǔ)充。 沒有配置啟動(dòng)電池充電器，電池長(zhǎng)時(shí)間自然放電后電量下降，使用的充電器需要人工定期進(jìn)行均充更換。 由于疏于更換操作，蓄電池電量達(dá)不到要求，解決此問(wèn)題除配置高質(zhì)量充電器外，還需要必要的檢查維護(hù)。

1. The start-up battery of the biogas generator set has malfunctioned and the battery has not been repaired for a long time. After the electrolyte moisture evaporates, it cannot be replenished immediately. There is no configuration to start the battery charger, and after a long period of natural discharge, the battery level drops. The charger used needs to be manually replaced regularly for even charging. Due to negligence in replacement operations, the battery level does not meet the requirements. To solve this problem, in addition to configuring a high-quality charger, necessary inspection and maintenance are also required.

2、水進(jìn)入柴油發(fā)動(dòng)機(jī)，空氣中水氣因溫度變化發(fā)生冷凝現(xiàn)象，結(jié)成水珠附著在油箱內(nèi)壁，流入柴油，柴油含水量超標(biāo)，此類柴油進(jìn)入發(fā)動(dòng)機(jī)高壓油泵，精密切割。

2. Water enters the diesel engine, and the water vapor in the air condenses due to temperature changes, forming water droplets that adhere to the inner wall of the fuel tank and flow into the diesel. The water content of the diesel exceeds the standard, and this type of diesel enters the high-pressure oil pump of the engine for precise cutting.

3、機(jī)油保用期(兩年)動(dòng)機(jī)油是機(jī)械潤(rùn)滑作用，但機(jī)油也有一定的保用期，長(zhǎng)時(shí)間儲(chǔ)存后，機(jī)油的物理化學(xué)性能會(huì)發(fā)生變化，導(dǎo)致機(jī)組運(yùn)行時(shí)潤(rùn)滑狀況惡化，容易引起機(jī)組零部件損壞，潤(rùn)滑油定期更換。

3. The warranty period of engine oil (two years) is for mechanical lubrication, but engine oil also has a certain warranty period. After long-term storage, the physical and chemical properties of engine oil will change, leading to deterioration of lubrication conditions during unit operation, which can easily cause damage to unit components. Lubricating oil should be replaced regularly.

4、三過(guò)濾更換周期(柴過(guò)濾、機(jī)過(guò)濾、空過(guò)濾、水過(guò)濾)，過(guò)濾器起到過(guò)濾柴油、機(jī)油或水的作用，防止雜質(zhì)進(jìn)入機(jī)體內(nèi)。 柴油中油污、雜質(zhì)也是不可避免的存在，因此在機(jī)組運(yùn)行過(guò)程中，過(guò)濾器起著重要的作用，但同時(shí)這些油污或雜質(zhì)也堆積在過(guò)濾壁上，降低了過(guò)濾器的過(guò)濾能力，堆積過(guò)度，油路由此成為油機(jī)的備用機(jī)組每?jī)赡旮鼡Q一次。

4. Three filter replacement cycles (diesel filter, machine filter, air filter, water filter), the filter plays a role in filtering diesel, engine oil, or water, preventing impurities from entering the engine body. Oil pollution and impurities are also inevitable in diesel, so filters play an important role in the operation of the unit. However, at the same time, these oil pollutants or impurities also accumulate on the filter wall, reducing the filtering ability of the filter and causing excessive accumulation. As a result, the oil circuit becomes a backup unit for the oil engine, which is replaced every two years.

5、冷卻系統(tǒng)、水泵、水箱及輸水管道長(zhǎng)時(shí)間不沖洗，水循環(huán)不暢，冷卻效果下降，管接頭是否良好，水箱、自來(lái)水是否漏水等冷卻系統(tǒng)出現(xiàn)故障，導(dǎo)致冷卻效果較差，機(jī)組即使水箱漏水導(dǎo)致水箱內(nèi)水位下降，機(jī)組也不能正常動(dòng)作。 (冬季使用發(fā)電機(jī)時(shí)，建議在冷卻系統(tǒng)中安裝水加熱器，以免水管凍結(jié)。

5. If the cooling system, water pump, water tank, and water delivery pipeline are not flushed for a long time, the water circulation is not smooth, the cooling effect decreases, the pipe joints are good, and the water tank and tap water are leaking, the cooling system malfunctions, resulting in poor cooling effect. 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.

6、潤(rùn)滑系統(tǒng)、密封，由于潤(rùn)滑油或油脂的化學(xué)特性和機(jī)械磨損后產(chǎn)生的鐵屑，它們不僅降低了潤(rùn)滑效果，而且加速了零件的損傷，同時(shí)由于潤(rùn)滑油對(duì)橡膠墊有一定的腐蝕作用。

6. Lubrication systems and seals, due to the chemical properties of lubricating oil or grease and the iron filings generated after mechanical wear, not only reduce lubrication effectiveness, but also accelerate part damage. At the same time, lubricating oil has a certain corrosive effect on rubber pads.

7、燃料、閥門系統(tǒng)、發(fā)動(dòng)機(jī)功率主要由燃料在缸內(nèi)燃燒做功，由于燃料通過(guò)噴油嘴噴出，燃燒后的沉積物堆積在噴油嘴上，隨著堆積量的增加，噴油嘴噴射量受到一定的影響，噴油嘴點(diǎn)火提前時(shí)間不均勻因此，燃料系統(tǒng)定期清洗、過(guò)濾部件的更換、油供給變得順暢，能夠向閥系統(tǒng)進(jìn)行調(diào)整。

7. The fuel, valve system, and engine power are mainly powered by the combustion of fuel in the cylinder. As the fuel is sprayed out through the fuel injector, the sediment after combustion accumulates on the injector. As the accumulation increases, the injection amount of the injector is affected to a certain extent, and the ignition advance time of the injector is uneven. Therefore, the fuel system is regularly cleaned, filter components are replaced, and the oil supply becomes smooth, which can be adjusted to the valve system.

8、沼氣發(fā)電機(jī)組控制部分、油機(jī)控制部分也是機(jī)組維護(hù)的重要部分，機(jī)組使用過(guò)長(zhǎng)，線路接縫松動(dòng)，AVR模塊是否正常工作。

8. The control part of the biogas generator unit and the control part of the oil engine are also important parts of unit maintenance. If the unit is used too long, the line joints are loose, and whether the AVR module is working properly.
