20年以上

　　Over 20 years

　　沼氣發電機組的使用壽命一般在20年以上，一年實際上網發電時間在7200小時以上。

　　The service life of biogas generators is generally over 20 years, and the actual online power generation time is over 7200 hours per year.

　　需要注意的是，沼氣發電機組的實際使用壽命會受到多種因素的影響，包括工作環境、使用與維護情況、設計與制造質量、燃料品質以及負載管理等。例如，工作環境中的粉塵和腐蝕性氣體會影響機組壽命；超負荷運行、維護不當和操作不當也會導致機組性能下降或故障；燃料中的雜質會影響燃燒效率和運行穩定性；負載過大可能導致發電機組過載，影響其穩定運行和壽命。因此，為了延長沼氣發電機組的壽命，需要綜合考慮并優化這些因素。相比之下，水電站發電機組的使用壽命一般為40-50年。

　　It should be noted that the actual service life of biogas generators will be affected by various factors, including working environment, usage and maintenance, design and manufacturing quality, fuel quality, and load management. For example, dust and corrosive gases in the work environment can affect the lifespan of the unit; Overloading operation, improper maintenance, and improper operation can also lead to a decrease in unit performance or failure; Impurities in fuel can affect combustion efficiency and operational stability; Excessive load may cause the generator set to overload, affecting its stable operation and lifespan. Therefore, in order to extend the lifespan of biogas generators, it is necessary to comprehensively consider and optimize these factors. In contrast, the service life of hydroelectric power generation units is generally 40-50 years.

　　以下是20年以上沼氣發電機組的常見故障：

　　The following are common faults of biogas generators over 20 years old:

　　1. 啟動困難：可能由于混合器未調節好、火花塞不顯火、點火時間不準、沼氣質量不佳、燃燒室密封不良、沼氣供給系統故障、12V電源系統問題等導致。

　　1. Difficulty in starting: This may be due to improper adjustment of the mixer, failure to ignite the spark plug, inaccurate ignition time, poor quality of biogas, poor sealing of the combustion chamber, malfunction of the biogas supply system, problems with the 12V power supply system, etc.

　　2. 動力下降：可能由于氣缸漏氣、氣門間隙不正常、沼氣動力閥間隙太小、沼氣過濾器堵塞、壓力平衡管漏氣、增壓中冷系統漏氣、排氣管道或三元催化器堵塞、混合器皮膜破損、減壓器電磁閥閥芯或閥孔破損等原因導致。

　　2. Decreased power: It may be caused by cylinder leakage, abnormal valve clearance, too small clearance of biogas power valve, blockage of biogas filter, leakage of pressure balance pipe, leakage of boost intercooler system, blockage of exhaust pipe or three-way catalyst, damage of mixer film, damage of pressure reducer solenoid valve core or valve hole, and other reasons.

　　3. 耗氣量高：可能由于水溫過低、高低壓沼氣管線、混合器與節氣門連接處、進氣管、沼氣裝置及鋼瓶漏氣、空氣濾清器不干凈、混合器流量調整不當、減壓器出口壓力高、低壓減壓器輸出壓力過高、點火系統故障等原因導致。

　　3. High gas consumption: It may be caused by low water temperature, high and low pressure biogas pipelines, mixer and throttle valve connections, intake pipes, biogas devices and steel cylinders leaking air, unclean air filters, improper adjustment of mixer flow, high outlet pressure of pressure reducers, high output pressure of low-pressure pressure reducers, ignition system failures, and other reasons.

　　4. 熱車不易啟動：可能由于電磁閥過熱、電控插頭接觸不良、混合器閥芯卡滯、減壓器輸出壓力過高、受溫度影響的部件故障等原因導致。

　　4. Difficulty starting a hot car: This may be due to overheating of the solenoid valve, poor contact of the electronic control plug, stuck valve core of the mixer, high output pressure of the pressure reducer, and component failures affected by temperature.

　　5. 電磁閥打不開：可能由于電源未接通、電磁閥搭鐵不好、電壓過低、磁線圈故障、閥芯通氣孔被堵、ECU無輸出控制信號、閥芯和鐵心的配合間隙太小、閥芯O形圈或橡膠墊損壞等原因導致。

　　5. Electromagnetic valve cannot be opened: This may be due to reasons such as power failure, poor grounding of the solenoid valve, low voltage, magnetic coil failure, blocked valve core vent hole, ECU no output control signal, small clearance between the valve core and iron core, damaged valve core O-ring or rubber gasket, etc.

　　6. 怠速不穩：雖然搜索結果中未詳細說明，但這是沼氣發電機組常見的故障之一。

　　6. Unstable idle speed: Although not detailed in the search results, this is one of the common faults in biogas generators.

　　以上故障可能因設備老化、維護不當或使用環境惡劣而加劇。定期維護和檢查是確保沼氣發電機組正常運行的關鍵。如果遇到上述問題，建議及時聯系專業技術人員進行檢修。

　　The above faults may be exacerbated by equipment aging, improper maintenance, or harsh usage environments. Regular maintenance and inspection are key to ensuring the normal operation of biogas generators. If encountering the above problems, it is recommended to contact professional technicians for maintenance in a timely manner.
