瓦斯發(fā)電機組的穩(wěn)定運行依賴于科學的保養(yǎng)體系，合理規(guī)劃保養(yǎng)方法與周期，能有效降低故障發(fā)生率，延長設(shè)備使用壽命。保養(yǎng)需覆蓋發(fā)動機、瓦斯系統(tǒng)、電氣系統(tǒng)等核心部件，結(jié)合使用頻率與運行環(huán)境制定針對性方案。

　　The stable operation of gas generator units relies on a scientific maintenance system. Reasonable planning of maintenance methods and cycles can effectively reduce the occurrence of failures and extend the service life of equipment. Maintenance should cover core components such as the engine, gas system, and electrical system, and develop targeted plans based on usage frequency and operating environment.

　　發(fā)動機的保養(yǎng)是設(shè)備穩(wěn)定運行的基礎(chǔ)。每次啟動前需檢查機油液位與質(zhì)量，若機油乳化或雜質(zhì)過多，需立即更換，避免潤滑不良導致部件磨損，更換周期通常為運行 500 小時或 3 個月（以先到者為準）。冷卻系統(tǒng)需每周檢查冷卻液液位，確保在規(guī)定刻度范圍內(nèi)，每運行 1000 小時需更換冷卻液，并清洗水箱內(nèi)部的水垢，防止散熱效率下降。空氣濾清器需根據(jù)環(huán)境粉塵濃度定期清潔，粉塵較多的場所每 200 小時清理一次，清潔 3 次后更換新濾芯；正常環(huán)境下可每 500 小時更換，避免灰塵進入氣缸加劇活塞磨損。火花塞或點火電極需每 300 小時檢查一次，清理積碳并調(diào)整間隙，磨損嚴重時及時更換，保證點火效率。

　　The maintenance of the engine is the foundation for the stable operation of the equipment. Before each start-up, the oil level and quality should be checked. If the oil is emulsified or has too many impurities, it should be replaced immediately to avoid component wear caused by poor lubrication. The replacement cycle is usually 500 hours of operation or 3 months (whichever comes first). The cooling system needs to check the coolant level weekly to ensure it is within the specified range. The coolant should be replaced every 1000 hours of operation and the scale inside the water tank should be cleaned to prevent a decrease in heat dissipation efficiency. The air filter needs to be cleaned regularly according to the environmental dust concentration. For places with a lot of dust, it should be cleaned every 200 hours and replaced with a new filter element after cleaning three times; Under normal circumstances, it can be replaced every 500 hours to prevent dust from entering the cylinder and exacerbating piston wear. Spark plugs or ignition electrodes should be checked every 300 hours to clean carbon deposits and adjust clearances. If they are severely worn, they should be replaced in a timely manner to ensure ignition efficiency.

　　瓦斯供應系統(tǒng)的保養(yǎng)關(guān)乎運行安全與效率。每日需檢查瓦斯管路的密封性，用肥皂水涂抹接口處，觀察是否有氣泡產(chǎn)生，若發(fā)現(xiàn)泄漏需立即停機檢修，更換密封件或緊固接頭。瓦斯過濾器需每 150 小時清理一次濾網(wǎng)，去除附著的雜質(zhì)與水分，防止堵塞導致供氣不足，每 600 小時更換過濾器濾芯，確保瓦斯純度。減壓穩(wěn)壓閥需每月校準一次，通過壓力計檢測輸出壓力，使其穩(wěn)定在設(shè)備規(guī)定范圍內(nèi)（通常為 5-10kPa），避免壓力波動影響燃燒效率。此外，每運行 200 小時需檢查瓦斯噴嘴的通暢性，用專用工具清理堵塞物，保證霧化效果均勻。

　　The maintenance of the gas supply system is related to operational safety and efficiency. Check the sealing of the gas pipeline daily, apply soapy water to the interface, and observe whether bubbles are generated. If a leak is found, immediately stop the machine for maintenance, replace the seal or tighten the joint. Gas filters need to be cleaned every 150 hours to remove attached impurities and moisture, prevent blockages that may cause insufficient gas supply, and replace filter cartridges every 600 hours to ensure gas purity. The pressure reducing and stabilizing valve needs to be calibrated once a month, and the output pressure is detected by a pressure gauge to stabilize it within the specified range of the equipment (usually 5-10kPa), avoiding pressure fluctuations that affect combustion efficiency. In addition, the patency of the gas nozzle should be checked every 200 hours of operation, and special tools should be used to clean blockages to ensure uniform atomization effect.

　　電氣系統(tǒng)的保養(yǎng)需注重絕緣與連接可靠性。每周檢查電纜接頭是否松動、過熱，發(fā)現(xiàn)燒灼痕跡需立即處理，重新緊固或更換接頭，避免接觸不良引發(fā)電路故障。蓄電池需每 15 天檢查一次電量，電壓低于 12V 時及時充電，電極樁頭若有氧化物需用熱水沖洗并涂抹凡士林，防止腐蝕。控制柜內(nèi)部需每月除塵一次，用干燥壓縮空氣吹掃線路板與元器件，避免粉塵堆積導致短路，同時檢查繼電器、接觸器的觸點狀態(tài)，出現(xiàn)燒蝕時進行打磨或更換，確保電氣元件動作靈敏。

　　The maintenance of electrical systems should pay attention to insulation and connection reliability. Check the cable joints for looseness and overheating every week. If burn marks are found, they should be dealt with immediately, and the joints should be re tightened or replaced to avoid poor contact and circuit failure. The battery should be checked for power every 15 days, and charged promptly when the voltage is below 12V. If there is oxide on the electrode post, it should be rinsed with hot water and coated with Vaseline to prevent corrosion. The interior of the control cabinet needs to be dusted once a month, and the circuit board and components should be blown with dry compressed air to avoid short circuits caused by dust accumulation. At the same time, the contact status of relays and contactors should be checked, and if there is erosion, they should be polished or replaced to ensure the sensitivity of electrical components.

　　輔助系統(tǒng)的定期保養(yǎng)不可忽視。潤滑系統(tǒng)的齒輪箱需每 800 小時更換齒輪油，放油時徹底排空舊油并清洗油底殼，加注新油至規(guī)定液位，防止齒輪因潤滑不足產(chǎn)生異響或磨損。排煙系統(tǒng)需每 300 小時檢查排氣管路的密封性，清理內(nèi)部積碳，避免堵塞導致排氣背壓升高，影響發(fā)動機功率。減振裝置需每 6 個月檢查一次，若橡膠墊老化或彈簧失效，需及時更換，減少設(shè)備運行時的振動對部件連接的影響。

　　The regular maintenance of auxiliary systems cannot be ignored. The gearbox of the lubrication system needs to replace the gear oil every 800 hours, thoroughly drain the old oil and clean the oil pan when draining, and add new oil to the specified level to prevent abnormal noise or wear of the gears due to insufficient lubrication. The exhaust system needs to check the sealing of the exhaust pipe every 300 hours, clean the internal carbon deposits, and avoid blockages that may cause an increase in exhaust back pressure and affect engine power. The vibration reduction device needs to be checked every 6 months. If the rubber pad ages or the spring fails, it should be replaced in a timely manner to reduce the impact of vibration during equipment operation on component connections.

　　保養(yǎng)周期需根據(jù)運行強度動態(tài)調(diào)整。連續(xù)運行的機組（如每天運行 10 小時以上）需縮短保養(yǎng)間隔，例如機油更換周期可縮短至 400 小時；間歇運行的機組，即使未達到規(guī)定運行時間，每 6 個月也需進行一次全面保養(yǎng)，防止部件因長期閑置出現(xiàn)銹蝕或老化。惡劣環(huán)境（如高溫、高濕度、多粉塵場所）中的機組，需增加濾清器清潔頻率，每月額外進行一次管路密封性檢查，確保設(shè)備適應環(huán)境條件。

　　The maintenance cycle needs to be dynamically adjusted according to the operating intensity. Continuous operation of the unit (such as running for more than 10 hours per day) requires a shorter maintenance interval, for example, the oil change cycle can be shortened to 400 hours; Intermittent units, even if they have not reached the specified operating time, require comprehensive maintenance every 6 months to prevent components from rusting or aging due to long-term idle. Units in harsh environments (such as high temperature, high humidity, and dusty areas) need to increase the frequency of filter cleaning and conduct an additional monthly pipeline sealing inspection to ensure that the equipment is suitable for environmental conditions.
