瓦斯發電機在將瓦斯能源轉化為電力的過程中，內部零件持續經受著高溫、高壓與機械摩擦的多重考驗。就像汽車需要定期保養更換零部件一樣，瓦斯發電機也有一批 “易耗品”，了解這些零件及其更換周期，是保障發電機穩定運行、延長使用壽命的關鍵。

　　During the process of converting gas energy into electricity, the internal components of a gas generator are continuously subjected to multiple tests of high temperature, high pressure, and mechanical friction. Just like cars require regular maintenance and replacement of parts, gas generators also have a batch of "consumables". Understanding these parts and their replacement cycles is the key to ensuring stable operation and extending the service life of the generator.

　　空氣濾清器是瓦斯發電機抵御雜質的首道防線，其更換頻率相對較高。在發電機運行時，空氣濾清器負責過濾進入氣缸的空氣中的灰塵、顆粒等雜質，防止它們進入發動機內部加劇零件磨損。一般來說，在較為清潔的運行環境中，空氣濾清器每運行 500 至 800 小時就需更換；若處于灰塵較多的環境，如礦區、建筑工地周邊，更換周期可能縮短至 200 至 300 小時。一旦空氣濾清器堵塞嚴重，會導致進氣量不足，發電機功率下降，油耗增加，長期不更換還可能使未經過濾的雜質進入氣缸，造成活塞、氣缸壁等重要部件的磨損。

　　The air filter is the first line of defense for gas generators to resist impurities, and its replacement frequency is relatively high. During the operation of the generator, the air filter is responsible for filtering out dust, particles, and other impurities from the air entering the cylinder, preventing them from entering the engine and exacerbating component wear. Generally speaking, in a relatively clean operating environment, the air filter needs to be replaced every 500 to 800 hours of operation; If located in dusty environments such as mining areas or construction sites, the replacement cycle may be shortened to 200 to 300 hours. Once the air filter is severely clogged, it can lead to insufficient intake air, decreased generator power, increased fuel consumption, and long-term non replacement may also allow unfiltered impurities to enter the cylinder, causing wear on important components such as the piston and cylinder wall.

　　機油濾清器的使命是過濾機油中的雜質和金屬碎屑，維持機油的清潔度和潤滑性能。機油在發動機內部循環流動，不斷潤滑各個運動部件，同時也會攜帶磨損產生的雜質。通常情況下，機油濾清器隨每次機油更換一同更換，常規的更換周期為每運行 1000 至 1500 小時。若使用的機油質量較差，或者發電機長時間在高負荷工況下運行，機油濾清器的更換時間應相應提前。否則，堵塞的機油濾清器會阻礙機油的正常流通，導致發動機潤滑不良，引發部件過度磨損，甚至出現抱軸、拉缸等嚴重故障。

　　The mission of an oil filter is to filter impurities and metal debris from engine oil, maintaining its cleanliness and lubrication performance. The engine oil circulates inside the engine, constantly lubricating various moving parts, while also carrying impurities generated by wear and tear. Normally, the oil filter is replaced with each oil change, and the regular replacement cycle is every 1000 to 1500 hours of operation. If the quality of the oil used is poor, or if the generator operates under high load conditions for a long time, the replacement time of the oil filter should be correspondingly advanced. Otherwise, a clogged oil filter will hinder the normal flow of oil, leading to poor engine lubrication, excessive component wear, and even serious malfunctions such as shaft holding and cylinder pulling.

　　火花塞作為點燃混合氣體的關鍵零件，其工作狀態直接影響發電機的點火性能和動力輸出。火花塞在高溫、高壓的燃燒環境中，電極會逐漸損耗，積碳也會不斷附著。正常工況下，火花塞每運行 2000 至 3000 小時需要更換。但如果使用的瓦斯氣體質量不佳，含有較多雜質，或者發電機存在點火不良、燃燒不充分的問題，火花塞的更換周期可能縮短至 1000 至 1500 小時。當火花塞性能下降時，會出現啟動困難、怠速不穩、功率降低等現象，及時更換火花塞才能恢復發電機的正常點火和燃燒效率。

　　As a key component for igniting mixed gases, the working state of spark plugs directly affects the ignition performance and power output of generators. Spark plugs in high-temperature and high-pressure combustion environments will gradually lose their electrodes and carbon deposits will continue to adhere. Under normal operating conditions, spark plugs need to be replaced every 2000 to 3000 hours of operation. But if the quality of the gas used is poor, contains a lot of impurities, or the generator has problems with poor ignition and insufficient combustion, the replacement cycle of spark plugs may be shortened to 1000 to 1500 hours. When the performance of spark plugs decreases, there may be difficulties in starting, unstable idling, and reduced power. Timely replacement of spark plugs is necessary to restore the normal ignition and combustion efficiency of the generator.

　　活塞環在氣缸內起著密封和導熱的重要作用，同時要承受高溫燃氣的壓力和活塞往復運動的摩擦。隨著運行時間增加，活塞環會逐漸磨損，彈性減弱，密封性能下降。一般而言，活塞環的更換周期為每運行 5000 至 8000 小時。不過，若發電機出現動力明顯下降、油耗大幅增加、排氣冒藍煙（表明機油進入燃燒室）等情況，可能意味著活塞環磨損嚴重，需提前檢查更換。活塞環磨損過度會導致氣缸壓力不足，燃氣泄漏，不僅降低發電機的發電效率，還會加速其他部件的損壞。

　　The piston ring plays an important role in sealing and conducting heat inside the cylinder, while also bearing the pressure of high-temperature gas and the friction of piston reciprocating motion. As the running time increases, the piston ring will gradually wear out, the elasticity will weaken, and the sealing performance will decrease. Generally speaking, the replacement cycle of piston rings is every 5000 to 8000 hours of operation. However, if the generator experiences a significant decrease in power, a significant increase in fuel consumption, or blue smoke from the exhaust (indicating oil entering the combustion chamber), it may indicate severe wear on the piston rings and require early inspection and replacement. Excessive wear of the piston ring can lead to insufficient cylinder pressure and gas leakage, which not only reduces the power generation efficiency of the generator, but also accelerates the damage of other components.

　　氣門油封主要防止機油進入燃燒室，避免機油消耗過多和產生積碳。長期使用后，氣門油封會因高溫和橡膠老化而失去彈性，出現密封不嚴的問題。氣門油封的更換周期通常在發電機運行 8000 至 10000 小時左右。一旦氣門油封損壞，機油會滲漏到燃燒室參與燃燒，造成機油消耗量異常增加，同時燃燒室內積碳增多，影響發電機的正常工作。

　　Valve oil seals mainly prevent oil from entering the combustion chamber, avoiding excessive oil consumption and carbon buildup. After long-term use, the valve oil seal will lose its elasticity due to high temperature and rubber aging, resulting in poor sealing. The replacement cycle of valve oil seals is usually around 8000 to 10000 hours of generator operation. Once the valve oil seal is damaged, the engine oil will leak into the combustion chamber to participate in combustion, causing an abnormal increase in oil consumption and an increase in carbon deposits in the combustion chamber, which will affect the normal operation of the generator.

　　瓦斯發電機的這些易損零件如同機器運轉的 “小齒輪”，雖不起眼卻至關重要。嚴格按照合理的更換周期對它們進行維護和更換，才能讓發電機始終保持良好的運行狀態，持續穩定地將瓦斯轉化為源源不斷的電力 。

　　These vulnerable parts of the gas generator are like the "small gears" of the machine's operation, although inconspicuous, they are crucial. Strictly maintain and replace them according to a reasonable replacement cycle in order to keep the generator in good operating condition and continuously and stably convert gas into a continuous supply of electricity.
