(1) 潤滑系統(tǒng)的檢查和保養(yǎng)。

(1) Inspection and maintenance of lubrication system.

該機(jī)組由于存在運(yùn)轉(zhuǎn)部件多，運(yùn)轉(zhuǎn)部件工作條件惡劣，大多處在高溫、高沖擊載荷狀態(tài)下，需要潤滑的部位較多，對潤滑系統(tǒng)的可靠性要求較為苛刻，因此要注意檢查潤滑油系統(tǒng)的油質(zhì)情況、油位情況、油溫和油壓情況,注意離心濾清器和機(jī)油濾清器的清洗，避免出現(xiàn)因潤滑不良造成的機(jī)組零部件磨損加劇，縮短機(jī)組零部件的使用壽命。

Due to the presence of multiple operating components and harsh working conditions, most of the operating components of the unit are in high temperature and high impact load conditions. There are many parts that require lubrication, and the reliability requirements of the lubrication system are relatively strict. Therefore, it is necessary to pay attention to checking the oil quality, oil level, oil temperature, and oil pressure of the lubrication oil system, and to clean the centrifugal filter and oil filter, To avoid intensified wear of unit components caused by poor lubrication and shorten the service life of unit components.

(2) 空氣過濾器的檢查和保養(yǎng)。

(2) Inspection and maintenance of air filters.

空氣過濾器如果運(yùn)轉(zhuǎn)良好的話，將有效地避免因進(jìn)氣阻力大引起的增壓壓力下降過大，進(jìn)而造成渦輪增壓器出現(xiàn)漏油現(xiàn)象；還可避免因流量減少引起的渦輪增壓器壓氣機(jī)喘振現(xiàn)象。因此要定期清理空氣過濾器，必要時更換新濾芯。在潮濕地區(qū)可將紙質(zhì)濾芯抽掉。

If the air filter operates well, it will effectively avoid excessive pressure drop caused by high intake resistance, which can lead to oil leakage in the turbocharger; It can also avoid the phenomenon of turbocharger compressor surge caused by flow reduction. Therefore, it is necessary to regularly clean the air filter and replace it with a new filter element if necessary. Paper filter cartridges can be removed in damp areas.

(3) 相關(guān)間隙和角度的檢查和調(diào)整。主要是火花塞間隙、氣門間隙和配氣定時等的檢查和調(diào)整。

(3) Inspection and adjustment of relevant clearances and angles. Mainly for inspection and adjustment of spark plug clearance, valve clearance, and valve timing.

燃?xì)獍l(fā)電機(jī)組運(yùn)行一段時間后，火花塞的間隙會有所變大，這是正?，F(xiàn)象。若間隙增大到0.89mm時，火花塞將出現(xiàn)失火現(xiàn)象，造成機(jī)組運(yùn)行不穩(wěn)，甚至停車，所以應(yīng)定期檢查和調(diào)整，同時消除火花塞及其螺紋處出現(xiàn)的積炭,確保其好用。

After a period of operation of the gas generator set, the gap between the spark plugs will increase, which is a normal phenomenon. If the gap increases to 0.89mm, the spark plug will catch fire, causing unstable operation of the unit and even shutdown. Therefore, regular inspection and adjustment should be carried out, and carbon deposits at the spark plug and its threads should be eliminated to ensure its usability.
