良好的維護(hù)與保養(yǎng)能保證機(jī)組可靠運(yùn)行。正常使用情況下，合金尾氣發(fā)電機(jī)組的保養(yǎng)工作應(yīng)按規(guī)定的日保養(yǎng)、周保養(yǎng)、月保養(yǎng)要求進(jìn)行。通過這些規(guī)定的保養(yǎng)，能及時(shí)發(fā)現(xiàn)機(jī)組是否存在聲音異常、動(dòng)作異常、外觀異常、溫度異常、壓力異常和氣味異常等故障現(xiàn)象，從而及時(shí)對(duì)機(jī)組進(jìn)行檢查和調(diào)整，進(jìn)而有針對(duì)性的加以解決,確保機(jī)組正常運(yùn)行。

　　Good maintenance and upkeep can ensure the reliable operation of the unit. Under normal use, the maintenance of the alloy exhaust gas generator set should be carried out according to the prescribed daily, weekly, and monthly maintenance requirements. Through these prescribed maintenance procedures, it is possible to promptly detect any abnormal sounds, movements, appearances, temperatures, pressures, odors, or other malfunctions in the unit. This enables timely inspection and adjustment of the unit, and targeted solutions to ensure its normal operation.

　　在這些保養(yǎng)要求中，要特別注意以下三個(gè)方面的檢查和保養(yǎng)：

　　Among these maintenance requirements, special attention should be paid to the following three aspects of inspection and maintenance:

　　(1) 潤(rùn)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(rùn)滑的部位較多，對(duì)潤(rùn)滑系統(tǒng)的可靠性要求較為苛刻，因此要注意檢查潤(rùn)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(rùn)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 numerous operating components and harsh working conditions of the unit, most of which are under high temperature and high impact loads, there are many parts that require lubrication, and the reliability requirements for the lubrication system are quite strict. Therefore, attention should be paid to checking the oil quality, oil level, oil temperature, and oil pressure of the lubrication system, and cleaning the centrifugal filter and oil filter to avoid increased wear of the unit components caused by poor lubrication and shorten the service life of the 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(shí)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 prevent 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 reduced flow. Therefore, it is necessary to regularly clean the air filter and replace the filter element if necessary. In humid areas, the paper filter can be removed.

　　(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(shí)等的檢查和調(diào)整。

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

　　合金尾氣發(fā)電機(jī)組運(yùn)行一段時(shí)間后，火花塞的間隙會(huì)有所變大，這是正?，F(xiàn)象。若間隙增大到0.89mm時(shí)，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(shí)消除火花塞及其螺紋處出現(xiàn)的積炭,確保其好用。

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

　　另外，合金尾氣發(fā)電機(jī)組經(jīng)長(zhǎng)時(shí)間運(yùn)轉(zhuǎn)后，由于配氣機(jī)構(gòu)的磨損和松動(dòng)等原因，會(huì)引起氣門間隙的變化,應(yīng)定期檢查并調(diào)整氣門間隙。配氣定時(shí)在正常情況下不需要進(jìn)行調(diào)整，當(dāng)機(jī)組各缸工作狀態(tài)出現(xiàn)異常時(shí)，應(yīng)首先檢查指針上止點(diǎn)指示位置是否正確，檢查傳動(dòng)系統(tǒng)各齒輪傳動(dòng)記號(hào)是否對(duì)準(zhǔn)，整個(gè)系統(tǒng)的裝配關(guān)系及氣門間隙是否正確。若經(jīng)檢查調(diào)整后，仍與規(guī)定值差異較大時(shí)，則應(yīng)考慮凸輪軸或齒輪傳動(dòng)件有無損壞現(xiàn)象，必要時(shí)進(jìn)行修復(fù)或更換。

　　In addition, after long-term operation, the alloy exhaust gas generator set may experience changes in valve clearance due to wear and looseness of the valve mechanism, and the valve clearance should be regularly checked and adjusted. Under normal circumstances, the valve timing does not need to be adjusted. When the working status of each cylinder in the unit is abnormal, the first thing to check is whether the pointer's top dead center indication position is correct, whether the transmission marks of each gear in the transmission system are aligned, and whether the assembly relationship and valve clearance of the entire system are correct. If there is still a significant difference from the specified value after inspection and adjustment, the camshaft or gear transmission components should be considered for damage and repaired or replaced if necessary.
