良好的维护与保养能保证机组可靠运行。正常使用情况下，合金尾气发电机组的保养工作应按规定的日保养、周保养、月保养要求进行。通过这些规定的保养，能及时发现机组是否存在声音异常、动作异常、外观异常、温度异常、压力异常和气味异常等故障现象，从而及时对机组进行检查和调整，进而有针对性的加以解决,确保机组正常运行。

　　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.

　　在这些保养要求中，要特别注意以下三个方面的检查和保养：

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

　　(1) 润滑系统的检查和保养。

　　(1) Inspection and maintenance of lubrication system.

　　该机组由于存在运转部件多，运转部件工作条件恶劣，大多处在高温、高冲击载荷状态下，需要润滑的部位较多，对润滑系统的可靠性要求较为苛刻，因此要注意检查润滑油系统的油质情况、油位情况、油温和油压情况,注意离心滤清器和机油滤清器的清洗，避免出现因润滑不良造成的机组零部件磨损加剧，缩短机组零部件的使用寿命。

　　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) 空气过滤器的检查和保养。

　　(2) Inspection and maintenance of air filters.

　　空气过滤器如果运转良好的话，将有效地避免因进气阻力大引起的增压压力下降过大，进而造成涡轮增压器出现漏油现象；还可避免因流量减少引起的涡轮增压器压气机喘振现象。因此要定期清理空气过滤器，必要时更换新滤芯。在潮湿地区可将纸质滤芯抽掉。

　　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) 相关间隙和角度的检查和调整。主要是火花塞间隙、气门间隙和配气定时等的检查和调整。

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

　　合金尾气发电机组运行一段时间后，火花塞的间隙会有所变大，这是正常现象。若间隙增大到0.89mm时，火花塞将出现失火现象，造成机组运行不稳，甚至停车，所以应定期检查和调整，同时消除火花塞及其螺纹处出现的积炭,确保其好用。

　　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，合金尾气发电机组经长时间运转后，由于配气机构的磨损和松动等原因，会引起气门间隙的变化,应定期检查并调整气门间隙。配气定时在正常情况下不需要进行调整，当机组各缸工作状态出现异常时，应首先检查指针上止点指示位置是否正确，检查传动系统各齿轮传动记号是否对准，整个系统的装配关系及气门间隙是否正确。若经检查调整后，仍与规定值差异较大时，则应考虑凸轮轴或齿轮传动件有无损坏现象，必要时进行修复或更换。

　　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.
