Carry out daily maintenance for gas generator in strict accordance with the requirements to ensure reliable operation of the unit. Good maintenance can ensure the reliable operation of the unit. Under normal use, the maintenance should be carried out according to the requirements of daily maintenance, weekly maintenance and monthly maintenance.

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,确保瓦斯发电机运行在好状态。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:

Through the maintenance of these regulations, we can timely find out whether there are abnormal sound, abnormal action, abnormal appearance, abnormal temperature, abnormal pressure, abnormal smell and other fault phenomena in the unit, so as to timely check and adjust the unit, and then solve them pertinently, so as to ensure that the gas generator runs in a good state. In 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。该种类型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,避免出现因润滑不好造成的机组零部件磨损加剧,缩短机组零部件的使用寿命,加大维护工作量。

(1) Inspection and maintenance of lubrication system. This type of unit has many operating components, and the operating conditions of the operating components are harsh. Most of the operating components are under high temperature and high impact load. There are many parts that need to be lubricated, and the reliability of the lubrication system is more demanding. Therefore, it is necessary to pay attention to check the oil quality, oil level, oil temperature and oil pressure of the lubricating oil system, and pay attention to the cleaning of centrifugal filter and oil filter, To avoid the aggravation of the wear of the unit parts caused by poor lubrication, shorten the service life of the unit parts and increase the maintenance workload.

(2)空气过滤器的检查和保养。空气过滤器如果运转良好的话,将有用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。

(2) Inspection and maintenance of air filter. If the air filter works well, it will effectively avoid the excessive pressure drop caused by the large intake resistance, which will cause the oil leakage of the turbocharger; It can also avoid the surge phenomenon of turbocharger compressor caused by flow reduction. Therefore, clean the air filter regularly and replace the filter element if necessary.

(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。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。

(3) Check and adjust the clearance and angle. It mainly includes the inspection and adjustment of spark plug clearance, valve clearance and valve timing. After the unit has been running for a period of time, the gap of spark plug will become larger, which is a normal phenomenon.

瓦斯发电机经长时间运转后,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。

Gas generator after a long time of operation, due to the valve train wear and loose and other reasons, will cause changes in valve clearance, should be regularly checked and adjusted valve clearance. It is not necessary to adjust the valve timing under normal conditions. When the working state of each cylinder of the unit is abnormal, it is necessary to first check whether the indication position of the top dead center of the pointer is correct, whether the gear transmission marks of the transmission system are aligned, and whether the assembly relationship and valve clearance of the whole system are correct. If there is still a big difference between the value and the specified value after inspection and adjustment, the camshaft or gear transmission parts shall be considered for damage and repaired or replaced if necessary.
