如何维护及保养燃气发电机

来源:http://www.huannengpower.com   发布于:2017-05-26

良好的维护保养能保证机组可靠运行。正常使用情况下,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,确保机组运行在佳状态。在这些保养要求中,注意从以下三个方面的检查和保养:

Good maintenance can guarantee the reliable operation of the unit. In normal use, maintenance shall be carried out in accordance with the required daily maintenance and Zhou Baoyang and monthly maintenance requirements. Through these provisions of the maintenance, can discover whether there is abnormal sound, movement abnormalities, abnormal appearance, abnormal temperature, abnormal pressure and abnormal smell trouble phenomenon and unit, check and adjust timely on the unit, in order to solve, ensure the unit operating in the best state. In these maintenance requirements, pay attention 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,加大维护工作量。

燃气发电机组

1 、 lubrication system inspection and maintenance. The types of units due to the presence of moving parts, moving parts and bad working conditions, mostly in high temperature, high impact load condition, lubrication needs a lot of places, the reliability of the lubrication system requirements are more demanding, therefore, should pay attention to check the lubrication system oil situation, oil level, oil temperature and oil pressure, pay attention to cleaning centrifuge filter and oil filter, avoid bad lubrication unit parts wear caused by the unit, shorten the service life of the parts, increase the workload of maintenance.

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。

2 、 air filter inspection and maintenance. If the air filter is well run, will effectively avoid the pressure due to air resistance caused by the big drop, causing the leakage phenomenon of turbocharger; also can avoid reducing the flow of turbocharger compressor surge phenomenon caused by. Therefore, clean the air filter regularly and replace the filter if necessary. The paper filter can be removed in damp area.

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。

3, relevant clearance and angle inspection and adjustment. Mainly the spark plug gap, valve clearance and timing of gas distribution check and adjust. When the unit is running for a long time, the valve clearance will be changed due to the wear and looseness of the valve mechanism, and the valve clearance shall be regularly checked and adjusted. The timing in normal circumstances do not need to be adjusted, when the working condition of each cylinder unit is abnormal, should first check the pointer indicating the TDC position is correct, check whether the transmission gear mark alignment, assembly and valve clearance of the system is not correct.
