(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;
(1) inspection and maintenance of lubrication system. 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) inspection and maintenance of air filters. If the air filter works well, it will effectively avoid the excessive pressure drop caused by the large intake resistance, which will result in the oil leakage phenomenon of the turbocharger, and also avoid the compressor surge phenomenon caused by the flow reduction. Therefore, the air filter should be cleaned regularly, and new filter elements should be replaced if necessary. The paper filter element can be removed in humid 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。
(3) inspection and adjustment of relative clearance and angle. The inspection and adjustment of spark plug clearance, valve clearance and timing of gas distribution are mainly.
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。以泰州市兆航机电设备有限公司生产的设备为例当间隙增大到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 for a period of time, the gap of the spark plug will become larger, which is a normal phenomenon. Produced by Taizhou zhaohang Electrical Equipment Co., Ltd. equipment as an example when the gap increased to 0. 89mm, the spark plug will appear on fire phenomenon caused by running instability, or even stop, so should be regularly checked and adjusted at the same time, eliminating coke spark plug and screw, ensure its good use.
另外,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 the unit running for a long time, due to the wear and loose valve mechanism and other reasons, will cause changes in valve clearance, should regularly check and adjust valve clearance. 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. If the check adjustment, still with the specified values differences, should be the camshaft or gear transmission parts have no damage, repair or replacement when necessary.
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,确保机组运行在最佳状态。
Good maintenance can ensure the reliable operation of the unit. Under normal use, maintenance work should be carried out according to the required daily maintenance, 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.
