(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) 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) 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.
。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.
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.
