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 、 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 、 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, 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.
