Causes of oil consumption too fast in diesel generator set
2021-07-17
Serious wear of diesel engine compression system, wrong piston assembly, damage of sealing gasket at each joint of engine block and damage of oil shell side wall are the causes of excessive oil consumption（ For reference only: (Guangxi laines diesel generator set ☏: 1387710122 answers for you)
1、 When excessive oil consumption is found, check whether there is oil leakage at the connection between the engine body and the gear chamber cover, the large plate on one side of the wheel, the rear cover and the cover. In case of oil leakage, pay attention to observe whether the sealing gasket of each connection part is complete, and replace the damaged sealing gasket. If the gasket is complete, check whether the connecting screws of each part are loose. For loose bolts, use a wrench to reach the specified torque. If the above parts are basically normal, and the oil leakage is at the frame position, the oil case should be inspected. The main inspection part is at the front end of the oil case side on the same side as the running wheel. Because the frame screw is loose, the running wheel has a long-term collision with the frame angle iron to protect the oil case under the pull of the V-belt, and the oil case is worn through to form a gap, resulting in oil leakage.
2、 The normal wear caused by long-term use of the engine or abnormal wear caused by improper maintenance will make the cylinder liner of the diesel engine form longitudinal stretch marks, and the cylinder diameter and piston side clearance exceed the specified value, which will reduce the supporting force of the piston ring and cause the phenomenon of unclean oil scraping. Or because the inner support twisted spring in the oil ring is disconnected at the opening position of the oil ring, the oil scraping is not clean and participates in the combustion, resulting in the symptoms of serious oil consumption, such as difficulty in starting the diesel engine, obvious blue smoke emission from the exhaust pipe, and serious oil injection from the respirator. Moreover, when the piston should be upward, the combustion chamber will be inverted due to the inverted direction during assembly. Although it will not affect the starting of the diesel engine, the oil loss will be quite serious, and the oil consumption is about 0.5kg per day.
3、 Although it is rare that the engine oil of diesel generator set will be burned even if the valve guide is seriously worn, according to the introduction of relevant information, it is also a reason that can not be ignored.
