The correct operation of 4 stroke diesel engine generator set can not only prolong the service life, but also improve the working efficiency quickly and effectively, and ultimately bring the maximum benefits to users. Therefore, the user should operate the equipment correctly in the process of using the diesel generator, and change some bad operating habits. The following content describes four wrong operation methods.
Wrong Operation A
When the engine oil of 4 stroke water cooled diesel engine generator set is insufficient, the oil supply on the surface of each friction pair will be insufficient due to the insufficient oil supply, and finally due to abnormal wear or burn. Therefore, before starting the unit, it is necessary to check whether the engine oil is sufficient, and prevent the cylinder pulling and tile burning failure caused by the lack of oil.
Wrong Operation B
The electric start 4 stroke diesel engine generator set stops in case of load or immediately after the load is removed. The circulation of cooling water in the diesel generator will stop after the diesel generator stops, resulting in a sharp decrease in the heat dissipation capacity of the machine. At this time, the heated parts lose cooling, which is easy to cause overheating of cylinder head, cylinder sleeve, cylinder block and other parts, resulting in cracks, or excessive expansion of the piston stuck in the cylinder liner. On the other hand, if the diesel generator is stopped without idling, the lubricating oil on the friction surface will be insufficient. When the diesel engine is started again, the wear will be intensified due to poor lubrication. Therefore, the diesel generator should be unloaded before flameout, and gradually reduce the speed, no-load operation for several minutes.
Wrong Operation C
The high speed 6 cylinder diesel engine generator runs with load without warming up after cold start. During the cold start of diesel generator, because of the high viscosity and poor fluidity of the oil, the oil supply of the oil pump is insufficient, and the friction surface of the machine is badly lubricated due to the lack of oil, resulting in sharp wear, even cylinder pulling, tile burning and other faults. Therefore, the diesel generator should be idling after cold start, and gradually warming up in this process, and then running with load when the oil temperature reaches 40℃ or above.
Wrong Operation D
The KPV1100 diesel engine generator set operates under the condition of insufficient cooling water or high temperature of cooling water and oil. The insufficient cooling water of diesel generator will reduce its cooling effect, and the diesel generator will overheat due to the lack of effective cooling. If the temperature of cooling water and oil is too high, the diesel engine will overheat. At this time, the main parts of the diesel generator, such as cylinder head, cylinder sleeve, piston assembly and valve, are too seriously heated, and their mechanical properties, such as strength and toughness, are sharply reduced, which makes the parts deformed, reduces the fitting clearance between parts, and accelerates the wear of parts.
