The large accumulation of carbon will affect the service life of diesel generator sets, how often to clean the carbon?
July 12, 2022
When a diesel generator set fails, it is often caused by a small problem that accumulates slowly, such as a long time without cleaning carbon, the largest accumulation of carbon will often contaminate the lubrication system, block the oil circuit and filter, which affects the normal operation of the diesel generator set, resulting in the life of the diesel generator set is greatly reduced.
When the diesel generator sets fail, it is often caused by a small problem slowly accumulate, such as a long time not to clean carbon, the most accumulation of carbon will often pollute the lubrication system, blocking the oil circuit and filter, and then affect the normal operation of the diesel generator set, resulting in the service life of the diesel generator set is greatly reduced.
Generally diesel generator in use for a period of time, cylinder head, cylinder liner, piston, piston ring, combustion chamber, injector and other parts of the surface will adhere to a solid layer of carbon, which is a complex mixture of diesel and oil penetration into the cylinder incomplete combustion, it is dense, loose, soft, poor thermal conductivity, if the surface of the parts of a large amount of carbon accumulation, will lead to diesel generator set parts local If a large amount of carbon accumulates on the surface of the parts, it will lead to localized overheating of the diesel generator set parts, making its stiffness and strength drop, and in serious cases, it will also cause sintering of the injector nozzle, valve ablation, piston ring seizure, cylinder pulling and other serious accidents, which seriously affects the efficient operation of the diesel generator set.
The reasons for the accumulation of carbon in diesel generators are
n poor quality of diesel fuel, containing impurities.
n The lubricating oil in the diesel generator is used for too long, and the gel contains high.
n loose piston ring, too large, the gap between the valve guide and valve stem is too large, resulting in oil fleeing into the combustion chamber combustion.
n ignition timing too early or too late, the injection pump oil supply is too large.
n diesel generator long time low temperature operation or cylinder seals wear, damage, so that the fuel combustion is not complete.
n Injector pressure is too low, poor atomization, dripping and leakage.
n Diesel generator overload operation for a long time.
At present, the commonly used methods to remove carbon are mainly mechanical method, nuclear spray method, chemical method and electrolysis method, in the process of cleaning carbon, according to the formation of carbon causes, parts and their own conditions after comprehensive consideration to choose a specific solution. We must regularly clean up the carbon, do not wait until the carbon reaches a certain level and then clean up, which will not only greatly reduce the benefits of diesel generators, but also increase the difficulty of cleaning.
