Maintenance method of three types of diesel engine

To extend the service life of the diesel engine, in the process of use, it is necessary to strengthen the maintenance of the three filter cleans of air cleaner, oil filter and fuel filter, and give full play to their role.

Air filter is not allowable, reverse or missed at each sealing gasket and rubber connecting tube when installing, and ensures the rigidity of each embedded. The paper dust cup air filter is used, 50-100 hours, to remove dust, can be brushed away from the surface of the surface with a soft brush, if the working time exceeds 500 hours or is damaged, it should be replaced in time. With an oil-type air filter, each work is 100-200 hours, the cleaned diesel cleaning the filter is applied, and the oil is replaced, if the filter is broken, it will be replaced immediately, and pay attention to the use of oil.

The oil filter is not maintained in time during the use of diesel engine, the filter element is blocked, the oil pressure increases, the safety valve is opened, the lubricating oil flows directly into the main oilway, which will exacerbate the wear of the lubrication surface, affect the life of the diesel engine. Therefore, every 180-200 hours of engine oil filter, it is necessary to wash once, discovering damage, should be replaced immediately to prevent impurities from entering the lubrication surface. The diesel engine is used, and the crankcase and each lubrication surface should be cleaned. The method is to wash the oil after mixing with oil, kerosene and diesel, and can be washed after the oil is released, then the diesel engine is running 3-5 minutes, then put it Add a new oil to the oil.

The various fuel filters in the fuel supply system should be removed once every 100-200 hours, and the debris and the oil tank and various oil pipelines are fully cleaned. When cleaning the filter and seals, it should be special carefully, and it is broken, it needs to be replaced in time. When transitioning in the season, the components of the entire fuel supply system should be cleaned. Diesel uses should meet the seasonal requirements and require 48 hours of precipitation purification treatment.
