Briefly describe the structure and maintenance of the diesel generator set air filter

The function of the diesel generator set air filter is to filter out the dust and impurities in the air entering the diesel generator set, so as to ensure the clean air in the cylinder and reduce the damage between the cylinder and the piston, the piston set itself, and the valve set parts. Wear and prolong the service life of diesel generator sets.

air filter

 

       Diesel generator set is a kind of mechanical equipment that uses diesel as the main fuel and converts kinetic energy into electrical energy and thermal energy by burning diesel. The power of diesel generator sets comes from the heat energy generated by combustion, and the prerequisite for combustion is sufficient and clean air, so the air filter is particularly important. The structure and maintenance of the cleaner.

 

       The role of the air filter

       The function of the diesel generator set air filter is to filter out the dust and impurities in the air entering the diesel generator set, so as to ensure the clean air in the cylinder and reduce the damage between the cylinder and the piston, the piston set itself, and the valve set parts. Wear and prolong the service life of diesel generator sets.

 

       Classification structure and maintenance of air filter

       The air filter is divided into a dry air filter and a wet air filter. The dry air filter does not need to be filled with oil to filter out impurities in the air. The principle is to change the air flow direction or make The air passes through the filter element with micropores to achieve the purpose of purifying the air. The filter element of dry air filter generally has two kinds of metal mesh filter element and paper filter element. Generally, after 150 hours of use, these two filter elements need to be cleaned of impurities. After the metal mesh filter element is taken out, it should be cleaned in gasoline and dried with compressed air. After the paper filter element is taken out, the end face of the filter element is generally tapped lightly with a hand or a wooden stick to make the dust and impurities adsorbed on the filter element fall off.

 

       According to certain technical requirements, organic oil is placed at the bottom of the wet filter housing, the purpose of which is to use the viscosity of the oil to absorb the dust and impurities entering the air in the cylinder. When there is a lot of dust and impurities adsorbed by the wet air filter element, the filter element can generally be placed in gasoline for cleaning and dried with compressed air. After changing the oil, put the dried filter element into the air filter housing. At present, the wet air filter is more commonly used in diesel engines.
