The "three filters" of diesel generator sets include oil filters, air filters and fuel filters; "two oils" refer to fuel and lubricating oil. When maintaining a diesel generator set, the replacement of these filters and oils is very important. They can effectively prevent impurities from entering the engine and improve the service life and performance of the engine.
(i) The function of the oil filter is to filter particulate matter and pollutants in the oil and keep the oil clean. During maintenance, the old oil filter needs to be removed and replaced with a new one. During the replacement process, it is necessary to first apply a layer of oil to the sealing ring of the oil filter and then tighten it to the specified torque.
(ii) The function of the air filter is to filter dust and particulate matter in the air and protect the engine from pollution. When replacing the air filter, you need to open the filter cover first and remove the old air filter. Before installing the new air filter, you need to clean the filter cover and apply a layer of lubricating oil. Then install the new air filter in place and tighten the cover.
(III) The function of the fuel filter is to filter impurities and moisture in the fuel to prevent damage to the fuel system. When replacing the fuel filter, you need to turn off the fuel supply switch and then remove the old fuel filter. Before installing the new fuel filter, you need to apply a new seal and tighten it to the specified torque.
(IV) The replacement of lubricating oil requires the old lubricating oil to be discharged and replenished with new lubricating oil. When replacing the lubricating oil, you need to pay attention to selecting the appropriate lubricating oil brand and ensure that the quality of the lubricating oil meets the requirements.
(V) The replacement of fuel also requires the old fuel to be discharged and replenished with new fuel. When replacing the fuel, you need to pay attention to selecting the fuel brand that meets the requirements and ensure that the quality of the fuel is good.
When the diesel generator set is overhauled, the "three filters and two oils" must be replaced according to a certain period. The specific replacement time can be consulted by the manufacturer. Reasonable maintenance and care can extend the service life of the generator set, ensure the normal operation of the generator set, and improve its reliability and safety.
