Classification of oil filter

Due to the high viscosity of the oil itself and the high content of impurities in the oil, in order to improve the filtration efficiency, the oil filter generally has three levels, namely the oil collector, the coarse oil filter and the fine oil filter. The filter collector is installed in the front oil sump of the oil pump, and generally adopts a metal filter screen type. The coarse oil filter is installed behind the oil pump and connected in series with the main oil passage. There are mainly metal scraper type, sawdust filter type, and microporous filter paper type. Now the microporous filter paper type is mainly used. The fine oil filter is installed behind the oil pump and connected in parallel with the main oil passage. There are mainly two types: microporous filter paper type and rotor type. The rotor-type oil fine filter adopts centrifugal filtration and has no filter element, which effectively solves the contradiction between oil passability and filtration efficiency.

The function of the oil filter:

The filter of the diesel generator set is a special pre-filtering equipment for diesel oil for internal combustion engines. It can filter out more than 90% of the mechanical impurities, gums, asphaltenes, etc. in the diesel, and can guarantee the diesel to the greatest extent. The cleanliness improves the service life of the engine. Unclean diesel will cause abnormal wear and tear of the engine’s fuel injection system and cylinders, reduce engine power, rapidly increase fuel consumption, and greatly reduce the service life of the generator. The use of diesel filters can greatly improve the filtering accuracy and efficiency of engines using felt-type diesel filters, extend the life of imported high-quality diesel filters several times, and have obvious fuel-saving effects.
