The oil filter element is an oil filter. The function of the oil filter is to remove impurities, gums and moisture from the oil, and to deliver clean oil to each lubricating part.
In order to reduce the friction resistance between the relative moving parts in the engine and reduce the wear of the parts, the oil is continuously transported to the friction surface of each moving part to form a lubricating oil film for lubrication. Motor oil itself contains a certain amount of gum, impurities, moisture and additives. At the same time, during the operation of the engine, the introduction of metal abrasive debris, the introduction of debris in the air, and the generation of oil oxides, gradually increased the debris in the oil. If the engine oil goes directly to the lubricant circuit without being filtered, the debris contained in the engine oil will be brought into the friction surface of the motion pair, which will accelerate the wear of the parts and reduce the service life of the engine.
Because the oil itself has a high viscosity and a high content of impurities in the oil, in order to improve the filtration efficiency, the oil filter generally has three levels, which are the oil collector, the coarse oil filter and the fine oil filter. The filter is installed in the front oil pan of the oil pump, and generally uses a metal strainer. The crude oil filter is installed behind the oil pump and is connected in series with the main oil passage. There are mainly metal scraper type, sawdust filter type, and microporous filter paper type. Microporous filter paper type is now mainly used. The oil fine filter is installed in parallel with the main oil passage after the oil pump. There are two types of microporous filter paper and rotor type. The rotor type oil fine filter uses centrifugal filtration without a filter element, which effectively solves the contradiction between the oil’s permeability and filtration efficiency.
Diesel generator sets usually have four kinds of filters: air filter, diesel filter, oil filter, water filter, diesel filter is introduced below.
Filter: The filter of the diesel generator set is a special pre-filtration equipment for diesel for internal combustion engines. It can filter out more than 90% of mechanical impurities, gums, asphaltenes, etc. in diesel, and can ensure the cleanliness of diesel to the maximum extent. Increase engine life. Unclean diesel will cause abnormal wear of the engine’s fuel injection system and cylinder, which will cause the engine power to decrease, fuel consumption to increase rapidly, and greatly reduce the service life of the generator. The use of diesel filters can greatly improve the filtration accuracy and efficiency of engines using felt diesel filters, extend the life of imported high-quality diesel filters several times, and have significant fuel-saving effects. How to install a diesel filter: The installation of a diesel filter is extremely simple. When using it, you only need to connect it in series to the oil supply line according to the reserved inlet and outlet ports. Pay attention to connect in the direction shown by the arrow. When using and replacing the filter element for the first time, fill the diesel filter with diesel oil and pay attention to exhaust. The exhaust valve is on the end cap of the barrel. How to replace the filter element: Under normal use, if the pressure alarm of the pre-filter device alarms or the accumulated use exceeds 300 hours, the filter element should be replaced. The dual-barrel parallel pre-filter device can be used without stopping the filter element replacement.
