What is an oil filter
The oil filter is the machine filter we often say. Its function is to remove impurities such as dust, metal particles, carbon deposits and soot particles in the oil to protect the engine.we are oil filter wholesale and best oil filter china,you can know it.
During the operation of the engine, metal grinding debris, dust, oxidized carbon deposits and colloidal deposits at high temperatures, water, etc. are constantly mixed into the lubricating oil. The function of the oil filter is to
filter out these mechanical impurities and gels, to keep the lubricant clean and to extend its service life. The oil filter should have strong filtration capacity, low flow resistance and long service life.
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 stages, namely the oil filter, the oil strainer and the oil
fine filter. The filter is installed in the oil pan of the oil pump, and is generally made of metal mesh. The oil coarse 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. Now, the microporous filter paper type is mainly used. The fine oil filter is installed in parallel with the main oil passage after the oil pump, and mainly
has two types of microporous filter paper and rotor type. The rotor type oil filter adopts centrifugal filtration and has no filter element, which effectively solves the contradiction between the oil passage and the filtration
The oil filter, also known as the machine filter, is located in the engine lubrication system. The upstream of the filter is the oil pump, and the downstream is the parts of the engine that need lubrication.
The machine filter filters harmful impurities from the oil from the oil pan, and supplies the motor oil to the crankshaft, connecting rod, camshaft, supercharger, piston ring and other motion pairs to lubricate, cool and clean. The
life of these components.
The function of the machine filter is to filter out the harmful impurities in the oil from the oil pan, and supply the motor oil to the crankshaft, connecting rod, camshaft, supercharger, piston ring and other sports pairs to play the
role of lubrication, cooling and cleaning. To extend the life of these components.
Machine filter structure
The machine filter is divided into a removable type, a spin-on type, and a centrifugal type according to the structure; the arrangement in the system can be divided into a full-flow type and a split-flow type. Filter materials used
for machine filtration include filter paper, felt, metal mesh, nonwoven fabric, and the like.
Machine filter development history
Before the 1980s, most of the domestic engines used were replaceable filters. The filter of this structure is to put the filter element and other parts, such as a spring, a sealing ring and the like into a metal casing, and connect
the casing filter element and the like to a metal filter seat through a tie rod. The advantage of the replaceable filter is that the use cost is low, and only need to be regularly maintained and replaced with the filter element; the
disadvantage is that there are too many sealing points, the maintenance and replacement of the filter element may leak parts, which is easy to cause loopholes, and the replacement is troublesome. Since the early 1980s, spin-on filters
have gradually been approved for domestic OEMs. The spin-on filter is characterized by a check valve, a bypass valve and a sealing point inside, which are replaced as a whole, which greatly improves the sealing performance and is easy
to replace. The filter material is mostly imported filter paper, so the filtration efficiency is high. The flow resistance is small and the life is long.
