FAW Jiefang truck Weichai engine parts Oil Filter Element 10038880513
Product Introduction
During the operation of the engine, metal grinding chips, dust, carbon deposits oxidized at high temperatures, colloidal sediments, water, etc. are constantly mixed into the lubricating oil. The function of the oil filter is to filter out these mechanical impurities and colloids, keep the lubricating oil clean, and extend its service life. The oil filter should have strong filtering ability, small flow resistance, and long service life. In general, several filters with different filtering abilities are installed in the lubrication system - a collection filter, a coarse filter, and a fine filter, which are connected in parallel or in series in the main oil channel. (The filter connected in series with the main oil channel is called a full-flow filter, and all the lubricating oil is filtered by the filter when the engine is working; the filter connected in parallel with it is called a split-flow filter). Among them, the coarse filter is connected in series in the main oil channel, which is a full-flow type; the fine filter is connected in parallel in the main oil channel, which is a split-flow type.

The function of oil filter
► Oil filter, also known as oil filter. It is used to remove impurities such as dust, metal particles, carbon sediments and soot particles in the oil to protect the engine.
► Oil filters are divided into full-flow and split-flow types. The full-flow filter is connected in series between the oil pump and the main oil channel, so it can filter all the lubricating oil entering the main oil channel. The split-flow filter is connected in parallel with the main oil channel and only filters part of the lubricating oil sent by the oil pump.
Technical features:
● Filter paper: Oil filters have higher requirements for filter paper than air filters, mainly because the temperature of the oil varies from 0 to 300 degrees. Under drastic temperature changes, the concentration of the oil also changes accordingly, which will affect the filtration flow of the oil. The filter paper of a high-quality oil filter must be able to filter impurities under drastic temperature changes while ensuring sufficient flow.
● Rubber seal ring: The filter seal ring of high-quality oil is synthesized with special rubber to ensure 100% oil leakage.
● Backflow suppression valve: Only available in high-quality oil filters. When the engine is turned off, it prevents the oil filter from drying out; when the engine is re-ignited, it immediately generates pressure to supply oil to lubricate the engine. (Also called check valve)
● Overflow valve: Only available in high-quality oil filters. When the external temperature drops to a certain value or when the oil filter exceeds the normal service life, the overflow valve will open under special pressure to allow unfiltered oil to flow directly into the engine. Even so, impurities in the oil will enter the engine, but the damage caused by no oil in the engine is much less. Therefore, the overflow valve is the key to protecting the engine in an emergency. (Also called bypass valve)
