What is lubricating oil filtration? What is the function and principle of lubricating oil filter? With the continuous development of automobile technology, many new products have also emerged, and lubricating oil filter is one of them.

Introduction to lubricating oil filtration

As lubricating oil may contain some mechanical particles or debris during production and use, if it is not cleaned for a long time, it may cause damage to the internal parts of the engine. Therefore, a lubricating oil filter can be installed in the car to maintain a certain pressure difference at both ends of the filtration, so as to intercept those solid particles or impurities, thereby protecting the engine. It also has multiple filtering methods such as gravity filtration, vacuum filtration, pressurized filtration and centrifugal filtration.

Function and principle of lubricating oil filter

Function: 

For the engine, since the lubrication of various parts during use will bring some metal grinding chips, dust, carbon deposits oxidized at high temperature, colloidal sediments, water, etc. into the lubricating oil, which will shorten the service life of the lubricating oil. Therefore, the main function of the lubricating oil filter is to filter out these mechanical impurities and colloids, keep the lubricating oil clean, extend its service life, and protect the internal parts of the engine. It also has strong filtering ability, small flow resistance, and long service life. However, it can only filter some impurities in the lubricating oil, and cannot be completely filtered. After a long time of use, there is no filtering effect.

Principle: 

The working principle of the lubricating oil filter is to filter through pressure difference, that is, to install a filter inside the car, the lubricating oil can pass through, and those fixed impurities or some water will be intercepted, thereby achieving the filtering effect.
