LUBRICATING OIL FILTER FUNCTION AND PRINCIPLE

Improved high performance engines and new emission standards have a significant impact on the development of lubricants and lubricating oil filters. With manufacturers continuously developing more advanced engines, new classification standards for lubricants are also continuously being developed.Clean lubricating oil is essential for engine performanceThese new lubricants, which reduce friction and wear, cool engine parts, seal the combustion chamber, clean engine components, and inhibit corrosion, play a vital role in protecting internal combustion engines. Lubricating oil filters, which remove harmful contaminants from the lubricating oil, also play an important role in protecting engines.

THE OIL FILTER CAPTURES IMPURITIES IN THE OIL IN TWO WAYS.

As the lubricating oil flows through the filter, some particles adhere to the filter paper. These particles themselves attach to the surface of the filter paper do not block the pores of the filter paper.

Other particles are collected in the filter paper due to the pressure of the lubricating oil as it passes through the filter.

Oil Inlet Filter Bag

Features of the oil inlet filter bag: The internal space of the filter is used more fully, eliminating the space waste that exists in traditional sidein types. Opening the top cover allows for quick and easy replacement of the filter bag, unlike traditional side-in types where you need to remove the filter bag and press the ring to replace it, reducing the risk of secondary contamination. The liquid inlet pipe is wide and smooth, and the inside of the top cover is bell-shaped, allowing the liquid to distribute pressure after entering, reducing the impact on the filter bag and making the filtration faster and more stable. When the liquid enters the side-in filter, it will produce turbulent flow, resulting in a large pressure loss, and it may also cause the filter bag to turn over inside the filter, leading to unexpected rupture of the filter bag. The bag uses a patented ring mouth, which is closely attached to the filter machine and will not loosen, and multiple seals provide better sealing effects.

The quality of hydraulic oil has a significant impact on the operational performance of hydraulic systems, and many faults originate from it. Installing oil filters in appropriate locations can trap contaminants in the oil, keeping it clean and ensuring the normal operation of the oil system.Hydraulic oil filters be divided into surface type, depth type, and magnetic filters based on the filtering material. Their filtration of solid contaminants is achieved through direct interception and adsorption. main function of hydraulic oil filters is to filter hydraulic oil. Various impurities inevitably appear in hydraulic systems. The main sources include: mechanical impurities that remain in the hydraulic system after cleaning, as rust, casting sand, welding slag, iron chips, paint, paint chips, and cotton thread scraps; impurities that enter the hydraulic system from the outside, such as dust enters through the refueling port and dust ring; and impurities generated during the operation process, such as fragments formed by seals under hydraulic action, metal powder generated by relative wear movement, and colloidal, asphaltic, and carbonaceous substances generated by oil deterioration due to oxidation. When these impurities mix with hydraulic oil, they will actructively everywhere as the hydraulic oil circulates, seriously affecting the normal operation of hydraulic systems. For example, they can cause small clearance (in the order of magnitude) between relatively parts in hydraulic components, as well as small holes and gaps in throttle valves to become stuck or blocked; they can destroy the oil film between relatively moving parts, scratch the surface of, increase internal leakage, reduce efficiency, increase heat generation, and intensify the chemical action of the oil, causing the oil to deteriorate. According to production statistics, more than75% of faults in hydraulic systems are caused by impurities mixed in hydraulic oil. Therefore, maintaining the cleanliness of the oil and preventing the pollution of the oil are very important hydraulic systems.
