Description

Bypass filter for lubricating oil

Technical Field

The utility model relates to a bypass filter technical field specifically is a bypass filter for lubricating oil.

Background

The utility model relates to a bypass filter technique, the principle is that the filter core is in the continuous circulation of circulation in-process and adsorbs, and the long fiber of filter core absorbs the water that generates after the fuel burning and the water that the condensation produced like the sponge, repels big oil molecule simultaneously, and these oil molecules will pass through the filter core under pressure. As the oil passes through the filter element, tiny particles of carbon and silicon molecules adhere to the filter element, a process known as adsorption. The filter element absorbs water to prevent water from generating acid which can degrade oil and accelerate abrasion. Meanwhile, the oil can adsorb tiny pollution particles, so that the oil is cleaner, the function of the oil is fully exerted, and the service life of the oil is prolonged.
