Targeted filtration device for composite filtration

Abstract

The invention discloses a targeted filtration device for composite filtration. A coarse filter screen is arranged on the surface of a cylinder body, a first cover plate and a second cover plate are respectively arranged at the upper end and the lower end of the cylinder body, an outlet pipe seat is arranged at the lower end of the second cover plate, and a built-in filter element is arranged in the cylinder body above the outlet pipe seat; and a plurality of magnetic bar units are arranged in the barrel body at intervals in the axial direction of the barrel body, the magnetic bar units are fixed through a chuck arranged in the barrel body, the flow field range controlled by each magnetic bar unit is 0-30 mm, and the total through-flow area of the barrel body is larger than 3-4 times of the through-flow area of a pipeline. The filtration device for composite filtration has obvious use effect and strong application adaptability, can achieve the purpose of targeted filtration, and does not cause harm to oil liquid due to type selection of filter materials.

Description

technical field [0001] The invention belongs to the technical field of oil cleaning, and in particular relates to a targeted filtering device for compound filtering. Background technique [0002] The lubricating oil system needs to maintain clean oil quality. Various complex wear and impacts will inevitably occur when the machine is running, and the metal abrasive particles will fall off and increase gradually. This metal particle is a very harmful substance, and there will be a large amount of metal in the oil system. Particles, the particle size of these particles is very small, there will be more than one million micron-sized metal particles in 100 ml of oil, which will cause excessive wear of rotating parts, and metal particles will cause accelerated oxidation of lubricating oil, eventually Lead to premature oil failure and scrap. [0003] The vast majority of traditional filter devices use filter elements made of fiber material and metal keels. This filter element is c...
