Abstract

The invention relates to a filter method using wave suppression, magnetization, adsorption and rotating magnetic field, which attenuates the pressure / flow pulsation of hydraulic oil through the filter, and adopts the working condition self-adaptive wave suppression filter; realizes it through the U-shaped particle separation module The separation of solid particles makes the solid particles in the oil move to the pipe wall, and enter the oil return cylinder through the oil return tube inlet pipe and then return to the oil tank. It enters the inner cylinder for high-precision filtration, which improves the service life of the filter element; the oil entering the oil inlet pipe of the inner cylinder flows into the spiral flow channel of the inner cylinder in a tangential flow, and the inner cylinder wall is the filter element, and the filtrate is under the action of centrifugal force It flows close to the filter element, the filtrate flows quickly parallel to the surface of the filter element, and the filtered hydraulic oil flows out to the outer cylinder perpendicular to the surface of the filter element; the pollution particles deposited on the bottom of the inner cylinder can be discharged to the return oil through the electronically controlled check valve at regular intervals cartridge, thereby increasing the service life of the filter element.

Description

Technical field

[0001] The invention relates to a hydraulic oil filtering method, in particular to a filtering method using wave suppression, magnetization, adsorption and rotating magnetic field, and belongs to the technical field of hydraulic equipment.

Background technique

[0002] Statistics at home and abroad show that about 70% to 85% of hydraulic system failures are caused by oil pollution. Solid particles are the most common and harmful pollutants in oil pollution. Hydraulic system failures caused by solid particle pollutants account for 70% of total pollution failures. Metal debris accounts for 20% to 70% of the particle pollutants in hydraulic system oil. Taking effective measures to filter out the solid particle pollutants in the oil is the key to the pollution control of the hydraulic system, and it is also a reliable guarantee for the safe operation of the system.
