Oil filter adopting full-frequency-band working-condition self-adaption smoothing, electrification and rotational magnetic field

Abstract

The present invention relates to an oil filter with self-adaptive filtering, electrification and rotating magnetic field under full-frequency working conditions. The filter, U-shaped particle separation module, oil return cylinder and outer barrel are sequentially placed on the bottom plate; the filter and U The U-shaped particle separation module is connected with a full-band working condition adaptive filter; the U-shaped particle separation module includes a U-shaped tube, and the U-shaped tube is sequentially installed with an electrification module, a separation module, a first adsorption module, and a rotating magnetic field centrifuge. module, the second adsorption module and degaussing module; the U-shaped particle separation module and the upper part of the oil return cylinder are connected through the oil return pipe of the oil return cylinder; the inner cylinder is placed in the outer barrel, which is installed on the end cover; the spiral flow channel is contained in the Inside the cylinder, it is connected with the U-shaped particle separation module through the oil inlet pipe of the inner cylinder; the oil inlet pipe of the inner cylinder is located in the oil inlet pipe of the oil return cylinder; the filter element is arranged on the inner wall of the inner cylinder. The invention has many advantages such as good filtering performance, high adaptability and integration, long service life and the like.

Description

【Technical field】 [0001] The invention relates to a hydraulic oil filter, in particular to an oil filter using self-adaptive filtering, electrification and rotating magnetic field in full frequency band working conditions, 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. [0003] Filters are key components of hydraulic systems to remove s...

Problems solved by technology

[0004] However, the high-pressure filter used in the existing hydraulic system has the following deficiencies: (1) various hydraulic components have different requirements for the cleanliness of the oil, and the particle sizes of the solid particles in the oil are also different. This requires the installation of many different types of filters at different positions in the hydraulic system, which brings about probl
