Filtering device adopting wave suppression, electrification, separation and adsorption

Abstract

The invention relates to a filtering device adopting wave suppression, electrification, separation and adsorption. A filter, a U-shaped particle separating module, an oil return barrel and an outer barrel of the filtering device are sequentially mounted on a bottom plate. The filter is connected with the U-shaped particle separating module, and the working-condition self-adaptive wave suppression filter is adopted. The U-shaped particle separating module comprises a U-shaped pipe which is sequentially provided with an electrification module, a separation module, adsorption modules and a demagnetization module. The upper portion of the U-shaped particle separating module and the upper portion of the oil return barrel are connected through an oil return barrel oil inlet pipe. An inner barrel is arranged in the outer barrel and mounted on an end cover through a top plate and a plurality of bolts. A spiral flow channel is accommodated in the inner barrel and connected with the U-shaped particle separating module through an inner barrel oil inlet pipe. The inner barrel oil inlet pipe is located in the oil return barrel oil inlet pipe and extends into the center of the U-shaped particle separating module, and a filter element is arranged on the inner wall of the inner barrel. The filtering device has the advantages of being good in filtering performance, high in adaptability and integration, long in service life and the like.

Description

【Technical Field】 [0001] The invention relates to a hydraulic oil filter, in particular to a filter device adopting wave suppression, electrification, separation and adsorption, and belongs to the technical field of hydraulic equipment. 【Background technique】 [0002] Statistics at home and abroad show that about 70%-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 particulate pollution accounted for 70% of total pollution failures. Among the particulate pollutants in the hydraulic system oil, metal wear debris accounts for 20% to 70%. Taking effective measures to filter out solid particle pollutants in the oil is the key to the pollution control of the hydraulic system and a reliable guarantee for the safe operation of the system. [0003] The filter is a key element of the hydraulic system to filter out solid particulate pollutants. The solid par...

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 problems of cost and installation complexity; (2) The filter in the hydraulic system mainly adopts the filter cake filter method, and the filtrate is perpendicular to the The surface of the filter element flows, and the intercepted solid particles form a filter cake and gradually thicken, and the filtration speed gradually decreases until the filtrate stops flowing out, which reduces the service life of the filter element
