Problems solved by technology

At present, domestic engine hydraulic systems mostly use active interception oil filters, which use surface or depth filter media to remove solid particles in fuel, but due to certain limitations in the filter mechanism, pollutants are easy to deposit on the surface and inside of the filter material, causing blockage. filter element, resulting in increased flow resistance, resulting in poor filter dirt holding capacity and short maintenance intervals

Abstract

The invention belongs to the technical field of contamination control of an aviation turbine fuel system, and particularly relates to a combined filter. The combined filter comprises a self-washing oil filtering framework, wherein an oil return opening of the self-washing oil filtering framework is connected with a self-washing oil filtering oil return pipe; an inlet end of the self-washing oil filtering framework is fixedly connected with a turbulence promoter; an inlet end of the turbulence promoter is connected with a self-washing oil filtering inlet pipe; the self-washing oil filtering framework is provided with a self-washing oil filtering screen; a self-washing oil filtering oil outlet connected with a turbulence oil filtering inlet pipe is formed in the turbulence promoter in a position corresponding to the self-washing oil filtering screen. The combined filter is simple and reasonable in structure, can effectively solve the problems of poor assimilative capacity and short maintenance cycle of an existing combed filter in the operation process, can greatly reduce the pollutant deposition on the surface of a filter material, and effectively prolong the maintenance cycle of the combined filter.

Description

technical field [0001] The invention belongs to the technical field of pollution control of aviation turbine engine fuel system, in particular to a combined filter. Background technique [0002] Oil contamination is the main cause of hydraulic system failure in aeroengines. With the use of high-precision and high-response components, hydraulic systems have increasingly high requirements for oil cleanliness. At present, domestic engine hydraulic systems mostly use active interception oil filters, which use surface or depth filter media to remove solid particles in fuel, but due to certain limitations in the filter mechanism, pollutants are easy to deposit on the surface and inside of the filter material, causing blockage. filter element, resulting in increased flow resistance, resulting in poor filter dirt holding capacity and short maintenance intervals. [0003] 3D printing technology, a type of rapid prototyping technology, is based on digital model files, using powdered...
