Hydraulic oil filtering system

Abstract

The utility model relates to the field of hydraulic equipment, in particular to a hydraulic oil filtering system which comprises a rack, a filtering assembly and a recycling assembly, the filter assembly comprises a filter barrel, a first liquid inlet pipe and a first liquid outlet pipe which are connected with the filter barrel, and a pump body acting on the first liquid inlet pipe; the recovery assembly comprises a box body, a second liquid inlet pipe and a second liquid outlet pipe which are communicated with the box body, and a vacuum pump connected with the box body; an inlet of the first liquid inlet pipe and an inlet of the second liquid inlet pipe are communicated with an outlet of a hydraulic oil tank, and an outlet of the first liquid outlet pipe is communicated with an inlet of the hydraulic oil tank; the liquid inlet end of the pump body is connected with a filter used for intercepting particulate matter with the particle size larger than or equal to a threshold value in fluid. The liquid outlet end of the pump body is connected with a pressure sensor and a pressure release valve. The filtering assembly and the recycling assembly are integrally arranged, so that the occupied space of a site is reduced.
