The utility model discloses a dynamic oil filtering system of a land bridge hydraulic pump station, which aims at providing a system capable of prolonging the service life of oils, reducing the fault rate of a hydraulic system, prolonging the using period of hydraulic oil, and reducing the costs of production and operation. An oil inlet of a system pump is connected with an oil outlet of the hydraulic pump station; an oil outlet of the system pump is connected with an inlet of a filter chamber; an outlet of the filter chamber is connected with an auxiliary oil returning port of the hydraulic pump station; a pressure gage is connected on the filter chamber; and a filter element is arranged in the filter chamber. The hydraulic oil of the hydraulic oil pump station is filtered by the dynamic oil filtering system of the land bridge hydraulic pump station on line, moisture, gas, harmful impurities and the like in the hydraulic oil are removed, and then the hydraulic oil is pressed back into the hydraulic pump stat
