This utility model discloses a hydraulic oil iron filings filtration device for a piston-feeding centrifuge. Its features include a guide plate and chip baffle mounted on a side rib, an iron filings bubble filter frame mounted on the side rib and above the guide plate and chip baffle, a filter screen on the iron filings bubble filter frame to eliminate air bubbles as the hydraulic oil passes through, and several magnetic strips on the iron filings bubble filter frame for filtering iron filings. Through the guide plate and magnetic strips, when iron filings travel with the hydraulic oil from the return oil zone through the oil cooling zone, the guide plate and chip baffle prevent the hydraulic oil from reaching the suction zone only through the iron filings bubble filter frame. As the hydraulic oil passes through the iron filings bubble filter frame, the iron filings are attracted by the magnetic strips on the frame, thus filtering the iron filings in the hydraulic oil. This prevents iron filings from re-entering the pressure cylinder with the hydraulic oil, which would aggravate wear on moving parts, leading to abnormal noise or complete damage to the piston assembly.
