The utility model discloses a supercharging oil cylinder. The supercharging oil cylinder comprises a cylinder body (10) and a separation member (20), wherein the separation member (20) is arranged in the cylinder body (10) so as to divide a cavity of the cylinder body (10) into a first cavity (30) and a second cavity (40), a piston (50) is arranged in the first cavity (30), the first cavity (30) is divided by the piston (50) into a rodless cavity (301) and a rod cavity (302), a piston rod (6) runs through the separation member (20) so as to enter the second cavity (40), and the super charging oil cylinder also comprises a first oil port (A), a second oil port (B), a third oil port (C) and a fourth oil port (D). The utility model discloses a supercharging system and a sealing performance experiment table comprising the supercharging oil cylinder. By adopting the supercharging oil cylinder, not only can the high-pressure hydraulic oil be outputted, but also the hydraulic oil with the pressure being approximately zero can be outputted.
