Abstract: This disclosure discloses a water-lubricated high-pressure pump using rolling support, including a driving mechanism, a shell, a rolling bearing, an isolation structure, at least one plunger and a plunger chamber. The driving mechanism includes a main shaft and at least one eccentric structure, and the main shaft is rotationally connected to the shell through the rolling bearing. The eccentric structure is located in a first inner chamber of the shell, which is configured for filling water or aqueous solution. The rolling bearing is located in a second inner chamber of the shell, and the isolation structure is configured to seal the water or aqueous solution inside the shell to prevent the water or aqueous solution from entering into the second inner chamber. When the eccentric structure is rotated, the eccentric structure can push the plunger to move in the plunger chamber to realize pressurization of the water or aqueous solution.
