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.

Abstract: Provided is a high-pressure cleaning machine, including a high-pressure water pump, a motor, a cover body and a water inlet of cleaning machine. The high-pressure water pump includes a shell, a driving mechanism, an isolation member, at least one plunger, and at least one plunger cavity. The driving mechanism includes a main shaft and at least one eccentric member. At least one side of the main shaft is rotatably connected to the shell via a rolling bearing. The motor is configured to drive the main shaft of the high-pressure water pump to rotate, so that the eccentric member pushes the plunger to move in the plunger cavity to pressurize water or an aqueous solution. The motor is provided with a flow channel. The flow channel is configured for the water or aqueous solution entering through the water inlet of cleaning machine to flow through.

Abstract: A high-pressure water pump lubricated by water or aqueous solution is provided, relating to the technical field of high-pressure plunger pumps. The high-pressure water pump includes a driving mechanism, at least one plunger, a plunger cavity, and a shell. The driving mechanism includes an eccentric wheel shaft and thrust rings. The eccentric wheel shaft includes a main shaft and multiple eccentric wheels arranged on the main shaft. The eccentric wheels are integral eccentric wheels and combined eccentric wheels, respectively. Compared with an original combined eccentric wheel structure mode, the eccentric wheel shaft provided by the present disclosure obviously improve anti-deflection characteristics of the main shaft, and thereby prolongs the service life of the high-pressure water pump. Moreover, the thrust ring structure can be conveniently installed, the structure is simple and compact, and the weight is light.
