Abstract

The invention discloses a piston pump, solving the problems that in the prior art, a piston pump is complex in structure and poor in efficiency. The piston pump comprises a shell, an oil outlet is formed in the shell, a pump core assembly is arranged in the shell, and at least one set of four-phase oil suction and discharge mechanism is arranged on the pump core assembly; an upper end cover and a lower end cover are arranged at the front end and the rear end of the shell respectively, and the front end of the pump core assembly is connected with a transmission mechanism arranged on the upper end cover; and an oil inlet corresponding to the pump core assembly is formed in the lower end cover. According to the piston pump, the two sets of four-phase oil suction and discharge mechanisms are adopted, four times of oil suction and discharge can be completed every time the four-phase oil suction and discharge mechanisms rotate by one circle, the mechanism is greatly simplified, the structure is simple, the weight is light, the rotor mass is light, the mechanical loss is small, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of pumps, in particular to a piston pump. Background technique [0002] Piston pumps are mainly used in oil circuit systems to provide high pressure and power drive for the system. Traditional hydraulic pumps mainly include gear pumps, vane pumps and plunger pumps. The gear pump mainly relies on the meshing of the gears to change the volume to realize oil suction and oil discharge. Although the hydraulic pump has a simple structure, it is heavy and has relatively high vibration and noise. The vane pump mainly relies on the rotation of the impeller, and uses centrifugal force to realize oil suction and oil discharge. Although the flow rate of this type of hydraulic pump is uniform and the noise is low, the blades are easy to seize, the structure is more complex than the gear pump, and the parts are manufactured with higher precision. The plunger pump is mainly composed of a pump body, a main shaft, a mandre...
