Abstract

The invention discloses a rectangular plunger of a radial plunger pump, and belongs to the field of hydraulic parts. The rectangular plunger is composed of a rectangular plunger body and a pin roller, wherein the pin roller is embedded into the rectangular plunger body, the rectangular plunger body is composed of a rectangular base body, and oil pools which are bilaterally symmetrical are arranged on the lower portions of the front end face and the rear end face of the rectangular base body. A damping hole communicated with the oil pool on the other side is machined in the oil pool on one side, a rotating groove penetrating in the left-right direction is formed in the upper portion of the rectangular base body, a short hole and a long hole penetrating from the rotating groove to the lower end face of the rectangular base body are sequentially formed in the rectangular base body, and the damping hole is communicated with the long hole. The pin roller is composed of a long shaft, and a stepped shaft is machined in the center of the long shaft. Inward-recessed embedding holes are formed in the end faces of the two sides of the long shaft. The rectangular plunger of the radial plunger pump has the beneficial effects that under the condition that the radial size is reduced, the displacement can be increased, and the rotating speed of the radial plunger pump can be better increased. The lubricating effect can be achieved with hydraulic oil in the oil pools, and rotary lubrication can be achieved through pressing of the pin roller and the outer surface at the same time.

Description

technical field [0001] The invention relates to a rectangular plunger of a radial plunger pump, in particular to a rectangular plunger of a radial plunger pump composed of a rectangular plunger body and rollers, belonging to the field of hydraulic components. Background technique [0002] Axial piston pumps have been widely used in the aerospace field due to their simple structure, small radial size, and high power density. Due to the current development of the plunger pump towards high speed and high pressure, the oil absorption capacity of the axial plunger pump gradually decreases with the increase of the speed. At the same time, the axial piston pump has poor adaptability to wide speed regulation and wide pressure range, and its efficiency is extremely low especially at low speed conditions. In order to make up for the disadvantages of the axial piston pump, a new type of rectangular plunger pump is proposed. The pump plungers are arranged radially. When the speed incre...
