Problems solved by technology

[0004] First of all, since the existing hydraulic pump is installed outside the system, the volume of the system will be increased, so that the installation of the system requires more installation space; secondly, the oil circuit of the existing hydraulic pump is connected to the system through a pipe joint, which increases the risk of oil leakage. point, causing the hydraulic pump to easily leak oil; again, the pump cavity of the existing hydraulic pump is sealed by the shell, and the oil in the pump cavity enters and exits through the oil return port, and the oil return is small, and the heat in the pump cavity is difficult to quickly return to The oil port is taken away, the hydraulic pump is easy to burn the pump
[0005] Therefore, the existing hydraulic pump has the defects of increasing the installation space required for system installation, easy oil leakage and easy pump burning

Abstract

The invention discloses an embedded hydraulic pump. The embedded hydraulic pump comprises a main body (1); the main body (1) is provided with a revolving body type shell (2); sealing rings (4) are arranged at two ends of the shell (2); an annular concave surface (3) positioned on the peripheral surface of the shell (2) is arranged between the two sealing rings (4); the annular concave surface (3)is provided with a through hole (5) positioned on the side wall of the shell (2); the through hole (5) is connected with a pump cavity of the main body (1); a mounting edge (6) is arranged at one endof the shell (2); an oil inlet (7) and an oil outlet (8) are arranged at the other end of the shell (2); an oil inlet counter bore (9) is formed in the oil inlet (7); and an oil outlet counter bore (10) is formed in the oil outlet (8). The embedded hydraulic pump has the advantages of no adding of the mounting space needed for system installation, difficult oil leakage and difficult pump burnout.

Description

technical field [0001] The invention belongs to the field of hydraulic pumps or hydraulic motors, in particular to an embedded plug-in hydraulic pump. Background technique [0002] As one of the core power components and actuators of the hydraulic control and transmission system (hydraulic control and transmission system referred to as the system), the hydraulic pump or hydraulic motor is crucial to the system. It provides high-pressure hydraulic energy or Mechanical energy enables the system to adjust in real time according to instructions, ensuring the completion and safety of system tasks. From a structural point of view, the hydraulic pump is a hydraulic motor. From the specific use status, when the hydraulic pump is driven by the motor to output hydraulic energy, the hydraulic pump realizes the function of the hydraulic pump. When the hydraulic pump outputs mechanical energy through the action of pressure oil, the hydraulic pump The pump fulfills the function of the hy...
