Abstract

The invention discloses a high-integration hydraulic power device composed of three parts, namely, a motor system, a pump integrated block and an oil tank. The motor system comprises a motor, a driverand a cooling fan. A constant-pressure variable-displacement plunger pump is embedded in the pump integrated block. Accessories such as a sensor are installed on a shell of the constant-pressure variable-displacement plunger pump. The oil tank is composed of a push rod, a spring, a piston and a membrane. The motor and the plunger pump share one main shaft. A motor main shaft directly drags and rotates a plunger pump rotor to complete the oil suction and oil discharge process of the plunger pump, flow of oil is regulated through a piston drawing type variable-displacement mechanism, and therefore the function of constant pressure and variable displacement can be achieved. The high-integration hydraulic power device is used as a power conversion device of an airplane and has the beneficialeffects of being simple in structure, small in weight, easy to control, high in system efficiency and convenient to maintain.

Description

technical field [0001] The invention relates to a hydraulic power device, in particular to a highly integrated hydraulic power device. Background technique [0002] The hydraulic power unit can convert the mechanical energy of the motor into high-pressure hydraulic energy, so it is widely used in some actuators of aircraft. [0003] The traditional hydraulic power unit has heavy weight, complex piping, unreasonable space layout and low reliability. Contents of the invention [0004] The purpose of the present invention is to provide a highly integrated hydraulic power device with simple structure, light weight, easy control, high system efficiency and convenient maintenance. [0005] The technical solution for realizing the object of the present invention is: a highly integrated hydraulic power device, which is composed of a motor system, a pump manifold, and a fuel tank. The pump manifold is in the middle, and the left and right sides are respectively connected to the fu...
