Abstract

The invention relates to the field of control equipment of an actuator, and discloses a bidirectional electromechanical static pressure control device. The bidirectional electromechanical static pressure control device comprises a motor pump assembly, a hydraulic oil tank and an integrated valve block which are arranged on a supporting plate, wherein the integrated valve block is provided with a control valve assembly; the motor pump assembly comprises a double-output-shaft motor; output shafts on two sides of the double-output-shaft motor are connected with a first screw pump and a second screw pump correspondingly; low-pressure oil openings of the first screw pump and the second screw pump are both connected with the hydraulic oil tank; high-pressure oil openings of the first screw pump and the second screw pump are connected with a first oil path and a second oil path correspondingly; the first oil path is used for being connected with an oil cavity of the actuator; and the second oil path is used for being connected with another oil cavity of the actuator. The motor pump is formed by the two screw pumps and the double-output-shaft motor, and when the bidirectional electromechanical static pressure control device works on the actuator, the vibration of the bidirectional electromechanical static pressure control device and air noise are lowered.

Description

technical field [0001] The invention relates to the field of actuator control equipment, in particular to a bidirectional electromechanical static pressure control device. Background technique [0002] High-pressure screw pumps on the market have excellent static pressure performance and small pressure fluctuations, but generally they can only build up pressure in one direction, and the pressure difference between the high and low pressure ports of the pump cannot be reversed. The electromechanical static pressure system controls the movement direction of the actuator by controlling the forward and reverse rotation of the pump. Generally, a bidirectional pump is used, and it is required that the pump can build pressure in both forward and reverse rotations; however, bidirectional pumps on the market, such as plunger pumps, Gear pumps have the disadvantages of high noise and large pressure pulsation. Contents of the invention [0003] (1) Technical problems to be solved ...
