Abstract

The invention discloses an electric static liquid actuator for deep sea. An integrated-type integrated structure is adopted. The movement of a hydraulic cylinder is controlled by a two-way hydraulic pump. The forward and reverse of a motor is adjusted and controlled, and the displacement and accelerated speed of a piston rod of the hydraulic cylinder are controlled through speed regulation operation; and a hydraulic direction-changing valve, a reducing valve and other control valves are cancelled, and an arranged sensor monitors and adjusts the working condition of a system. A pressure compensator is arranged outside the system and used for compensating system pressure and adapting high pressure environment of the deep sea. A hydraulic circuit adopts a plate-type connection without external connection pipelines, only an interface for power supply and signal transmission is arranged on the exterior of the hydraulic circuit, the advantages of a hydraulic actuating system and an electricactuating system are both had, system composition is simplified greatly, and the equipment volume is greatly reduced. Therefore, the electric static liquid actuator for the deep sea has a wide application prospect in deep-sea operating equipment and shipping equipment.

Description

technical field [0001] The invention relates to an electrostatic fluid actuator for deep sea, which is an executive mechanism of a power transmission system and belongs to the technical field of fluid transmission and control. Background technique [0002] The underwater hydraulic system is the application of hydraulic technology in the field of marine engineering. The traditional centralized oil source deep-sea hydraulic system adopts throttling and speed regulation technology, which has a large volume and weight, which is not conducive to modular design, and is prone to leakage, low efficiency and complex structure. and other shortcomings limit its further development. With the development of electronic power and control technology, the continuous development of new materials, modern technology gradually affects hydraulic technology. The electric hydrostatic actuator proposed by the present invention has high integration, small volume, high efficiency It has high advantage...
