Abstract

The invention discloses a highly-integrated pressure balance type deep sea electro-hydraulic servo mechanism and belongs to the technical field of deep sea electro-hydraulic servo. A spherical hinge rod end is arranged on an extending end piston rod through a spherical hinge rod end thread connection hole, a cylinder barrel combination piece and a valve block and pressure balance device combination piece are connected together through a screw, the valve block and pressure balance device combination piece and a balance piston placement barrel are connected together through a screw, a balance piston is put into the balance piston placement barrel, sea water and high-pressure oil are arranged at the front end and the rear end, the high-pressure oil enters the balance piston placement barrel through a high-pressure oil hole and is used for balancing the pressure of the whole system, four baffles are evenly arranged at the rear end of the balance piston placement barrel, and an emergency pipe connector is arranged on a piston rod pressure balance barrel and a cylinder bottom cover. The highly-integrated pressure balance type deep sea electro-hydraulic servo mechanism has the beneficial effects that pressure balance and a highly-integrated structure are adopted to the design and layout, meanwhile, the dual-redundancy design thought is adopted, reliability and safety are greatly improved, and the service life is greatly prolonged.

Description

technical field [0001] The invention relates to a highly integrated pressure-balanced deep-sea electro-hydraulic servo mechanism, which is composed of a drive controller, a motor, a plunger pump, a servo valve, a valve block, a pressure balance device assembly, and a balance piston placement cylinder. Deep sea electro-hydraulic servo technology field. Background technique [0002] The hydraulic system is widely used in traditional flight control and ship steering systems due to its advantages of large load, high specific force, and bootstrapping. However, with the development of science and technological innovation, problems such as low efficiency, high failure rate, and high maintenance cost have become increasingly prominent. Since the 21st century, with the development of new materials, motor technology, control science and advanced manufacturing technology, the flight control system has entered the era of power-by-wire. As the carrier of power transmission, the researc...
