Abstract

The invention relates to a hydraulic system used for adjusting the buoyancy of a full-ocean-depth submersible. The hydraulic system comprises a hydraulic power source, a seawater hydraulic power source, a water ballast space and a water ballast space control valve set. The hydraulic power source drives the seawater hydraulic power source to work, and water injection or water drainage of the interior of the water ballast space is controlled through switching of the water ballast space control valve set, and thus adjusting of the buoyancy of the full-ocean-depth submersible is achieved. The hydraulic system is simple in structure and convenient to use; and a pressure cylinder of the hydraulic system is driven by oil pressure and outputs aqueous media, compared with traditional axial plunger type seawater pumps, the machining cost of the hydraulic system is low, and the flow is larger, the service life is long, the reliability is good and the volume efficiency is high with the same volume. The submersible buoyancy adjusting working condition of the hydraulic system has quite low requirements for pumping flow pulsation, the hydraulic system is better agree with the submersible buoyancy adjusting working condition than the axial plunger pumps, and the outlet pressure of the pressure cylinder can meet the full-ocean-depth application requirements by adjusting the pressure ratio of the pressure cylinder.

Description

technical field [0001] The invention relates to the field of submersibles, in particular to a hydraulic system for adjusting the buoyancy of a deep-sea submersible. Background technique [0002] Submersibles are important equipment for efficient exploration, scientific investigation, development operations, military detection and combat platforms. After the submersible is sampled, due to the increase in weight or the decrease in weight after releasing other equipment, or the change in seawater density due to the characteristics of the water medium (pressure, temperature); as the depth of the submersible increases, the pressure-resistant structure of the submersible Elastic deformation causes changes in displacement volume, and these factors cause the balance of gravity and buoyancy to be often disrupted. Therefore, in order to ensure that the submersible has a relatively stable operating attitude at a certain depth, it is necessary to adjust its buoyancy. [0003] At prese...
