Abstract

The invention discloses a full depth buoyancy regulating seawater pump, which mainly comprises a flat valve module, a plunger piston shoe module, a plunger sleeve, a force transfer and reset mechanism and a pressure compensator, wherein the pressure compensator is used for balancing a lubricating cavity and environmental stress; the force transfer and reset mechanism drives the plunger piston shoe module to alternately cycle for a pressing travel and a sucking travel, so that the flat valve module alternately cyclically sucks water and presses water; the plunger piston shoe module has a fixed interval forced reset structure, so that a plunger is reset reliably; the force transfer and reset mechanism has a bidirectional stress structural design, so that the seawater pump meets the special working condition of regulating the buoyancy by the hydraulic pressure of seawater; and a stepped plunger is adopted, large and small plungers are connected through a spherical hinge, and the problems of strength design, sealing and frictional wear of the crucial friction pair, namely an ultrahigh pressure seawater pump are solved. The full depth buoyancy regulating seawater pump can regulate the buoyancy of a submersible in sea areas with all depth, and has the characteristics of simple structure, high applicability and working reliability.

Description

technical field [0001] The invention belongs to volumetric hydraulic pumps, in particular to a plunger hydraulic pump, and more specifically to a full-depth seawater hydraulic buoyancy-adjusting seawater pump. technical background [0002] With the depletion of terrestrial resources, the eyes of the whole world are shifting to the oceans, which occupy the vast majority of the earth, in order to seek the energy, minerals and food resources needed for human survival. [0003] The development of the ocean needs to be based on high-tech marine equipment. Among them, various submersibles are the main equipment for ocean development, and they are important equipment for efficient ocean exploration, scientific investigation, development operations, military detection and combat platforms. [0004] After the submersible is sampled, the weight of the submersible increases or the weight decreases after the deployment of other equipment, or due to the change of seawater density due to ...
