低能耗低振动浮调海水泵装置研究OA

To meet the requirements of weight-adjustable buoyancy adjustment systems for autono-mous underwater vehicles regarding low energy consumption and low vibration during operation,a low-energy seawater pump with load-adaptive capability was developed.Guided by the principle of low-vibra-tion design,the selection of key components and the optimization of structural parameters were completed.Addressing its dynamic behavior under varying load conditions,a load-adaptive control strategy based on volumetric control principles was constructed.This strategy enables the automatic adjustment of the sys-tem's working pressure in response to changes in external load,thereby significantly reducing energy con-sumption.In addition,a coordinated control mechanism for the proportional directional valve and the servo motor was designed,achieving precise control over the reversing process of the hydraulic cylinder,thereby further reducing system vibration and impact.Through simulation analyses and prototype experiments,the device's excellent load-adaptive regulation capability and operational stability were verified under typical load conditions(0 MPa and 10 MPa).These results demonstrate that it possesses strong potential for engi-neering application in deep-sea environments.
