[目的]浮力调节系统是控制水下滑翔机潜浮状态及滑翔速度的关键组件。为了深入研究浮力调节系统,[方法]通过对水下滑翔机及其浮力调节系统的理论分析和CFD计算,以获得浮力调节量这一重要的设计参数。研制了具有出油和回油两通路的浮力调节系统、采用高压柱塞泵实现在深水环境下向外出油、低能耗齿轮泵实现在浅水环境下回油的浮力调节系统。在不同压力环境下对出油和回油特性及其能耗进行实验测试。[结果结果]结果表明:在2.5 MPa压力环境下,浮力调节系统出油过程正常;在大气压力环境下,浮力调节系统的回油过程正常,所研制的实验装置可模拟水下滑翔机实际运行环境的海洋压力。[结论]研制工作可为浮力调节系统的工程应用提供有益参考。

[Objectives]Buoyancy regulating system is a key component of an underwater glider for controlling submerging and surfacing statuses and gliding speed of the underwater glider.To further study the buoyancy regulating system,[Methods]we carry out theoretical analysis and CFD for the underwater glider and its buoyancy regulating system to obtain the buoyancy regulating value,which is an important design parameter;develop a buoyancy regulating system with both oil outlet and oil return passages,that is,a high-pressure plunger pump for oil outlet in deep water and a low-energy gear pump for oil return in shallow water.We conduct the tests for the oil outlet and oil return characteristics and the energy consumption under different pressure conditions.[Results]The results show that the oil outlet is normal under the pressure of 2.5 MPa and the oil return is normal under atmospheric pressure.The developed test device can simulate the marine pressure in the actual operating environment of the underwater glider.[Conclusions]The study results can provide useful references for the engineering application of the buoyancy regulating system.
