摘要
当海水深度超过10000 m时,海水环境压力大于100 MPa。环境高压会引起液压油体积变化、黏度特性等参数的变化,均对液压系统的控制和输出特性产生不可忽视的影响,因运行环境特殊,如何选择液压油暂无参照标准。针对上述问题,从工作环境、选择因素、液压油选择评定等方面进行论述,通过开展模拟高压环境下液压油黏度特性和体积变化等试验测试分析,为深海液压系统的设计提供直接参考。
When the depth of seawater is more than 10000 meters,the ambient pressure of seawater is more than 100 MPa.The high ambient pressure will cause changes in the volume and viscosity of the hydraulic fluid,which will have a non-negligible effect on the control and output characteristics of the hydraulic system.Due to the special operating environment,there is no reference standard for the selection of hydraulic fluid.In order to address the above problems,we discuss the working environment,selection factors,hydraulic fluid selection evaluation,etc.By simulating the viscosity characteristics and volume change of hydraulic fluid under high-pressure environment,we can provide a direct reference for the design of deep-sea hydraulic system.
