摘要
随着液压系统的功能、规模、复杂程度逐步提高,液压系统故障比率也随之增加。为提高液压系统的可靠性与安全性,对系统液压油产生颗粒污染时锚机液压泵出口管路的内部流场进行研究;设计不同颗粒污染等级的管路流动方案,采用Fluent对模型内部的流场进行模拟;基于边界层理论,对液压管路污染等级进行评估。为从整体上提高船舶液压设备的状态检测和船舶智能化水平提供了条件。
As the function,scale and complexity of the hydraulic system gradually increase,the failure rate of the hydraulic system also increases.In order to improve the reliability and safety of the hydraulic system,the internal flow field of the outlet pipe of the anchor machine hydraulic pump was studied in the case of the system hydraulic oil produced particle pollution.Pipeline flow schemes with different particle pollution levels were designed,and Fluent was used to simulate the flow field inside the model.The pollution level of hydraulic pipeline was evaluated based on boundary layer theory.It provides conditions for improving the level of ship hydraulic equipment state detection and the ship intelligence on the whole.
