摘　　要：在半舷外液压系统中,对回油路压力进行补偿是减少海水渗入系统,从而提高其可靠性的重要措施。提出了一种新型深海半舷外液压系统回油路压力补偿器,对其工作原理进行了阐述,通过对其工作过程进行分析和数学建模,详细介绍各个关键部分的结构参数设计。试验结果表明,该深海自适应压力补偿器在液压系统的不同状态下可实现连续压力补偿,维持压力始终大于外界海洋环境压力。In the semi-outboard hydraulic system,compensating the return oil pressure is an important method to reduce the seawater infiltration into the system and improve its reliability.In this paper,a new type of oil return pressure compensator for deep-sea semi-outboard hydraulic system is presented,and its working principle is described.Through the analysis and mathematical modeling of its working process,the structural parameter design of each key part is introduced in detail.The test results show that the deep-sea adaptive pressure compensator can realize continuous pressure compensation under different states of the hydraulic system,and the maintenance pressure is always greater than the external marine environment pressure.
