目前对海水液压马达的研究主要集中在柱塞马达和叶片马达上，很少对低速大扭矩海水液压马达进行研究。低速大扭矩海水液压马达作为一种能量转换装置和执行器，在海水液压传动系统中起着重要的作用。然而，海水的低粘度、高腐蚀性、润滑性差等物理化学特性导致了许多问题。本文研究了海水液压马达配流副的流量分布特性，建立了配流副的泄漏流量和功率损失模型。通过数值模拟研究了水膜、进口压力和转速对压力分布和泄漏流量的影响。并对配流副进行了摩擦磨损试验。搭建了海水液压马达试验系统，并对样机进行了空载和加载工况下的性能测试。结果表明：配流副间隙和进口压力对配流特性有显著影响，转速对配流特性的影响不是很明显；实验结果表明，该流动模型的最小误差率可控制在0.3%以内，316L对碳纤维增强聚醚醚酮（CFRPEEK）对料适用于海水液压马达配流副。最后，基于海水水力实验平台，获得了空载和加载时的容积效率，最大可达到94.71%和90.14%。研究工作可改善配流性能、润滑性能和摩擦磨损性能，提高配流副的能量转换效率，为高性能水液压元件的设计提供理论和技术支持。
The current research of seawater hydraulic motor mainly focused on piston motor and vane motor, but seldom regarded low speed high torque seawater hydraulic motor. Low speed high torque seawater hydraulic motor as a kind of energy conversion device and actuator plays an important role in seawater hydraulic transmission system. However, the physical and chemical properties of seawater, such as low viscosity, high causticity and poor lubrication, result in numerous problems. In this paper, the flow distribution characteristics of port plate pairs for the seawater hydraulic motor are investigated, and the leakage flow and power loss models of port plate pairs are established. Numerical simulations are carried out to examine the effects of water film, inlet pressure and rotating speed on the pressure distribution and leakage flow. And the friction and wear tests of port plate pairs are also carried out. Moreover, the test system of the seawater hydraulic motor is constructed and the performance of prototype with no-load or loading is conducted. The results indicate that the clearance of port plate pairs and inlet pressure have a significant effect on distribution characteristics, but the effect of rotating speed is not very obvious. The experimental results show that the minimum error rate can be maintained within 0.3% by the proposed flow model and the counter materials of 316L against carbon-fiber-reinforced polyetheretherketone (CFRPEEK) are suitable for the port plate pairs of seawater hydraulic motor. Finally, based on the seawater hydraulic experiment platform, the volumetric efficiency of no-load and loading are obtained that the maximum can achieve 94.71% and 90.14%, respectively. This research work may improve the flow distribution performance, lubrication and the friction and wear properties, enhance energy converting efficiency of port plate pair and provide theoretical and technical support for the design of high-performance water hydraulic components.
