摘要: 水压电磁溢流阀是高精度控制和深海远程控制的关键元件之一,本文在充分考虑海水介质理化特性分析的前提下给出了先导式纯水液压电磁溢流阀的结构,针对纯水液压溢流阀的关键技术(气蚀问题、密封与润滑、腐蚀、)提出设计要点及解决方案,并根据介质水的物理性质及摩擦磨损试验初步选取溢流阀关键部位的所需材料。在油压溢流阀试验系统的基础上设计出水压溢流阀的试验系统,然后对水压电磁溢流阀进行静、动态性能试验分析。本文设计的溢流阀具有压力超调量小,动态响应较好等特点,其调压范围是0.5 MPa~9 MPa。Abstract: Water hydraulic piloted solenoid relief valve is one of the key components in high-precision and deep-see remote control.The structure of relief valve and its work principle is briefly introduced by taking full account of the physical and chemical properties of seawater,and the main design points of pure water hydraulic relief valve are proposed.According to the physical properties of medium water and the results of friction and wear tests,the key parts materials of relief valve are selected.Experimental system of pure water hydraulic relief valve is designed with reference to the oil hydraulic relief valve,and both the static characteristics and dynamic characteristics tests of the pure water hydraulic relief valve is conducted.From the tests it can be seen that the design pressure range of relief valve is 0.5 MPa~9 MPa,and its overshoot of pressure is low,dynamic response is fast.
