摘要
通过分析双喷嘴挡板式电液伺服阀的结构及工作原理,从力矩马达、前置级喷嘴挡板阀、功率级滑阀、液压油及密封件入手,深入研究各组成部分在温度影响下的特性变化及故障发生机理,为电液伺服阀的温度特性研究奠定了一定的基础。
This paper analyzes basic structure and working principle of double nozzle flapper electro-hydraulic servo valve, and then changing characteristics and failure mechanism of the torque motor, nozzle flapper prototype valve, power stage valve, hydraulic oil and sealig element under the temperature are deeply studied. This would lay the certain theoretical foundation for the study of temperature characteristics of electro-hydraulic servo valve.
