巨型水轮机调速器比例集成式电液随动装置

Proportional integrated electrohydraulic servo-positioner suitable for giant turbine governor

根据巨型水轮机调速器对电液随动装置的主要技术要求 ,在分析对比了国内外若干电液随动装置特点的基础上 ,充分利用现代先进的电液控制技术 ,采用了以电子调节器型系统结构为主 ,以中间接力器型系统结构为辅的调速器系统结构方案。该方案具有运行可靠、指标优越、功能完备、结构简洁以及冗余度较高、便于提高工作油压和实现液压集成化等特点 。

On the basis of analysis and comparison of the performances of several electrohydraulic follow up devices both at home and abroad,and fully utilizing modern advanced electrohydraulic controlling technology,the scheme of the governor system structure,which takes the eletric governor system structure as the main part and intermediate servomotor as the auxiliary one ,is determined by the requirements of the giant turbine governor for the main technology of the electrohydraulic follow up device.With the characteristics of the reliable operation,advantage index,perfect function,simple structure,high degree of the redundance,convenient for increasing working oil pressure and implementing hydraulic pressure integration,this scheme offers a selective new mode of the electo hydraulic follow up device for the giant turbine governor.
