摘　　要：介绍采用自容式电液伺服系统对氨气制冷压缩机汽轮机液压调节系统进行改造,自容式电液伺服系统是一种油源独立、输出刚度大、定位精度高、动态响应快以及集成设计自成一体的电液伺服闭环控制系统,改造后实现了汽轮机速关阀和调节阀的全自动控制,提高了机组控制精度和运行安全性。The retrofits of ammonia refrigeration turbine compressor by a self-contained electro-hydraulic actuator are introduced in this paper. This actuator integrated with oil supply and servo control unit,have the advantages of large output stiffness,high positioning accuracy,fast dynamic response,and can achieve all the automation control command of main throttle valve and governing servo-motor,so greatly improved the control performance and operating safety of the turbine unit.
