液压测功器

By connecting the pilot valve of stepping electric motor with machinery and hydraulic servomotor device, it can form the stepping microcomputer-based governor for water turbine.

以工业控制级单片机 80C552 为核心，开发出集测频、调速、调功、开停机操作、故障诊断及与上位机通讯等功能于一体的双微机型电气调节器，并与抗油污能力强、定位精度高、漏油量小的步进电机式引导阀及机械液压随动装置相配接，构成了水轮机步进式微机调速器。
