YDT系列电液调速器是第二代中型PID调速器,其电液转换器的电气—位移转换部分和引导阀合为一体。介绍了该系列电调的调节规律及残压测频电路、两段关闭装置的结构原理。
YDT series of electro-hydraulic governor is the second generation of medium-sized PID governor, the electro-hydraulic converter of the electric - displacement conversion and the pilot valve into one. The adjustment rules of the series electric regulation and the structure principle of the residual voltage frequency measurement circuit and the two-stage shut-off device are introduced.
