High Quality Speed Control Governor For Hydraulic Turbine

High Quality Speed Control Governor For Hydraulic Turbine

Speed Control Governor For Brief Introduction

The YWT type product instruction microcomputer governor is a new governor for hydropower station, and its simple structure, high reliability, powerful function, fine adjustment performance, strong anti-disturbance performance etc. had solved that poor anti-disturbance performance, electric -hydraulic converter easy to be blocked, multifarious lever mechanism etc, In previously governor shown, so that this governor can auto-operate reliability and stably and to facilitate the turbine generator units control up to no-operation state.

Speed Control Governor For Hydraulic Turbine Application Scope
