AN ELECTRO-HYDRAULIC CONVERTER FOR TURBINE CONTROL IN ELECTRO-HYDRAULIC GOVERNING SYSTEM OF STEAM TURBINES

摘要

This invention relates to an electro-hydraulic converter for turbine control in electro-hydraulic governing system of steam turbines comprising of proportional valve, manifold plate, piston, casing and position transmitter wherein the control signals from electro- hydraulic controller operates on proportional valve and control fluid is admitted to the valve through manifold plate resulting in corresponding mechanical displacement of piston.
