FIELD: power engineering.
SUBSTANCE: invention relates to power engineering. Method of controlling hermeticity of vacuum systems of turbo-installations through which at points of steam flow of excess pressure is determined visually looseness vacuum system, at that crimping of steam of low and medium-pressure cylinder extraction turbine plant and connected to the cylinders of the capacitor, system water heaters and regenerative low pressure heaters is performed on hot turbine, immediately after stopping, steam overpressure, which is fed into cylinder when the shaft-turning device of turbine plant at open turning control diaphragm, at closed shutoff valves on steam extractions to feed water deaerator and heaters of high pressure and at open shutoff valves on steam extractions to network heaters and regenerative heaters of low pressure.
EFFECT: higher reliability and economy of thermal power plants.
