SYSTEM AND METHOD FOR REGULATING PRESSURE FOR A TURBOMACHINE Russian patent published in 2019 - IPC F01D25/20 F01D25/18 F01M1/16 

FIELD: machine building.

SUBSTANCE: pressure regulating system 10 which is in arrangement with a turbo machine, for example, a nuclear steam turbine 180. Main lubricant oil pump 190 supply fluid, for example, lubricant oil to nuclear steam turbine 180 passes through cooler 200 and via filter 210 through main supply line 310. Pressure regulating system 10 is connected to main supply line 310 through actuating line 60. Based on requirement of the fluid excessive fluid can be diverted through actuating line 60 to pressure regulating system 10 and from there to oil tank 220. In oil tank 220 an auxiliary lubricant oil pump 230 is provided to supplement the supply of the lubricant oil to nuclear steam turbine 180. Emergency lubricant oil pump 240 has also been provided to supply the lubricant oil to nuclear steam turbine 180 in case when regular supply is not working.

EFFECT: object of the present disclosure is to propose a system and method for regulating the pressure in a turbo machine particularly nuclear steam turbine which can be used in existing and in new unit installations to significantly reduce the emission of these pollutants.
