Title:
OIL PRESSURE SYSTEM FOR STEAM TURBINE
Document Type and Number:
Japanese Patent JPS6158905
Kind Code:
A
Abstract:
PURPOSE:To simplify an oil pressure system and reduce its cost by interconnecting the oil pressure control system of a main steam turbine for driving a generator and that of a sub-steam turbine for driving a boiler water- supply pump. CONSTITUTION:The oil pressure control system of a main steam turbine 5 for driving a generator 7 is connected to that of a sub-steam turbine 9 for driving a boiler water-supply pump 11 and they are commonly actuated by a main oil pressure as one of its multiple missions. An oil line 53 of an oil pressure control system 51 for supplying lubricating oil to the bearing of the sub-steam turbine 9 is connected from an oil turbine 27 to an oil line 55 of an oil pressure control system 21 for supplying lubricating oil to the bearing of the main turbine. Furthermore, an oil line 59 of an oil pressure control system 57 for driving and controlling the sub-turbine is connected to an oil line 61 between main oil pump 23 and oil turbine 27. Thereby the oil pressure system can be simplified.
