Abstract

PURPOSE:To obtain a lubricating device capable of increasing the supply oil pressure so as to certainly feed oil to a turbine bearing in emergency without any increase in the cost of equipment. CONSTITUTION:A pipe 54 bypassing a main oil pump 32 is provided with an auxiliary pump device 41, while the pipe 54 on a discharging side of the pump device 41 is provided with a check valve 42. A condenser 40 is provided with a pressure switch 43 which detects any increase in exchaust gas pressure of a turbine 37, a pipe 55 bypassing a pressure regulator valve 38 is provided with a bypass valve 44, and also a discharge side and an intake side of a auxiliary pump device 41 are connected by a test pipe 56, which is provided with a pressure vent valve 45. A starting switch 48 is opened or closed to a operate the auxiliary pump device 41 A starting switch 48 is opened or closed to operate the auxiliary pump device 41 by a signal from a pressure switch 47 or pressure switch 43 which detects a drop of discharge pressure of the main oil pump 32. The bypass valve 44 and a stop valve 46 linking to a system 57 are put in operation with operation of an air valve 49 which operates by a signal from the pressure signal 43.
