Abstract

PURPOSE: To start an emergency oil pump to assure bearing oil, by providing a pressure switch in a pipe between a booster pump and a main oil pump directly coupled to a turbine shaft.
CONSTITUTION: The pressure of pressurized oil discharged from a booster pump 1 is increased by a main oil pump 2. The pressure-increased oil is introduced to booster pump oil turbine 4 so that the pressure-decreased oil is supplied to a bearing 7. The set level of a pressure switch 20 in a pipe 3 is made higher than such decreased suction pressure of the main oil pump 2 that is cannot work. An emergency oil pump 10 is started by the switch 20. When the rotational frequency of the main oil pump 2 falls, abnormality is detected to start the emergency oil pump 10 to assure bearing oil before working oil and the bearing oil are instantaneously lost due to the disappearance of the suction of the main oil pump 2. This results in heightening the safety of turbine operation.
