Gas turbine oil supply system and method for operating a gas turbine store oil supply

摘要

The system has a supply line (2) diverted from an oil tank (1), and an electrical oil pump (3) arranged in the supply line. A controllable diverting element (4) i.e. multi-port-valve, is arranged downstream to the oil pump. Oil flow is recycled through the controllable diverting element via a return pipe (5) into the oil tank. The electrical oil pump is provided with an additional heating element. The electrical oil pump and the diverting element are activated for recirculation of the oil via the return pipe during lowering of a predetermined value. An independent claim is also included for a method for operating a bearing-oil-supply of a gas turbine.
