COMBINED turbo-drive of ROTARY PUMP of a SYSTEM of EMERGENCY feeding of a nuclear power plant EQUIPMENT

摘要

Combined turbo-drive of rotary pump of a emergency equipment feeding system of nuclear power plant includes a friction turbine and axial blade steam turbine the impellers of which are mounted on the same shaft in interconnected through intermediate chamber sealed housings so that supply of wet steam to the turbine drive is constructively performed first to friction turbine and then to the axial steam turbine. In order to improve the efficiency of the device, due to steam dehumidification before the blade turbine by removing liquid separate from the engine case, in the intermediate camera zone the outputs to the condensate collector are provided, this is a part of the body and is equipped with a drainage system for discharge of condensate.
