Безлопастная бездисковая турбина как компонент системы аварийной подпитки энергооборудования

Abstract

Рассмотрены дополнительные возможности повышения надежности действующих энергоблоков атомных электростанций посредством внедрения альтернативных и дополнительных систем подпитки тепломассообменного оборудования при возникновении дефицита водной среды в аварийных и предаварийных режимах. Предложено использование в составе комбинированного турбопривода насосного агрегата подпитки нового конструктивного компонента – бездисковой безлопастной турбины трения спирального типа.

As part of the complex problem of improving the reliability of the main technological equipment for nuclear power plants, provided that their functional and economic efficiency shows the solution practically important problem of improving the reliability of the emergency feed water heat exchange media in equipment. It is considered alternative and complementary feeding system, which is based on the idea of steam use of steam generators as motor power combined turbine drive pump unit, the feed water supply in the equipment which needs replenishing water loss. Proposed to use in the composition of the combined turbine drive new constructive component - diskless bladeless turbines with friction spiral type. Improving the efficiency of the device is ensured by the turbopump assembly constructive opportunities unstressed movement of the working body in the running part of the impeller and the turbine rotor, as a consequence, increase its intake capacity. The design of the proposed combined turbine drive should provide energy not only improve the reliability of nuclear power plant’s units, but also can promote their safety.
