Abstract

Целью работы является эскизное проектирование проточной части такого цилиндра высокого давления для турбины типа К-800-240. Для достижения поставленной цели необходимо выполнить газодинамические расчеты проточной части и расчет осевого усилия, действующего на ротор ЦВД, произвести прочностные расчеты отдельных элементов турбоустановки и разработать эскиз конструкции цилиндра высокого давления. ВКРсостоит из шести основных глав. Первая глава посвящена компьютерной оптимизации двухвенцовой ступени скорости ЦВД. Во второй главе представлен проектировочный газодинамический расчет реактивных ступеней давления ЦВД. В третьей главе определено осевое усилие, действующее на ротор ЦВД. В четвертой главе приведено описание эскиза проточной части ЦВД на суперсверхкритические параметры пара. Пятая глава посвящена профилированию рабочей лопатки последней ступени ЦВД. В шестой главе проведен расчет рабочей лопатки последней ступени на прочность. Прочностные расчеты производятся средствами программных пакетов ANSYS и MathCad.

The aim of the work is a draft design of the flow-through part of such a high-pressure cylinder for a K-800-240 turbine. To achieve this goal, it is necessary to perform gas-dynamic calculations of the flow-through part and the calculation of the axial force acting on the high-pressure cylinder rotor, make strength calculations of individual elements of the turbine unit and develop a sketch of the high-pressure cylinder design. WRC consists of six main chapters. The first chapter is devoted to computer optimization two-part stage of speed CHP. The second chapter presents the design gas-dynamic calculation of the reactive pressure stages of the high-pressure cylinder. The third chapter defines the axial force acting on the rotor CHP. The fourth chapter describes the design of the flow section of the CHP for super-critical steam parameters. The fifth chapter is devoted to the profiling of the working blade of the last stage of the CHP. The calculation for strength of the working blade of the last stage conducted in the sixth chapter. Strength calculations are made by means of the software packages ANSYS and MathCad
