Проектирование Ð¼ÐµÑ Ð°Ð½Ð¸Ð·Ð¼Ð° поворота лопастей рабочего колеса гидротурбины ПЛ 50

Abstract

Тема выпускной квалификационной работы: «Проектирование механизма поворота лопастей рабочего колеса гидротурбины ПЛ 50».Данная работа посвящена проектированию механизма поворота лопастей рабочего колеса для поворотно-лопастной гидротурбины. По исходным данным была построена рабочая зона гидротурбины, затем по полученной зоне работы гидротурбины были определены углы установки лопастей рабочего колеса.Для расчета усилий сервомотора, требуемых для поворота лопастей были рассчитаны силовые характеристики рабочего колеса: гидравлический момент, значения осевого и окружного гидравлических усилий, которые действуют на лопасть рабочего колеса ПЛ 50 гидротурбины.В программе Solid Works были спроектированы детали механизма поворота механизм поворота лопастей рабочего колеса и был произведен расчет на прочность корпус рабочего колеса в программе Ansys в разделе Static Structural.При проектировании были использованы инженерные методы, принятые в теории машин и механизмов. При расчете на прочность использован метод конечных элементов и программный комплекс Ansys.В результате проведенной работы был спроектирован кривошипно-шатунный механизм поворота лопастей рабочего колеса, который позволяет осуществлять регулирование работы гидротурбины на заданных мощностях.

The subject of the graduate of qualification work is « Design of the blade adjustment mechanism of Kaplan turbines under head 50».This work is devoted to the design of the adjustment mechanism of the runner blades for Kaplan hydraulic turbine. According to the initial data, the working area of the hydraulic turbine was built, then the angles of the runner blades were determined based on the obtained working area of the hydraulic turbine.To calculate the servomotor forces required to rotate the blades, the power characteristics of the runner were calculated: hydraulic torque, values of axial and circumferential hydraulic forces that act on the runner blade of the hydraulic turbine.In the Solid Works program, the details of the adjustment mechanism were designed, the adjustment mechanism the runner blades and the stress of the runner hub was calculated in the Ansys program in the Static Structural section.Engineering methods adopted in the theory of machines and mechanisms were used in the design. When calculating the stress, the method of finite elements and the Ansys software package were used.As a result of the work carried out, a crank-connecting rod the blade adjustment mechanism of Kaplan turbines was designed, which allows regulating the operation of the hydraulic turbine at specified capacities.
