(54) СПОСОБ ИЗГОТОВЛЕНИЯ СВАРПОГО РАБОЧЕГО КОЛЕСА РАДИАЛЬНО-ОСЕВОЙ ГИДРОМАШИНЫ(54) METHOD OF MANUFACTURING A WELDING OPERATING WHEEL OF RADIAL-AXIAL HYDRAULIC MACHINES
.1.one
Изобретение относитс к гидромашиностроению и может быть использовано при изготовлении рабочих колес радиально-осевых гидромашин.The invention relates to hydraulic engineering and can be used in the manufacture of impellers radial-axial hydraulic machines.
Известен способ изготовлени сварного рабочего колеса радиально-осевой гидромашины с седлообразным составным нижним ободом, включающий приварку лопастей к верхнему ободу, последующую обработку кромок лопастей и нижнего обода по поверхности их сопр жени и приварку последнего к лопаст м 1.A known method of manufacturing a welded impeller is a radial-axial hydraulic machine with a saddle-shaped composite lower rim, including welding the blades to the upper rim, subsequent processing of the edges of the blades and the lower rim along the surface of their coupling and welding the latter to the blade m 1.
Однако недостатком этого способа вл етс то, что при сварке установленных на лопасти частей нижнего обода не обеспечиваетс требуема точность внутренней поверхности нижнего обода.However, the disadvantage of this method is that when welding parts of the lower rim mounted on the blade, the required accuracy of the inner surface of the lower rim is not ensured.
Цель изобретени - повышение точности изготовлени сварного рабочего колеса радиально-осевой гидромашины.The purpose of the invention is to improve the manufacturing accuracy of a welded impeller of a radial-axial hydraulic machine.
Указанна цель достигаетс тем, что обработку кромок лопастей от наименьшего диаметра поверхности сопр жени к торцу лопастей с минимальным крайним диаметром осушествл ют по цилиндрической поверхности , и перед приваркой нижнего обода к лопаст м его части сваривают между собой, а цилиндрическую поверхность лопастей наплавл ют до седлообразной.This goal is achieved by machining the edges of the blades from the smallest diameter of the mating surface to the end of the blades with the minimum outer diameter, along a cylindrical surface, and before welding the lower rim to the blade, its parts are welded to each other. .
На чертеже схематически показано сварное рабочее колесо радиально-осевой гидро машины, продольный разрез.The drawing shows schematically a welded impeller of a radial-axial hydro machine, a longitudinal section.
Рабочее колесо радиально-осевой гидромашины содержит верхний обод 1 с приваренными к нему лопаст ми 2 с наименьшим диаметром d поверхности сопр жени The impeller of the radial-axial hydraulic machine contains the upper rim 1 with blades 2 welded to it with the smallest diameter d of the mating surface
10 и минимальным крайним диаметром d, к кромкам 3 которых приварен седлообразный составной нижний обод 4.10 and the minimum outer diameter d, to the edges of which 3 is welded the saddle-shaped composite lower rim 4.
Способ осушествл ют следующим образом .The method is carried out as follows.
Лопасти 2 приваривают к верхнему обо15 ду 1. Кромки 3 лопастей 2 обрабатывают от наименьшего диаметра d поверхности сопр жени к торцу лопастей с минимальным крайним диаметром d, по цилиндрической поверхности , сваривают из частей нижний обод 4,The blades 2 are welded to the upper equipment 1. The edges 3 of the blades 2 are machined from the smallest diameter d of the mating surface to the end of the blades with the minimum extreme diameter d, along a cylindrical surface, welded from the lower rim parts 4,
20 обрабатывают его внутреннюю поверхность, устанавливают нижний обод 4 на кромках 3 лопастей 2, перед приваркой нижнего обода 4 к лопаст м 2 наплавл ют цилиндрическую поверхность кромок 3 лопастей 2 до20 process its inner surface, install the lower rim 4 on the edges 3 of the blades 2, before welding the lower rim 4 to the blade m 2 weld the cylindrical surface of the edges 3 of the blades 2 to
седлообразной, и приваривают нижний обод 4 к лопаст м 2.saddle-shaped, and weld the lower rim 4 to the blade m 2.
Такой способ позвол ет за счет увеличени точности изготовлени предлагаемых радиально-осевых гидромашин повысить КПД и увеличить выработку электроэнергии.Such a method allows, by increasing the accuracy of manufacturing the proposed radial-axial hydraulic machines, to increase efficiency and increase power generation.
