Description
Известен способ изготовлени нераземного рабочего колеса радиально-осевой гидротурбины, при котором ободы и лопасти, изготовленные отдельно, собирают и сваривают вместе.A known method of manufacturing an indivisible impeller is a radial-axial hydraulic turbine, in which rims and blades, manufactured separately, are assembled and welded together.
Предлагаемый способ измен ет пор док сборки и сварки изготовленных отдельно верхнего и нижнего ободов с изготовленными отдельно лопаст ми гидротурбины.The proposed method changes the order of assembly and welding of the upper and lower rims manufactured separately with the turbine blades manufactured separately.
Скачала лопасти собирают и сваривают с неразъемный верхним ободом. После этого производ т одновременио . механическую обработку всех приваренных лопастей по кромкам, сопр ггаемым с иижним ободом Затем нижний обод надевают на обработанные кромки лопастей , закрепл ют его и сваривают с лопаст миThe downloaded blades are assembled and welded with a one-piece top rim. Thereafter, it is produced at the same time. machining of all welded blades along edges matched with the outer rim. Then the lower rim is put on the machined edges of the blades, secured and welded with blades.
Предлагаемый способ упрощает технологию изготовлени гидротурбин и повышает точность сборки н сварки ее.The proposed method simplifies the manufacturing technology of hydraulic turbines and improves the accuracy of assembly and welding of it.
