Problems solved by technology

[0002] In the prior art, the binary impeller with narrow channel on the rotor of the oxygen compressor is usually connected by pure riveting or "brazing + riveting". In order to ensure sufficient space for riveting, the ideal channel design has to be changed, adding thicker and heightened; in addition, according to relevant international standards, it is forbidden to use impellers with riveted structures on oxygen compressors, which will pose safety hazards

Abstract

Provided is a narrow channel two-element working wheel for a turbocompressor. Blades are forged on a wheel disc through a semi-open type and closed type combined mode, and the wheel disc and a wheel cap are annularly connected through manual argon arc welding. The wheel cap and the blades are connected together through braze welding. The narrow channel two-element working wheel has the advantagesthat the welding strength is sufficient, a channel welding transition area is smooth, the unbalance amount is small and the appearance quality is high.

Description

technical field [0001] The invention relates to the technical field of working wheels, in particular to a narrow channel binary working wheel for a turbo compressor and a manufacturing method thereof. Background technique [0002] In the prior art, the binary impeller with narrow channel on the rotor of the oxygen compressor is usually connected by pure riveting or "brazing + riveting". In order to ensure sufficient space for riveting, the ideal channel design has to be changed, adding thicker and heightened; in addition, according to relevant international standards, it is forbidden to use impellers with riveted structures on oxygen compressors, which will pose safety hazards. Contents of the invention [0003] The purpose of the present invention is to open up new markets, improve the quality of a single product by upgrading the manufacturing equipment and improving the manufacturing process, thereby improving the efficiency of the whole machine and meeting the original ...
