Abstract

The invention discloses a high-strength turbine blade. The high-strength turbine blade comprises a blade surface, a blade root and a blade top, wherein the upper part of the blade surface is connected with the blade top; the lower part of the blade surface is connected with the blade root through a connecting piece; a square air concentration channel is arranged on the blade surface; air vents are formed around the square air concentration channel; a lacing hole is formed in the middle part of the blade surface; the width of the blade surface is gradually decreased from the blade root to the blade top; and the blade surface is manufactured through high-strength steel. According to the high-strength turbine blade, the manufacturing cost is low, the working efficiency is high, and the strength is high.

Description

technical field [0001] The invention relates to the technical field of steam turbine blade devices, in particular to a high-strength steam turbine blade. Background technique [0002] The steam turbine blade is an important part of the steam turbine generator set. The steam turbine blades commonly used in the market generally improve the working efficiency by changing the shape of the blade, but the effect is not obvious, and the maximum working efficiency of the blade has not been exerted. And the existing steam turbine The blades are expensive to manufacture, are easily damaged by corrosion, have a short service life, and are expensive to maintain. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a steam turbine blade with low manufacturing cost, high work efficiency, anti-rust and high strength for the above shortcomings of the prior art. [0004] The technical solution of the present invention to solve the ab...
