Description

Technical Field

[0001] This utility model relates to the field of steam turbine technology, specifically to a support device for steam turbine manufacturing. Background Technology

[0002] A steam turbine, also known as a steam engine, is a rotary steam power unit. High-temperature, high-pressure steam passes through a fixed nozzle, becomes an accelerated airflow, and is then injected onto the blades, causing the rotor, which is equipped with rows of blades, to rotate and perform work. Steam turbines are the main equipment in modern thermal power plants and are also used in the metallurgical industry, chemical industry, and ship propulsion systems.

[0003] During the manufacturing process of steam turbines, it is necessary to support and fix the turbine blade assembly. Existing support devices cannot stably support and fix the turbine blade assembly. Unstable support will lead to damage to the turbine blade assembly and cannot be applied to turbine blade assemblies of different sizes, resulting in high limitations in use. Utility Model Content
