Assembling type steam turbine casing

Abstract

The invention belongs to the technical field of machinery and particularly relates to an assembling type steam turbine casing which solves the problem that an existing steam turbine casing is inconvenient to disassemble and assemble, low in structural strength and the like. The assembling type steam turbine casing comprises a frame body formed by assembling frame body section bars in detachable mode, an opening for a steam turbine to pass in and out is arranged at the top of the frame body, a top frame formed by assembling top frame section bars in detachable mode is connected at the position of the opening in detachable mode, a plurality of side plates capable of sealing the periphery of the frame body is assembled on the periphery of the frame body in detachable mode, a plurality of hollow cover plates capable of covering the opening are assembled on the top frame in detachable mode, and a power outlet for outputting power of the steam turbine is arranged at one end of the frame body. Compared with the prior art, the assembling type steam turbine casing has the advantages of being reasonable in design, compact in structure, convenient to disassemble and assemble, capable of facilitating steam turbine overhaul, good in radiating, high in overall structural strength, good in top evenness, strong in stability and high in torsional strength and bending strength.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a steam turbine cover, in particular to an assembled steam turbine cover. Background technique [0002] As the name implies, the steam turbine casing refers to the shell set on the steam turbine. Generally, the top beam and the side column are fixedly connected by welding or bolts, and then a top plate is installed on the top beam by welding or bolts, and on the side column. Installing the side plate by welding or bolts has many inconveniences in this steam turbine casing, for example, the whole casing needs to be cut open when maintenance is required, the steam turbine is lifted out, and the whole casing is re-welded and ground flat after maintenance. In addition, this kind of steam turbine casing also has: poor heat dissipation, lack of lighting facilities, inconvenient disassembly and assembly on site, poor flatness of the top of the casing, insufficient compact structure, poor...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned scheme has improved the problem of inconvenient disassembly and assembly of the existing steam turbine cover to a certain extent, but the solution still exists: unreasonable structural design, poor heat dissipation, poor flatness of the top of the cover, insufficient compact structure, poor overall stability, and low torsion resistance. , low bending strength, and insufficient aesthetics of the casing, etc.
