Supporting platform system for steam turbine generator unit arranged at high position

Abstract

The invention discloses a supporting platform system for a steam turbine generator unit arranged at a high position. Vibration influences to a supporting platform structure when steam turbine generators run normally and under various unfavorable work conditions can be determined by means of calculation while processing set-up and safe and stable running conditions of the steam turbine generator unit arranged at the high position are met, and accordingly feasibility and applicability of high-position arrangement of the steam turbine generator unit arranged at the high position are judged. The technical scheme includes that the system comprises a table board, a vibration isolation system and a platform main body structure, the table board is used for holding the steam turbine generator unit arranged at the high position, the vibration isolation system is mounted below the table board, and the platform main body structure is mounted on the ground and used for shelving the vibration isolation system.

Description

technical field [0001] The invention relates to a structural arrangement scheme of a supporting platform, in particular to the realization of a platform system supporting a steam turbine generator set arranged at a high position. Background technique [0002] For the specific implementation of the high-position turbo-generator set, please refer to the Chinese invention application for a new type of turbo-generator set (patent number: CN200710040128.0). This invention arranges the high and low shafts staggeredly, which significantly reduces the length of the expensive high-temperature and high-pressure steam pipelines in the steam pipeline system and the pressure drop and heat dissipation loss of the pipeline system, improves the working capacity of the unit, and reduces the heat dissipation. The gas storage capacity of the thermal system and the adjustment inertia of the unit can fully reflect the economy of the twice-reheated unit. The invention utilizes the existing power...

Problems solved by technology

However, the steam turbine generator adopts a high-level layout. If the original support platform layout is still used, one can imagine a shelving platform with a width of only 12-18m and a height of more than 30m. Increase the width, because it needs to be separated from the traditional main factory building, the turbine support platform is extremely large, and such a structure is extremely uneconomical and reasonable
