Multifunctional steam turbine inner cylinder

Abstract

The invention discloses a multifunctional steam turbine inner cylinder, and belongs to the technical field of steam turbines, the multifunctional steam turbine inner cylinder comprises an inner cylinder main body, the inner cylinder main body comprises a partition plate sleeve, a steam retaining ring, a steam chamber and a steam seal body, the steam chamber is integrally formed at one end of the partition plate sleeve in a casting mode, and the steam seal body is integrally formed at one end in the steam chamber in a casting mode. By integrating a plurality of components such as the partition plate sleeve, the steam retaining ring, the steam chamber and the steam seal body, the split type components can be integrally cast into one component, the total size is greatly reduced, production materials are saved, the space position of a steam turbine is also saved, production and machining can be completed at a time, and the machining time is shortened. And meanwhile, supporting columns required for mounting and fixing are reduced, so that the mounting is simpler and more convenient, the mounting time is saved, and the mounting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of steam turbines, in particular to a multifunctional steam turbine inner cylinder. Background technique [0002] The steam turbine, also called the steam turbine engine, is a rotary steam power device. The high-temperature and high-pressure steam passes through the fixed nozzle and becomes an accelerated air flow, and then sprays onto the blades, so that the rotor equipped with blade rows rotates and works externally. The steam turbine is a modern The main equipment of the thermal power plant is also used in the metallurgical industry, the chemical industry, and the ship power plant. The interior includes partition sets, steam retaining rings, steam chambers, steam seals and other components; [0003] Existing partition sleeves, steam retaining rings, steam chambers, steam seals and other components are generally independent components, which need to be casted and formed separately during manufacture, and t...

AI Technical Summary

Problems solved by technology

[0003] Existing partition sleeves, steam retaining rings, steam chambers, steam seals and other components are generally independent components, which need to be casted and formed separately during manufacture, and then processed on machine tools separately. During installation, they need to be installed one by one, positioning and centering multiple times , takes more time and costs more

[0004] In addition, in order to prevent the components from interfering with each other during installation, there are usually gaps between the components, so that the volume of the components installed together is large and wastes space
