Problems solved by technology

[0005] In the prior art, defects or failures of different components of the turbogenerator set have a corresponding impact on the operating state of the unit. For example, when the shaft speed is insufficient, it may be due to insufficient steam pressure from the nozzle, or it may be due to the impeller The moving blades above are deformed to a certain extent at high temperature, resulting in insufficient force pressure; for this reason, we provide a force fault diagnosis system for steam turbine impeller structure to solve the above problems

Embodiment Construction

[0052] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0053] It should be noted that when an element is said to be "disposed on, provided with" another element, it may be directly on the other element or there may also be an intermediate element. A component, it can be directly connected to another component or there may be an intermediate component at the same time. "Fixed connection" means fixed connection. There are many ways of fixed connection, which are not within the scope of protection of this article. The term used in this article "Vertical", "horizontal", "left", "right" and similar expressions are for the purpose ...

Abstract

The invention discloses a turbine impeller structure stress fault diagnosis system. The turbine impeller structure stress fault diagnosis system comprises an impeller arranged in a shell, an outer impeller is integrally arranged on the outer ring of the impeller, a control cavity is formed in the outer impeller, a moving blade is arranged in the control cavity, an extending groove allowing the moving blade in the control cavity to movably penetrate through and extend out to the outer ring of the outer impeller is formed in the surface of the outer ring of the outer impeller, a monitoring unit used for monitoring the rotating speed of a shaft is arranged on a baffle, the monitoring unit can use a speed sensor and other devices, and when the monitoring unit monitors that the rotating speed of the shaft is insufficient, it can be determined that the turbine impeller structure stress has a fault.

Description

technical field [0001] The invention relates to the technical field of a force fault diagnosis system for a steam turbine impeller structure, in particular to a force fault diagnosis system for a steam turbine impeller structure. Background technique [0002] Turbogenerator refers to a generator driven by a steam turbine, which uses steam as a working medium to convert heat energy into electrical energy. It has been widely used in power systems. [0003] Among them, steam turbines can be divided into low-pressure steam turbines, medium-pressure steam turbines, high-pressure steam turbines, ultra-high pressure steam turbines, subcritical steam turbines, supercritical steam turbines and ultra-supercritical steam turbines according to the intake parameters. [0004] The basic working principle of the steam turbine (impulse type) is: when the steam expands and sprays out from the nozzle, it converts the heat energy of the steam into kinetic energy, then impacts the blades to con...
