Description

Technical Field

[0002] A steam turbine, also known as a steam turbine engine, is a mechanical device that uses high-temperature and high-pressure steam to generate accelerated airflow through a nozzle, thereby driving a rotor equipped with a row of blades to rotate and perform work externally. The working principle of a steam turbine is to convert a low-temperature and low-pressure liquid into a high-temperature and high-pressure liquid through a mechanical air compressor, and then use an impeller to discharge the high-pressure and low-temperature liquid to rotate a mechanical shaft to provide power. The steam turbine feedback device plays a vital role in the steam turbine regulation system. The main function of the feedback device is to maintain the stability of the regulation, which helps to maintain the stability and reliability of the steam turbine during operation. In related technologies, the feedback device is mostly installed directly inside the steam turbine, which is not easy to replace when damaged. At the same time, the feedback range is small and the detection position cannot be flexibly adjusted. Utility Model Content
