Abstract

The present invention provides a drive ring offset sensing system, a compressor, and a gas turbine. The drive ring offset sensing system includes: a compressor casing; at least one drive ring, and the drive ring can be Installed on the compressor housing and spaced apart from the compressor housing, the drive ring is provided with at least one installation hole, and the installation hole extends along the radial direction of the drive ring; at least one sensor, the The sensors may be arranged in the corresponding installation holes for real-time sensing of the distance between the drive ring and the compressor casing. The drive ring offset sensing system, air compressor and gas turbine of the present invention have the advantages of simple structure and low cost.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to a drive ring offset sensing system, a compressor and a gas turbine. Background technique [0002] A gas turbine is a rotary power machine that uses a continuous flow of gas as a working medium to convert heat energy into mechanical work. A gas turbine generally consists of three major components: a compressor, a combustor and a turbine. When working, the compressor inhales air from the external atmosphere, and compresses it step by step through the axial flow compressor to pressurize it, and the temperature of the air increases accordingly; the compressed air is sent to the combustion chamber and mixed with the injected fuel to generate High-temperature and high-pressure gas; then the high-temperature and high-pressure gas enters the turbine part and expands to do work, pushing the turbine part to drive the compressor and the external load rotor to rotate together at high speed,...
