Abstract

The present invention provides a system for sensing a shifting of a drive ring, a compressor, and a gas turbine. The system for sensing a shifting of a drive ring comprises: a compressor housing; at least one drive ring, wherein the drive ring is installable on the compressor housing, and is disposed on the compressor housing with a spacing, and the drive ring is provided with at least one installation hole, wherein the installation hole extends along a radial direction of the drive ring; and at least one sensor, wherein the sensor is configured to be located in the corresponding installationhole, and is used to sense the spacing between the drive ring and the compressor housing in real time. The system for sensing a shifting of a drive ring, the compressor, and the gas turbine of the present invention have the advantages of simple structures and relatively low costs.

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,...
