Problems solved by technology

However, the crystal and temperature-indicating paint can only record the highest temperature during the entire test process, and cannot measure the temperature of various working conditions
And for crystal temperature measurement, the installation needs to process small holes in the disc body, which will affect the fatigue life of the disc body
For the temperature measurement of the temperature display paint, the test results need to be manually compared with the spectrum, and the error is large

Abstract

The invention provides a novel lead structure for testing the temperature of a compressor rotor disc body. The lead structure comprises an inner shaft (1), a supporting ring (2), an outer shaft (3), alead pin (4), a disc body (5), a testing lead (6), an electricity leading device (7) and a temperature sensor (8). According to the structure, the transient temperature of the disc body in the test process is measured under the conditions of not changing the real working environment of the disc body and not damaging the disc body.

Description

technical field [0001] The invention belongs to the field of testing the rotor of a gas turbine engine compressor component, and in particular relates to a lead wire structure for testing the temperature of a compressor rotor disc. Background technique [0002] Gas turbine engine compressor rotor disks, especially the last stage rotor disks, work in high temperature and high stress environments. Accurately measuring the temperature of the disk is of great significance for evaluating the strength and life of the disk, and for calibrating the numerical calculation method of the temperature field. [0003] For the last-stage rotor of a multi-stage compressor, if the traditional thermocouple is used for measurement, it is very difficult to wire the lead wires through the drum and enter the lead wires in the front section of the compressor. Therefore, crystals and temperature-indicating paints are widely used in China to measure temperature. However, the crystal and temperature...
