Description

Apparatus for mechanical test of rotor bore}

The present invention relates to a rotor core hole histological examination apparatus, and easy to inspect the inner circumferential surface of the rotor, and to a rotor core hole histological examination apparatus that can improve the reliability of the inspection.

The rotor, which is the rotating part of the motor or generator, has a working condition of 500 ℃ or higher. It is a high-temperature, high-speed rotor that operates under very bad conditions. Therefore, if the damage occurs by operating easily exposed to thermal fatigue damage, creep damage, etc., the transition rate of the damage from microcracks to macrocracks is much faster than other facilities. If the rotor is damaged, it poses a risk that can lead to a very serious accident. In fact, such cases have been reported in foreign countries, and in Korea, there have been cases of large-scale accidents in which the cracks started on the inner circumference of the rotor and fly through the case.

In general, external tests of the rotor include the Ultrasonic Test (UT), the Penetrant Test (PT), the Magnetic Paticle (MT), and the Eddy Curent Test (ECT). Non-destructive testing is used to inspect the presence of cracks, and through histological examination to determine the degree of material degradation and creep damage.

The inner circumferential surface of the rotor is inspected for the degree of cracking and oxidation scale through special equipment capable of ultrasonic inspection and eddy current inspection among the non-destructive methods as described above. Biopsy has not been used in Korea yet.

The lack of biopsy, one of the major damage factors for the life assessment of the rotor, is very unstable. Therefore, the inspection of the inner circumference of the rotor is a mandatory inspection item, and it is necessary to develop a device for this purpose.
