Wherein, the nuclear power station main pump flywheel 200 in in-service stage refers to the nuclear power turn for being installed and having come into operation
Main pump flywheel.It is blocked since the surface of the nuclear power station main pump flywheel 200 in in-service stage has other component, for convenience to nuclear power
Main pump flywheel of standing 200 carries out defects detection, and the surface of nuclear power station main pump flywheel 200 is provided with inspection hole 210.When needing nuclear power station
When main pump flywheel 200 carries out defects detection, it is only necessary to protrude into inspection hole 210 ultrasonic listening mould group 100, and make ultrasonic wave
Detect the position to be detected progress scanning that mould group 100 is directed at nuclear power station main pump flywheel 200.Specifically in the present embodiment, core
The position to be detected of power station main pump flywheel 200 is the position of center keyway on nuclear power station main pump flywheel 200.
Display screen and ultrasonic listening mould group 100 communicate to connect.Ultrasonic fault detection system is according to ultrasonic listening mould group 100
The reflection echo received forms impulse waveform on a display screen, to judge position and the size of defect.Specifically in the present embodiment
In, display screen is fluorescent screen.
Ultrasonic fault detection system carries out the process of defects detection to the position to be detected of nuclear power station main pump flywheel 200 are as follows: before this
Ultrasonic listening mould group 100 is protruded into inspection hole 210, and issues ultrasound to the position to be detected of nuclear power station main pump flywheel 200
Wave, while receiving reflection echo；It is the axial movement ultrasonic listening mould group 100 along inspection hole 210 again, so that ultrasonic examination
System forms impulse waveform according to the reflection echo that ultrasonic listening mould group 100 receives on a display screen；Followed by observation is aobvious
The variation of impulse waveform in display screen, and according to the variation of impulse waveform to determine whether existing defects.
Also referring to Fig. 3 to Fig. 5, the ultrasonic listening mould group 100 in the utility model preferred embodiment includes probe
