Detection of internal defects in castings
Equipment name: X-ray flaw detector
Basic working principle: this controller adopts a single and semi-controlled rectifier module. The rectified voltage changes into a smooth dc voltage after passing through the LC wave circuit. The voltage can be converted into a variable frequency unidirectional pulse through the SCR chopper loop and sent to the high-voltage pulse transformer as the power source of the X-ray generator. The milliampere stability unit can change the frequency of single pulse with the increase or decrease of the filament voltage of the X-ray tube to ensure the stability of the current of the X-ray tube. The kv regulating unit can continuously adjust the tube voltage to suit the requirements of different materials.
