Youlian ultrasonic gas cylinder inspection system is used for the automatic detection of ultrasonic defects of pressure cylinders, aluminum cylinders, seamless steel pipes and other workpieces. Other sizes need to be customized)
The detection methods of gas cylinders are shear wave circumferential and axial flaw detection methods. Water spray flaw detection is to place the probe at a certain height above the gas cylinder, spray water to form a water layer, and use the longitudinal wave to obliquely enter the water/steel interface. When the incident angle is appropriate, pure shear wave detection can be realized in the gas cylinder.
The detection process adopts spiral scanning, while ensuring 15% repeat coverage.
Perform two-way (longitudinal and lateral) ultrasonic flaw detection and thickness measurement on the straight section of the gas cylinder and the seamless steel tube.
Realize automatic flaw detection process: automatic feeding, automatic coupling, automatic scanning, automatic recording, automatic alarm (including defect alarm and wall thickness reduction alarm), automatic marking, automatic discharge, automatic sorting, automatic storage.
Overall structure diagram
The testing instrument adopts U-Link MCH, UISM multi-channel instrument, and adopts line focusing water immersion probe.
Equipment automatic control and manual control functions:
It can be set by software, and the detection process can be manually controlled or the system can automatically complete the pipeline work according to the detection process.
A scan, B scan display function during the detection process:
In the process of adjusting the detection parameters, the A-scan waveform of each channel can be selectively displayed; in the process of flaw detection, the A-scan waveform of each channel is displayed in real time, and the number and position of the detected defects can be automatically judged to form a B-scan image.
Parameter adjustment function:
Including gain, delay, range, frequency band, damping, noise reduction level and other parameter adjustment, a water layer wave tracking, alarm door setting function, in the process of flaw detection, read the water layer wave data once according to the set water layer wave gate , and according to the relative offset, set the alarm door position, monitor the designated area, and alarm the waveform exceeding the standard.
Detecting process storage calling function:
It can store the detection process of gas cylinders of various specifications, and can be called for daily flaw detection.
Realize automatic flaw detection process:
Automatically control and detect workpiece feeding, workpiece lifting, workpiece rotation, probe position, water spray coupling, probe movement detection, probe lifting, workpiece discharge, and defect alarm.
Automatically store, retrieve, and call inspection data according to batches:
After the gas cylinder inspection is completed, it can be classified by batch, and the inspection data of each gas cylinder workpiece can be stored separately according to the bottle number. The file name can clearly indicate whether the test result is normal or defective. For defective data files, the data can be opened and the defective echo can be played back.
Youlian ultrasonic gas cylinder inspection system has flexible operation and high defect detection sensitivity on site; the B-scan graphic display of defects is intuitive, which is convenient for operators to locate defects; the inspection data can be stored for a long time, which is conducive to later data retrieval and inspection results retrospectively.
