OKOndt SNK KB-13 Automated Wheel & Rim UT System

OKOndt SNK KB-13 Automated Wheel & Rim UT System

Overview

The SNK KB-13 System is intended to be installed in the line control assembly with of wheel and rim products. Assures wheel and rim testing is in compliance with AAR M 107/208 and EN 13262, UIC 810-1, ISO 5948, with the subsequent return of the tested products to the finished products acceptance stand. The SNK KB-13 System performs ultrasonic testing of the car wheel/wheel tread in axial and radial directions and testing of the wheel hub in two opposite directions by the ultrasonic method. Subsequent documentation of test results are transferred to the server along with imaging of the test process, the test results verification for compliance with the standard, and test results data.

Finished and machined railway wheels and rims with the following parameters can be used in the KB-13 System:

  • wheel/rim weight — from 200 kg to 1300 kg
  • wheel/rim diameter — from 700 kg to 1350 kg
  • rim width — from 80 mm to 160 mm
  • rim thickness — from 35 mm to 150 mm

 

 

 

 

Features

  • Test throughput – from 10 wheels/rims per hour
  • Readjustment time and preparation for another wheel/rim type scanning at given software configuration for a specific assortment is not more than 10 min. For another assortment when the software is not configured it is not more than 120 min

  • Tests the tread of a car wheel in axial and radial directions

    • Minimal defect diameter – 1 mm, Minimal depth of the defect – 5 mm

  • Tests wheel hubs in the axial direction

    • Minimal defect diameter – 3 mm, Minimal depth of the defect – 5 mm

  • Test configurations that allow to limiting defect quantity and the distance between the defects in compliance with the standards

  • Evaluation of the defects parameters (defect depth, approximate coordinate, amplitude, equivalent defect size, equivalent area in millimeters)

  • Defect parameters display in the “Defects Table/Defectogram”, in the A-Scan, B-Scan, and C-Scan, saving the data to the System memory, with ability to print them out

  • Light and sound Defect Alarm

  • Various test configurations can be saved with different probe sets, coordinates, travel speeds

  • Good product and defect marking with paint in order to confirm the defect further in manual mode

  • Test results (protocols) output in electronic version in .xls or .pdf formats with ability to print them out on paper

  • Operated by dedicated software which enables automatic management of the System mechanical units, as well as the test results reading, processing, and recording

  • System design ensures the safety of maintenance personnel with automatic blocking, alarm, and emergency shutdown
