Ultrasonic flaw detector CUD WiFi

Research axes without disassembling

The system has been designed on the basis of specifically formulated for the needs of potential customers and it is composed of several elements listed in Section A. The main element of the system is a flaw CUD WiFi discussed here . It is a structure having some specific solutions of the original, and such a solution is not offered on the market by others.

The system has several features that allow the general characteristics:

  • accelerate research and reduce their costs through automation and mechanization of all basic operations;
  • possibility to research without disassembled axis, vehicles without excluding them from exploitation, and partially disassembled and completely disassembled for research on special positions;
  • authentication of research by maximizing the independence of the test result on the subjective judgment of the operator, by automating and easily determine the repeatability research;
  • digital record of the entire course of research and archiving;
  • mobility devices and the ability to use them not only on the test bench, but also quite any other conditions;
  • the complexity of the research does not exceed the range operator certificate I and II according to PN EN 473 or ISO 9712 (However, the required computer skills at a basic level);
  • A visualization, and special flat and spatial (Fig. 4, left);
  • possibility of expansion and the system at any time and in a wide range of.

The device consists of a shield of probes, flaw detector and bracket-adapter. Moreover, it may be equipped with a ring with the probes, as well as other research probes (e.g., welded connection). Shield of ultrasonic probes (Figure 1 and Figure 2) is used for testing, from the carrier face. Probes are placed on the target at distances resulting from the geometric analysis in a sustainable manner. The shield is designed individually for each type of axle depending on its geometrical dimensions. The shield is also arranged normal to the research probe along the axis. Also mounted device for measuring the rotation angle (inclinometer), making it possible to record the course of the study.

Rys. 1. Widok ekranu w czasie osi przy użyciu defektoskopu bezprzewodowego widoczne:
Lewa górna czę¶ć przedstawia ekran defektoskopu z aktualnym wskazaniem (typ A), prawa strona reprezentuje zarejestrowane amplitudy obwodu osi , dolna w strefie na długo¶ci osi. Zobrazowanie dotyczy dwóch nacięć i pokazanych jako echo w skali procentowej wysoko¶ci ekranu dla badanego przekroju w funkcji k±ta. W podanym przykładzie s± dwa nacięcia wzorcowe różni±ce się głęboko¶ci± o 0,5mm.

Poszczególne okręgi na zobrazowaniu (Rys. 1.) oznaczaj±:

  • kolorem szarym oznaczono powierzchnię zewnętrzn± badanej osi (odpowiadaj±c± amplitudzie 0%, amplituda 100% oznacza srodek koła);
  • kolorem zielonym oznaczono próg rejestracji ustawiony na 20% wysoko¶ci ekranu. Wszystkie wskazania znajduj±ce się w zasięgu markera powyżej tego progu zostan± zarejestrowane;
  • kolorem czerwonym oznaczono próg akceptacji (40% wysoko¶ci ekranu) i ewentualne jego przekroczenia. Wszystkie wskazania powyżej progu akceptacji należy traktować jako potencjalne wskazania od nieci±gło¶ci nieakceptowanych;
  • kolorem niebieskim oznaczono natomiast przebadane miejsca na obwodzie osi wraz z zaznaczeniem amplitud ewentualnych wskazań powyżej progu rejestracji.
