Definitions

  • the present invention relates to a leakage test mechanism developed for determining whether there are faults like cracks, holes, etc. in closed storage products (vessels), particularly used for fluids and produced by means of various raw materials, after the production of said closed storage products, and for measuring the leakage amount.
  • One of these tests is the leakage test made for determining whether there are any cracks and/or holes on the product.
  • these leakage tests can be made by means of air pressure formed inside the vessel, by means of following up painted liquid, by means of immersion into water and applying air pressure and following up bubbles, by means of helium spectroscopy and by means of gas mass spectroscopy.
  • the methods like air pressure method, painted liquid follow-up method and underwater bubble follow-up method are generally sufficient in terms of precision, and the costs of said methods are relatively lower.
  • these tests are realized manually, and leakage detection may not be accurate since the accuracy of the test result depends on the carefulness and assessment of the operator. The test result depends on the subjective assessment of the operator carrying out the test. Moreover, it is difficult to record the results.
  • the present invention relates to a leakage test mechanism developed for determining whether outward fluid leakage occurs through various closed products, for instance, fuel tanks, radiators, for eliminating the above mentioned disadvantages and for bringing new advantages to the related technical field.
  • the main object of the present invention is to provide a leakage test mechanism where the error rate is reduced and which can be traced and assured.
  • the present invention is a leakage test mechanism comprising a hose connected to a vessel from one end and connected to an air supply from the other end, in order to determine whether outward fluid leakage occurs through said vessel having an air input mouth.

  • a process terminal having a control program which compiles the information received from the data recorder and which calculates and gives out the result of whether
  • said sound / vibration sensor is a microphone which can function under water and above water and which can sense said vibration frequencies.
  • said sound / vibration sensor comprises a sound/vibration filter which filters the detected sounds / vibrations and which provides measurement of only the leakage sound / vibration.
  • said sound/vibration filter is positioned inside the data recorder.
  • said sound/vibration filter is positioned inside the process terminal.
