ANALYSIS OF CURRENT METHODS FOR LEAKAGE PART DETECTION
International Journal of Mechatronics and Applied Mechanics · 2021
There is a constantly growing need for products and technologies that for their realisation require hermetically closed elements, vessels and tubes.Envelopes with greater or smaller vacuum tightness had to assure a satisfactory isolation between external atmosphere and inside over-or under pressure.Critical leak spots in closed systems are usually: connections, gaskets, welded and brazed joints, defects in material etc. Regarding to quality demands in different production processes, technical people very relate to standards for tightness testing.With the view of stating if an element or system meets with the corresponding standards, we have to be familiar with the procedures relating with the following aspects:-question if there is a leakage or not -settlement of the leak size -detection of leak location For solving the mentioned problems, different treatments and techniques are known, but among them there is no a universal method.Each testing is suitable for a selected leak rate only, or for fixed forms and technologies.Our article presents the leak types, their sizes and various leak detection techniques.
